Two new coronavirus cases were confirmed in southeastern Pennsylvania, Gov. Tom Wolf announced Saturday, bringing the state’s total to four cases.

The new patients live in Montgomery County and are self-isolating at home while showing “mild” symptoms, Wolf said. Both had traveled to areas of the United States where other COVID-19 cases have been confirmed.

“Even with these new cases, I want to reassure Pennsylvanians that the commonwealth is prepared and responding appropriately and swiftly so that information and resources are available,” Wolf said in a statement.

“I have been coordinating with legislative leaders from both parties, and we have agreed to immediately work toward a package that would provide resources to ensure we are aggressively mitigating the spread of COVID-19,” he added.

The state’s first two patients were reported Friday — one adult in Delaware County and another in Wayne County — and they are also isolating themselves at home, according to the governor’s office.

The two new patients in Montgomery County residents are adults and in stable condition, the Philadelphia Inquirer reported.

“When we know where they contracted a virus, we can reach out to everyone they were in contact with and start to stem the spread,” April Hutcheson, communications director for the state Department of Health, told the outlet.

There are more than 105,000 documented coronavirus cases and more than 3,500 related deaths reported across the world, including more than 400 cases in the United States.
