OKLAHOMA CITY (AP) — Oklahoma Gov. Kevin Stitt, the first governor in the nation to test positive for the coronavirus, said Tuesday that he has donated plasma to help other virus patients recover.

Stitt made the donation recently at an Oklahoma Blood Institute center in Enid, the Republican governor said in a statement.

He says “donating convalescent plasma is the easiest way Oklahomans who have recovered from COVID-19 can help their friends and neighbors.”

Convalescent plasma is being researched as a potential treatment or preventive measure for the virus that as of Tuesday had infected a reported 44,728 people in Oklahoma and left 618 dead. The true number of cases in Oklahoma is likely higher because many people have not been tested, and studies suggest people can be infected y $1.50. and Home not feel Delivery sick. $8.50/mo. i month outside Kay County,
