A pandemic of the novel coronavirus has now killed more than 1 million people worldwide.

Over 38.4 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 7.9 million diagnosed cases and at least 216,639 deaths.

California has the most cases of any U.S. state, with more than 865,000 people diagnosed, according to Johns Hopkins data. California is followed by Texas and Florida, with over 830,000 cases and over 741,000 cases, respectively.

More than 190 vaccine candidates for COVID-19 are being tracked by the World Health Organization, at least 10 of which are in crucial phase three studies. Of those 10 potential vaccines in late-stage trials, there are currently five that will be available in the United States if approved.

US reports more than 52,000 new cases

There were 52,406 new cases of COVID-19 identified in the United States on Tuesday, according to a real-time count kept by Johns Hopkins University.

The latest daily tally is up by nearly 11,000 from the previous day but still falls under the country’s record set on July 16, when there were 77,255 new cases in a 24-hour-reporting period.

An additional 802 coronavirus-related fatalities were also recorded Tuesday, up by more than 400 from the previous day but down from a peak of 2,666 new fatalities reported on April 17.

A total of 7,858,344 people in the United States have been diagnosed with COVID-19 since the pandemic began, and at least 215,910 of them have died, according to Johns Hopkins. The cases include people from all 50 U.S. states, Washington, D.C. and other U.S. territories as well as repatriated citizens.

By May 20, all U.S. states had begun lifting stay-at-home orders and other restrictions put in place to curb the spread of the novel coronavirus. The day-to-day increase in the country's cases then hovered around 20,000 for a couple of weeks before shooting back up and crossing 70,000 for the first time in mid-July. The daily tally of new cases has gradually come down since then but has started to climb again in recent weeks.
