Employees who come to the workplace after experiencing flu symptoms put their colleagues and employers at risk, said UTMB’s Dr. Trish Elliott, a physician of family medicine. One sick employee who decides not to stay home with the flu can spread the virus quickly. “As much as you want to be a team player, you are more of a team player if you stay home,” Elliott said. “It does become this domino effect when you get one person who comes in and it spreads like wildfire.”
