(NEW YORK) — A pandemic of the novel coronavirus has now killed more than 552,000 people worldwide.

Over 12.2 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 governments are hiding the scope of their nations’ outbreaks.

The United States has become the worst-affected country, with more than 3.1 million diagnosed cases and at least 133,291 deaths.

5:13 a.m.: US COVID-19 deaths begin to climb again

National coronavirus case counts, hospitalizations and deaths continue to climb, according to the COVID Tracking Project. At least 867 people died of COVID-19 Thursday in the U.S.

Nationally, the seven-day average has begun to climb after an extended decline, the COVID Tracking Project said.

The last three days were the highest numbers the organization has reported since early June. This rise in deaths is concentrated in states with large outbreaks. Texas, California and Florida all reported their single highest day of deaths for the entire pandemic on Thursday.

This news comes as the Centers for Disease Control and Prevention updated its COVID-19 death toll forecast Thursday to say it expects between 140,000 to 160,000 deaths by Aug. 1

The CDC forecasts suggest that the number of new deaths over the next four weeks in Arizona, Alabama, Florida, Idaho, Montana, North Dakota, Nevada, Ohio, South Carolina, Tennessee, Texas, the U.S. Virgin Islands and West Virginia, will likely exceed the number reported over the last four weeks. For other states, the number of new deaths is expected to be similar to the number seen in the previous four weeks or to decrease slightly.
