The Health Bureau (SSM) issued a warning yesterday stating that considering the significant increase in measles cases in neighbouring regions, residents planning to travel abroad are urged to ensure that they have completed their measles vaccination before departure.
According to the statement, individuals without immunity should receive the vaccine at least two weeks in advance. Unvaccinated children and pregnant women without immunity are advised to avoid travelling to areas where measles is circulating, the statement said.
The bureau noted in the statement that measles is highly contagious, adding that the World Health Organisation (WHO) indicates that each infected person can lead to up to 18 secondary infections. It also said that the incubation period typically ranges from seven to 18 days but can last up to 21 days.
Infected individuals are contagious from four days before to four days after the rash appears. Symptoms include fever –above 38°C, Koplik’s spots* inside the mouth, a generalised maculopapular rash**, conjunctivitis, cough, and runny nose.
The bureau emphasised that vaccination is the most effective way to prevent measles.
Individuals born in 1970 or later who lack immunity should ensure they have completed their vaccination before travelling, according to the statement, while individuals under the age of 18 need to have received at least two doses of a measles-containing vaccine – routinely administered at 12 and 18 months of age.
Individuals aged 18 or older should receive at least one dose, with high-risk groups such as healthcare workers, domestic helpers, and childcare facility staff being recommended to receive two doses, the statement said.
The statement also said that residents and non-residents staying in Macau for a long time in need of vaccination can make an appointment at any local health centre or enquire directly with private healthcare providers.
The bureau reminded the public that if symptoms such as fever or rash develop during travel or after returning to Macau, they should seek medical attention promptly and inform the healthcare provider of their travel history.
* Koplik’s spots are tiny, irregular-shaped spots that appear inside the mouth and are considered an early, diagnostic sign of measles (rubeola). - DeepSeek
**A maculopapular rash appears as a mix of flat, red patches and small, raised bumps. Because the two types often blend together, the rash frequently looks like pinkish-red spots that are slightly raised and may merge into each other. – DeepSeek
