Rashes Are Extremely Common in Children — Especially in Singapore
If your child suddenly breaks out in red spots or itchy patches, it’s completely understandable to worry. Parents often ask: Is this serious? Is it contagious? Should I bring my child to the doctor now, or can we wait and see?
In tropical climates like Singapore, rashes are among the top 10 most common reasons for paediatric clinic visits.
According to research:
Up to 30% of outpatient visits for infants and toddlers involve skin-related concerns
Heat rash and viral exanthems are especially common during hot and humid months, or in children attending childcare
Eczema affects around 1 in 5 Singaporean children, with many cases starting before the age of 5
HFMD cases have been rising, with the MOH reporting a daily average of 61 cases between Apr 27 to May 3, 2024 – the highest daily average since 2022. In comparison, daily averages in 2023 and early 2024 remained below 50 cases
These numbers reflect how common — and often confusing — rashes can be for parents navigating early childhood in Singapore.
Dr Daniel, Family Physician at Oaklife Family Clinic, shares: “We see rashes daily at our clinic — it’s part of growing up in Singapore’s climate and close-contact preschool environments. Most are harmless, but it helps to know what’s normal and when to check in.”
Common Types of Rashes in Singapore Children
Let’s look at some of the most frequently seen rashes at Oaklife Family Clinic:
1. Viral Rashes
These often appear during or after a viral illness. They may look like flat pink or red spots with small bumps and are usually not itchy.
Examples:
Roseola (fever followed by rash)
Viral exanthems (from flu or cold viruses)
HFMD (Hand, Foot and Mouth Disease): painful blisters on hands, feet, and mouth
2. Heat Rash (Prickly Heat)
Common in Singapore’s humid climate, heat rash looks like tiny red or clear bumps — often found on the neck, chest, or diaper area. It occurs when sweat ducts get blocked.
3. Eczema (Atopic Dermatitis)
A chronic, itchy skin condition that typically appears behind the knees, elbows, or on the face. It flares with triggers like heat, dust, soaps, or allergens.
Dr Jacquelyn Melody shares: “My own sons had eczema as toddlers. Consistent moisturising and trigger avoidance made a big difference in keeping flare-ups under control."
4. Allergic Rashes (Hives)
Hives appear as red, raised, itchy welts that can come and go within hours. They may be triggered by:
Certain foods
Medications
Insect bites or infections
While many cases are mild, persistent or recurrent hives should be reviewed by a doctor.
5. Chickenpox (Varicella)
A highly contagious viral illness, chickenpox begins with fever, then progresses to an itchy rash of red spots that turn into fluid-filled blisters and eventually scab over.
The rash can spread to the whole body, including the scalp, eyelids, and inside the mouth. Vaccinated children may still get mild chickenpox.
Dr Daniel Lim notes: “If your child has fever with a blister-like rash, isolate early and consult a doctor, especially if there is a newborn or pregnant family member at home.”
6. Diaper Rash (Nappy Rash)
Diaper rash is caused by prolonged contact with urine or stool and appears as red, inflamed skin in the diaper area.
Helpful tips include:
Using fragrance-free wipes
Applying barrier creams such as zinc oxide
Allowing diaper-free time when possible
See a doctor if the rash becomes bright red, bleeds, or spreads, as this may indicate fungal or bacterial infection.
7. White Spots or Bumps on Skin
White patches or bumps may be caused by:
Fungal infections (common in skin folds)
Molluscum contagiosum, a viral infection causing small dome-shaped bumps
Pityriasis alba, light patches often seen in eczema-prone children
These are usually harmless but may last weeks to months. A doctor can confirm the diagnosis and advise if treatment is needed.
8. Bacterial Skin Infections
Bacterial infections like impetigo and cellulitis are more serious and require antibiotics. They are common among toddlers and preschoolers, especially those with eczema or cuts on the skin.
Impetigo: Honey-coloured crusty blisters, especially around the mouth and nose
Cellulitis: Red, swollen, painful skin that may be warm to touch; sometimes accompanied by fever
Boils or abscesses: Pus-filled lumps that are tender and may need drainage
Dr Daniel shares: “Rapidly spreading rashes, swelling, pain, or fever can signal bacterial infection. These should not be delayed.”
When Should You Worry About a Rash?
Seek immediate medical attention if your child has:
High fever with rash
Rapidly spreading or worsening rash
Blisters, ulcers, or open sores
Swelling of the lips, tongue, or eyes
Purple spots that do not fade when pressed
Lethargy, poor feeding, or breathing difficulty
If you’re unsure whether your child’s rash could be HFMD, our doctors can examine and confirm it clinically.
A Real Parent’s Story: Red Dots After Preschool
“My daughter came home from preschool with red bumps on her arms and legs. I was convinced it was HFMD again.
Dr Daniel at Oaklife reassured us it was a mild post-viral rash, very common and not serious. With moisturiser and keeping her cool, the rash cleared in a few days.”
How to Care for Mild Rashes at Home
For mild, non-urgent rashes:
Keep your child cool in loose cotton clothing
Use gentle, fragrance-free cleansers
Moisturise 2 to 3 times daily
Avoid hot baths and perfumed products
Keep nails short to reduce scratching
Avoid using leftover medicated creams unless prescribed, as some treatments may worsen the rash.

Allergic reactions (e.g. to food or insect bites)
Q: How can I tell if a rash is caused by HFMD?
A: HFMD rashes typically appear as small red spots or blisters on the hands, feet, mouth, and sometimes the buttocks. If your child also has fever, sore throat, or refuses to eat, it could be HFMD. Book a consult to confirm.

A: Not always. If your child is:
Eating and playing normally

The rash is mild and not spreading
You can often monitor it at home. But see a doctor if there are blisters, fever, swelling, or purple spots.
Q: Can teething cause rashes?
A: Teething itself doesn’t cause body rashes, but drooling can lead to irritation or rashes around the mouth and chin. These are usually harmless and improve with moisturising and wiping gently.
Q: Is eczema contagious?
A: No. Eczema is not contagious and cannot be spread between children.
