INDIANAPOLIS (AP) — Thirteen more people have died after contracting COVID-19, bringing the total number of statewide deaths to 343, health officials said Sunday.

The Indiana State Department of Health announced 508 additional cases, bringing the total number to 7,928 statewide.

Health officials say Marion County has the most new cases with 154. Several other counties had more than 10 new cases, including Allen, Elkhart and Hamilton.

For most people, the coronavirus causes mild or moderate symptoms, such as fever and cough that clear up in two to three weeks. For some, especially older adults and people with existing health problems, it can cause more severe illness, including pneumonia.

On Saturday, health officials said drive-through coronavirus testing sites are getting ready to open in four Indiana cities for medical workers, first responders and essential workers with symptoms of COVID-19. The free testing is scheduled to run Monday through Friday in Evansville and Sellersburg, in southern Indiana, and in Gary and Fort Wayne, in northern Indiana.
