Neo-natal conjunctivitis

A more severe type of conjunctivitis that can affect newborn babies younger than 28 days is called neo-natal conjunctivitis.

Neo-natal conjunctivitis can occur if a baby is born to a mother who has a sexually transmitted infection such as chlamydia or gonorrhoea (these don't necessarily cause symptoms, so many mothers are unaware that they're infected).

Most cases of conjunctivitis in babies are not particularly serious. But there is a small possibility of serious complications if it's left untreated.

So if you notice any redness in your baby’s eyes, contact your GP for advice.

Conjunctivitis is redness and inflammation of the thin layer of tissue that covers the front of the eye (conjunctiva). It is very common.

People often refer to conjunctivitis as red eye.

Other symptoms of conjunctivitis include itchiness and watering of the eyes, and sometimes a sticky coating on the eyelashes (if it's caused by an allergy). Read more about the symptoms of conjunctivitis.

Conjunctivitis can affect one eye at first, but usually affects both eyes after a few hours.

What causes conjunctivitis?

The conjunctiva can become inflamed as result of:

  • a bacterial or viral infection – this is known as infective conjunctivitis
  • an allergic reaction to a substance such as pollen or dust mites – this is known as allergic conjunctivitis
  • the eye coming into contact with substances that can irritate the conjunctiva, such as chlorinated water or shampoo, or a loose eyelash rubbing against the eye – this is known as irritant conjunctivitis

Treating conjunctivitis

Conjunctivitis often doesn't require treatment as the symptoms usually clear up within a couple of weeks. If treatment is necessary, the type of treatment will depend on the cause. In severe cases, antibiotic eye drops can be used to clear the infection.

Irritant conjunctivitis will clear up as soon as whatever is causing it is removed.

Allergic conjunctivitis can usually be treated with anti-allergy medications such as antihistamines. If possible, avoid the substance that triggered the allergy.

It's best not to wear contact lenses until the symptoms have cleared up. Any sticky or crusty coating on the eyelids or lashes can be cleansed with cotton wool and water.

Washing your hands regularly and avoiding sharing pillows or towels will help prevent it spreading.

See your GP immediately if you have:

  • eye pain
  • sensitivity to light (photophobia)
  • disturbed vision
  • intense redness in one or both of your eyes
  • a newborn baby with conjunctivitis 

Do you need to stay away from work or school?

Public Health England advises that you do not need to stay away from work or school if you or your child has conjunctivitis, unless you are feeling particularly unwell.

If there are a number of cases of conjunctivitis at one school or nursery, you may be advised to keep your child away from the school until their infection has cleared up.

Generally, adults who work in close contact with others, or share equipment such as phones and computers, should not return to work until the discharge has cleared up.


Conjunctivitis can be a frustrating condition – especially allergic conjunctivitis – but in most cases it doesn't pose a serious threat to health.

Complications of conjunctivitis are rare but when they do occur they can be serious and include:

  • a severe case of allergic conjunctivitis can lead to scarring in the eye
  • in cases of infective conjunctivitis, the infection can spread to other areas of the body, triggering more serious secondary infections such as meningitis (an infection of the outer layer of the brain)

I got conjunctivitis along with a throat and lung infection but left it for a day or two and it got worse. When I got to the hospital they said that if I left it longer it would scar my eye so I would recommend everyone with suspected conjunctivitis to go get it checked as soon as possible but if you can't straight away then clean with a cotton wool ball and warm but not boiling water. The docs will give some eye drops that will manage the infection.

My 1yo has conjuntivitus best way i found to help it till you get to see a doctor is cooled boiled water.... use a cotton bud wipe eye with one side then turn over use otherside.... you only use each side once or it will spread. This advice was given by gp when oldest son had it.

The advice to send children into school is just wrong. My daughter is now on a course of antibiotics due to the selfishness of others. No wonder antibiotics are losing their efficiency. I shall be keeping my daughter home so as not to spread to others.

The web address has been edited out of my last comment which makes it look a bit silly. It was a reference to the NICE guidelines which can be found by googling NICE acute infective conjunctivitis.

The reasons for them recommending continued attendance at school are that they regard it as a mild illness like having a cold, as explained here:

In ny opinion it is extremely irresponsible to advise young children to go to school unless there are "a number of cases" at school or nursary. A mini-epidemic of conjunctivitis is started at a school by a single parent who may take their child to school. As conjunctivitis is extremely contagious, the infection will spread quickly, butif it is "nipped in the bud" it will not spread at all.

The Health Protection Agency and the NHS should really review this official policy.

I am amazed and shocked to read your following advise in the above page.

''Infective conjunctivitis is easily spread, although it isn't necessary to stay away from work or keep your child away from school.''

So you are advising that it is highly contagious but you would like people to go out and spread it at the work place and also at the school and spread the misery to other healthy individuals.

Are you sure that this is the right advise???

It can be a thorough nuisance, affecting my vision, causing a black eye and make me think I am going blind. Got it again this year; now. A & E said it was a virus last time. Best to wait and see your GP. I still do not know how to treat the symptoms. Paracetamol seems as useful as anything.

very helpful - my 2 and half year old has a squint and just been diagnosed with infective conjunctivitis and I was worried about her future eye health - this helps a lot.
