The second-term Democrat said a routine test on Tuesday detected the coronavirus.
“I have no symptoms and am feeling well,” Wolf said in a statement. “I am following CDC and Department of Health guidelines.”
Wolf’s spouse, Frances Wolf, has been tested but has not received the result, Wolf said. She is quarantining with him at their home in Mount Wolf, near York.
Wolf is one of several governors who have tested positive for the virus that causes COVID-19, including the governors of Oklahoma, Missouri, Virginia, Nevada and Colorado. President Donald Trump also contracted the virus.
Wolf, who is 72, said he continues to work remotely.
Wolf’s public schedule for the past week had just one event—a virtual news conference about the pandemic on Monday where he appeared along with his health secretary, Dr. Rachel Levine, and one of her deputies. All wore masks as they took turns at the podium.
His spokesperson, Lyndsay Kensinger, said others were tested at the same time, but she said federal health privacy rules prevented her from identifying them.
Nearly a month ago, the Wolf administration strengthened its mask mandate and required out-of-state travelers to test negative for the coronavirus before arrival. But infections, hospitalizations and deaths have continued to increase sharply in the state, prompting Wolf to reveal Monday that he is considering new mitigation measures.
Pennsylvania is averaging about 10,000 new confirmed cases per day, up more than 50 percent in two weeks, according to an AP analysis of data from The COVID Tracking Project. Hospitalizations have risen tenfold this fall. The state is averaging 140 deaths per day, up 64 percent since Nov. 24.
Wolf has repeatedly urged people to wear masks and to avoid congregating, and usually opens his broadcast news conferences by conspicuously using hand sanitizer.
“As this virus rages, my positive test is a reminder that no one is immune from COVID, that following all precautions as I have done is not a guarantee, but it is what we know to be vital to stopping the spread of the disease,” he said Wednesday.
Wolf is a former state revenue secretary and businessman who spent more than $10 million of his own money to win the Democratic gubernatorial primary nearly six years ago. He easily won reelection in 2018.
