(NEW YORK) — A pandemic of the novel coronavirus has now killed more than 712,000 people worldwide.

More than 19.1 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 United States is the worst-affected country around the world, with more than 4.8 million diagnosed cases and at least 160,104 deaths.

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

5:20 a.m.: US weekly COVID-19 cases, deaths down

Another day, another grim milestone for the U.S. as the coronavirus pandemic continues across the globe. Overnight, the U.S. surpassed 160,000 deaths, bringing its total to at least 160,104 as of 4:30 a.m., according to Johns Hopkins. The U.S. crossed 150,000 deaths last week.

In good news, however, an internal Federal Emergency Management Agency memo obtained by ABC News shows that the U.S. is slightly coming down from its recent national surge. New cases and deaths in the last week have both decreased in week-over-week comparisons. At least 396,559 new cases were confirmed during the period of July 29 and Aug. 5, which is a 12.6% decrease from the previous seven-day period.

There were 7,348 deaths recorded in the same time frame, marking a 2.4% decrease in new deaths compared with the previous week.

The national test-positivity rate is also going down. In the last seven days, the rate was 7.5%, which is down from 8.6% from the previous week.

Only two states and territories, according to the FEMA memo, are in an upward trajectory of new cases, while eight are at a plateau and 46 states and territories are going down.
