Scarlet Fever: How Long Off School, and Getting Through Nights

A child with scarlet fever stays off school or nursery until 24 hours after their first dose of antibiotics, according to the NHS. So if the GP prescribes on Monday afternoon and the first dose goes in at 4pm, the rule is met at 4pm on Tuesday, as long as your child feels well enough to go. The illness itself lasts around a week. The nights are mostly about a sore throat and a high temperature: cool drinks, soft food, paracetamol and an earlier bedtime for both of you. The first job is to phone the GP, because scarlet fever needs antibiotics and the clock doesn’t start without them.

What it looks like: sore throat first, rash second

The NHS scarlet fever page says the first signs “can be flu-like symptoms, including a high temperature, a sore throat and swollen neck glands”. Then “a rash appears 12 to 48 hours later”. It “looks like small, raised bumps and starts on the chest and tummy, then spreads”, and it “makes your skin feel rough, like sandpaper”.

That texture is the useful sign, because colour is unreliable. The NHS says on brown and black skin “it might be harder to see a change in colour, but you can still feel the rash and see the raised bumps”. So run your hand over their tummy. Don’t just look.

The same page describes a white coating on the tongue that peels to leave it red and bumpy (strawberry tongue).

Ring the GP first, and don’t just turn up

The NHS says to see a GP if you or your child have scarlet fever symptoms. But it also says scarlet fever “spreads very easily”, so “check with a GP before you go in. They may suggest a phone consultation.”

Phone at 8am and let the surgery decide how they want to see you. A GP “can often diagnose scarlet fever by looking at your tongue and rash”.

If it is scarlet fever, the NHS says a GP will prescribe antibiotics, which help your child get better quicker and make it less likely they’ll pass it on. It also says: “Keep taking the antibiotics until they’re finished, even if you feel better.” By day three your child will look fine and fight every spoonful. Finish the bottle anyway.

How long off school, exactly

The NHS says: “stay away from nursery, school or work for 24 hours after you take the 1st dose of antibiotics.”

The UK Health Security Agency’s A to Z for children’s settings, the guidance schools and nurseries in England work from (elsewhere in the UK, ask the school), says stay away “until 24 hours after they started treatment with antibiotics”. Without antibiotics, the NHS says you can spread the infection “for 2 to 3 weeks after your symptoms start”. That’s another reason to phone the GP on day one.

What that means for your week:

• Count the 24 hours from the first dose, not from the appointment or the day the rash appeared.
• 24 hours is the minimum. A child who still has a high temperature or can’t swallow breakfast isn’t ready, whatever the clock says. The UKHSA page says the fever “typically lasts 1 to 2 days”, so many children need a day or two more at home.
• Tell the school or nursery it’s scarlet fever when you report the absence, and ask if they have their own return rule.

Can brothers and sisters still go in?

Yes. The UKHSA guidance says close contacts “can come to the setting as usual, as long as they do not have symptoms. This includes siblings or household members.” They should get medical advice if they develop symptoms.

At home, the NHS says wash hands often, bin tissues quickly, and “do not share cutlery, cups, towels, clothes, bedding or baths with anyone else”. So the poorly child gets their own towel and cup, and the shared bath is off for the week.

The nights: throat, temperature, itch

The NHS self-care list for scarlet fever is short:

• Cool fluids. Keep a cup of water by the bed and offer sips every time they wake.
• Soft foods for the sore throat. Yoghurt, mashed potato, soup that has cooled down, porridge.
• Paracetamol “to bring down a high temperature”, following the dose on the packet for your child’s age. The NHS says “do not give aspirin to children under 16”.
• For itching, the NHS lists “calamine lotion or antihistamine tablets”. Ask the pharmacist what suits your child’s age before you buy either.

The NHS sore throat page also suggests ice lollies, but warns: “do not give young children anything small and hard to suck because of the risk of choking”. So lollies yes, boiled sweets no.

Then go to bed when they do. You’ll be up at 1am, and you have no one to swap with.

Keep the steps of bedtime in the usual order, even if they wake three times afterwards. My post on baby sleep when sick covers the extra cuddles and why one rough week doesn’t undo a routine. For babies, the safer-sleep basics don’t change when they’re ill: on their back, in a clear cot, with the room at 16 to 20°C. Once the antibiotics are finished and everyone is well, Betteroo has a guide to getting nights back on track after an illness.

When to go back to the GP, and when it’s urgent

The NHS says see a GP again if your child:

• does “not get better in a week” after seeing a GP
• has “scarlet fever and chickenpox at the same time”
• is “ill again, weeks after scarlet fever got better”, because “this can be a sign of a complication, such as rheumatic fever”

If both are going round the same class, my chickenpox post has the different medicine rules for that one.

For any sore throat, the NHS says call 999 or go to A&E if your child has “difficulty breathing” or is “unable to swallow”, is drooling, or is making a high-pitched sound as they breathe. Ask for an urgent GP appointment or use 111 for signs of dehydration, “such as peeing less than usual or dark, strong-smelling pee”.

Covering work when there’s only you

Scarlet fever is easier on your job than chickenpox, because the off-school rule is a day and not a week. A realistic plan is two or three days.

GOV.UK’s time off for dependants page says employees are “allowed a reasonable amount of time off to deal with the emergency”, and its own example fits: “If your child falls ill you could take time off to go to the doctor and make care arrangements.” On pay, your employer “may pay you for time off to look after dependants but they do not have to”. Check your contract before you phone in.

1. Day one: phone the GP at 8am, then your manager, and say the rule is 24 hours after the first antibiotic dose.
2. Day two: ask about working from home or swapping a shift.
3. Line up one back-up person. Tell them straight that it’s scarlet fever and when the 24 hours ends. If they’re pregnant, the NHS advice is to avoid close contact with anyone who has it.

FAQ

How long is a child off school with scarlet fever?

Until 24 hours after their first dose of antibiotics, under NHS and UKHSA guidance. They also need to feel well enough to go back, so many children are off for two or three days.

Do siblings have to stay off school too?

No. UKHSA guidance says siblings and household members can attend as usual as long as they have no symptoms. Get medical advice if they develop any.

What does the scarlet fever rash feel like?

The NHS describes small, raised bumps that make the skin feel rough, like sandpaper. It starts on the chest and tummy and then spreads. On brown and black skin the colour change can be harder to see, but you can still feel it.
