HARRISBURG, Pa. (AP) — Thirty-eight more Pennsylvania deaths have been attributed to COVID-19, the state health department said Tuesday. This latest announcement brings the statewide death toll to 6,464.

Among those deaths, 4,410 were residents or nursing homes or personal care facilities.

Officials said another 510 positive cases of COVID-19 have been diagnosed, for a total of more than 82,000 during the past three-plus months.

The number of infections is thought to be far higher than the state’s confirmed case count because many people have not been tested, and studies suggest people can be infected without feeling sick.

For most people, the virus causes mild or moderate symptoms that clear up in a couple of weeks. Older adults and people with existing health problems are at higher risk of more severe illness, including pneumonia, or death.

Meanwhile, the Wolf administration said Tuesday that its most recent count shows about 518 contact tracers are in place to investigate and monitor the spread of infection.

Those tracers are following more than 4,000 contacts.

The Health Department said more than 2,700 cases were added to the investigation total during the week that ended Thursday.

The agency said it has been getting back nearly 14,000 test results per day over the past month.
