If you’ve been watching the Winter Olympic coverage you’ve probably noticed that Bob Costas has been having to wear glasses due to an eye infection in his left eye, which has now spread to his right eye. His infection has sparked quite a conversation on Twitter, and now Matt Lauer will take over for Costas, allowing him to rest his eyes.
Dr. Timothy Ehlen, Minneapolis Eye Center, was interviewed by KARE 11, an NBC new affiliate in Minneapolis, explaining the cause and treatment for Costas’ infection. Ehlen said that eye infections can be caused by bacterial or viral conjunctivitis, also known as pink eye. Ehlen said viral is the most common and contagious. “You can get it from touching things to being close to people from a mild cold that converts to conjunctivitis.
While bacterial conjunctivitis can be treated with antibiotics and generally goes away within a couple days, Ehlen said there’s no medication to treat viral. “Sometimes we can use certain drops to kind of control the symptoms, but the virus itself takes anywhere from a week to 14 days to clear, and that’s per eye.”
