Gov. Mike DeWine of Ohio has tested positive for the coronavirus, his office said in a statement on Thursday, making him the second governor in the nation known to have received a positive test result.
Mr. DeWine, a Republican who has stood out in his party and among the nation’s governors for his decisive response to the virus, was tested as part of a standard protocol because he was scheduled to greet President Trump on the tarmac of Burke Lakefront Airport in Cleveland on Thursday.
Mr. DeWine did not meet with the president, who is expected to speak about the economy and visit a Whirlpool factory during a visit to Ohio on Thursday afternoon.
Mr. DeWine was not experiencing symptoms, his office said, and he was returning to Columbus, where he will be tested again. He plans to quarantine in his home for the next 14 days.
The positive test result comes after months of warnings from Mr. DeWine, who was the first governor in the country to shut down schools in March. He also issued an early stay-at-home order and intensified his message as cases rose in Ohio through June and July.
In a televised address in mid-July, he warned Ohioans that “the enemy is here.” As recently as this week, he shared a series of examples of how the virus was spreading at church services, weddings, and other family gatherings and urged residents to stay home.
“Just because it’s your family, just because it’s your friends, they could still be carrying the virus,” Mr. DeWine said.
Mr. DeWine is the second governor in the nation known to have tested positive for the virus. Gov. Kevin Stitt of Oklahoma, a Republican, received a positive test result last month.
