More than 81 million people worldwide have been infected by COVID-19 in one year, according to data compiled by the Johns Hopkins University (JHU).
The caseload reached 81,260,603 with 1,774,130 fatalities on Tuesday morning.
The US, which remained the worst-hit country in the world, has reported 19,300,726 cases.
Coronavirus is blamed for more than 330,000 deaths in the US. This has been the deadliest month of the outbreak in the US yet, with about 65,000 deaths in December so far, according to the COVID Tracking Project. The nation has repeatedly recorded more than 3,000 dead per day over the past few weeks, reports AP.
Besides, a huge US study of another COVID-19 vaccine candidate got underway Monday as states continue to roll out scarce supplies of the first shots to a nation anxiously awaiting relief from the catastrophic outbreak.
Public health experts say more options in addition to the two vaccines now being dispensed — one made by Pfizer and its German partner BioNTech, the other by Moderna — are critical to amassing enough shots for the country and the world.
