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

Over 40.7 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 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 8.2 million diagnosed cases and at least 220,955 deaths.

California has the most cases of any U.S. state, with more than 883,000 people diagnosed, according to Johns Hopkins data. California is followed by Texas and Florida, with over 862,000 cases and over 760,000 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.

Cuomo discourages New Yorkers from unnecessary travel to NJ, PA, CT

In New York, where the statewide positivity rate is 1.3%, neighboring states Connecticut, New Jersey and Pennsylvania now meet the criteria for New York's growing list of states on its travel advisory, Gov. Andrew Cuomo said Tuesday.

Because "there is no practical way to quarantine New York from Pennsylvania, New Jersey and Connecticut," the states won't be added to the list, Cuomo said in a statement. However, the governor said he's discouraging nonessential travel between the states.

These are the states and territories currently on New York's list: Alaska, Alabama, Arkansas, Arizona, Colorado, Delaware, Florida, Georgia, Guam, Iowa, Idaho, Illinois, Indiana, Kansas, Kentucky, Louisiana, Maryland, Michigan, Minnesota, Missouri, Mississippi, Montana, North Carolina, North Dakota, Nebraska, New Mexico, Nevada, Ohio, Oklahoma, Puerto Rico, Rhode Island, South Carolina, South Dakota, Tennessee, Texas, Utah, Virginia, Wisconsin, West Virginia and Wyoming.

Over 299,000 excess deaths in US this year, two-thirds attributed to COVID-19, says CDC

The official COVID-19 death toll in the U.S. "might underestimate the total impact of the pandemic on mortality," according to a new report from the CDC.

"Overall, an estimated 299,028 excess deaths have occurred in the United States from late January through October 3, 2020, with two thirds of these attributed to COVID-19," the CDC said.

Greece's daily increases may appear to be a fraction compared to its European Union neighbors, but the small Mediterranean nation was widely praised in the beginning of the outbreak for containing the spread through strict lockdowns.

Health Minister Vasilis Kikilias has acknowledged pressure is increasing, and according to local media, there's a fear that a surge in hospitalizations will quickly overwhelm health services.

Greece now has a total of 25,802 COVID-19 cases and at least 520 deaths, according to Johns Hopkins.
