Most people with pink eye need to stay home for about 5 to 7 days, though the exact timeline depends on whether the infection is viral, bacterial, or not infectious at all. The simplest rule: you’re still contagious as long as your eyes are tearing and producing discharge, so that’s when you should avoid school, work, and close contact with others.
Viral Pink Eye: The Longest Wait
Viral conjunctivitis, the most common type, is also the most stubborn. It’s caused by the same family of viruses behind many colds, and there’s no antibiotic that speeds it up. Symptoms typically last 7 to 14 days, and you remain contagious for much of that time. If adenovirus is the cause (as it often is), you can stay infectious for 7 days or longer, even after your eyes start to feel better. The virus can continue shedding from your body after you recover, particularly if your immune system is weakened.
Because there’s no treatment to shorten the contagious window, the practical answer for viral pink eye is: stay home until the tearing and crusty discharge stop. For most people, that means roughly 5 to 7 days from when symptoms began, though some cases stretch to two weeks.
Bacterial Pink Eye: Antibiotics Shorten the Timeline
Bacterial pink eye tends to produce thicker, yellow-green discharge and often affects one eye before spreading to the other. The good news is that antibiotic eye drops or ointment can significantly cut down how long you’re contagious. Occupational health guidelines for healthcare workers recommend staying out of work until the constant tearing stops and you’ve been on effective antibiotic treatment for at least 24 hours. Many schools and daycares follow a similar 24-hour rule.
Without antibiotics, bacterial conjunctivitis can remain contagious for as long as symptoms persist, which may be up to 10 days. With treatment, most people can safely return to normal activities within 2 to 3 days.
Allergic Pink Eye Isn’t Contagious
Not all pink eye requires staying home. Allergic conjunctivitis, triggered by pollen, pet dander, or dust, is not contagious. The same is true for pink eye caused by irritants like chlorine, smoke, or a foreign object. If your eyes are red and itchy but the cause is seasonal allergies rather than an infection, there’s no reason to isolate. The key difference: allergic pink eye almost always affects both eyes, causes intense itching, and comes with other allergy symptoms like sneezing or a runny nose, but it doesn’t produce the thick, sticky discharge that signals a contagious infection.
Signs You’re No Longer Contagious
Rather than counting days on a calendar, watch your symptoms. Pink eye remains contagious as long as your eyes have excess tearing and matted, crusty discharge. Once those signs clear up, you’re generally safe to return to work or school. Specifically, look for these changes:
- No more discharge. Your eyelids aren’t stuck together in the morning and you’re not wiping away gunk throughout the day.
- Tearing has stopped. Your eyes may still be slightly pink, but they’re no longer watering constantly.
- No fever. If you had any systemic symptoms like a fever alongside your pink eye, those should be gone.
Some redness can linger for a few days after you’re no longer contagious. A slightly pink eye without discharge doesn’t necessarily mean you need to keep staying home.
School and Daycare Policies
Guidelines have actually loosened in recent years. The CDC advises that students with viral or bacterial conjunctivitis should stay home if they have systemic signs of illness or can’t avoid close contact with others. But a child who has no fever, can keep their hands clean, and can avoid rubbing their eyes and touching classmates may be allowed back sooner. Younger children in daycare, who are constantly sharing toys and touching each other, usually need to stay home until symptoms fully clear because good hygiene just isn’t realistic for toddlers. Check with your specific school or daycare, as policies vary.
Workplace Guidelines
For adults, the calculus is simpler. If you work in healthcare or food service, or any role involving close physical contact, stay home until discharge stops. Healthcare workers with confirmed adenoviral conjunctivitis may need a doctor’s clearance before returning, since they can remain infectious for over a week. For office workers or people who can work at a distance from others, returning once you’ve been on antibiotics for 24 hours (bacterial) or once discharge has stopped (viral) is the standard approach. Remote work, if available, is an obvious option that lets you stay productive without risking your coworkers’ eyes.
Preventing Spread While You’re Home
Staying home only helps if you’re not infecting the rest of your household. Pink eye spreads through direct contact with eye discharge or contaminated surfaces, so a few habits make a big difference. Wash your hands with soap and water for at least 20 seconds before and after touching your eyes, applying eye drops, or handling anything near your face. Use a clean, wet washcloth or fresh cotton ball each time you wipe discharge from your eyes, and throw cotton balls away immediately. Wash used washcloths with hot water and detergent.
Don’t share pillows, towels, washcloths, or eye drops with anyone. Wash your pillowcases, sheets, and towels frequently in hot water. If you wear contact lenses, stop wearing them until your symptoms are completely gone, and throw away any disposable lenses or cases you used while infected. The same goes for any eye makeup you applied during the infection.
If you use eye drops, don’t let the bottle tip touch your eye, and never use the same bottle for an infected eye and a healthy one. This sounds minor, but it’s one of the most common ways people spread pink eye to their other eye or reinfect themselves after they start to improve.
