A Common Worry Among Parents
One father came rushing into our clinic with his 18-month-old son in his arms, saying, “The thermometer said 39.2°C — is it dengue?” The child, however, was smiling, playing with the receptionist’s pen, and asking for snacks. While it’s natural to panic when you see a high number on the thermometer, the child’s behaviour often tells a more important story. This scenario is something we see all the time — and learning what to observe beyond the number can empower parents to respond more calmly.
It’s completely normal for parents to turn to the internet when their child has a fever — wondering things like “Is this too high?”, “What fever medicine can I give to my child?”, or “Should I bring them to the clinic?” These are real concerns we hear every day, and in this article, we aim to provide clear, practical advice that’s relevant for families in Singapore.
Fever is one of the most common reasons parents bring their children to Oaklife Family Clinic. It’s also one of the most anxiety-inducing. As parents, it’s natural to associate high temperatures with danger. But not all fevers are bad. In fact, fever is the body’s natural immune response — a sign that the body is fighting off an infection. The key is to know when to observe and when to act.
“We often remind parents that fever itself is not the illness — it’s a signal,” says Dr Daniel Lim, Senior Physician at Oaklife Family Clinic. “What matters most is how the child is behaving. If they’re active and drinking, you may not need to worry.”
What Is Considered a Fever in Children?
In Singapore, fever is one of the top reasons for paediatric consultations. Most cases are viral in origin and resolve without complications.
A child is generally considered to have a fever when their temperature is:
Above 37.5°C (measured orally)
Above 38°C (measured rectally)
Low-grade fevers (up to 38.5°C) are usually linked to common viral infections and don’t require medication unless the child is uncomfortable.
Common Causes of Children's Fever in Singapore
Children's fever is often a symptom, not a standalone illness. The vast majority of cases are due to viral infections, which the immune system can manage without antibiotics.
Typical causes include:
Colds and flu
Roseola
HFMD (Hand, Foot, and Mouth Disease)Ear infections or tonsillitis
Mild post-vaccination reactionsTeething (may raise temperature slightly, but not above 38°C)
These illnesses usually resolve with rest, fluids, and supportive care.
When You Can Monitor at Home
If your child is eating, drinking, and behaving normally, it’s usually safe to manage the fever at home — even if the thermometer shows a high number.
You can monitor at home if:
Your child is alert and responsive
They are hydrated (passing urine, no dry lips)
The fever is under 38.5°C and not causing discomfort
“Parents can focus on comfort rather than chasing the number,” says Dr Jacquelyn Melody, Senior Physician at Oaklife. “Medication helps with discomfort, but a playful child with a mild fever is often not in danger.”
When to Seek Medical Attention
Bring your child to the clinic if:
The fever lasts more than 3 days
Your child is under 3 months old and has a temperature over 38°C
They show signs of lethargy, irritability, or poor feeding
They refuse fluids or don’t urinate for 6–8 hours
The fever spikes above 40°C
There are additional symptoms like rashes, vomiting, or stiff neck
Managing Fever at Home Safely
When managing fever at home, focus on comfort and hydration.
Use paracetamol or ibuprofen if your child is uncomfortable
Dress them in light clothing
Keep the room cool and well-ventilated
Offer frequent fluids, including water or soup
Avoid outdated practices such as cold sponge baths or alternating medications without medical advice.
Fever Facts vs Myths
Myth: A high fever always means a serious illness.
Fact: A child with 39.5°C who is active may be better off than a drowsy child with 38°C.
Myth: Teething causes high fever.
Fact: Teething may raise temperature slightly but rarely over 38°C.
Myth: You must “bring down” every fever.
Fact: Fever is a useful immune response — treatment is only needed for comfort.
Myth: Rubbing alcohol or cold water sponging is best.
Fact: These can cause shock; room temperature sponging is safer if advised.
“We sometimes see well-meaning caregivers overmedicating or using outdated methods out of fear,” says Dr Jacquelyn Melody. “Education is key — fever is often a friend, not a threat.”
What If My Child Keeps Falling Sick?
It’s common for toddlers to have 8–12 viral infections a year, especially those in childcare. Frequent illness doesn’t mean weak immunity — it’s part of immune system development.

Don’t Fear the Fever — Understand It
Fever is not dangerous by default — it’s a sign that the immune system is working. What matters most is your child’s behaviour, hydration, and overall condition. Monitor the right signs, offer comfort, and don’t hesitate to seek help if unsure.

Frequently Asked Questions (FAQ)
Q. What temperature is considered a fever in Singapore for toddlers?
A. A fever is generally considered when the temperature is above 37.5°C (oral) or above 38°C (rectal). For toddlers, any reading above this range warrants monitoring, especially if accompanied by other symptoms like fatigue or poor appetite.
Q. When should I bring my child to the doctor for a fever?
A. Bring your child to the clinic if the fever lasts more than 3 days, spikes above 40°C, or if your child is under 3 months old with any fever. Other warning signs include lethargy, dehydration, or a persistent rash.
Q. Can teething cause fever?
A. Teething may cause a slight rise in temperature, but rarely above 38°C. If your child has a high fever, it’s more likely due to a viral infection than teething.
Q. Should I give fever medicine right away?
A. If your child is uncomfortable, you can give paracetamol or ibuprofen at the correct dose. However, if they’re alert and playful, fever medicine is not always necessary. It’s more about comfort than lowering the number.
Q. How many viral fevers are “too many”?
A. If your child is attending childcare or preschool, getting sick 8–12 times a year is considered normal. Their immune system is still learning to fight off viruses. Frequent mild fevers are not usually a cause for concern.
Q. What are signs of dehydration in a child with fever?
A. Watch out for dry lips, no tears when crying, reduced urination, sunken eyes, or persistent sleepiness. These may indicate dehydration and require medical attention.
