(NEW YORK) — A pandemic of the novel coronavirus has now killed more than 1.3 million people worldwide.

Over 55 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.

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 nation, with more than 11.2 million diagnosed cases and at least 247,220 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.

Here’s how the news is developing Tuesday. All times Eastern:

Russia registers 442 new deaths in all-time high

Russia registered 442 deaths from COVID-19 in the last 24 hours, marking the country’s highest single-day death toll from the disease since the pandemic began.

An additional 22,410 new cases of COVID-19 were also confirmed nationwide over the past day. Russia’s cumulative total now stands at 1,971,013 cases with 33,931 deaths, according to the country’s coronavirus response headquarters.

Moscow remains the epicenter of the country’s outbreak and recent surge. More than a quarter of the newly confirmed cases — 5,882 — and nearly 17% of the new deaths — 74 — were reported in the capital, according to Russia’s coronavirus response headquarters.

Despite the growing number of infections and deaths, Russian authorities have repeatedly said they have no plans to impose another nationwide lockdown.

The Eastern European country of 145 million people has the fifth-highest tally of COVID-19 cases in the world, behind only the United States, India, Brazil and France, according to a real-time count kept by Johns Hopkins University.

US reports over 166K new cases

There were 166,045 new cases of COVID-19 confirmed in the United States on Monday, according to a real-time count kept by Johns Hopkins University.

It’s the fourth day in a row that the country has reported over 150,000 newly diagnosed infections. Monday’s count is slightly less than the all-time high of 177,224 on Nov. 13.

An additional 995 fatalities from COVID-19 were also registered nationwide on Monday, down from a peak of 2,609 new deaths on April 15.

A total of 11,205,486 people in the United States have been diagnosed with COVID-19 since the pandemic began, and at least 247,220 of them have died, according to Johns Hopkins. The cases include people from all 50 U.S. states, Washington, D.C. and other U.S. territories as well as repatriated citizens.

Much of the country was under lockdown by the end of March as the first wave of pandemic hit. By May 20, all U.S. states had begun lifting stay-at-home orders and other restrictions put in place to curb the spread of the novel coronavirus. The day-to-day increase in the country’s cases then hovered around 20,000 for a couple of weeks before shooting back up and crossing 100,000 for the first time on Nov. 4.
