DOYLESTOWN, Pa. (AP) — Pennsylvania has its first two cases of coronavirus, one in Delaware County and one in Wayne County, Gov. Tom Wolf announced Friday morning.

The two people are isolated in their homes, Wolf said at news conference in Harrisburg.

The Delaware County case is an adult who recently traveled to an area of the United States where COVID-19 is present, officials said. The other case is an adult who recently traveled to a country where the coronavirus is.

No other information on the people affected has been released.

Secretary of Health Dr. Rachel Levine said officials will be contacting those who have been in contact with the affected people and they will be quarantined.

“We expect more cases to be confirmed in the coming days and weeks,” Levine said.

Meanwhile, classes were cancelled Friday at five schools in a Bucks County school district because some members of its school community were exposed to a confirmed case of the new coronavirus, district officials said.

Levine says the two cases confirmed in Pennsylvania are not related to the case that closed schools.

Central Bucks School District Superintendent John Kopicki said the decision to close the schools was made “out of an abundance of caution" after consultations with state and local health officials.

The schools will be deep cleaned.

The U.S. death toll from the coronavirus climbed to 14, with all but one victim in Washington state, while the number of infections increased to over 200 across 18 states.

The coronavirus has infected around 100,000 people worldwide and killed over 3,400, the vast majority of them in China. Most cases have been mild, and more than half of those infected have recovered.
