Butler County saw 21 new confirmed cases of COVID-19 Thursday, while 30 new deaths and more than 2,000 new cases were reported statewide.

The Pennsylvania Department of Health said the 2,063 new cases are one of the highest daily increases since the pandemic began, but a data error led to cases, which should have been reported Wednesday, not being reported until Thursday.

A faulty data file sent to the reporting system by a laboratory earlier this week prevented some of the lab results from being properly reported, the department said.

The department reported the county had 1,273 confirmed cases, 231 probable cases and 26,025 negative tests. The number of deaths remained 27.

On Wednesday, the U.S. Centers for Disease Control and Prevention updated its definition of close contact.

Until now, the CDC said close contact was spending 15 minutes within 6 feet of someone who tested positive.

Close contact is now a total of 15 minutes or more, including shorter, but repeated contacts that add up to 15 minutes over a 24-hour period, according to the CDC.

The CDC continues to advise that anyone who has been in close contact with a COVID-19 patient should quarantine for two weeks.
