When To Keep A Sick Child Home From School

As Asian parents do we push our children too hard to foster talent that we expect them to have?

Seven in the morning, a child who’s warm but cheerful, and two adults who both have something at work they can’t move. The decision gets made in about ninety seconds and it’s usually made badly, in whichever direction the day is pushing.

Two questions settle most of these.

Are they contagious? If yes, they stay home regardless of how well they seem. This is the one that isn’t about your child. It’s about everyone else’s.
Can they take part in the day? A child who can’t concentrate, can’t eat, or will need to lie down by ten isn’t going to get anything out of school and will need collecting anyway.

“Seems basically fine” isn’t the test. Plenty of contagious children seem basically fine.

Fever

Fever is generally taken as a temperature of 38°C or above, and it’s the clearest keep-home signal there is.

The convention most schools and doctors work to is that a child stays home until they have been free of fever for 24 hours without paracetamol or ibuprofen. That last part is where the mistake usually happens: medicine at 7am produces a comfortable child by 8am and a fever again by lunchtime, in a classroom.

Sending a child in on fever medicine is the single most common way an infection travels through a class.

Common illnesses and what’s usually advised


Condition	Usual guidance
Hand, foot and mouth disease	Stay home. Preschools and childcare centres here take this seriously and report cases; a centre can be closed during an outbreak. Return when a doctor says so, typically once blisters have dried and the child is well.
Chickenpox	Stay home until every blister has crusted over, usually around five to seven days after the rash appears.
Vomiting or diarrhoea	Home until at least 24 hours after the last episode, and many schools ask for 48. Highly transmissible and unpleasant for everyone.
Conjunctivitis	Home while the eye is red and discharging. Spreads quickly among children who touch everything.
Influenza	Home until fever-free for 24 hours without medication, and ideally while the cough is still productive.
An ordinary cold, no fever	Usually fine. A runny nose that keeps a child home would keep most children home most of the year.
Undiagnosed rash	See a doctor before sending them in. A rash with a fever needs checking, not guessing.
Head lice	Not a reason to miss school once treatment has started.

Individual schools and preschools set their own exclusion policies and some are stricter than the general guidance. The centre’s own policy is the one that applies to you, and it’s best read once on a calm day, not at 7am.

The borderline mornings

Most cases aren’t the list above. They’re a child who’s a bit off.

Ate breakfast normally? A child who eats is usually a child who can manage the day.
Up and about, or on the sofa? A child who follows you around the flat is different from one who hasn’t moved.
Slept through, or awake half the night? Exhaustion alone makes for a wasted school day.
Is this the third Monday in a row? A pattern that lands on particular days, or particular subjects, is often about school, not illness, and that’s something to look into gently instead of treating as a lie.

Where it’s 50-50, sending them in with a note to the teacher and a phone kept close is a reasonable middle path. Teachers would generally rather know.

Medical certificates and backup contacts

Absence from a mainstream school is normally covered by a medical certificate, so a GP visit does double duty on the days it’s needed. Preschools and childcare centres vary, and some ask for a doctor’s memo before a child returns after certain infections, particularly hand, foot and mouth disease.

Sort this out before you need it: who’s the backup if both parents are working, and whether a grandparent or helper can collect at short notice. The school will call, and they’ll call the first number on the form.

When it isn’t a school question at all

Some presentations need a doctor the same day, not a decision about attendance: difficulty breathing, a fever in a baby under three months, a child who’s drowsy or unusually hard to rouse, a stiff neck with fever, a rash that doesn’t fade when pressed, persistent vomiting, or signs of dehydration such as very little urine.

Those are reasons to seek medical care promptly, and in the more serious of them, to go straight to a children’s emergency department.

Frequently asked questions

What temperature means my child should stay home?

38°C or above is generally treated as a fever and a clear reason to keep them home. The usual advice is to stay home until 24 hours have passed with no fever and without paracetamol or ibuprofen. A child kept comfortable by medicine in the morning will often spike again by midday.

Can my child go to school with a runny nose?

Usually yes, if there’s no fever and they’re otherwise themselves. Keeping children home for every runny nose would mean missing a large part of the year.

How long should a child stay home with hand, foot and mouth disease?

Until a doctor says they can return, which is typically once the blisters have dried and the child is well. Preschools and childcare centres in Singapore report cases and can be closed during an outbreak, so the centre’s own requirements apply as well.

Do I need a medical certificate?

For mainstream schools an MC is the normal way an absence is covered. Preschools and childcare centres vary, and some ask for a doctor’s memo before a child returns after particular infections.

My child says they’re sick but seems fine. What do I do?

Look at the pattern instead of the one morning. Complaints that cluster on particular days or before particular subjects often point to something happening at school, not to illness, and that tends to respond better to a gentle conversation than to a thermometer.

When should I take my child to a doctor instead?

Difficulty breathing, a fever in a baby under three months, unusual drowsiness, a stiff neck with fever, a rash that doesn’t fade under pressure, persistent vomiting or signs of dehydration all need medical attention promptly, not a decision about school.

What to remember

Contagious means home, however well they look. Fever means home until 24 hours clear without medicine, and the “without medicine” part is the one people skip.

For everything else, ask whether they can take part in the day. And check your school’s own policy once, calmly, not at seven in the morning.
