The National Capital Region (NCR) logged the highest case of measles-rubella (MR) with 295 cases, according to the latest data by the Department of Health (DOH).
The DOH also recorded 1,185 MR cases nationwide, which is 27 percent higher than the 930 cases in the same period last year.
Among the top regions with the most cases following NCR are Central Luzon with 150 cases and Calabarzon with 144 cases.
According to the DOH, most of those affected are still unvaccinated (802 or 68 percent).
DOH Secretary Ted Herbosa said they continue to monitor measles cases in the country in conjunction with an intensified campaign to vaccinate all Filipino children against this disease.
"In any areas where many children are unvaccinated, the number of cases is also higher," Herbosa noted.
"Parents, come and get your children vaccinated against measles," he added.
The Health chief reminded that routine immunization continues in all regions of the country for children aged zero to 12 months to protect them against various diseases, including measles.
Under this, the first dose of the measles vaccine is given at nine months, while the second dose is at one year.
The DOH has also intensified the widespread catch-up immunization currently underway in several regions of the country.
Catch-up immunization is for children aged one year to four who have not completed their routine immunization within the prescribed period.
In collaboration with local government units, barangay health workers, and other sectors, the same campaign aims to reach all unvaccinated children, according to the DOH.
The DOH also encouraged parents and guardians to ensure their children are vaccinated to protect them from serious complications caused by measles.
The Health department likewise urged them to contact the nearest health center for the vaccination schedule.
