On February 6, 2019, the Philippines Department of Health declared a measles outbreak in Manila, Philippines with over 400 cases and five confirmed deaths from January 1, 2019. One day later, health officials declared that the outbreak spread to other surrounding regions. As of February 11, 2019, the number of measles cases in the Philippines has risen to 4,300 people with 70 deaths. The Department of Health estimated that about 2.4 million children have not yet received the measles vaccine. Low vaccination rates may be due to the lack of trust in vaccination programs in the Philippines following a Dengue fever vaccination controversy in 2017; the Department of Health suspended the Dengue fever vaccine distribution when the vaccine manufacturer found that the Dengue vaccine did more harm than good.
The US Centers for Disease Control and Prevention recommends potential travelers to the Philippines to be fully vaccinated with the MMR (measles, mumps, rubella) vaccine before travel. Infants 6-11 months should have one MMR dose and people older than one year of age should have two MMR doses separated by at least 28 days.
