What Happens When You Take a Feverish Child to A&E in Singapore
Most children who go to A&E with a fever are examined, sometimes tested, and sent home the same day with advice on what to watch for. Here's when to go now versus wait, what happens at triage, when blood tests come in, and what to bring with you.
Should you go now, or can it wait?
If your child has a fever alongside any of the following, call 995 or head to your nearest 24-hour A&E or children's emergency department, as shown below. Go as soon as you see the sign. Do not give medicine first and wait to see if it works.
Call 995 now if your child has a fever and any of these:
- !A seizure lasting more than 5 minutes (give rectal diazepam if a doctor has prescribed it, and still call)
- !Struggling to breathe (skin pulling in under the ribs, nostrils flaring, or grunting), pauses in breathing, or lips turning blue or grey
- !Cannot be woken, or floppy and not responding to you
- !A rash of small red or purple spots that does not fade when you press a glass on it
- !Swelling of the lips, tongue, or face, with any difficulty breathing
- !Cold, clammy, or mottled skin, with drowsiness or restlessness
Go to the nearest 24-hour A&E or children's emergency now if:
- !A baby under 3 months with a temperature of 38.0°C or above
- !A first febrile seizure, even if it has stopped
- !After a seizure: confused, still drowsy after 30 minutes, or more than one seizure in a day
- !A stiff neck, or crying in pain when bending the head forward
- !Unusually drowsy or hard to wake, but can be woken
- !Dengue warning signs as the fever comes down: tummy pain, repeated vomiting, bleeding gums or nose, or very tired
- !No urine or wet nappy for 12 hours or more
- !No tears when crying, sunken eyes, or a very dry mouth
- !Cannot keep any fluids down
- !Green vomit
- !A temperature above 40°C that is not coming down, and your child seems unwell
Temperature on its own is rarely the deciding factor. A temperature above 40°C that is not coming down, in a child who seems unwell, is a reason to go. How your child looks and behaves matters more than the number.
A temperature around 40°C in a child who is alert, drinking, and perks up between doses is not automatically an emergency by itself. It is the point where it is worth checking when the last dose was given, watching closely over the next hour, and treating any of the signs above as the cue to go rather than waiting longer.
What happens when you arrive: triage
A nurse usually checks your child's temperature, heart rate, breathing, and general appearance soon after you arrive. This is triage. It decides how urgently your child needs to be seen, not the order you arrived in. A child who looks more unwell may be seen before someone who has been waiting longer, including you.
The wait to see a doctor and start any treatment after that varies a lot depending on how busy the department is and how many more urgent cases are ahead of yours. It can be a short wait, or it can take a while. Bring water, snacks, and something to keep your child occupied.
What the doctor checks, and when blood tests come in
The doctor will examine your child much like a GP would: ears, throat, chest, tummy, skin, and signs of dehydration, alongside asking about the timeline of the fever and any other symptoms.
If the doctor wants more information, a blood test may follow. For a suspected bacterial infection, this usually means a full blood count and CRP, markers of how the body is responding, sometimes alongside a blood culture if a more serious infection is suspected. The results help decide whether your child needs antibiotics or further treatment.
In Singapore, a high fever with no obvious cause is also often checked for dengue. The NS1 antigen test can pick up dengue from early in the illness, often from the first day of fever, while a full blood count tracks platelet count and hematocrit, which tend to change as dengue progresses. A normal result on day one does not rule dengue out, which is why a repeat blood test a day or two later is common if dengue is suspected. Alongside any results, the doctor will also ask about bleeding gums or unusual bruising, persistent vomiting, severe tummy pain, or unusual drowsiness, these matter as much as the numbers.

For babies and toddlers who can't sit still for a blood draw, blood is usually taken from a vein in the hand or the inside of the elbow, with a parent helping to hold them steady rather than the calmer process an older child or adult experiences. Numbing cream applied beforehand can help if there is time to wait for it, and a cuddle or feed afterward usually settles your child quickly. A small bruise at the site is normal.
What usually happens next
Most children who go to A&E with a fever are examined, sometimes tested, and sent home the same day with advice on what to watch for and when to come back. This is the most common outcome, not a sign that the visit wasn't worth it.
Sometimes the doctor will want to observe your child for a few hours, to repeat a blood test, give fluids, or see how the fever responds to medicine, before deciding on the next step.
Admission happens when a child needs more support than can be managed at home, for example fluids given through a drip, antibiotics given into a vein, or closer monitoring overnight.
What to bring with you
- Your child's identification (birth certificate with NRIC, or NRIC card for older children) and your own, for registration.
- A note of when the fever started, the highest temperature you have recorded, and the time, medicine, and dose of the last one given. This dose history is one of the first things the triage nurse or doctor will ask about.
- Your child's health booklet with vaccination records, if you have it.
- Water, snacks, a change of clothes, and something familiar like a favourite toy. Visits can take longer than expected.
Most children's emergency departments also limit how many adults can be at the bedside with a child, often to one or two. If grandparents, a helper, or other family members come along, it is worth deciding beforehand who goes in with your child, since others may need to wait in a separate area.

Frequently asked questions
My child's temperature is 40°C. Should I go to A&E now or wait?+
Not automatically. A temperature around 40°C in a child who is alert, drinking, and perks up between doses is not an emergency by itself. Check when the last dose was given, watch closely over the next hour, and go to your nearest 24-hour A&E if the temperature stays above 40°C and your child seems unwell, or any other concerning signs appear.
Is there a temperature that means go to A&E straight away, no matter what?+
For a baby under 3 months, yes: 38.0°C or above means go to the nearest 24-hour children's emergency, even if your baby seems well. For an older child, there is no single number. Go if the temperature is above 40°C, is not coming down, and your child seems unwell, or if any of the signs above appear. How your child looks and behaves matters more than the number.
How long will we wait at A&E with a feverish child?+
A nurse usually checks your child's temperature, heart rate, and breathing soon after you arrive, as part of triage. The wait to see a doctor and start treatment after that depends on how busy the department is and how urgent other cases are, so it can range from a short wait to considerably longer.
Will my child need a blood test, and what does it check for?+
Not always, it depends on what the doctor finds. If a blood test is needed, it usually checks for signs of bacterial infection (a full blood count and CRP, sometimes a blood culture) or, in Singapore, for dengue (the NS1 antigen test and platelet count). A normal result on the first day does not rule out dengue, so a repeat test a day or two later is common if it's suspected.
How is blood taken from a baby or toddler who can't sit still?+
Usually from a vein in the hand or the inside of the elbow, with a parent helping to hold your child steady rather than the calmer process an older child or adult experiences. Numbing cream applied beforehand can help if there is time to wait for it, and a cuddle or feed afterward usually settles your child quickly. A small bruise at the site is normal.
Can grandparents or a helper come into A&E with us?+
Check when you arrive, but many children's emergency departments limit how many adults can be at the bedside, often to one or two. If several caregivers come along, it is worth deciding beforehand who goes in with your child, since others may need to wait in a separate area.
Should I wait until the thermometer actually shows 41°C before going to A&E?+
No. There is no temperature you need to wait for. If your child's temperature is above 40°C, is not coming down, and your child seems unwell, or any of the signs listed above are present, start heading to A&E then. The doctor will assess your child as a whole on arrival, not just the number on the thermometer.
