Pennsylvania's new cases of COVID-19 reached 601 on Monday, the state Health Department reported, and there three additional deaths were reported.
So far nearly 120,000 Pennsylvanians have been infected with the coronabirus, and 7,317 have died.
Officials say cases among younger people, notably those 19 to 24, have been increasing significantly. Cases among younger age groups have become more common than in those 50 and older.
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.
