The global tally for confirmed cases of the coronavirus that causes COVID-19 climbed to 23.9 million on Wednesday, with the death toll rising to 819,945,according to data aggregated by Johns Hopkins University. At least 15.6 million people are confirmed to have recovered. The U.S. has by far the most cases at 5.8 million, and the most deaths at 178,524. There was alarm at the news that the Centers for Disease Control and Prevention has modified its testing guidelines and will now exclude people with no symptoms, even if they have been exposed to an infected patient. As many cases are people who are not showing symptoms, experts fear it will lead to less testing and less reliable data on spread. Brazil is second with 3.7 million cases and 116,580 deaths. India is third measured by cases at 3.2 million, followed by Russia with 968,297 and South Africa with 613,017. Mexico has 568,621 cases and 61,450 deaths, the third highest in the world. India now has 59,459 deaths, putting it ahead of The U.K. That country has 329,869 cases and 41,535 fatalities, the highest in Europe and fifth highest in the world. China, where the illness was first reported late last year, has 89,752 cases, and 4,712 fatalities
