Pink eye — also known as conjunctivitis — is one of those things that seems to spread like wildfire, especially among children. It’s uncomfortable, inconvenient, and if you or a loved one has it you’re probably desperate to know: how long is pink eye contagious? The answer depends on the type of pink eye, but we’re here to walk you through the differences and treatment options.
What is Pink Eye?
Pink eye, or conjunctivitis, occurs when the clear, thin tissue that lines your eyelid and eye itself becomes irritated or infected. The result is a red, itchy, watery eye. Sometimes there’s crusting or discharge, especially when you first wake up in the morning. It’s no fun — but thankfully it’s easy to treat.
There are a few different types of pink eye:
- Viral (the most contagious)
- Bacterial (also contagious)
- Allergic (not contagious)
How Long is Pink Eye Contagious?
Viral Pink Eye
If a pink eye infection is caused by a virus (often the same one that causes the common cold), it’s contagious as long as there are symptoms — especially redness and discharge. This can last anywhere from a few days to 2 weeks. This type can also spread to both eyes.
Bacterial Pink Eye
This type is also contagious, but usually less so after 24 hours of antibiotic drops or ointment. If medication isn’t used, bacterial pink eye is contagious as long as symptoms are present. In addition to close contact with contagious individuals, contracting this type of pink eye can stem from improper hand washing and then touching the eye, or from wearing dirty contact lenses.
