Pennsylvania reported 492 new confirmed COVID-19 cases and eight deaths Monday and 505 cases and three deaths Sunday, slight drops that come as concerns about rising infections nationally has officials scrutinizing the numbers to look for trends.

The state Health Department's figures from Friday and Saturday were around 600 new confirmed cases and 22 and 24 deaths, respectively.

Pennsylvania has so far had nearly 86,000 confirmed infections and 6,614 deaths.

Locally, Butler County saw an increase of 18 confirmed cases over the weekend, going from 252 on Friday to 270 as of Monday.

Butler Health System also reported Monday that six patients were being treated at Butler Memorial Hospital, a slight drop from the eight patients reportedly being treated heading into the weekend Friday. Of the six, four are suspected cases of COVID-19, while the other two are confirmed cases with one listed in the ICU.

Officials with the regional health system also announced Monday that the BHS Laboratory is now able to offer the COVID-19 antibody test in-house.

According to the Centers for Disease Control and Prevention website, antibody tests check a patient's blood by looking for antibodies, which might indicate if an individual had a past infection with the virus that causes COVID-19.

Dr. John Love, medical director of infectious disease at Butler Health System, said BHS has been using the antibody tests already. However, he explained the detection method was used sparingly due to the hospital needing to send the test to an outside lab for results. Now, those tests can be processed in-house.

“If you're symptomatic and you need to get a swab, then you're going to be swabbed,” Love said. “All of us in medicine are trying to figure out this disease.”

Love said the antibody test would be used in instances in which a person had been exposed to COVID-19, and even experienced some symptoms, but had not been immediately tested. He urged people to talk to their providers about antibody testing.

Moreover, Love warned that people need to remain vigilant in terms of COVID-19 as the state moves into the “green” phase. He stressed that just because a person tests positive for COVID-19 antibodies doesn't mean they are immune to the disease.

He stressed that people need to continue to wear a mask, wash their hands, social distance and follow all the guidelines set forth by the CDC.

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.

The final two counties in the state, Philadelphia and Lebanon, will be moved to the least restrictive “green” zone in Gov. Tom Wolf's color-coded reopening system Friday.

There has been particular focus on the disease's spread in Allegheny County, home to the city of Pittsburgh, where officials will stop on-site consumption of alcohol in bars and restaurants as of 5 p.m. Tuesday.

The move is in response to what they have described as an alarming increase in infections, largely among younger people.

Allegheny County is home to 1.2 million people and is the state's second most-populous county behind Philadelphia.
