Global Coronavirus Cases Increase By 1 Million In 4 Days

The number of reported coronavirus cases across the world surpassed 16 million Monday, a widely cited pandemic tracker revealed. Roughly 1 million global coronavirus cases were reported in the last 4 days alone.

Data compiled by the Johns Hopkins Coronavirus Research Center indicated that almost 16.3 million cases have been reported worldwide and nearly 650,000 people have reportedly died from the coronavirus. Experts believe that the numbers could actually be much higher due to testing shortages and underreporting, according to ABC News.
