The new coronavirus behind the pandemic causes a respiratory illness called COVID-19. Its most common symptoms are a fever, coughing, and breathing problems. Rarely, it also can cause an eye infection called conjunctivitis.
Symptoms
Based on data so far, doctors believe that 1%-3% of people with COVID-19 will get conjunctivitis, also called pinkeye. It happens when the virus infects a tissue called conjunctiva, which covers the white part of your eye or the inside of your eyelids. Symptoms include if your eyes are:
- Red
- Swollen
- Itchy
If you have conjunctivitis, it doesn’t necessarily mean you have COVID-19. The more likely causes are the many different viruses, bacteria, chemicals, and allergens that can irritate your eyes.
Many forms of conjunctivitis go away with over-the-counter treatments in about 1-2 weeks.
But if you also have a fever, cough, or shortness of breath, ask your doctor what, if anything, you should do. Call before you head to a hospital or a medical center to see if it’s safe for you to visit and for any instructions for your arrival.
How the Infection Spreads
The new corona virus, named SARS-CoV-2, gets passed on primarily through droplets from a cough or a sneeze. These particles most often enter through your nose or mouth as well as your eyes. It’s also possible to catch the virus if you touch a contaminated countertop, doorknob, or other surfaces. But this doesn’t seem to be the main way the virus spreads.
If you have conjunctivitis from COVID-19, you may infect others with SARS-CoV-2 if you touch your eyes and then touch people or surfaces without washing or disinfecting your hands. Avoid touching your face, especially the mucous membranes in your mouth, nose, and eyes.
