A pandemic of the novel coronavirus has now killed more than 1.3 million people worldwide.
Over 58.7 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 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. The criteria for diagnosis -- through clinical means or a lab test -- has also varied from country to country.
The United States is the worst-affected nation, with more than 12.2 million diagnosed cases and at least 256,783 deaths.
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.

"We're seeing exponential growth in cases," CDC COVID-19 incident manager Dr. Henry Walke said. "The opportunity to translocate disease or infection from one part of the country to another leads to our recommendation to avoid travel at this time."

Los Angeles may see another stay-at-home order
With the pandemic intensifying in Los Angeles County, another stay-at-home order is possible in "the near future," said Christina Ghaly, the county's health department director, "if we can't get the numbers down."
"Earlier on in the pandemic, we were seeing the cases among people who had known risk factors: they were in congregate living facilities, skilled nursing facilities, they had a clear exposure in their workplace," she told "GMA3: What You Need To Know." "Now, the transmission is just simply much more widespread. And it seems to be due to the fact that people are mingling with others outside of their household, maybe are letting their guard down with their mask or not wearing the mask, and just not always following those basic public health practices."

With Thanksgiving one week away, Ghaly warned, "A test can't be used as a free pass for getting into a social gathering with people outside of your household."
"The test result is really only accurate on the day you took the test," she explained. "When it comes back a day later, you could have turned to be positive that day, or certainly the day after that or the day after that. So while the test is helpful and very critical part of helping us to curb the transmission of COVID when combined with other measures, by itself, it doesn't necessarily do anything. So I would encourage people, please don't use a test to go out with your friends on the weekend or to engage and intermingle with people that are outside of your household. "

Locksley, who tested positive Wednesday and is isolating at home, said in a statement, "I am feeling strong, with only minor symptoms."
"I will continue to lead this program virtually and our game preparations for Indiana [set for Nov. 28] will begin immediately," he said. "This virus is testing our players and coaches right now, but I have no doubt that we will emerge as a stronger unit for having gone through this together."

Fauci says his frustration 'borders on pain': 'This is a public health crisis'
With over 11.5 million cases and more than 250,000 deaths in the U.S., the "flu doesn't even come close," Dr. Anthony Fauci told the USA Today editorial board.
Fauci said his "frustration" with those not taking the pandemic seriously "borders on pain."

"Either people don't want to look at the data or they look at the data and they say it's fake. No, it isn't fake," Fauci said. "This is a global issue. I tell the people who deny or think that this is nothing, do you mean that every single country in Europe is doing the same thing, is making things up? They're not."

"Get rid of these ridiculous conspiracy theories and realize this is a public health crisis," Fauci said. We don't want to shut down as a nation because of the psychological and economic consequences of that. But we at least have got to be consistent in doing some fundamental things, so that's what concerns me. We're in a vulnerable position."
