Infusion treatment helps those with mild COVID-19 symptoms The Courier Memorial Medical Center SPRINGFIELD – Tim Yarnik, his wife and daughter were on their way to an outing in St. Louis and planned to visit his dad, who lives in Staunton, on the way there. His dad, Art, who’s 87 years old and lives alone, wasn’t acting himself, and his forehead felt warm. They urged him to be tested for COVID-19. Two days later, he tested positive for the virus. His fever was 103 degrees. “We were frightened for him,” Yarnik said. Tim Yarnik reached out to a friend, who told him about a new therapy that helped COVID-19 patients. When he called Memorial Health System’s respiratory clinic, the staff told him they had a 5 p.m. opening that day and stressed the importance of not waiting another day. Yarnik’s brother-in-law drove his dad to Springfield.
