Dengue Fever risk in Port Moresby

Dengue Fever in Port Moresby: Prevention Guide

Dengue fever is a mosquito-borne viral infection that causes high fever, severe headache, joint and muscle pain, and rash. In serious cases, it can lead to dengue hemorrhagic fever, which can be life-threatening. There is no specific treatment, so prevention is critical.

Why Port Moresby is at risk: The city's warm, humid tropical climate combined with frequent rainfall creates ideal breeding conditions for Aedes aegypti mosquitoes, the primary carrier of dengue. Rapid urbanization, inadequate drainage systems, and widespread water storage in open containers around households provide countless breeding sites. The Aedes mosquito bites mostly during early morning and late afternoon hours, making daily exposure a real concern for residents and workers across the city.

Your prevention steps:

Eliminate standing water around your home and workplace. Empty, scrub, and cover all water storage containers, buckets, tires, plant saucers, and any item that collects rainwater at least once a week. Mosquitoes can breed in as little as a bottle cap of water.

Use personal protection consistently. Apply insect repellent containing DEET or picaridin to exposed skin every morning and late afternoon. Wear long sleeves and trousers when possible, especially if working outdoors or near stagnant water. Sleep under insecticide-treated bed nets or use window screens to reduce indoor mosquito contact.

Treat your living and working spaces. Use mosquito coils, plug-in repellent devices, or residual indoor spraying in high-risk areas. Report large collections of stagnant water in your neighborhood to local health authorities, as community-level cleanup is essential in a city where drainage infrastructure is limited.

Seek medical attention immediately if you develop sudden high fever, severe pain behind the eyes, or unusual bleeding. Early hospital evaluation can distinguish dengue from other fevers and prevent dangerous complications. Avoid aspirin and ibuprofen, as these increase bleeding risk; use paracetamol for pain and fever instead.

Stay informed through the National Department of Health advisories, especially during the wet season when dengue cases typically surge across the National Capital District.
