This to avoid health complications, as well as to contain further outbreak, advised Sarawak Health director Dr Jamilah Hashim.
As of Monday, a total of 48 positive cases had been detected.
Of the figure, 19 victims caught measles from the outbreak, while 29 others were sporadic (single cases).
The outbreak also affected 20 children below seven years old, she added.
A kindergarten in Bintulu was forced to close for seven days last week because of the measles outbreak, which also affected eight residential areas including a living quarters of foreign workers of a sawmill.
The state Health Department took immediate action to contain the outbreak, she continued.
“We have carried out strict monitoring and preventive measures to curb further outbreak of the disease from identified areas, which is very important especially to protect infants below six months, immunocompromised patients and senior citizens.
“We conducted door-to-door and work place detection, checked vaccination status of children at the affected areas, as well as identified those yet to receive their shots,” Dr Jamilah said in a statement yesterday.
Of the 48 infected persons, 12 children had yet to receive their measles vaccination as they are below six months old.
Six other victims had never received their vaccination, while the immunisation status of the remaining 25 was unknown.
To date, the department has checked 22,414 people, including administering measles vaccination on 675 individuals in the affected areas.
“Measles can be prevented with vaccination.
“Under the national children immunisation programme, two doses of measles-mumps-rubella shots will be given to babies aged nine months and 12 months.
“Parents are advised to ensure their children have received these shots according to the immunisation schedule set by the Health Ministry. Children who missed their shots must be vaccinated at the health clinic,” Dr Jamilah said.
She urged those with measles to wear a face mask to help prevent the cough they have from spreading.
The state Health Department is actively carrying out awareness programmes on measles and the need to seek vaccination for children below seven years old at the affected areas and surrounding vicinity.
