The United States has the highest recorded death toll in the world from Covid-19, with over 194,000 deaths.
What is the situation elsewhere?
Countries across Europe are seeing an increasing number of cases daily amid fears of a resurgence of the virus.
Local blockades were imposed in the worst affected regions and calls were renewed for people to wear face covers and follow the rules of social distancing.
Other countries that have seen a resurgence of the virus include Peru, Israel, South Korea, and Australia.
On Sunday, the Australian state of Victoria police arrested more than 70 protesters for breaking orders to stay home. About 250 people had participated in the protest in the city of Melbourne, which was sponsored by social media groups that shared the pandemic conspiracy theories.
Victoria was the epicenter of the Australian epidemic, accounting for 75% of cases and 90% of deaths.
Israel, meanwhile, will impose a new nationwide blockade as coronavirus cases continue to rise. Harsh restrictions will go into effect on Friday – Jewish New Year – and will last at least three weeks, authorities said.
Israel has seen more than 153,000 confirmed infections and 1,108 deaths from Covid-19, according to a Johns Hopkins University tally.
