The immunity rate to measles among domestic workers from the Philippines is about 94% – almost the same level as Macau residents aged 20 years or older, officials have said.
The Health Bureau revealed the results of sample tests on Monday, saying “the level of immunity against measles among non-resident workers and the citizens of Macau is ideal,” Macao Daily Post reported.
After an outbreak of measles in the city, the government invited Filipino domestic workers to take part in a sampling test in a bid to better understand their level of immunity in regard to the disease.
Some 107 Filipina domestic workers participated in the free blood test between April 1 and 6. This included 50 workers aged under 40, while the rest were 40 or older.
The results showed that about 87% of the sample participants aged from 20 to 39 had received vaccinations against measles, while 100% of those aged 40 or older were also immune to the disease.
The proportion of the Macau residents that are immune to measles is close to 100% for all age groups above the age of 20.
According to the Center for Disease Control and Prevention, four Filipino nationals were infected with measles in Macau – and three of them had imported the disease. The other case related to the spread of measles in Macau.
