With cases on the rise and new isolation measures in place, understanding the spread of measles in Singapore is vital for protecting vulnerable infants and the wider community.
When someone develops a fever and rash, measles is not quite the first illness that comes to mind. However, the current rise in measles infections in Singapore has brought this highly contagious disease back into the spotlight.
January of this year alone identified 11 cases of measles – the same number of cases seen in the whole of 2024. More recently, the country recorded the first measles case involving a child attending preschool. At 11 months of age, she is the fifth case involving an infant less than a year old in 2026.
The resurgence of measles in Singapore has been ringing alarm bells, with health experts urging renewed awareness regarding the disease.
What Is Measles?
Measles, otherwise known as rubeola, is a disease caused by the measles virus, and spreads through airborne droplets. It is highly contagious; if someone with measles coughs or sneezes, the disease can remain infectious in the air or on surfaces for up to two hours.
When the virus enters your body, it infects the respiratory tract first. It then spreads to other parts of your body via the bloodstream.
Anyone can develop complications from measles. The risk is highest among:
- Infants too young to be vaccinated.
- Non-immune pregnant women.
- Individuals with compromised immune systems.
The Signs and Symptoms of Measles
Symptoms typically begin 8 to 14 days after exposure, and can include:
- Flu symptoms like runny nose, cough or sore throat
- High fever
- Red and sore eyes
- Koplik’s spots, or red spots with white centres in your mouth
- Headaches or muscle pain
- Rashes
- Digestive issues like diarrhoea and vomiting
These signs do not appear all at the same time.
It can start with the more flu-like symptoms. Koplik’s spots might appear a couple of days later, then fade as the rash – the most distinctive feature of this disease – develops.
The rashes typically start as patches on your face. It then spreads downwards to your neck and the rest of your body. A high fever may also come about alongside the rashes.
Possible Complications of Measles
While most people who catch this disease can experience a full recovery, it can also lead to a variety of complications, ranging from mild to potentially fatal.
Some common problems include ear infections and dehydration. However, more serious complications include:
- Pneumonia, either from the measles itself or through a secondary infection.
- Encephalitis, or the inflammation or infection of the brain.
- A heightened risk of severe infections post-recovery.
- Pregnancy complications.
Can Vaccination Prevent Measles?
Vaccination is the most effective form of prevention against measles. One dose of the vaccine, which is called the MMR, is 93% effective, while two doses raise this efficacy to 97%. Most gain long-term protection after the second dose.
In Singapore, under the Infectious Diseases Act, vaccinating against measles is compulsory for all children aged 12 and under. Furthermore, 99% of adult residents have immunity against this disease. This has pushed herd immunity in the country to over 95%.
If you are unsure of whether you have been vaccinated, check your vaccination records, or visit a healthcare provider to seek confirmation through a blood test.
Taking Precautions
Should you come into contact with someone who has measles, no special precautions are necessary if you are vaccinated. However, those who are unvaccinated should consult a doctor.
A new measure Singapore is taking is mandatory isolation for confirmed measles cases; the individuals are under quarantine until they are no longer infectious. If the case does not require hospitalisation, they can isolate at home, with random video calls being conducted to check in on their situation.
Close contacts who are unvaccinated will also be placed on home quarantine, which can last up to 21 days.
There is no specific cure if you happen to develop the measles, so recovery will include plenty of rest. Drink more water to prevent dehydration, consume more fruits and vegetables to support your immune system, and consider vitamin A supplements to restore depleted vitamin A levels and prevent blindness. You can also take ibuprofen or paracetamol to ease the pain, especially if you have developed a fever.
Be sure to practice good hygiene as well, to prevent a further spread of the disease.
Check Your Vaccinations
And if you are a parent or guardian, ensure your child’s MMR vaccinations are up to date, and be on the lookout for symptoms, especially after community exposure or travelling.
The number of measles cases have also seen a spike globally, which means that it is possible to catch it from someone else while overseas, and transmit it locally when you are back in Singapore.
“The re-emergence of measles elsewhere in the world due to lowered vaccination rates should serve as (an) impetus for Singapore to maintain its high MMR vaccination coverage,” said Professor Ooi Eng Eong, from the emerging infectious diseases programme at Duke-NUS Medical School, in CNA.
“As long as the vaccination rate is sustained at greater than 95 per cent of our children, sporadic cases of measles may occur, but we will remain protected against a measles outbreak.”
