With the rainy season upon us, be vigilant about dengue prevention.
Dengue fever is a viral infection transmitted by female Aedes aegypti mosquitoes, which thrive in tropical climates and breed in stagnant water. Cases typically rise during the rainy months, when frequent rainfall creates more breeding sites around homes and communities.
There is still no specific antiviral cure for dengue, so early consultation, proper hydration, and close monitoring are crucial to prevent severe complications. Dengue remains a major public health concern in the Philippines, where thousands of infections are reported every year.
The good news is that the country has seen a significant decline in cases this year. According to the Department of Health (DOH), dengue cases nationwide from January to May 2026 are 56% lower than during the same period in 2025. Health officials attribute the decrease to sustained community clean-up efforts and the continued promotion of anti-dengue campaigns.
Even with this encouraging trend, health authorities warn that the risk increases during the rainy season. Preventing mosquito bites and eliminating breeding sites remain the most effective ways to protect yourself.
Recognizing the Symptoms
Symptoms usually appear 3 to 14 days after infection and may include:
• High fever• Severe headache, especially behind the eyes• Muscle and joint pain • Skin rash, which often appears as the fever subsides
Most cases resolve within 2 to 7 days. However, some may progress to severe dengue, formerly known as dengue hemorrhagic fever, which can be life-threatening and requires immediate medical attention.
What To Do
• Drink plenty of fluids
• Get adequate rest• Use paracetamol for fever and pain relief• Avoid NSAIDs such as aspirin and ibuprofen to avoid risk of bleeding
Department of Health’s 4S Strategy
• Search and destroy mosquito breeding grounds by eliminating stagnant water and water-holding containers.
• Self-protection through the use of insect repellent, mosquito screens and protective clothing
• Seek early consultation if symptoms develop.
• Support spraying or fogging in hotspot areas when recommended by health authorities.
Early detection, proper medical care and preventive measures remain the best defenses against dengue fever.
The DOH further reminds the public to stay alert against W.I.L.D. illnesses during the rainy season: Waterborne diseases, Influenza, Leptospirosis, and Dengue. Protect yourself by wearing boots and rain gear in flood-prone areas, drinking safe water, eliminating mosquito-breeding sites, and following the DOH's 4S dengue prevention measures.
