A pandemic of the novel coronavirus has now killed more than 980,000 people worldwide.
Over 32 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 6.9 million diagnosed cases and at least 202,728 deaths.
California has the most cases of any U.S. state, with more than 799,000 people diagnosed, according to Johns Hopkins data. California is followed by Texas and Florida, with over 746,000 cases and over 693,000 cases, respectively.
Nearly 170 vaccine candidates for COVID-19 are being tracked by the World Health Organization, at least six of which are in crucial phase three trials.

Boulder bans gatherings for 18 to 22 year olds
In Boulder, Colorado, people ages 18 to 22 will soon be banned from all gatherings, whether indoors, outdoors, or with people outside that age range, the Boulder County Public Health Department announced.
This comes after nearly three weeks of cases rising in Boulder County, "with the vast majority" connected to 18 to 22 year olds, "particularly those attending the University of Colorado Boulder," the department said.
"While there has been little evidence of spread of the virus beyond the 18-22 age group, the continued increase in new cases in the city of Boulder prompted the Public Health Order to help prevent the spread to other community members," the department said.
The health department also calls out 36 addresses where the department claims residents "repeatedly engaged in activities that violate public health orders." Those residents must stay in their homes for two weeks, only leaving for essential services, according to the Health Department.
The order will last for two weeks, beginning at 4 p.m. local time on Thursday.
Residents in the 18 to 22 age group are exempt for exercising outside alone, studying outside alone and going to work if they don’t live in one of the homes with stay-at-home requirements.
Young adults can interact with relatives they live with, and those in high school can participate in school activities, the department added.

"The app will advise you to self-isolate if you have been in close contact with a confirmed case," the Department of Health and Social Care said. "It will also enable you to check symptoms, book a free test if needed and get your test results."
