A pandemic of the novel coronavirus has now killed more than 1 million people worldwide.
Over 37.6 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 7.7 million diagnosed cases and at least 214,771 deaths.
California has the most cases of any U.S. state, with more than 855,000 people diagnosed, according to Johns Hopkins data. California is followed by Texas and Florida, with over 818,000 cases and over 736,000 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.

HHS whistleblower says public should not trust White House on COVID-19
Whistleblower Rick Bright, the federal vaccine expert who was ousted from the U.S. Department of Health and Human Services after he lodged a complaint against the Trump Administration earlier this year, said that the public should not trust the White House when it comes to information about the coronavirus, during an interview with ABC's The View on Monday.

"We need to hear directly from the scientists at the CDC, at the FDA and at the NIH," Bright said. "Public health guidelines have been disparaged and ignored," he added, referring to the White House.
"This is why we have 215,000 dead Americans today. This is why we have up to 50,000 new infections today. This is why we're going to have terrible winter if we don't do something now to turn around the rhetoric, tell people the truth."

Analysis shows cases rising in 32 states plus DC
An ABC News analysis of COVID-19 trends across all 50 U.S. states as well as Washington, D.C. and Puerto Rico found there were increases in newly confirmed cases over the past two weeks in 32 states as well as the nation's capital.
The analysis also found increases in the daily positivity rate of COVID-19 tests in 22 states plus D.C., increases in COVID-19 hospitalizations in 35 states and increases in daily COVID-19 death tolls in 13 states plus Puerto Rico.
The seven-day average of new cases in the United States is the highest it has been since Aug. 17.
Last week, 14 states reported their greatest single-day increases in the number of new COVID-19 cases, while 14 states hit a record number of current COVID-19 hospitalizations and two states recorded their highest single-day death tolls from the disease.
The trends were all analyzed from data collected and published by the COVID Tracking Project over the past two weeks, using the linear regression trend line of the seven-day moving average.

UK prime minister outlines 3-tier lockdown system for England
The Liverpool area will be placed on the highest tier of England's new COVID-19 alert system from Wednesday, with bars, pubs and gyms forced to close, British Prime Minister Boris Johnson announced.
Johnson outlined the country's new three-tier system of COVID-19 alert levels on Monday afternoon, while addressing lawmakers in the House of Commons. He said every area of England will be placed into one of the three tiers -- "medium," "high" and "very high."
The "medium" level, which the prime minister said will cover most of the country, will consist of national measures, including the "rule of six" -- a ban on any gathering of more than six people -- and a 10 p.m. curfew for hospitality venues.
The "high" level, Johnson said, will prevent all social mixing indoors between different households or support bubbles in an effort to reduce household-to-household transmission, with the "rule of six" still in effect for mixing outdoors.
"Most areas which are already subject to local restrictions will automatically move into the 'high' alert level," the prime minister told lawmakers.
The "very high" level will ban social mixing indoors and in private gardens, along with the closure of all bars, pubs, gyms, betting shops, casinos and leisure centers in these areas, according to Johnson. The Liverpool City Region, home to 1.5 million people, is the first area to enter the "very high" alert level.
"The 'very high' alert level will apply where transmission rates are rising most rapidly," Johnson said.
All retail outlets, schools and universities will remain open across England.
"This is not how we want to live our lives," the prime minister told lawmakers. "But this is the narrow path we have to tread between the social and economic trauma of a full lockdown and the massive human and indeed economic cost of an uncontained epidemic."
The new measures come as England saw its number of COVID-19 infections quadruple in the last three weeks. There are now more patients hospitalized with COVID-19 than when the country went into lockdown in late March, according to Johnson.
"I must warn the House, the weeks and months ahead will continue to be difficult and will test the mettle of this country," he said. "I have no doubt at all that together we will succeed."

Czech Republic introduces more restrictions after record surge
The Czech Republic has imposed more restrictive measures aimed at curbing the spread of COVID-19, as the country combats the highest rate of infection in Europe.
Cinemas, gyms, indoor public swimming pools, theaters and zoos will all be shuttered for at least two weeks. Bars and restaurants are ordered to close by 8 p.m. and no more than four patrons are allowed at a table. All universities and most high schools will offer only remote classes.
The new measures announced by the Czech government come as the European country of 10.7 million hit a new peak of 8,618 confirmed cases on Friday, up more than 3,000 from the previous day. The cumulative total stands at 117,110 confirmed cases with 987 deaths, according to the latest data from the Czech health ministry.
The Czech government declared a second state of emergency on Oct. 5 due to the rapid increase in COVID-19 infections, after having relaxed almost all restrictions over the summer. The declaration will last for 30 days.
Czech Prime Minister Andrej Babis said on Friday that he cannot rule out a nationwide lockdown.
