coronavirus variant
Now that Omicron is here, what can the early data out of South Africa tell us?
Two members of the Bangladesh women’s cricket team, which remains in quarantine since returning from Zimbabwe amid the Omicron scare late last month, were confirmed on Saturday as the country’s first identified cases of the latest coronavirus variant of concern.
Since first being identified by South African doctors in the province of Gauteng, which includes Johannesburg in mid-November, Omicron has spread quickly around the globe, and was said to be present in at least 57 countries by the WHO as of Thursday – before Bangladesh confirmed its cases.
Africa recorded more than 107 000 cases in the week ending on 5 December, up from around 55 000, according to WHO – up 93% over the previous week. Countries in southern Africa, where the variant is known to have been in circulation since early November, recorded the highest increase with a 140% hike mainly driven by an uptick in South Africa.
Scientists around the world are poring over the early data out of SA in order to gain a grasp of what to expect in the event of a new wave of infections driven by Omicron. At this stage, the weight of evidence indicates although an Omicron wave may well be inevitable, it is likely to be typified by milder cases, with less severe disease than what was witnessed during the Delta wave.
Data which looked at hospitalisations across South Africa between 14 November and 4 December found that ICU occupancy was only 6.3% – which the WHO says is “very low” compared with the same early period of the wave linked to the Delta variant in July.
Out of more than 1200 admissions, 98 were receiving supplemental oxygen and only four were on ventilation. Most of the people admitted to the health facilities were under the age of 40 – this isn’t unusual, as the early part of a wave is often fuelled by the young, who tend to be more outgoing, as well as less vaccinated.
WHO has warned that as the clinical profile of patients changes, the impact of Omicron may change. This would apply even more in countries with a different demographic profile to South Africa, which has a very young population.
But we found some reassuring similarities between the demographic profiles of South Africa and Bangladesh, and even the proportion of the population in each country vaccinated, which makes a deep dive into the early data out of South Africa much more worthwhile.
Similarities between SA and BD
Statistics South Africa, which is a government agency, estimated the population of South Africa was 58.8 million in 2019. In this regard it is dwarfed by Bangladesh, where the population in 2019 was 164.6 million, as per the Bangladesh Bureau of Statistics. But there the dissimilarities end.
According to the World Population Review, which uses projections of the latest United Nations data, the median age in the two countries is very similar – 27.1 in South Africa (26.9 for males, 27. 3 for females), and 26.7 in Bangladesh (26 for males, 27.3 for females).
The two countries also have very similar population pyramids (see image), showing the distribution of the population through different age groups. Using World Bank data, we find there are similarities in the age structures of the two nations too.
In South Africa, 28.8% of the population is aged between 0-14 years; 65.6% is aged between 15-64; and 5.5% are 65 and over.

In Bangladesh, 26.8% of the population falls in the 0-14 years category; 68% are between 15-64; and 5.2% are 65 and over.
There are striking similarities in the vaccination numbers too. In South Africa, 41% of the adult population has had at least one dose of the vaccine. In Bangladesh, a greater percentage of the population targeted for vaccination (which includes adults plus some other groups such as students) has had at least a single dose – 52%.
South Africa however has done a better job of fully vaccinating its adult population – 36% are double-jabbed. In Bangladesh, 32% of the targeted population have had their two doses of the vaccine.
South Africa’s Fourth Wave
In order to assess the situation in South Africa, we’ll look at data from the country’s National Institute of Communicable Diseases (NICD), a division of the country’s National Health Laboratory Service, hospital groups, and statements of senior healthcare professionals.
The first thing to note is that cases in South Africa are undoubtedly surging. The country confirmed 22,391 new cases on Thursday, 19,018 on Friday, and 17,154 on Saturday, up from about 200 per day a few weeks ago – interestingly, about the level Bangladesh finds itself at present.
The positivity rate hit 29.8% on Thursday, a sharp increase from 1.2% reported during the first week of November.
The new surge has infected 90,000 people in the past month, Minister of Health Joe Phaahla said Friday.
“Omicron has driven the resurgence,” Phaahla said, citing studies that say 70% of the new cases nationwide are from omicron.
The R value, signifying the coronavirus reproduction rate - the number of people likely to be infected by one person – for South Africa’s current wave is 2.5, which is very high, and the highest that South Africa has recorded during the pandemic.

Omicron coronavirus variant found in multiple US states
The omicron variant of COVID-19, which had been undetected in the U.S. before the middle of this week, had been discovered in at least five states by the end of Thursday, showing yet again how mutations of the virus can circumnavigate the globe with speed and ease.
Just a day after the first known U.S. case was found in California, tests showed the omicron variant had infected at least five people in the New York City metropolitan area, plus a man from Minnesota who had attended an anime convention in Manhattan in late November.
A Colorado woman who had recently traveled to southern Africa, a Hawaii resident with no recent travel history, and another California resident who traveled to South Africa last month also were infected by the variant, officials said.
Much remains unknown about omicron, including whether it is more contagious, as some health authorities suspect, whether it can thwart vaccines and whether it makes people as sick as the original strain.

Health officials in each state said there was no cause for undue alarm. But the spread of the cases, some involving people who hadn't been away from home recently, meant the variant was likely already circulating domestically in some parts of the U.S.
“We gotta assume there’s a lot more behind that and that it has been here for a meaningful amount of time,” New York City Mayor Bill de Blasio said at a news conference with Gov. Kathy Hochul.
The infected New Yorkers included a 67-year-old woman on Long Island who had recently traveled to South Africa, residents of Brooklyn and Queens and another case possibly linked to travel. At least one person had received a dose of a COVID-19 vaccine but officials did not have details about the vaccination status of the four other cases.
In Minnesota, health officials said a man who had not traveled outside the U.S. began experiencing symptoms the day after attending the Anime NYC 2021 convention in New York City. Minnesota Health Commissioner Jan Malcolm said it's likely the man contracted COVID-19 at the convention, but officials did not know for sure.
Officials in New York said they were working to trace attendees of the convention, which was held Nov. 19-21 and drew about 50,000 people, according to event organizers. Attendees were required to wear masks and show proof of having received at least one dose of a COVID-19 vaccine.
It was held at the Jacob K. Javits Convention Center as New York City prepared to host the annual Macy’s Thanksgiving Day Parade and braced for throngs of tourists to return after the U.S. opened up to vaccinated international travelers.

City Health Commissioner Dave Chokshi urged people who attended the event to get tested.
"This is not just due to people who are traveling to southern Africa or to other parts of the world where omicron has already been identified,” Chokshi said Thursday.
The Minnesota man began experiencing mild symptoms Nov. 22. He had been vaccinated and received a booster shot in early November, according to health officials in his home state. He sought COVID-19 testing Nov. 24, and his symptoms have subsided, officials said.
Nov. 22 was the same day the person infected in the first California case returned to the U.S. from South Africa. The California traveler, who was vaccinated, developed mild symptoms and tested positive Monday. The second person in the state didn’t need medical care and was also vaccinated.
The unvaccinated adult infected with the variant in Hawaii had gotten COVID-19 a year ago. The person isn’t currently hospitalized and had “mild-to-moderate” symptoms including headache, body aches and cough, Hawaii Epidemiologist Dr. Sarah Kemble said.
She wouldn’t identify the patient other to say the person lives on the island of Oahu.
Omicron is classified by the World Health Organization as a “variant of concern” as scientists work to determine how it may compare with the predominant delta variant in terms of transmissibility and severity. Scientists also are studying the degree to which existing vaccines and therapies protect against omicron.
Scientists in South Africa first reported it, but the samples came from several countries in southern Africa. And health officials in the Netherlands now say it was found there prior to the South Africa detection.
As comfort over air travel returns, it’s inevitable that new variants like omicron will spread from country to country and state to state, said professor Danielle Ompad, an epidemiologist at New York University’s School of Global Public Health.
“We shouldn’t panic, but we should be concerned,” she said.
Hochul said the case involving the Minnesota visitor underlined the need for everyone who is eligible to get vaccinated against COVID-19 or receive a booster shot if they have not already.
“There is one way to address this — New Yorkers, get vaccinated, get boosted, and get ready,” the Democrat said.

What we know and don’t know on new COVID variant
South African scientists identified a new version of the coronavirus that they say is behind a recent spike in COVID-19 infections in Gauteng, the country's most populous province.
It's unclear where the new variant first emerged, but scientists in South Africa alerted the World Health Organization in recent days, and it has now been seen in travelers arriving in several countries, from Australia to Israel to the Netherlands.
On Friday, the WHO designated it as a "variant of concern," naming it "omicron" after a letter in the Greek alphabet.
WHAT DO WE KNOW ABOUT OMICRON?
Health Minister Joe Phaahla said the variant was linked to an "exponential rise" of cases in the last few days.
From just over 200 new confirmed cases per day in recent weeks, South Africa saw the number of new daily cases rocket to more than 3,200 Saturday, most in Gauteng.
Struggling to explain the sudden rise in cases, scientists studied virus samples and discovered the new variant. Now, as many as 90% of the new cases in Gauteng are caused by it, according to Tulio de Oliveira, director of the KwaZulu-Natal Research Innovation and Sequencing Platform.
WHY ARE SCIENTISTS WORRIED ABOUT THIS NEW VARIANT?
After convening a group of experts to assess the data, the WHO said that "preliminary evidence suggests an increased risk of reinfection with this variant," as compared to other variants.
That means people who contracted COVID-19 and recovered could be subject to catching it again.
The variant appears to have a high number of mutations — about 30 — in the coronavirus' spike protein, which could affect how easily it spreads to people.
Sharon Peacock, who has led genetic sequencing of COVID-19 in Britain at the University of Cambridge, said the data so far suggest the new variant has mutations "consistent with enhanced transmissibility," but said that "the significance of many of the mutations is still not known."
Lawrence Young, a virologist at the University of Warwick, described omicron as "the most heavily mutated version of the virus we have seen," including potentially worrying changes never before seen all in the same virus.

WHAT'S KNOWN AND NOT KNOWN ABOUT THE VARIANT?
Scientists know that omicron is genetically distinct from previous variants including the beta and delta variants, but do not know if these genetic changes make it any more transmissible or dangerous. So far, there is no indication the variant causes more severe disease.
It will likely take weeks to sort out if omicron is more infectious and if vaccines are still effective against it.
Peter Openshaw, a professor of experimental medicine at Imperial College London said it was "extremely unlikely" that current vaccines wouldn't work, noting they are effective against numerous other variants.

Dutch, Australians find omicron variant: others halt flights
The Netherlands confirmed 13 cases of the new omicron variant of the coronavirus on Sunday and Australia found two as the countries half a world apart became the latest to detect it in travelers arriving from southern Africa.
Israel decided to bar entry to foreigners and Morocco said it would suspend all incoming air travel from around the world for two weeks starting Monday — the most drastic of a growing raft of travel curbs being imposed by nations around the world as they scramble to slow the variant's spread.
Confirmed or suspected cases of the new variant have already emerged in several European countries, in Israel and in Hong Kong, just days after it was identified by researchers in South Africa. The "act first, ask questions later" approach reflected growing alarm about the emergence of a potentially more contagious variant nearly two years into a pandemic that has killed more than 5 million people, upended lives and disrupted economies across the globe.
While much remains to be learned about the new variant, researchers are concerned that it may be more resistant to the protection provided by vaccines and could mean that the pandemic lasts for longer than anticipated.
The Dutch public health authority confirmed that 13 people who arrived from South Africa on Friday have so far tested positive for omicron. They were among 61 people who tested positive for the virus after arriving on the last two flights to Amsterdam's Schiphol airport before a flight ban was implemented. They were immediately put into isolation, most at a nearby hotel, while sequencing was carried out.
Authorities in Australia said two overseas travelers who arrived in Sydney from Africa became the first in the country to test positive for the omicron variant. Arrivals from nine African countries are now required to quarantine in a hotel upon arrival. Two German states reported a total of three cases in returning travelers over the weekend.

Israel moved to ban entry by foreigners and mandate quarantine for all Israelis arriving from abroad.
"Restrictions on the country's borders is not an easy step, but it's a temporary and necessary step," Prime Minister Naftali Bennett said at the start of the weekly Cabinet meeting.
Dr. Ran Balicer, head of the government's advisory panel on COVID-19, told Israel's Kan public radio that the new measures were necessary for the "fog of war" surrounding the new variant, saying it was "better to act early and strictly" to prevent its spread.
Morocco's Foreign Ministry tweeted Sunday that all incoming air travel to the North African country would be suspended to "preserve the achievements realized by Morocco in the fight against the pandemic, and to protect the health of citizens." Morocco has been at the forefront of vaccinations in Africa, and kept its borders closed for months in 2020 because of the pandemic.
Dutch Health Minister Hugo de Jonge said he asked his country's public health institute for advice on whether additional travel restrictions are needed, but he wants to coordinate with his European Union counterparts because "I think those are really steps that we will have to take together."
Many countries have restricted or banned travel from various southern African countries — among the latest New Zealand, Thailand, Indonesia, Singapore, Sri Lanka, the Maldives, Saudi Arabia, Qatar and the United Arab Emirates. Places that already had imposed restrictions include Brazil, Canada, the EU, Iran, and the U.S. This goes against the advice of the World Health Organization, which has warned against any overreaction before the variant is thoroughly studied.
South Africa's government responded angrily to the travel bans, which it said are "akin to punishing South Africa for its advanced genomic sequencing and the ability to detect new variants quicker." It said it will try to persuade countries that imposed them to reconsider.
"Whilst we respect the right of all countries to take the necessary precautionary measures to protect their citizens, we need to remember that this pandemic requires collaboration and sharing of expertise," the minister for international relations and cooperation, Naledi Pandor, said in a statement.

The United States' top infectious diseases expert, Dr. Anthony Fauci, said he wouldn't be surprised if the omicron variant was already in the U.S., though it hasn't yet been detected there.
In Europe, much of which already has been struggling with a sharp increase in cases over recent weeks, officials also were on guard.
The U.K. on Saturday tightened rules on mask-wearing and on testing of international arrivals after finding two omicron cases. Spain announced it won't admit unvaccinated British visitors starting Dec. 1.
Italy was going through lists of airline passengers who arrived in the past two weeks after a business traveler who returned from Mozambique and landed in Rome on Nov. 11 tested positive for omicron. The Lazio region's top health official, Alessio D'Amato, said that "controls at airports, ports and train stations have been reinforced."
French Health Minister Olivier Veran said that, while his country had no confirmed cases yet, "it is probable that there currently are cases in circulation."
While it is not clear yet how existing vaccines work against the omicron variant, Veran said France isn't changing its strategy to fight the latest surge of infections driven by the delta variant, which centers on increasing vaccinations and boosters.
David Hui, a respiratory medicine expert and government adviser on the pandemic in Hong Kong, said that even though it is not clear if current coronavirus vaccines are effective against the new variant, the city's vaccination rate should be increased and booster doses should be implemented as soon as possible.
He said the two people who tested positive for the omicron variant had received the Pfizer shot and exhibited very mild symptoms, such as a sore throat.
"Vaccines should work but there would be some reduction in effectiveness," he said.

South African scientists detect new virus variant amid spike
A new coronavirus variant has been detected in South Africa that scientists say is a concern because of its high number of mutations and rapid spread among young people in Gauteng, the country's most populous province, Health Minister Joe Phaahla announced Thursday.
The coronavirus evolves as it spreads and many new variants, including those with worrying mutations, often just die out. Scientists monitor for possible changes that could be more transmissible or deadly, but sorting out whether new variants will have a public health impact can take time.
South Africa has seen a dramatic rise in new infections, Phaahla said at an online press briefing.
“Over the last four or five days, there has been more of an exponential rise,” he said, adding that the new variant appears to be driving the spike in cases. Scientists in South Africa are working to determine what percentage of the new cases have been caused by the new variant.
Currently identified as B.1.1.529, the new variant has also been found in Botswana and Hong Kong in travelers from South Africa, he said.
Also read: Can new variants of the coronavirus keep emerging?
The World Health Organization's technical working group is to meet Friday to assess the new variant and may decide whether or not to give it a name from the Greek alphabet.
The British government announced that it was banning flights from South Africa and five other southern African countries effective at noon (1200GMT) on Friday, and that anyone who had recently arrived from those countries would be asked to take a coronavirus test.
U.K. Health Secretary Sajid Javid said there were concerns the new variant “may be more transmissible” than the dominant delta strain, and “the vaccines that we currently have may be less effective" against it.
The new variant has a “constellation” of new mutations, said Tulio de Oliveira, from the Network for Genomic Surveillance in South Africa, who has tracked the spread of the delta variant in the country.
The "very high number of mutations is a concern for predicted immune evasion and transmissibility,” said de Oliveira.
“This new variant has many, many more mutations," including more than 30 to the spike protein that affects transmissibility, he said. "We can see that the variant is potentially spreading very fast. We do expect to start seeing pressure in the healthcare system in the next few days and weeks.”
De Oliveira said that a team of scientists from seven South African universities is studying the variant. They have 100 whole genomes of it and expect to have many more in the next few days, he said.
“We are concerned by the jump in evolution in this variant," he said. The one piece of good news is that it can be detected by a PCR test, he said.
After a period of relatively low transmission in which South Africa recorded just over 200 new confirmed cases per day, in the past week the daily new cases rapidly increased to more than 1,200 on Wednesday. On Thursday they jumped to 2,465.

The first surge was in Pretoria and the surrounding Tshwane metropolitan area and appeared to be cluster outbreaks from student gatherings at universities in the area, said health minister Phaahla. Amid the rise in cases, scientists studied the genomic sequencing and discovered the new variant.
“This is clearly a variant that we must be very serious about,” said Ravindra Gupta, professor of clinical microbiology at the University of Cambridge. “It has a high number of spike mutations that could affect transmissibility and immune response.”
Gupta said scientists in South Africa need time to determine if the surge in new cases is attributable to the new variant. “There is a high probability that this is the case," he said. “South African scientists have done an incredible job of identifying this quickly and bringing it to the world's attention.”
South African officials had warned that a new resurgence was expected from mid-December to early January and had hoped to prepare for that by getting many more people vaccinated, said Phaahla.
About 41% of South Africa's adults have been vaccinated and the number of shots being given per day is relatively low, at less than 130,000, significantly below the government's target of 300,000 per day.
South Africa currently has about 16.5 million doses of vaccines, by Pfizer and Johnson & Johnson, in the country and is expecting delivery of about 2.5 million more in the next week, according to Nicholas Crisp, acting director-general of the national health department.
“We are getting in vaccines faster than we are using them at the moment,” said Crisp. “So for some time now, we have been deferring deliveries, not decreasing orders, but just deferring our deliveries so that we don’t accumulate and stockpile vaccines.”
South Africa, with a population of 60 million, has recorded more than 2.9 million COVID-19 cases including more than 89,000 deaths.
To date, the delta variant remains by far the most infectious and has crowded out other once-worrying variants including alpha, beta and mu. According to sequences submitted by countries worldwide to the world’s biggest public database, more than 99% are delta.

'Dangerous period' with delta variant: WHO
The head of the World Health Organization says the world is in “a very dangerous period” of the COVID-19 pandemic, noting the more contagious delta variant is identified in nearly 100 countries.
At a press briefing on Friday, Tedros Adhanom Ghebreyesus said the delta variant, first found in India, is continuing to evolve and mutate, and it is becoming the predominant COVID-19 virus in many countries.
Also read: Delta variant exploits low vaccine rates, easing of rules
“I have already urged leaders across the world to ensure that by this time next year, 70% of all people in every country are vaccinated,” he said, adding that would effectively end the acute phase of the pandemic.
He noted 3 billion doses of vaccine have already been distributed and, “it’s within the collective power of a few countries to step up and ensure that vaccines are shared.”
Also read: What should I know about the delta variant?
Of the vaccine doses given globally, fewer than 2% have been in poorer countries. Although rich countries including Britain, the U.S., France and Canada have pledged to donate 1 billion COVID-19 vaccines, WHO estimates 11 billion doses are needed to immunize the world.

Bangladesh ill-equipped to cope with Delta variant of Covid: Experts
As the highly contagious Delta variant of Covid-19 has made its way into Dhaka and other districts from frontier ones, experts fear an impending health catastrophe in the coming weeks since there is no strict measure in place to stop it.
They said half-hearted preventive measures, lack of seriousness of local administrations, reopening of intra-district transport services and people’s apathy to maintain health safety guidelines are the major reasons behind the worsening Covid situation in the country.
The Institute of Epidemiology Disease Control and Research has recently found 80 percent of a randomly selected sample of 50 Covid patients infected with the Delta variant.
It also said the deadly variant has spread to parts of central Bangladesh, including the capital, while seven workers of Ashrayan Project in Nawabganj upazila of Dhaka have been detected with the same virus strain.
The sudden spike in virus cases has put a severe strain on four major hospitals ---Rajshahi Medical College, Khulna Medical College, Chapainawabganj and Kushtia General Hospital--with increasing patients from 11 nearby districts.
Also read: IEDCR study of 50 samples finds 40 are Delta
Experts said the government should immediately increase the number of beds, doctors and nurses and treatment facilities, in these hospitals to cope with the pressure of Covid patients.
The virus infection has been showing an upward trend in Rajshahi, Chapainawabganj, Dinajpur, Joypurhat, Naogaon, Kushtia, Jashore, Satkhira, Khulna, Bagerhat, Natore, Noakhali and Cox's Bazar districts for several days.

IEDCR study of 50 samples finds 40 are Delta
Delta, the Coronavirus variant first found in India, turned out to be 80% of some 50 genomes sequenced in Bangladesh since May 16 by IEDCR. There is also evidence of community transmission of the variant, according to research jointly carried out by IEDCR and IDSHI.
The study also identified one "unknown variant" and found 8 of the samples (16%) to be infected with the South African variant.
IEDCR and IDSHI collected and analysed 50 samples from across the country, including border districts and the capital since May 16.
The research also found 40 out of the total 50 cases as Delta variant, known as Indian variant, in samples collected from Chapainawabganj, Gopalganj, Khulna, Dhaka, Dinajpur, Gaibandha, Bagerhat, Jhenaidah and Pirojpur.

Also, among the 40 patients, eight were tested positive after returning from India while 18 others came in contact with overseas returnees although they did not travel abroad.
Meanwhile, among the samples collected, 14 infected people neither went abroad nor came in contact with people with travel history. So, it is clear that the Indian variant is being transmitted at the community level inside the country, the research said.
On May 8, the Indian variant was detected in Bangladesh for the first time. All of the infected people returned from the neighbouring country.
The "highly contagious" Indian Delta variant was first detected in October last year. The World Health Organization labelled it a "variant of concern."

As India surges, Bangladesh lacks jabs, faces virus variants
India’s surge in coronavirus cases is having a dangerous effect on neighboring Bangladesh. Health experts warn of imminent vaccine shortages just as the country should be stepping up its vaccination drive, and as more contagious virus variants are beginning to be detected.
On Saturday, health authorities said that for the first time, a coronavirus variant originally identified in India was detected in Bangladesh, without providing further details. For weeks, South African variants have dominated the samples sequenced in Bangladesh. There are concerns that these versions spread more easily and that first-generation vaccines could be less effective against them.
Experts say that declining infections in Bangladesh over the last two weeks compared to March and early April — for reasons that aren’t fully understood — provided the perfect opportunity for the nation to scale up vaccinations.
Also read: Bangladesh detects first case of Indian Coronavirus strain
“This is the time to vaccinate, keep infections low and make sure that new variants don’t emerge here,” said Senjuti Saha, a scientist at the Child Health Research Foundation in Bangladesh, who is also sequencing the virus.
However, India has banned the export of vaccines as it grapples with the crisis at home. The country’s Serum Institute was supposed to supply 30 million vaccine doses — 5 million doses a month — to Bangladesh by June. But the institute has only supplied 7 million doses and has suspended further shipments since February.
“It’s caused a real problem,” said Dr. A.S.M. Alamgir, a scientist with the government’s Institute of Epidemiology, Disease Control and Research.
Also read: Border with India to remain shut for another 14 days
Fearing shortages, the government late last month stopped allowing people to register for a first vaccine dose, and the administration of second doses is also being hampered.
The densely-populated country of 160 million is desperately seeking new avenues for vaccines other than India, and is attempting to produce Russian and Chinese vaccines at home by bringing technology from both countries. Bangladesh is expecting 500,000 doses of Chinese vaccines next week as a gift from Beijing, and has also sought help from the United States.
Dr. Mustafizur Rahman, a scientist of the Dhaka-based International Center for Diarrheal Disease Research, said threats from new variants remained a big concern, especially when vaccines are not available.

Although the border with India is closed to people, goods continue to cross. Virus sequencing in Bangladesh, like other countries including the U.S., has been scant. This means there could easily be blind spots.
“We can’t rule out that the Indian variant would not make a new wave in Bangladesh. We have a porous border with India,” Alamgir said.
Since March of last year, when the first COVID-19 case was detected in Bangladesh, the country has reported 770,842 confirmed virus cases and 11,833 deaths.

A nationwide lockdown has been extended until at least May 16, but many businesses, markets and local transportation remain crowded. Although inter-city travel is banned, tens of thousands are expected to leave the capital of Dhaka for their home villages to celebrate next week’s Muslim holiday of Eid al-Fitr.
“If we fail to maintain safety procedures across the country, the virus will make its natural progression, that’s for sure,” he said.

Bangladesh detects first case of Indian Coronavirus strain
A confirmed case of Indian Coronavirus strain has been detected in Bangladesh, says the Institute of Epidemiology, Disease Control and Research(IEDCR).
"The Indian variant of Coronavirus was detected in a sample test at Evercare Hospital in Dhaka. It has been published on Global Initiative on Sharing All Influenza Data(GSID)," said chief scientific officer of IEDCR ASM Alamgir.
Directorate General of Health Services (DGHS) DG Dr ABM Khurshid Alam also told the media that the Indian variant of Coronavirus has been found in Bangladesh.
The infected patients returned from India. They had been there for treatment, and now they’re staying in Jeshore,” he added.
Professor Nasima Sultana, additional director general of the institution, also confirmed the development at a press conference in the afternoon.
She said, “Jessore University of Science and Technology and IEDCR conducted separate examinations on the samples of 8 persons in Jessore. The Indian variant was found in 2 of them by both the institutions.”
Also read: Border with India to remain shut for another 14 days
“ Besides, 4 other samples tested there were found very similar to that of the Indian strain,” she added.
Besides, the DGHS said 60 of India returnees, who are now there in institutional quarantine, came here after getting infected there. But it is not sure yet whether they were infected with the Indian variant, it said. The Genome Centre of Jessore University of Science and Technology also confirmed the findings through a press release today.
According to the press release, three among 16 Indian returnees tested positive for Covid-19 recently after entering Bangladesh.
Their samples were collected from Jessore General Hospital and sent to the university lab on May 6.
A research team, led by the Assistant Director of the Genome Centre Dr Md Iqbal Kabir identified the Indian Covid variant in two of the collected samples through sequencing.
Earlier, on May 3, the DGHS said the government would be confirmed within a few days whether the highly contagious Indian variant of coronavirus has already reached Bangladesh as an investigation was on in this regard.

Speaking at a virtual press briefing, DGHS spokesperson Dr Nazmul Islam, said, "We may be able to say it in a few days whether the Indian strain of Covid-19 has come to Bangladesh or not."
He said the samples of those who tested positive for coronavirus after entering Bangladesh from India are being collected.
“These samples are being sent for genome sequencing…we’ll share it with you immediately after receiving the report.”
India is experiencing a horrific Covid situation as its crematoriums and burial grounds are being overwhelmed by the devastating new surge of infections tearing through the populous country with terrifying speed, depleting the supply of life-saving oxygen to critical levels and leaving patients to die while waiting in line to see doctors, reports AP from New Delhi.
India recorded over 4 lakh new Covid-19 cases in the last 24 hours ending 8 am Saturday, taking the country’s total caseload to over 2.18 crore. Out of these, over 37 lakh cases are currently active while over 1.79 crore people have recovered.
With 4,187 new deaths, the toll now stands at over 2.38 lakh. At least 14 states are reporting cases in five figures.

Maharashtra reported about 54,000 cases, Karnataka had nearly 49,000, while Kerala had over 38,000.
On April 26, Bangladesh closed its border with India for any kind of movement except that of cargoes for the next 14 day to prevent the spread of the deadly Coronavirus.
The Indian variant of Covid-19 viruses mutate all the time, producing different versions of themselves. Most of these mutations are insignificant - and some may even make the virus less dangerous - but others can make it more contagious and harder to vaccinate against.
The original India variant - officially known as B.1.617 - was first detected in October, reports the BBC.
That version has now been re-characterised as three different subtypes, all with slightly different genetic mutations.
India has said a new variant of the coronavirus first discovered there in March may be linked to a deadly second wave, according to another BBC report.
Samples containing the "double mutant"- or B.1.617 variant - have been found in several states with high case numbers.
An official at the National Centre for Disease Control said, however, that they had still been unable to fully establish a correlation.
A double mutant is when two mutations come together in the same virus.
