Quezon City Dengue Cases Increase 300%

The Philippines's most populous city, Quezon City, has been a well-known hub for business activities and tourism as the city of stars in Asia. Unfortunately, it has become a hot spot for the mosquito-transmitted Dengue virus in 2025.

From January to March 9, 2025, the City Epidemiology and Surveillance Division of Quezon City recorded 3,608 Dengue cases and 12 related fatalities, a significant (300%) increase from 2024.

Overall, Quezon City has about 3 million residents and is 12 miles northeast of the capital city of Manila. Most of the Dengue cases have been reported in District #2 this year.

Previously, the City's Health Department declared a Dengue outbreak.

“Our declaration of a dengue outbreak ensures that we are on top of the situation, and we are doing everything we can to protect our residents from this deadly disease, especially our children,” Mayor Joy Belmonte said in a February 27, 2025, press release.

Recently, the Global Dengue Travel Health Advisory, updated by the U.S. CDC, highlighted the Philippines, saying that this disease is a year-round risk in many parts of the world, including the United States.

As of March 2025, there have been 893 Dengue cases reported in 23 U.S. jurisdictions this year, led by Florida.

While Dengue vaccines are no longer available in the U.S., the CDC recommends discussing immunization options with a travel vaccine expert.

Before visiting the Philippines, the CDC also suggests that future travelers discuss chikungunya, cholera, Japanese encephalitis, and malaria prevention options. And under International Health Regulations, proof of vaccination against yellow fever is required for certain travelers arriving from countries with a risk of yellow fever transmission in 2025.
