A pandemic of the novel coronavirus has now killed more than 1 million people worldwide.
Over 36 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 criteria for diagnosis -- through clinical means or a lab test -- has varied from country-to-country. Still, the actual numbers are believed to be much higher due to testing shortages, many unreported cases and suspicions that some national governments are hiding or downplaying the scope of their outbreaks.
Since the first cases were detected in China in December, the virus has rapidly spread to every continent except Antarctica.
The United States is the worst-affected country, with more than 7.5 million diagnosed cases and at least 211,725 deaths.
California has the most cases of any U.S. state, with more than 841,000 people diagnosed, according to Johns Hopkins data. California is followed by Texas and Florida, with over 803,000 cases and over 722,000 cases, respectively.
More than 190 vaccine candidates for COVID-19 are being tracked by the World Health Organization, at least seven of which are in crucial phase three trials.

Fauci warns US could have 300-400k COVID-19 deaths
Between 300,000 and 400,000 people could die from COVID-19 in the United States, according to the nation's top expert on the coronavirus pandemic.
Dr. Anthony Fauci, the director of the National Institute of Allergy and Infectious Diseases and a key member of the White House coronavirus task force, offered the grim prediction while speaking at a virtual event hosted by American University on Tuesday.

"The models tell us that if we do not do the kinds of things that we're talking about in the cold of the fall and the winter, we could have from 300,000 to 400,000 deaths," Fauci said. "That would be just so tragic if that happens."
More than 210,000 people across the nation have died from the disease so far.

The Czech Republic now has the highest rate of COVID-19 infection in Europe. Over the past two weeks, the country of 10.7 million people has reported 346.1 cases per 100,000, surpassing Spain for the first time, which has seen 305 cases per 100,000, according to data published Tuesday by the European Center for Disease Prevention and Control.
Earlier this week, the Czech government declared another state of emergency due to the rapid increase in infections, with strident restrictions ranging from limitations on public gatherings to closures for some schools. Officials had relaxed almost all coronavirus-related restrictions over the summer.
The Czech Republic is among a handful of European countries, including France, Spain and the United Kingdom, that are grappling with an uptick in COVID-19 cases as a second wave of infections hits the region.
