As the year winds down, Singaporean families look forward to a well-deserved break. For children, December means freedom from school, more time outdoors, and exciting plans — from holiday camps and mall playdates to overseas travel. But amidst all the fun, many parents wonder why kids fall sick during holidays in Singapore.
More social interaction, crowded venues, and disrupted routines can make children more vulnerable to falling ill.
At Oaklife Family Clinic, we often see a rise in cases of influenza, Hand, Foot and Mouth Disease (HFMD), stomach flu, and other common viral infections during the year-end break.
In this guide, we explain why children tend to fall sick more often during the holidays in Singapore, and share practical ways to help your child stay healthy so your family can enjoy the season with peace of mind.
Why Kids Fall Sick During Holidays in Singapore: Flu & Viral Spikes
One major reason why kids fall sick during the holidays in Singapore is the seasonal rise in respiratory infections — including influenza, COVID-19, and lesser-known viruses like human metapneumovirus (hMPV). These illnesses tend to spike when children spend more time in crowded spaces such as malls, playgrounds, airports, and enrichment centres.
Children, particularly those under five, are more susceptible to respiratory viruses. While influenza is well known, hMPV is less familiar to many parents but can cause similar symptoms, such as cough, runny nose, wheezing, and even breathing difficulties in younger children. According to Singapore’s Ministry of Health (MOH), there has been a consistent seasonal rise in hMPV cases between October and February each year. In fact, recent data shows an increasing trend in infections — with 163 cases in the week ending 8 June 2024, compared to just 51 cases in early April, as reported by CNA.
Vaccination remains one of the most effective tools in reducing the severity of illness caused by flu viruses. The flu vaccine is safe for children aged six months and up and is updated annually to match circulating strains. In addition to vaccination, parents should encourage frequent handwashing, avoid sharing food and utensils, and consider masking in crowded indoor spaces to reduce the risk of transmission.
Travel Season & New Environments: Another Reason Why Kids Fall Sick During Holidays in Singapore
Whether you’re flying overseas or enjoying a staycation, travel introduces new environmental and viral exposures — another reason why kids often fall sick during school holidays in Singapore. A pre-travel GP visit ensures your child is up to date on important vaccinations and that you are equipped to manage minor medical issues abroad.
It’s wise to pack a small travel health kit that includes children’s paracetamol, antihistamines, motion sickness tablets (if needed), antiseptic cream, and plasters. Be mindful of food hygiene while abroad, and remind your child to drink plenty of water, especially in colder or drier climates. For younger children or those with asthma or allergies, ask your doctor whether additional precautions or medications are necessary.
If you're travelling to areas where respiratory illnesses are rising, your doctor may recommend the COVID-19 booster or other vaccines depending on the destination. Always check with a medical professional at least two weeks before departure.
Holiday Diet & Routine Changes: A Common Cause of Kids Falling Sick in Singapore
Holiday feasting is part of the fun — but it can also contribute to tummy upsets, another frequent concern raised by parents asking why their kids fall sick more easily during holidays in Singapore.
Stomach flu (viral gastroenteritis) is also common during this season, especially with increased exposure to public play areas and restaurants. It typically presents with vomiting, loose stools, fever, and tummy cramps. Most cases are self-limiting, but the key concern is dehydration. Offer small sips of water or oral rehydration fluids frequently, and seek medical attention if your child is lethargic, has sunken eyes, or is passing significantly less urine.
To prevent these issues, ensure your child eats a balanced diet with fruits, vegetables, and fibre-rich options. Bring familiar snacks when travelling, and be mindful of food that’s been left out too long at buffets or parties.
Understanding HFMD and Other Skin Conditions
Hand, Foot and Mouth Disease (HFMD) is another contributor to why kids fall sick more often during the school holidays in Singapore, especially among preschool-aged children. Increased contact in playgrounds, parties, and childcare settings allows the virus to spread quickly.
The illness often begins with a mild fever, followed by painful ulcers in the mouth and a rash or small blisters on the hands, feet, or buttocks. Children may refuse food or become cranky due to the discomfort. While most cases are mild, some children require medical support to manage dehydration or complications.
Other skin issues like heat rash, insect bites, and eczema flares are also common due to increased outdoor activities. Dress your child in breathable clothing, apply child-safe mosquito repellents, and moisturise their skin regularly. If your child develops unusual rashes or their condition worsens, do bring them in for a check-up.

Health Screening Before School Resumes
The end of the year is an ideal time for a health check-up. Many parents book this after noticing their child fell sick several times during the holidays in Singapore and want clarity on immunity, nutrition, or developmental concerns.
At Oaklife Family Clinic, we provide child-friendly screenings and can advise on age-appropriate milestones, behavioural observations, and nutritional guidance. Many parents also take this opportunity to discuss concerns about picky eating, frequent illnesses, or speech development.
Booking this check-up before the school year starts avoids the January rush and gives you time to follow up if needed.
Keeping Kids Healthy, Happy, and Rested
Amid the excitement of the holidays, it’s easy for children to become overstimulated or overtired. Late bedtimes, excessive screen time, and packed schedules can wear them down — affecting their immunity and behaviour.
Try to maintain a consistent sleep routine and offer breaks between activities. Encourage outdoor play balanced with quiet downtime. A little planning goes a long way in creating a holiday experience that is both enriching and restorative for your child.

Frequently Asked Questions (FAQ)
Q. What are the most common illnesses during the December holidays in Singapore?
A. Common illnesses among children during the year-end break include the flu, hand, foot and mouth disease (HFMD), viral gastroenteritis (stomach flu), upper respiratory tract infections, and rashes caused by heat, insect bites or viruses. Emerging infections like human metapneumovirus (hMPV) also tend to increase during this period.
Q. Should my child get the flu vaccine before travelling or attending holiday camps?
A. Yes. The flu vaccine is recommended yearly for all children above six months of age, especially before the holiday season when exposure increases. It helps reduce the risk of falling seriously ill and prevents community spread in schools, camps, and public spaces.
Q. My child is coughing but doesn’t have a fever. Should I still see a doctor?
A. If the cough is persistent, worsens at night, or is accompanied by wheezing or breathlessness, it’s advisable to see a doctor — even without a fever. Viruses like hMPV can present this way and may lead to complications, especially in younger children.
Q. What should I pack in a travel health kit for my child?
A. A basic child travel kit should include children’s paracetamol, antihistamines, motion sickness medication (if needed), oral rehydration salts, insect repellent, antiseptic cream, plasters, and any prescription medications your child is already taking.
Q. Is it too late to catch up on my child’s vaccinations in December?
A. Not at all. December is a great time to catch up on missed immunisations or do pre-school/primary school boosters before the January term. Your GP can advise based on the National Childhood Immunisation Schedule in Singapore.
Q. Can I use home remedies for stomach flu or HFMD?
A. Most cases of viral stomach flu and HFMD can be managed at home with rest, fluids, and symptom relief. However, seek medical attention if your child is not drinking, is very sleepy, has worsening symptoms, or is under 6 months old. Avoid giving over-the-counter medication without doctor guidance.
