Yes, COVID-related conjunctivitis is contagious. The virus that causes COVID-19 has been detected in tears and conjunctival secretions, and researchers have confirmed that these ocular fluids can contain live, infectious virus, not just harmless genetic fragments. This means the pink eye that sometimes accompanies a COVID infection can spread the virus to others through direct or indirect contact with eye secretions.
How the Virus Spreads Through the Eyes
The surface of your eye contains the same receptor protein that lines your airways and lungs, the one SARS-CoV-2 latches onto to enter cells. Research published in the Journal of Medical Virology confirmed this receptor is present in the conjunctival epithelium (the thin tissue covering the white of your eye and inner eyelids) in every sample tested from healthy human eyes. That means the virus can both enter your body through the eyes and replicate there once established.
A landmark case study from Italy’s National Institute for Infectious Diseases provided some of the strongest evidence that eye secretions are genuinely infectious. Researchers collected an ocular swab from a hospitalized COVID patient with persistent conjunctivitis, detected viral RNA in the sample, then inoculated lab cells with the fluid. The cells showed clear signs of viral damage within five days, confirming that live, replicating virus was present in the patient’s eye secretions. This distinction matters: detecting viral RNA only tells you the virus was there, while growing it in cells proves it can still infect.
How Long Eye Secretions Remain Infectious
Viral RNA has been detected in conjunctival swabs as long as 12 days after COVID symptoms first appeared. The vast majority of positive eye samples, 15 out of 17 in one observational study, were identified during the first week of illness. Two cases showed positivity on days 11 and 12. This suggests the highest risk of spreading the virus through ocular secretions is in the first seven days, though some people shed virus from their eyes for nearly two weeks.
Patients with more severe COVID infections tend to have higher rates of detectable virus in their tears and conjunctival fluid. If your eye symptoms are mild and your overall COVID case is mild, the viral load in your tears is likely lower, but that doesn’t mean zero.
What COVID Pink Eye Looks and Feels Like
COVID conjunctivitis typically produces redness in one or both eyes, a watery or mucous discharge, a gritty sensation, light sensitivity, and tearing. It tends to look more like viral pink eye than bacterial pink eye: the discharge is usually watery or slightly mucousy rather than the thick, yellow-green pus associated with bacterial infections. You won’t usually wake up with your eyelids crusted shut the way you might with a bacterial case.
One notable pattern emerged during the Omicron XBB.1.16 wave in 2023: non-purulent conjunctivitis (pink eye without pus) appeared in about 37% of SARS-CoV-2 positive infants during that surge. Young infants tested positive at significantly higher rates than older children, 37.4% versus 13.3%, and conjunctivitis was a prominent feature in that age group. This was unusual enough that pediatricians flagged it as a potential early sign of COVID in babies during that period.
How It Spreads to Others
The primary concern isn’t that someone will stare into your eyes and catch the virus. The realistic transmission chain looks like this: you rub or touch your infected eye, the virus transfers to your fingers, and then you touch a surface, another person, or your own nose and mouth. Respiratory droplets from coughing or sneezing can also land on another person’s eyes, establishing infection through the conjunctiva.
Objects matter too. Anything that contacts your face or eyes, including towels, pillowcases, and phones, can carry the virus temporarily. The ocular surface is directly exposed to droplets and contaminated objects, making it both a potential entry point for the virus and a source of further spread through hand contact.
Protecting Yourself and Others
The most effective precaution is straightforward: don’t touch your eyes, and wash your hands thoroughly if you do. If you have COVID conjunctivitis, avoid sharing towels, pillows, or anything that contacts your face. Wash your hands with soap and water for at least 20 seconds before and after touching the area around your eyes.
Contact lens wearers face a specific risk because they touch their eyes regularly. Current guidance is that contact lenses remain safe to wear as long as you practice thorough hand hygiene when inserting and removing them, and you stop wearing lenses entirely if you feel unwell, particularly with cold or flu-like symptoms. If you develop conjunctivitis alongside any respiratory illness, switch to glasses until both conditions resolve. During the pandemic, surveys found that 96% of contact lens wearers reported using soap and water for handwashing, and 87% followed the 20-second rule most or every time. Those habits are worth maintaining.
If you’re caring for someone with COVID who has pink eye symptoms, treat their eye secretions with the same caution you’d apply to respiratory droplets. Dispose of tissues immediately, clean shared surfaces, and avoid face-to-face proximity during the first week of symptoms when viral shedding from the eyes is highest.
