How Long Is Pink Eye Contagious? Viral vs. Bacterial and When You Can Go Back to Work

Written by Naurah Gaspard, DNP, FNP-C, FNP-BC · Medically reviewed by Cherlie Joseph, MSN, FNP-BC · Updated November 2026

Pink eye is contagious for as long as your eye is red, tearing and producing discharge. Viral pink eye usually lasts 7 to 14 days and can stay contagious for much of that time, while bacterial pink eye often improves within a day or two of starting antibiotic drops. Allergic pink eye is not contagious at all.

Contagious period by type

Pink eye (conjunctivitis) is inflammation of the clear lining over the white of the eye and inside the eyelids. The CDC describes viral and bacterial pink eye as very contagious; allergic and irritant pink eye do not spread.

Type	How long it lasts	How long it is contagious
Viral	Usually 7 to 14 days; sometimes 2 to 3 weeks or longer (CDC)	While the eye is tearing and producing discharge, which can be up to about 14 days
Bacterial	Often 2 to 5 days; up to 2 weeks without treatment (CDC)	While discharge continues; antibiotic drops shorten this
Allergic	As long as you are exposed to the allergen	Not contagious
Irritant (smoke, chlorine, chemicals)	Usually a day or so after the exposure ends	Not contagious

The American Academy of Ophthalmology explains it simply: pink eye is contagious as long as the eye keeps tearing and producing discharge.

How to tell which type you have

• Viral: watery discharge, a gritty or burning feeling, often starts in one eye and spreads to the other within a few days. Commonly comes with a cold, sore throat or runny nose. Antibiotics do not help.
• Bacterial: thicker yellow or green discharge that can glue the lashes shut in the morning. May affect one or both eyes.
• Allergic: both eyes, intense itching, watery discharge, often with sneezing and an itchy nose. Very common during Florida's long pollen seasons.

A provider can usually tell the type from your symptoms and history. If antibiotic drops are prescribed and you see no improvement after 24 hours, the CDC advises checking back with your provider.

When adults can return to work

There is no single legal rule for adults, and many workplaces do not require you to stay home for mild pink eye. The CDC advises staying home if you also feel sick (for example, fever or body aches), especially if your job means close contact with others, and returning once a clinician says it is okay and any recommended treatment has started.

Practical guidelines many providers use:

• Bacterial: many people can go back once they have used antibiotic drops for about 24 hours and the discharge is clearly improving.
• Viral: return when tearing and discharge are greatly improved. If you must work sooner, avoid close contact, do not share equipment, and wash your hands often.
• Allergic or irritant: no need to stay home.

If you work in health care, child care, food service or with older adults, check your employer's policy, since stricter rules often apply. Our guide to pink eye treatment online explains what a visit includes.

How to avoid spreading it at home

Pink eye spreads mostly from hands to eyes, through touching your eye and then a doorknob, phone or towel. The CDC recommends:

• Wash your hands with soap and water often, especially after touching your eyes or applying drops.
• Avoid touching or rubbing your eyes.
• Use a separate towel, washcloth and pillowcase, and wash them in hot water.
• Do not share eye drops, makeup, glasses or contact lens cases.
• Use a clean tissue or cotton pad for each wipe, and do not use the same bottle tip or cloth on an infected and a healthy eye.
• Wipe down shared surfaces like phones, remotes and faucet handles.

Cool compresses and preservative-free artificial tears can ease discomfort while viral pink eye runs its course.

Contact lenses and eye makeup

Stop wearing contact lenses until your eye provider says it is okay, or, if you have not been seen, until your symptoms are completely gone. The CDC notes that contact lens wearers with bacterial pink eye should be evaluated promptly by an eye doctor, because they are at higher risk of a serious corneal infection. Throw away disposable lenses and the case you used while infected, and replace eye makeup such as mascara and eyeliner that may have been contaminated.

Frequently asked questions

Is pink eye contagious after 24 hours of antibiotics?

For bacterial pink eye, the risk drops quickly once drops are started, and many people can return to work after about 24 hours of treatment if discharge is improving. Antibiotics do not shorten viral pink eye.

Can you get pink eye from a pillow?

Yes. Viral and bacterial pink eye can spread through shared pillowcases, towels and bedding. Use your own and wash them in hot water.

Is pink eye contagious if there is no discharge?

Viral pink eye can still spread through tears even when discharge is watery rather than thick. Allergic pink eye, which usually causes itchy, watery eyes in both eyes, is not contagious.
