Arkoosh, who is the chairwoman of the county commissioner's board, announced Monday morning that she tested positive for the virus using an at-home test.
The physician attributes her mild symptoms to her J&J vaccine and Moderna booster.
"I'm so grateful to the scientists and researchers who made those shots possible and I encourage everyone to get vaccinated and boosted," she said in a statement.
"In the meantime, I'll be following CDC’s guidance and isolating at home."
The Democrat is vying for the open U.S. Senate seat currently held by Republican incumbent Sen. Pat Toomey, who is not running for reelection in 2022.
