Measles is on the rise in Singapore, with the Ministry of Health reporting 17 cases in two locations just last week. One group was located in a residential home for those with intellectual disabilities, while the other group of cases was in a foreign worker dormitory. There have been 116 confirmed cases so far this year, but MOH says it hasn’t spread into the community.
That’s not all – the number of measles cases worldwide quadrupled in the first three months of the year, compared with the same period last year. In the United States, for instance, the number of measles cases crossed over 1,000. It’s the largest outbreak since 1992, according an article in Slate magazine.
What is measles?
Measles, which affects the respiratory system and often results in a skin rash, is highly transmissible among people who have not been vaccinated.
An infected person can transmit the virus to about 15 to 20 others who are not immune to measles, said Professor Leo Yee Sin, executive director of the National Centre for Infectious Diseases.
“Hence, we need more than 90 per cent of people in the community with immunity against measles in order to break the chain of transmission,” she adds, encouraging people to get vaccinated. In the US, many blame the groups of anti-vaccination parents (known as “anti-vaxxers”) for the spike in cases in a developed country.
The first dose of the MMR vaccination should be given at 12 months and the second dose at 15 to 18 months. If your kid has missed one or both doses of measles vaccination, get them vaccinated immediately, the Health Ministry advises.
Other members in the family who haven’t been vaccinated against measles are advised to do so, especially if there is a baby being cared for at home.

Why the spike in measles worldwide
The World Health Organisation (WHO), which announced the global rise in measles cases on April 15, 2019, said this follows consecutive increases over the past two years. “While this data is provisional and not yet complete, it indicates a clear trend. Many countries are in the midst of sizeable measles outbreaks, with all regions of the world experiencing sustained rises in cases,” the WHO adds.
Dr Nicholas Chew, an infectious disease specialist at Farrer Park Hospital, said the problem lies with significant populations around the world not getting vaccinated. “Effective vaccination programmes are severely hindered by factors including complacency, misinformation about vaccine efficacy and safety, anti-vaccine scare-mongering, poverty, war and conflict,” he adds.
Safe and effective vaccine
Measles is preventable through two doses of a safe and effective vaccine, says Professor Michael Merson, director of the SingHealth Duke-NUS Global Health Institute.
The vaccine also mitigates the risk of virus-induced neurological complications and death, which – although rare – can occur up to 20 years after the primary infection clears, noted Assistant Professor Danielle Elizabeth Anderson from the Emerging Infectious Diseases Programme at Duke-NUS Medical School.
In Singapore, the vaccination is compulsory by law for all children living here, while the National Adult Immunisation Schedule also advises people who have not been vaccinated to do so.
If you’re worried about the side effects of the MMR vaccine (Measles, Mumps and Rubella), don’t be. A study that claimed to link autism to the MMR vaccine has been discredited – and the study itself has been redacted.
Why Singapore is at risk for measles outbreaks
While the risk of a measles outbreak here is low because of the population’s high vaccination rates, the country remains vulnerable due to its position as an international travel hub and the cosmopolitan make-up of its residents, says Dr Chew.
The MOH said it will continue to monitor the situation closely and has alerted general practitioners to look out for cases of measles, especially among patients who have recently travelled overseas or who have not been vaccinated, and to notify the ministry promptly.
It advises Singaporeans to get vaccinated if they are travelling to areas with measles outbreaks, observe good personal hygiene at all times, and seek medical attention promptly if they feel unwell.
