A pandemic of the novel coronavirus has now killed more than 1.1 million people worldwide.

Over 41.5 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 8.4 million diagnosed cases and at least 223,000 deaths.

California has the most cases of any U.S. state, with more than 893,000 people diagnosed, according to Johns Hopkins data. California is followed by Texas and Florida, with over 871,000 cases and over 768,000 cases, respectively.

Nearly 200 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.

Fauci suggests kids trick-or-treat by saying hello to neighbors

Dr. Anthony Fauci is suggesting a new twist on trick-or-treating during the pandemic.

Fauci, director of the National Institute of Allergy and Infectious Diseases, recommends kids in costume go to a neighbors home, knock on the door and stay six or more feet away.

"Wear a mask, say hello," Fauci said in a livestream interview last week with Chrisi Grimm, the principal deputy inspector general for Health and Human Services.

But when it comes to the question of accepting candy, Fauci may disappoint the kids of America.

"The question of taking things like candy and stuff. You know, to me, it would be just. ‘Hello, I'm giving you a virtual trick-or-treat,' as opposed to getting involved in people that you don't know,” he said.

Former Vice President Joe Biden, the Democratic nominee for the upcoming presidential election, has tested negative for COVID-19 ahead of Thursday's final debate in Nashville, according to his campaign.

Biden has tested negative for the disease 13 times since his campaign began releasing the results of every test, following the last presidential debate in Cleveland on Sept. 29.

President Donald Trump tested positive for COVID-19 earlier this month, two days after debating Biden in Cleveland.

US weekly unemployment filings dip to 787,000

The U.S. Department of Labor said Thursday that weekly unemployment filings have dipped below the 800,000 mark for the first time in months, falling to 787,000 last week.

It's the lowest number of weekly jobless claims since March, when the coronavirus pandemic clobbered the U.S. labor market and the tally of initial unemployment filings peaked at some 6.9 million in a single week.

While the drop is a welcome sign for an economy still entrenched in a pandemic-induced financial crisis, the figure still remains well above pre-pandemic levels. It also dwarfs the previous record for initial claims set in 1982.

An additional 30 deaths from COVID-19 were also registered Wednesday. The cumulative totals now stands at 392,049 cases and 9,905 deaths, according to the latest data from the country’s public health institute.

Germany has broken its own record for daily case counts several times this month. While testing has increased since then, the country is among several in Europe that have seen a sharp uptick in COVID-19 infections in recent weeks.
