Pennsylvania has confirmed 560 new coronavirus cases, raising the statewide total to 1,687.

The state Department of Health said 16 people in Pennsylvania have died due to the virus. The department released new numbers Thursday. Cases have now been confirmed in 48 of Pennsylvania’s 67 counties.

The confirmation of 560 new cases marks the biggest one-day jump by far. Before today, the largest one-day jump came Wednesday, with 276 new cases.

All of those who have tested positive are either in isolation at home or being treated at the hospital, the health department said.

There are 16,441 patients who have tested negative, the department said. The health department no longer issues estimates of the number of test results that are pending. Most testing is being done in private laboratories, the department said.

The health department doesn’t offer statistics on how many people recover from the coronavirus.

Most people do recover from the virus. Pennsylvania Department of Health spokesman Nate Wardle told PennLive the department is notified when someone with the coronavirus enters the hospital or tests positive while there. But the department doesn’t receive reports when a coronavirus patient is discharged.

The bulk of the cases have been concentrated in Philadelphia and its suburbs. There are 402 cases now in the city of Philadelphia alone, while neighboring Montgomery County has 282 cases.

But cases continue to rise across the state. Most counties in the Harrisburg area have confirmed cases. York and Lancaster counties each have 21 cases. Cumberland County has 15 cases, while Dauphin County has 13.

In western Pennsylvania, Allegheny County now has 133 cases.

Deaths due to the coronavirus have been reported in 10 counties, according to the health department: Allegheny (2); Butler (1); Delaware (1); Lackawanna (2); Lehigh (1); Luzerne (1); Monroe (2); Montgomery (2); Northampton (3); and Philadelphia (1).

Gov. Tom Wolf said at a press conference Wednesday that if the state can’t slow down the exponential growth of cases, “Our hospitals will soon be overwhelmed.”

Wolf has taken unprecedented steps to try to slow the spread of the virus. He has issued stay-at-home orders for 10 counties, including the Philadelphia and Pittsburgh areas. More than 6 million people - about half the state’s population - have been ordered to stay home except for essential trips.

“We’re trying to buy time to allow our health care system to ramp up,” Wolf said Wednesday.

Wolf has closed Pennsylvania schools until at least April 6 and possibly longer if necessary. He’s also ordered all businesses not considered “life-sustaining” to temporarily shut down to slow the spread of the virus.

Many workers are paying the price of the efforts to curb the pandemic. About 650,000 Pennsylvania residents have filed unemployment claims over the last 11 days. In the seven days through Saturday, Pennsylvanians filed about 379,000 claims, smashing the record for an entire week in the state.

Thousands of businesses have sought waivers to stay open. Some businesses and trade groups have said the state is impeding businesses that produce essential goods and supplies from operating.

Universities and colleges across the state have moved to remote learning for the rest of the spring semester.

Health Secretary Dr. Rachel Levine has continually urged residents to stay home to mitigate the spread of the virus. The first case was reported in Pennsylvania on March 6 and Levine has said the rapid spread of the virus is cause for serious concern.

Two of Pennsylvania’s neighboring states report far higher numbers.

New York has become the nation’s epicenter of the virus, with more than 30,000 confirmed cases and more than 300 deaths. New Jersey now has more than 4,400 cases, the second highest number in the nation, and 62 have died due to the virus in the Garden State.
