If your child wakes up with red, sticky eyes, you might be dealing with conjunctivitis - commonly known as pink eye. It’s a frequent childhood condition, especially among babies and toddlers. But is it contagious? And when should you worry?

Let’s explore what UK health professionals have to say.

What Is Conjunctivitis?

Conjunctivitis is the inflammation of the thin layer of tissue that lines the eyelid and covers the white part of the eye (the conjunctiva). There are three main types, and not all are contagious:

  1. Infectious Conjunctivitis: Caused by viruses or bacteria and is the only type that is contagious. It can spread through direct contact or shared items like towels and pillows (NHS, 2024).

  2. Allergic Conjunctivitis: Triggered by allergens such as pollen, dust mites, or pet dander. This form is not contagious (Moorfields Eye Hospital).

  3. Irritant Conjunctivitis: Caused by exposure to chemicals, smoke, or chlorine. This type is also not contagious.

Symptoms to Look For

Common signs of infectious conjunctivitis in children include:

  • Red or pink eyes

  • Watery or sticky discharge (may cause eyelids to stick shut)

  • Itchiness or grittiness

  • Swollen eyelids

  • Light sensitivity

Infectious conjunctivitis often begins in one eye and spreads to the other, (Association of Optometrists).

Is It Contagious?

Yes, infectious conjunctivitis is contagious, especially in young children who may rub their eyes frequently. It spreads through:

  • Touching the eye and then touching surfaces or others

  • Sharing towels, bedding, or flannels

  • Poor hand hygiene

To prevent spread, wash your child’s hands regularly, use separate towels for each family member, and avoid school or nursery if discharge is heavy (NHS, 2024).

How Is It Treated?

Most cases of conjunctivitis are mild and clear up within 1–2 weeks on their own. For viral infections, no treatment is usually needed, though lubricating eye drops may ease discomfort.

If the infection is bacterial, your pharmacist or GP may recommend antibiotic eye drops or ointment, particularly if symptoms are severe or persist.

When Should You Seek Medical Advice?

Speak to your GP or health visitor if:

  • Your baby is under 28 days old and has red or sticky eyes

  • There’s persistent redness or pain

  • Vision seems affected

  • Symptoms don’t improve after two weeks

For babies, it's especially important to rule out other causes of eye discharge, such as blocked tear ducts or more serious infections (SYB Healthier Together).
