People should be washing their hands for 20 seconds to protect themselves from the virus known as Covid-19. That's according to Public Health England,reports BBC.
The UK government is still working to contain the outbreak but the prime minister has warned that it's "highly likely" the UK will see further infection.

The number of people to have died from the coronavirus in Italy has shot up by 133 in a day to 366, officials say and reports BBC.
The total number of infections leapt 25% to 7,375 from 5,883, according to the Civil Protection agency.
The jump in figures comes as millions adapt to radical measures introduced on Sunday in an attempt to contain the outbreak.
Up to 16 million people in Lombardy and 14 provinces need special permission to travel under new quarantine rules.
Prime Minister Giuseppe Conte also announced the closure of schools, gyms, museums, nightclubs and other venues across the whole country.
The restrictions will last until 3 April.
The latest figures mean Italy now has the highest number of confirmed infections outside China, where the outbreak originated in December. It has overtaken South Korea, where the total number of cases is 7,313.
Italy has one of the world's oldest populations. The virus is particularly dangerous for the elderly and those with underlying health conditions.
Among the latest people to test positive in Italy is the army's chief of staff. Salvatore Farina said he felt well and was self-isolating.
The strict new quarantine measures affect a quarter of the Italian population and centre on the rich northern part of the country that powers its economy.
The health system is under immense strain in Lombardy, a northern region of 10 million people, where people are being treated in hospital corridors.
"We want to guarantee the health of our citizens. We understand that these measures will impose sacrifices, sometimes small and sometimes very big," Prime Minister Conte said as he announced the measures in the middle of Saturday night.
Under the new measures, people are not supposed to be able to enter or leave Lombardy, where Milan is the main city.
The same restrictions apply to 14 provinces: Modena, Parma, Piacenza, Reggio Emilia, Rimini, Pesaro and Urbino, Alessandria, Asti, Novara, Verbano Cusio Ossola, Vercelli, Padua, Treviso and Venice.
The UK Foreign Office advises against all but essential travel to these areas.
Some transport in and out of the regions affected continued on Sunday. Flights still arrived at Milan's Malpensa and Linate airports, though some scheduled flights were cancelled.
However, Italy's national carrier Alitalia said it would suspend all operations from Malpensa from Monday and Linate would only serve domestic routes. International flights would continue to and from Rome.
The World Health Organization (WHO) chief Tedros Adhanom Ghebreyesus praised Italy for making "genuine sacrifices" with the restrictions. Until Sunday only about 50,000 people in northern Italy had been affected by quarantines.
Last week the government announced the closure of all schools and universities across the country for 10 days.
What is the situation elsewhere?
The number of infections worldwide is more than 107,000, with about 3,600 deaths.
Most of the fatalities have been in China. But the country on Sunday reported its lowest number of new infections in a single day since January - an indication that the virus's spread there is slowing.
Iran, one of the worst hotspots outside China, has now confirmed 6,566 infections and 194 deaths.
However, the real figure is feared to be much higher. One report on Sunday, quoting a government envoy, said there had been 200 deaths in the northern Gilan province alone - but the figures were later removed.
In France, the virus is spreading among MPs. Two more members of the National Assembly have tested positive, officials said late on Sunday.
In total four deputies have been infected. Also on Sunday France reported 1,126 cases, a 19% increase in a day and the second largest number of infections in Europe after Italy.
The French government has banned gatherings of more than 1,000 people.

Women filled the streets of the world's largest cities Sunday to protest gender violence and inequality on International Women's Day, with the mothers of murdered girls leading a march in Mexico City and participants in Paris inveighing against the "virus of the patriarchy."
While many protests were peaceful celebrations others were marred by tension, with security forces arresting demonstrators at a rally in Kyrgyzstan and police reportedly using tear gas to break up a demonstration by thousands of women in Turkey.
"In many different ways or forms, women are being exploited and taken advantage of," Arlene Brosas, the representative of a Filipino advocacy group said during a rally that drew hundreds to the area near the Philippine presidential palace. Protesters called for higher pay and job security, and demanded that President Rodrigo Duterte respect women's rights.
Turkish riot police fired tear gas to disperse thousands of demonstrators who, in defiance of a government ban, tried to march along Istanbul's main pedestrian street to mark International Women's Day, media reports said.
Turkish authorities declared Istiklal street, near Istanbul's main Taksim square, off-limits, and said the planned march down the avenue was unauthorized. Thousands of demonstrators, most of them women, gathered near Istiklal regardless and tried to break through police barricades to reach it, according to the opposition Cumhuriyet newspaper and other media.
The independent T24 news website said police also fired blanks to disperse the crowd.
In Pakistan, however, women managed to rally in cities across the country, despite petitions filed in court seeking to stop them. The opposition was stirred in part by controversy over a slogan used in last year's march: "My Body, My Choice."
Some conservative groups had threatened to stop this year's marches by force. But Pakistani officials pledged to protect the marchers. The rallies are notable in a conservative country where women often do not feel safe in public places because of open harassment. The main Islamic political party, Jamaat-e-Islami, organized its own rallies to counter the march.
Tens of thousands of women filled the streets of Mexico's capital to protest rampant femicides and impunity for the killers. The country has recently seen a series of rowdy protests by women who have vandalized monuments and metro stations to express their anger in one of the world's most dangerous countries to be a woman.
On average, more than 10 women are slain each day in Mexico, often by their male partners.
The mothers of slain women and girls led Sunday's march, with people cheering them on, chanting: "You're not alone!" They were followed by homemakers, students and mothers with small children wearing purple shirts, bandannas and hats.
"I don't want to be the next one, and I don't want my mother to be the next one," said Ana Paula Santos, a 21-year-old public university student.
María de la Luz Estrada, coordinator of the National Citizen's Observatory on Femicide, said more Mexican women have taken to the streets in recent years because the assaults and killings are "increasingly more alarming."
Earlier, activists had painted the names of many of the thousands of women killed each year in Mexico on the ground of the capital's iconic Zocalo plaza.
One of the largest demonstrations occurred in Chile, where thousands flooded the streets of the capital with dancing, music and angry demands for gender equality and an end to violence against women.
"They kill us, they rape us and nobody does anything," some chanted.
National police estimated 125,000 took part in the capital and nearly 35,000 in other cities, but organizers said the crowds were far larger. Scattered clashes broke out at points when demonstrators threw rocks at police, who responded with water cannon.
Many protesters demanded that a proposed new constitution strengthen rights for women and thousands wore green scarves in a show of support for activists in neighboring Argentina, which is considering a proposal to legalize elective abortion.
Tens of thousands of women also marched through Paris, inveighing against the patriarchy.
"Enough impunity!" chanted some activists, who focused on France's unusually high rate of women killed by their husbands. Last year, one woman was killed every two or three days by a current or former partner, and the government is increasing efforts to crack down on domestic violence.
"They should provide resources for shelters for women, victims of violence, real resources, human resources, also prevention programs for violent men," union activist Julia Parbotin said.
Tens of thousands of women also marched in Madrid and other Spanish cities, despite concern over the spread of the new coronavirus.
A massive banner reading, "With rights, without barriers. Feminists without frontiers" in Spanish was carried at the front of the march in the capital.
Spanish health authorities did not put any restrictions on the march, but recommended that anyone with symptoms similar to those of the new coronavirus stay home. Authorities said 120,000 people participated in Madrid's march, down from 350,000 last year.
At a school in East London, meanwhile, the duchess of Sussex, Meghan Markle, joined students in listening to speeches about women labor activists, and urged both girls and boys to respect the contributions of women every day of the year.
"For young men ... you have your mothers, sisters, girlfriends, friends in your life — protect them. Make sure they are feeling valued and safe," she told the students.
But safety was in short supply at some events to mark the day.
The detonation of explosives triggered panic at a ceremony in Bamenda, an English-speaking town in the northwest of Cameroon. Suspicions focused on separatists who had vowed to disrupt the events. No one was killed or wounded.
Police in Bishek, the capital city of Kyrgyzstan, detained about 60 people after a group of unidentified men broke up what authorities called an unauthorized rally. About 10 women were released with charges of resisting police, the Akipress news agency reported, citing an attorney.
In Brazil, protests took a political turn, with many of the tens of thousands of protesters in Sao Paulo, Rio de Janeiro and Brasilia denouncing the administration of far-right President Jair Bolsonaro, who has made comments seen by many as offensive to women.
In Mexico, where activists plan to hold a "Day Without Women" on Monday, Natalia Olalde said she marched because she's fed up with the lack of justice for women in the country.
Government data shows that 3,825 women in Mexico met violent deaths last year, 7% more than in 2018. Authorities seem incapable of preventing or properly investigating the crimes, very few of which result in convictions.
The 18-year-old university student studying business administration worries she'll face sexual harassment once in the workforce.
"We want to be free and safe," said Olalde.
That's why she plans to join the women's strike as well on Monday. She vows to stay indoors, not even leaving for a coffee.
Two members of Congress, Sen. Ted Cruz and Rep. Paul Gosar, said Sunday they are isolating themselves after determining they had contact at a political conference with a man who has tested positive for coronavirus.
Cruz, R-Texas, said he had brief contact with the man at the Conservative Political Action Conference nearly two weeks ago and would spend the next few days at his home in Texas until a full 14 days had passed since their interaction.
Gosar, R-Ariz., said he had sustained contact with the man at CPAC and that he and three members of his senior staff were under self-quarantine. His office will be closed for the week, Gosar said in a tweet.
Besides Cruz and Gosar, the CPAC schedule listed three other senators and 12 House members who were scheduled to speak. They included No. 2 House GOP leader Steve Scalise of Louisiana, No. 3 Republican leader Liz Cheney of Wyoming and congressman Mark Meadows of North Carolina, who has since become the White House chief of staff.￼￼ Also on the schedule was Transportation Secretary Elaine Chao, the wife of Senate Majority Leader Mitch McConnell.
Both President Donald Trump and Vice President Mike Pence spoke at CPAC, but the White House said there was no indication that either had met or were in "close proximity" to the infected attendee.
Meanwhile, Maryland reported two new cases on Sunday, raising to five the total confirmed cases in the state. Virginia reported its second case.
In a separate case of coronavirus, a prominent Episcopal church in Washington, D.C., suspended all activities after announcing that one of its senior leaders was the first person in the nation's capital to test positive for the virus.
The Rev. Timothy Cole, the rector of Christ Church Georgetown, was in stable condition after being hospitalized Saturday night, according to a statement from the Rev. Crystal Hardin, the assistant rector.
In an unrelated case, Cruz said he met the man being treated for coronavirus 10 days ago at CPAC in suburban Oxon Hill, Maryland. The Texas Republican said he's not experiencing any symptoms, feels fine and has been advised by medical authorities that the odds of transmission were extremely low.
Yet, Cruz said, out of an abundance of caution he will remain at home in Texas for another few days until a full 14 days have passed since the interaction. He said medical authorities advised him that those who have interacted with him in the last 10 days should not be concerned about potential transmission.
David Popp, spokesman for Senate Majority Leader Mitch McConnell, R-Ky￼., said Sunday evening that no changes have been made in the chamber's schedule in the wake of Cruz's decision to remain in Texas. McConnell has spoken with Cruz, Popp said.
The Senate has a vote scheduled Monday evening and plans to be in session this week considering energy and possibly other legislation. The Senate and the House are set for a one-week recess the week of March 16.
According to Christ Church Georgetown website, Cole has been the rector since September 2016, is married and has two children.
``Out of an abundance of caution, Christ Church has canceled all activities including church services until further notice. We recommend that concerned community members contact their health care providers," the statement said.
Officials on Saturday had announced the district's first positive test, but identified the victim only as a man in his 50s. A second local positive test involves a man who visited the Washington area from Nigeria, but he was being hospitalized in Maryland, Mayor Muriel Bowser said.
Health officials said Sunday said they had determined as part of their investigation that "an individual's visitation to Christ Church Georgetown warrants precautionary measures" and they recommended a temporary halt to services. In response, the church publicly identified Cole as the victim.
The Washington mayor's office said a city high school is staying closed Monday, though no new confirmed coronavirus cases have been reported. Three people who stayed at the same house as the Nigerian man who tested positive in Maryland were tested Sunday and all were negative. But one of them works at School Without Walls High School, which is being kept closed to give staff time to communicate with staff and parents and to clean the school.
In Maryland, a Harford County resident in her 80s who contracted the virus while traveling overseas was hospitalized, officials said. A Montgomery County resident in his 60s who contracted the virus while traveling overseas was briefly hospitalized.
Virginia recorded its first case Saturday when a Marine stationed at Fort Belvoir and living at the Quantico base was found to have the virus. On Sunday, Virginia officials announced a second case involving a Fairfax man in his 80s who took a Nile River cruise.
Dr. Benjamin Schwartz, director of epidemiology and population health for the Fairfax County health department, said the Fairfax man developed systems of respiratory illness on Feb. 28 and was hospitalized on March 5. He remains hospitalized but is in stable condition and not in an intensive care unit, Schwartz said.
"Fortunately, the individual had limited contact with others while ill, and therefore the risk to the general Fairfax community remains low," said the county's health director, Dr. Gloria Addo-Ayensa.
Virginia state epidemiologist Dr. Lilian Peake said testing for the Fort Belvoir case was done at Walter Reed medical center, and testing for the Fairfax resident was done at a state lab in Richmond.
"The two cases are not related," Peake said. "At this point, there are no signs of the virus spreading in the community in Virginia."
Adriana. Dulce. Paola. Nayeli. Ingrid. Maria — lots of Marias. These are just some of the names of the thousands of women killed each year in Mexico, often by their intimate partners.
Tens of thousands of women wearing purple poured into the streets of Mexico City on Sunday to protest rampant and brutal gender violence in the country on International Women's Day.
Some spray painted messages like "Mexico kills women" onto monuments, smashed windows and set fires — often to cheers from the multitude. Most marched peacefully in groups organized by universities, non-profits or with friends.
Government data shows that 3,825 women in Mexico met violent deaths last year, 7% more than in 2018. That works out to an average of more than 10 women slain each day, making it one of the most dangerous countries in the world for females. Thousands more have gone missing without a trace in recent years.
Girls and women throughout the country will follow up with a strike on Monday.
"That means no going out, not even for a coffee," said Natalia Olalde, an 18-year-old university student who planned to observe the strike.
Murders of women in Mexico are often accompanied by sexual violence and stunning brutality. Some women are burned. Some are mutilated. Authorities seem incapable of preventing or properly investigating the crimes, very few of which result in convictions.
Protesters tinted red the water of the fountain to the Roman goddess Diana in Mexico City — to symbolize the blood of victims — and also the water of a fountain to the Roman goddess of wisdom, Minerva, in Guadalajara.
Activists then carpeted Mexico City's central Zocalo square with victims' names in white block letters. The names came from public records of deaths that appear to fall into the category of femicide, meaning those women's killings showed marks of hatred for the female gender.
"We decided it was a moment to put them into numbers — all those women who are missing, who they've taken from us," said Sofia De Robina, a lawyer with the Miguel Agustin Pro Human Rights Center.
The idea was to place names on the asphalt as a memorial, but also to give them a voice in the day's protest.
The protest amassed participation from across Mexican society, expanding well beyond the academics and activists that typically participate.
Housewives, students and even mothers with small children on their shoulders took to the streets of Mexico City wearing purple shirts, bandannas and hats. Purple is a color often used to represent gender equality.
They carried signs saying, "We are the heart of those that no longer beat" and "I'm marching today so that I don't die tomorrow."
María de la Luz Estrada, coordinator of the National Citizen's Observatory on Femicide, said more Mexican women have taken to the streets in recent years because the assaults and killings are "increasingly more alarming."
Estrada led a contingent of mothers whose daughters have been killed. Over time, the mothers have become activists who share their daughters' stories in the hopes that others can avoid the same tragic end. Several say officials initially ruled their daughters' deaths suicides, demonstrating little desire to investigate.
"Receiving the news that your daughter has been found without life is like being smashed against the wall," recounted Patricia Becerril, whose daughter Zyanya Estefanía was found dead in 2018 while studying to be a doctor in the central state of Puebla.
Seeing the mothers advance, the crowd of protesters chanted: "You're not alone!"
Ana Paula Santos raised her fist in the air as the mothers passed, while her eyes filled with tears.
"I don't want to be the next one, and I don't want my mother to be the next one," said the 21-year-old public university student.
Enriqueta Diego, a mother of two girls and a boy from the central city of Puebla, said she joined the march in the hopes of improving security for all the women in the country.
"They're killing us with total impunity," said the 52-year-old.
First-time protesters wrote names, contact phone numbers and even blood types on their arms as a security measure. Threats had circulated prior to the event that protesters might be attacked with acid.
Bands of masked women smashed windows, lit fires and spray painted messages. At least one onlooker suffered first degree burns after a fire bomb ricocheted into the crowd.
Afterward women taped their protest cards onto the fences around the country's Senate.
