Dengue Fever risk in Port-au-Prince

Dengue Fever Prevention Guide for Port-au-Prince

Dengue fever is a mosquito-borne viral infection transmitted by Aedes mosquitoes, which bite primarily during daytime hours, especially in early morning and late afternoon. Symptoms include high fever, severe headache, joint and muscle pain, rash, and in severe cases, hemorrhagic complications. Port-au-Prince's risk score of 62/100 reflects ongoing transmission driven by urban density, limited waste management, and seasonal rainfall patterns.

Local Risk Factors in Port-au-Prince

Standing water accumulates rapidly in the city's informal settlements, open drainage channels, and discarded containers. The tropical climate supports year-round mosquito breeding. Inconsistent garbage collection allows tires, plastic containers, and debris to collect rainwater. Overcrowded neighborhoods with limited screened windows increase daytime exposure. Limited access to healthcare facilities in some areas delays treatment.

Prevention Steps

Eliminate breeding sites by emptying, covering, or discarding any container that holds water at least twice weekly. Focus on flower pots, old tires, buckets, and water storage barrels common throughout the city neighborhoods.

Use personal protection during daylight hours. Apply DEET-based repellent on exposed skin. Wear long-sleeved clothing when possible, especially in early morning and late afternoon when Aedes mosquitoes are most active.

Install window and door screens where feasible. Use bed nets treated with insecticide for additional protection, particularly for children and elderly household members.

Secure water storage containers with tight-fitting lids or mesh covers. Add larvicide tablets to water storage tanks that cannot be emptied regularly.

Seek medical attention immediately if fever develops with severe headache, eye pain, or bleeding symptoms. Early detection reduces complications significantly.

Community participation in neighborhood cleanup efforts amplifies individual protection across Port-au-Prince.
