Dengue Fever risk in Beirut

Dengue fever is a viral infection spread by Aedes mosquitoes, causing high fever, severe headache, joint pain, rash, and in serious cases, bleeding or shock. There is no specific treatment, so prevention is essential.

Beirut faces a risk score of 58 out of 100 due to several local factors. The Mediterranean climate supports mosquito breeding, especially in summer and early autumn. Water storage in rooftop tanks, flower pots, and construction sites creates ideal breeding grounds. Dense urban neighborhoods with limited waste management allow standing water to accumulate. Warm temperatures and humidity further increase mosquito activity.

Here are practical steps to protect yourself and your family.

First, eliminate standing water around your home. Empty and scrub water containers, flower pot saucers, and drains at least once a week. Cover rooftop and ground-level water tanks tightly.

Second, protect yourself from bites. Use registered insect repellent containing DEET, picaridin, or oil of lemon eucalyptus. Wear long sleeves and pants during early morning and late afternoon when Aedes mosquitoes are most active.

Third, secure your living space. Install or repair window and door screens. Use air conditioning when possible, as mosquitoes avoid cool indoor environments. Use mosquito nets for sleeping, especially if windows are often open.

Fourth, support community efforts. Report blocked drains and stagnant water in public areas to municipal authorities. Participate in neighborhood clean-up campaigns targeting waste and water accumulation.

Fifth, know the warning signs. Seek medical care immediately if you develop sudden high fever with severe headache, pain behind the eyes, or bleeding gums. Inform your doctor about any recent mosquito exposure.
