Is pink eye a symptom of COVID-19?
A lot of people have been wondering this since noticing that Mike Pence’s left eye looked decidedly pink at the vice presidential debate Wednesday night, even though the vice president has said he tested negative for a coronavirus infection.
The short answer is: Pink eye can be caused by COVID-19, but only rarely.
The first thing to know is that conjunctivitis, commonly called pink eye, has many potential causes. The cause for any particular patient cannot be diagnosed properly without knowing the patient’s medical history or conducting an in-person ophthalmic examination, said Dr. Kathryn Colby, chair of the Department of Ophthalmology at NYU Langone Health.
Even the word “conjunctivitis” is a catchall that simply means there is redness and inflammation on the surface of the eye.
“It’s not a specific diagnosis,” Colby said. “It’s a description.”
Generally, this inflammation and redness is caused by either a bacterial or viral infection. Among the most common causes of the ailment are the same adenoviruses that can cause a common cold, she said.
