INDIANAPOLIS (CBS/AP) — 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, health officials said Saturday as the state reported hundreds more confirmed cases of the disease and 30 new deaths.

The Indiana State Department of Health said the free testing for COVID-19 — the respiratory disease caused by the virus — is scheduled to run Monday through Friday in Evansville and Sellersburg, in southern Indiana, and in Gary and Fort Wayne, in northern Indiana.

Only medical workers, first responders and essential workers with symptoms of COVID-19 will be tested in the partnership between the state agency and local health officials. Those workers must present a driver’s license or other state-issued identification card and employment documentation.

“Tests will be conducted as long as supplies last and will be limited to one individual per vehicle,” the health department said in a news release.

A message seeking comment was left Saturday with the state agency asking whether there were plans to extend the drive-through testing effort beyond next week.

Gov. Eric Holcomb has defined the occupations of essential workers in his stay-at-home orders that now extend through at least April 20 for all but essential Indiana workers.

The health department said Saturday that 30 more Indiana residents had died from illnesses related to COVID-19, raising the state’s death toll to 330. Another 537 Hoosiers had confirmed cases of COVD-19, boosting the state’s total number since the outbreak started to 7,435.

The 30 deaths reported Saturday were fewer than the 55 announced Friday, which was the largest single-day figure, though health officials have noted that the deaths they report daily have occurred over multiple days.

Lake County continues to have the second highest number of confirmed cases with 676 following Marion County with 2,742. Lake County has seen 25 deaths while Marion County has reported 118.

Indiana’s state health commissioner announced Friday that 24 residents of a central Indiana nursing home hit hard by COVID-19 had died, up from the 11 deaths she had reported Monday for the Bethany Pointe Health Campus in Anderson.

Commissioner Dr. Kristina Box said 16 of the residents who died had tested positive for COVID-19 and the other eight had compatible symptoms. She said Friday that not all of the Bethany Pointe deaths had been included in the state’s daily death toll update.

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.
