PITTSBURGH (KDKA) - According to the CDC, multiple local counties now have a "substantial" level of COVID-19 transmission, which means it's recommended everyone regardless of vaccination status masks up indoors.

Allegheny, Butler, Lawerence, Beaver, Washington, Armstrong, Indiana, Clarion and Somerset counties all have "substantial" spread. Armstrong County had a "high" level of COVID-19 transmission, but it was moved back to "substantial."

According to the CDC, having a high COVID transmission level means for every 100,000 people, there are 100 cases. Substantial means there's 50 to 100 cases for every 100,000 people.

Armstrong County Public Safety Director Michael Mollick says not much has changed in the county recently regarding their COVID numbers, so he's not sure what to make of all this. Mollick says they keep a close eye on case numbers and are in constant communication with the state Health Department, which has not sounded any alarms so far.

"Looking at the stats they've given us over the last 14 days, we've only had about 20 new cases show up, which is about the average," said Mollick. "We've been running the last two to three months, so I'm not sure how the CDC came to that number."

The CDC recommends everyone, even those who are vaccinated, wear masks indoors in areas with "high" or "substantial" COVID-19 spread.

The state has said a statewide mask mandate is not in the works at this time. Instead, they're focusing their efforts on vaccination.
