Coronavirus updates: CDC now 'strongly recommends' masks on airplanes, public transportation
The goal is to "help safely reopen America’s economy," the CDC said.
A pandemic of the novel coronavirus has now killed more than 1.1 million people worldwide.
Over 40 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 8.1 million diagnosed cases and at least 219,674 deaths.
California has the most cases of any U.S. state, with more than 875,000 people diagnosed, according to Johns Hopkins data. California is followed by Texas and Florida, with over 854,000 cases and over 755,000 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.

Ireland issues strict new lockdown measures
In an effort to stem rising coronavirus cases, Ireland will enter a six-week national lockdown starting Wednesday, according to the Irish government.

California board to independently review vaccine before distribution
California will only distribute COVID-19 vaccines after they've been independently approved by a state board, Gov. Gavin Newsom said during a Monday news conference.
The board will be made up of 11 experts from California universities and is meant to dispel vaccine hesitancy following the intense politicization already surrounding the potential vaccine.
Newsom also urged patience. "Don't expect that you'll go down to a local pharmacy anytime in this calendar year and get a vaccination," he said.
Instead, most Californians can expect to be vaccinated in 2021, according to the governor.

Russia reports nearly 16,000 new cases in new record high
Russia confirmed another 15,982 new cases of COVID-19 in the last 24 hours, its highest daily tally yet.
An additional 179 deaths from COVID-19 were also registered in the past 24 hours, down from last week's peak of 286. The cumulative totals now stand at 1,369,313 cases and 23,723 deaths, according to Russia's coronavirus response headquarters.
The country of 145 million people has the fourth-highest tally of COVID-19 cases in the world, behind only the United States, India and Brazil.
More than 33% of the newly confirmed cases -- 5,376 -- and over 28% of the newly registered deaths -- 51 -- were reported in the capital, Moscow, according to country's coronavirus response headquarters.
Although Russia has been breaking its own records for daily case counts and deaths almost every day since Oct. 9, authorities there are resisting shutting down businesses again. Few measures have been imposed in Moscow, the epicenter of the country's COVID-19 outbreak and recent surge.
