Malaria risk in Port Moresby

MALARIA PREVENTION GUIDE - PORT MORESBY

Malaria is a life-threatening disease caused by parasites transmitted through the bite of infected female Anopheles mosquitoes. In Papua New Guinea, including Port Moresby, malaria risk remains significant, with a risk score of 61/100 indicating moderate to high exposure danger. The tropical climate, urban drainage issues, and standing water from poor sanitation create ideal mosquito breeding grounds even in the capital city.

SPECIFIC LOCAL RISK FACTORS IN PORT MORESBY

The city generates high transmission risk due to inadequate drainage systems, open water containers, and marshy areas around settlements. Wet season increases mosquito breeding. Many residents live in housing without proper screens or nets. Local mosquito species are adapted to urban environments and bite primarily from dusk to dawn.

ACTIONABLE PREVENTION STEPS

1. Sleep under long-lasting insecticidal nets (LLINs) every night, ensuring no gaps or holes. Treat nets properly and replace them every three years.

2. Apply DEET-based repellent on exposed skin from dusk through dawn when Anopheles mosquitoes are most active.

3. Eliminate standing water around your home. Cover water tanks, clear blocked drains, and dispose of discarded containers weekly.

4. Wear long sleeves and trousers during evening and night hours, especially in areas near drains or marshland.

5. Seek immediate medical attention within 24 hours of fever onset. Carry rapid diagnostic tests if traveling to remote areas. Do not self-treat without confirmation.

For pregnant women and children under five, consult local health facilities for preventive treatment programs.
