Pink Eye on Holiday: Contagious, Common, and Mostly Manageable

One pink eye in a family room tends to become four. What decides everything is which of the three kinds you are looking at, and that is a question a doctor can usually answer by looking.

Medically reviewed by Dr. Diogo Figueiredo Gonçalves, MD, Specialist Physician in Family Medicine —

General information, not a diagnosis. If you are worried about your symptoms, speak with a doctor.

The short answer

A pink or red eye with swelling, watering, itching or discharge is usually conjunctivitis, which CDC calls one of the most common and treatable eye conditions. The three usual causes are viruses, bacteria and allergens; the viral and bacterial kinds are very contagious, so on holiday the first job is hygiene: hand washing and separate towels. Some types can be managed at home without medical treatment. If you have a flight coming up, the question is less the flight than how contagious you are: allergic pink eye is not contagious at all, and AAO says bacterial pink eye can spread until about 48 hours after starting antibiotics. One absolute red flag: a newborn with pink eye symptoms should be seen by a doctor right away, because infectious neonatal conjunctivitis can be very serious.

Worth knowing

  • Three causes, three stories: viruses, bacteria and allergens are CDC's most common causes. Viral and bacterial pink eye are very contagious; allergic is not.
  • The symptoms overlap: pink or red whites, swollen lids, watery eyes, a gritty something-in-the-eye feeling, itching and burning, discharge of pus or mucus. Cause changes the details, which is why a look from a doctor helps.
  • Holidays are built for spreading it: shared towels, family beds, pool days. CDC's prevention is simple hygiene, starting with hand washing and not touching the eyes.
  • Contact lens wear and chemicals are on CDC's cause list too. On a beach holiday, a red eye in a lens wearer deserves attention rather than another day of wear.
  • Flying with it: CDC and AAO set no boarding rule for passengers. What decides the flight is contagiousness, so glasses instead of lenses, clean hands, your own tissues and drops, and a doctor first if there is pain, light sensitivity or blurred vision.
  • Newborns are the emergency case: CDC says a newborn with pink eye symptoms should see a doctor right away.
In this guide

What is pink eye?

CDC's description: conjunctivitis makes the white of the eye turn pink or red because the thin layer lining the eye and inner eyelid becomes inflamed, which makes blood vessels more visible. The symptom set is familiar to any parent: redness or swelling, watery and teary eyes, the feeling that something is in the eye and the urge to rub it, itchiness and burning, and discharge of pus or mucus that can crust overnight. Symptoms vary with the cause, and one or both eyes can be involved.

The cause list is short and it decides everything: viruses, bacteria and allergens are the most common, with chemicals, contact lens wear and foreign bodies such as a loose eyelash also on CDC's list. Viral and bacterial pink eye are very contagious. Allergic pink eye is not, and tends to come with the rest of the allergy picture.

Why does pink eye spread so easily on holiday?

CDC's core facts are that viral and bacterial conjunctivitis spread easily from person to person, and that prevention is a matter of simple hygiene. A holiday concentrates the risky habits: shared towels at the pool, children rubbing eyes after a day of sun cream and salt water, family rooms where everyone touches everything. The practical CDC-grade rules for a travelling family: wash hands often and well, keep the affected person on their own towel and pillow, and avoid touching or rubbing the eyes, which spreads it to the other eye and to everyone else. CDC's list for someone who has pink eye also says plainly: do not use swimming pools.

Can you fly with pink eye?

Usually, yes, and the eye is rarely the problem. CDC and the American Academy of Ophthalmology, the two sources this article relies on, set no rule for passengers flying with conjunctivitis. What they do set out is who is contagious and for how long, and that is what should shape a flight home or a flight onward.

  • Allergic pink eye is not contagious at all, per CDC and AAO. Itchy, watery eyes that arrived with the pollen or the dust are not a reason to change a flight.
  • Bacterial pink eye can be spread from the time symptoms start until about 48 hours after starting antibiotic treatment, according to AAO. CDC notes that mild bacterial cases usually clear in 2 to 5 days even without treatment, though they can take up to 2 weeks.
  • Viral pink eye is the long one. CDC says most cases clear in 7 to 14 days without treatment, and some take 2 to 3 weeks or more. Antibiotics do nothing for it, so a flight in the middle of it is a hygiene exercise rather than a timing one.

On the plane

The CDC hygiene list travels well. Wash your hands often, and where there is no soap use an alcohol-based sanitiser with at least 60% alcohol. Do not touch or rub your eyes. Do not share tissues, towels, eye drops or eye make-up with the person next to you, including the person you are travelling with. Stop wearing contact lenses until the symptoms are gone, or until an eye doctor says you can start again, so pack your glasses in your hand luggage. Keep any drops you have been given with you rather than in the hold.

Whether you board is the airline's decision, not a health authority's. If your eye is visibly weeping and you are worried about it, ask the airline before you travel rather than at the gate.

Does pink eye need treatment?

CDC's treatment position is honest and useful: options depend on the cause, and some types of pink eye can be managed at home without medical treatment. That is the good news for a mild watery case in an otherwise well child. The judgement is in the sorting, because the causes look alike at first glance, and the answer changes what you do about towels, the pool, the kids' club and whether any medicine is worth it.

What should you do if pink eye starts mid-trip?

Everything above is CDC's and AAO's guidance. This section is ours. The classic holiday version: day three at the pool, one child wakes with a crusted, pink eye, and the questions arrive together. Can she swim? Does he go to kids' club? Do we all stop sharing the sunscreen tube and towels? The hygiene answers start immediately regardless of cause: hands, towels, no eye rubbing. For the medical answer, our destinations offer routes: in Malta a private GP at most pharmacies can look the same day, covered on our Malta guide; in Portugal SNS 24 points you to the right place, and our Portugal guide explains the system; in Morocco round-the-clock pharmacies help with basics at any hour, with the fuller route on our Morocco guide.

Can a video doctor treat pink eye?

Often, yes. Conjunctivitis is one of the best fits for a video consultation there is, because the condition is visible. A doctor can look at the eye on camera, ask about discharge, itch, allergy history and contact lenses, take a view on which of the three kinds this most likely is, advise whether it is a manage-at-home case per CDC or one that needs treatment, and answer the practical family questions: pool, kids' club, and how long the towel quarantine lasts.

What a video doctor cannot do: examine a newborn's eye, which CDC says needs a doctor right away and in person, or handle cases with significant pain, vision change or injury, which need direct examination. A consultation sorts the ordinary from the urgent; the urgent goes to a clinic, and the doctor will say so plainly. If you are travelling and want that conversation now, you can speak to an online doctor from wherever you are staying.

This article is about what a pink eye means for everyone else on the trip. If the question you actually have is about the eye in front of you, meaning what the symptoms point to, what to do about contact lenses, and which signs mean it is not conjunctivitis at all, then conjunctivitis and what to do about it while travelling is the page for that.

Common questions

Can you fly with pink eye or conjunctivitis?

Usually, yes. CDC and AAO set no boarding rule for passengers; the question is how contagious you are. Allergic pink eye is not contagious. AAO says bacterial pink eye can spread until about 48 hours after starting antibiotics, and CDC says viral pink eye usually lasts 7 to 14 days. On the plane: clean hands, no eye rubbing, glasses instead of contact lenses, your own tissues and drops. See a doctor before flying if you have eye pain, light sensitivity or blurred vision that does not clear.

Is pink eye contagious?

The viral and bacterial kinds are very contagious and spread easily from person to person, per CDC. Allergic pink eye is not contagious. Since the kinds look similar early on, hygiene (hand washing, separate towels, no eye rubbing) is the sensible default from the first symptom.

Can my child go to the hotel pool or kids' club with pink eye?

Not the pool: CDC's advice for anyone with pink eye is not to use swimming pools. For the kids' club, CDC's return guidance for school and work maps across: not while symptoms continue if the activity involves close contact with others, and a return without fever or other symptoms may be allowed with a doctor's approval. A quick consultation can give a family that answer for their specific case.

Does pink eye need antibiotic drops?

Not necessarily. CDC says treatment depends on the cause and some types can be managed at home without medical treatment. Viral cases and allergic cases are not helped by antibiotics at all. The useful step is identifying which kind this is, which a doctor can usually judge from a look and a few questions.

What if a baby has a red or watery eye?

See a doctor right away. CDC is explicit that newborns with pink eye symptoms should be seen immediately, because neonatal conjunctivitis caused by infection can be very serious. This is the one version of pink eye with no wait-and-see.

I wear contact lenses. Anything different?

Contact lens wear is on CDC's cause list for conjunctivitis. A red, irritated eye in a lens wearer on holiday deserves attention rather than continued wear, and it is worth telling the doctor about your lenses at the start of any consultation about an eye.

Is this medical advice?

No. It is general information based on CDC's and AAO's public conjunctivitis guidance, with the sources linked below. It has been reviewed by a doctor for medical accuracy, named at the end of the article, but it does not replace a consultation with a doctor about your own situation.
