Trump issues Brazil travel ban due to COVID-19
Nearly 100,000 have died in the United States from COVID-19.
A pandemic of the novel coronavirus has now killed more than 342,000 people worldwide.
More than 5.3 million people across the globe have been diagnosed with COVID-19, the disease caused by the new respiratory virus, according to data compiled by the Center for Systems Science and Engineering at Johns Hopkins University. The actual numbers are believed to be much higher due to testing shortages, many unreported cases and suspicions that some governments are hiding the scope of their nations' outbreaks.
The United States is the worst-affected country in the world, with more than 1.6 million diagnosed cases and at least 97,599 deaths.
