The novel coronavirus pandemic has now killed more than 613,000 people worldwide.

Over 14.8 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 or downplaying the scope of their nations’ outbreaks.

The United States has become the worst-affected country, with more than 3.8 million diagnosed cases and at least 141,845 deaths.

7:48 p.m.: Los Angeles says most new cases are in people below age 41
Younger people are continuing to drive new COVID-19 infections in Los Angeles County, health department officials said.

The county reported 2,741 new cases of COVID-19 on Tuesday, of which 57% were people under age 41.

However an overwhelming majority of all deaths — nearly 75% — are in people over the age of 65, Director of Public Health Barbara Ferrer said. That age group accounts for 11% of all cases.

“The tragedy of what we are witnessing is that many of our younger residents are interacting with each other and not adhering to the recommended prevention measures, while our older residents continue to experience the results of this increased spread with the worst health outcomes, including death,” Ferrer said.

The county has 161,673 confirmed cases of COVID-19 and 4,154 deaths.

Statewide, California reported 400,769 total cases on Tuesday. That number will likely edge out New York’s statewide total — currently at 408,181 — on Wednesday.
