Climate Change Linked to Surge in Dengue Mosquitoes, Health Expert Warns

According to Dr. Kim Patrick Tejano, a Medical Officer IV at the Department of Health Disease Prevention and Control Bureau, climate change is significantly impacting Aedes mosquitoes, known carriers of dengue fever. He emphasized that the mosquitoes’ prolonged survival and quicker maturation into adults are particularly affected.

Tejano pointed out that repeated flooding could be a key factor contributing to the increase in mosquito populations. He explained that the cycle of flooding followed by dry spells and subsequent rainfall triggers the hatching of Aedes mosquito eggs, accelerating their growth and maturation.

Studies have indicated that Aedes mosquitoes thrive in fluctuating conditions, such as those caused by repeated flooding and drying followed by submersion in water again.

Tejano highlighted that dengue cases tend to rise during the rainy season due to the abundance of breeding sites, such as unused tires and containers collecting rainwater.

To address the spread of dengue fever, Tejano urged communities to adhere to the “4S strategy,” which involves search and destroy activities, ensuring self-protection, seeking early consultation, and supporting fogging and spraying efforts.

As of June 8, the country has reported 74,322 cases of dengue fever.

The Department of Health clarified that there is currently no specific treatment for dengue fever, with supportive care being the main approach to manage symptoms until recovery.

Experts have also emphasized that plants like tawa-tawa, guava, and siling labuyo have not been scientifically proven as cures for dengue fever.

Common symptoms of dengue fever include fever lasting for two to seven days, pain behind the eyes, headache, skin rash, nausea and vomiting, stomachache, and body pain.

Patients are advised to consult healthcare providers, stay hydrated, and rest to aid recovery during treatment.
