One Saturday, two Sunday, and one more Monday.

It’s not a lot of new cases by other counties’ standards, but four new cases of COVID-19 in three days is a major jump for Warren County.

Going into the weekend, there had been 15 cases — nine confirmed and six probable — in the county since March.

As of Monday’s daily report from the Pennsylvania Department of Health, there were 19 cases — 13 confirmed and six probable.

That’s an increase of more than 26 percent.

“Unfortunately, as reported by the Pennsylvania Department of Health, there continues to be an increase in COVID cases across Pennsylvania, including in Warren County,” Warren County Emergency Management Public Information Officer Cecile Stelter said. “It should be also noted that there is now a 76 percent recovery rate in the state.”

“Some factors that could be contributing to higher reporting of cases include: the counting of confirmed, probable, presumptive positives and antibody positives as ‘new positives’; the week or more timeframe from testing to results; and the overall increase in COVID testing across the state,” Stelter said. “As we mentioned before, we are in the summer season, which translates to an increase in travel and vacations. As more people are moving around Pennsylvania and in/out of higher COVID areas, including to/from other states, it is not unreasonable to expect a rise in cases.”

Four new cases in three days is not a good sign, but neighboring Erie County has had more new cases in one day than Warren County has had in five months.

“Warren County has still one of the lowest numbers of total positive cases within the state,” Stelter said. “Factors contributing to the low numbers are that county residents are wearing masks, social distancing and regularly washing their hands and using hand sanitizer.”

“Individuals are encouraged to continue these practices so that we can keep our numbers as low as possible here in Warren County,” she said. “Everyone’s cooperation is appreciated.”

Warren County has 48.10 cases per 100,000 residents — still easily the lowest in the state. The next lowest rates are in McKean County — where it is 80.6 cases per 100,000 people and in Tioga County which has 85.9 of 100,000.
