Zika Virus risk in Recife

Zika Virus Prevention Guide - Recife, Brazil

Risk Score: 69/100 (Elevated)

Zika virus is a mosquito-borne illness transmitted primarily through the bite of infected Aedes aegypti mosquitoes. While many infected people experience mild symptoms or none at all, Zika poses serious risks during pregnancy due to its link to microcephaly and other birth defects. There is currently no vaccine or specific treatment available.

Recife presents elevated risk due to its tropical climate, high humidity, and dense urban population. The city's proximity to standing water in informal settlements creates ideal breeding conditions for Aedes mosquitoes. Year-round warm temperatures allow mosquito populations to thrive without seasonal interruption. Heavy rainfall periods from March through July significantly increase breeding sites. Limited sanitation infrastructure in many neighborhoods compounds these challenges.

Prevention Steps

Eliminate standing water around your home weekly. Empty, scrub, and cover any containers that collect water including flower pots, buckets, tires, and pet dishes. Mosquitoes lay eggs in very small amounts of water.

Use EPA-registered insect repellent containing DEET, picaridin, or oil of lemon eucalyptus on exposed skin. Reapply as directed, especially during peak mosquito hours from dawn through mid-morning and late afternoon.

Wear long sleeves, long pants, and socks when outdoors. Treat clothing and gear with permethrin for added protection. Mosquitoes here bite throughout the day, not just at dawn and dusk.

Use air conditioning and ensure window and door screens are intact. Sleep under insecticide-treated bed nets if screens are unavailable, particularly important for pregnant women.

Seek immediate medical attention if you develop fever, rash, joint pain, or red eyes. Inform your healthcare provider of any travel history to affected areas.

Pregnant women should consult healthcare providers about travel plans to Recife and take extra precautions against mosquito bites.
