Is tonsillitis contagious? When to see a GP in Ireland

Swallowing tea hurts and the school bag is still in the hall. Here is whether tonsillitis is contagious, how long to stay home, and when to see a GP in Ireland.

It is a wet Monday. Swallowing tea hurts. A child beside you has the same complaint, and the school bag is still in the hall. That is usually when people search "is tonsillitis contagious" and hope the answer is one day on the couch.

A runny nose and a tickly cough are often a cold. This page is for the tonsils, the two lumps at the back of the throat. They go red and swollen. Swallowing is the hard part. For a general cold, read cough or cold in Ireland. A wider sore throat has its own page.

Book an appointment if you already want a GP and you can still drink. The short introduction to a visit is on the online GP page. How it works, services, and pricing show the steps and the live fee.

What tonsillitis is

The HSE describes tonsillitis as common in children. Teenagers and adults get it too. It can feel like a bad cold. The tonsils at the back of the throat are red and swollen.

You may have a sore throat, trouble swallowing, a hoarse voice, and a temperature of 38 degrees Celsius or more. A cough, headache, or earache can join in. Neck glands can swell. White spots can appear on the tonsils, and your breath can smell bad.

Symptoms often ease in 3 to 4 days. Read HSE: tonsillitis.

If the pain is mostly in the ear, see earache in Ireland. If it sits in the cheeks or forehead, see sinus pain in Ireland.

Is tonsillitis contagious?

You can pass on the cough or cold that set the tonsils off. A cough or sneeze can carry those germs. Sharing a cup can too.

The HSE asks you to use a tissue when you cough or sneeze, bin it, and wash your hands. Do not share towels or cups while someone in the house is unwell.

Stay off work until you feel better. Keep a child at home until they do. A mild sore throat on its own, in a child who otherwise feels well, is different. The HSE says that child can still go to school. A sore throat plus a high temperature means stay home until the temperature is normal.

Staying off school or work

The HSE tonsillitis page says you may need to stay off work until you feel better, or keep your child at home until they do.

The HSE sore-throat page is about going back. Do not go to work, school, or creche with an infection. You can return when symptoms have been gone for 48 hours. That page was reviewed on 21 February 2025. Read HSE: sore throat.

Phone the school on the first morning. Say the child will not be in, and why.

What you can try at home

While the 3 or 4 days pass, and you can still drink:

  • Rest.
  • Drink cool drinks. They soothe the throat.
  • Eat cool, soft food if chewing hurts.
  • Adults can gargle warm salty water, then spit it out. Do not swallow it. Children should not gargle salt water.

A pharmacist can advise on pain relief. The HSE gargle is half a teaspoon of salt in a glass of warm water. Younger children should skip it.

The GP decides on treatment where clinically appropriate. Booking does not guarantee a prescription. Paying for the visit does not buy treatment.

When to see a GP for tonsillitis

Contact a GP if white spots are on the tonsils, if eating or drinking is difficult, if symptoms are not gone after 4 days, or if tonsillitis keeps coming back.

The GP can usually tell by asking and looking. They may want a swab if it will not settle. Having the tonsils taken out is rare, and a specialist decides.

Red flags: emergency department

Call 112 or 999, or go to the emergency department, if breathing is hard, swallowing is hard, or you cannot swallow your saliva and you are drooling. Go if speaking is difficult, you cannot open your mouth, or one side of the throat swells fast.

That one-sided swelling can be quinsy, a pocket of pus beside a tonsil. A sore throat that gets worse quickly belongs in the same urgent group. So does a child who will not drink, has dry nappies, or is very sleepy and hard to wake.

Do not wait on a video link for those.

When a phone or video visit can fit

A phone or video visit can suit someone who can talk, can drink, and is not in the list above. Video helps if you can show the throat in good light. Hold the phone still. Video or phone walks through that choice.

The GP may still want an in-person look or a swab. A remote visit cannot drain a quinsy.

A note for school or work is a separate decision, after the GP has spoken with you. Read how to get a sick cert online in Ireland. The GP still decides. Paying for the visit does not buy the note. Some Illness Benefit forms still need your registered GP.

Frequently asked questions

Is tonsillitis contagious?

You can pass on the cough or cold behind it. Stay home while you feel unwell, use a tissue, and wash your hands. A child with only a mild sore throat, who feels well, can often still go to school.

How long should we stay off school or work?

Stay off until you feel better. HSE sore-throat advice is to go back when symptoms have been gone for 48 hours. Many people turn the corner in 3 to 4 days.

When should I see a GP for tonsillitis?

See a GP if there are white spots, drinking is difficult, or it has not eased after 4 days. Call 112 or 999, or go to the emergency department, if breathing, swallowing, or opening the mouth is hard.

Can I get a sick cert for tonsillitis?

Only if a GP assesses you and decides you are unfit for school or work. Paying for the visit does not buy the note.
