Zika Virus risk in Lima

Zika Virus Prevention Guide for Lima, Peru Zika is a mosquito-borne illness caused by a virus transmitted primarily by Aedes aegypti mosquitoes, the same species that spreads dengue and chikungunya. Most infected people experience mild symptoms including fever, rash, joint pain, and conjunctivitis. However, Zika poses serious risks for pregnant women, as it can cause severe birth defects like microcephaly. There is no vaccine or specific treatment. Lima's risk score of 65/100 reflects several local factors. The city's coastal climate with warm temperatures and seasonal humidity creates favorable mosquito breeding conditions. Informal settlements and areas with inadequate water storage practices increase standing water accumulation. Poor drainage systems during the rainy season amplify mosquito populations. Additionally, international travel connections mean infected individuals can introduce the virus. Prevention Steps Eliminate standing water. Empty, scrub, and cover any containers that hold water, including buckets, tires, flower pots, and pet bowls. Mosquitoes breed in even small amounts of stagnant water. Do this weekly. Use EPA-registered insect repellent. Apply products containing DEET, picaridin, or oil of lemon eucalyptus on exposed skin, especially during early morning and late afternoon when Aedes mosquitoes are most active. Wear protective clothing. Choose long sleeves, long pants, and light-colored clothing. Treat garments with permethrin for added protection. Install and maintain window and door screens. Repair any tears or gaps. Use air conditioning when available, as cooler indoor temperatures reduce mosquito activity. Protect pregnant women with extra caution. Avoid travel to areas with active Zika transmission if pregnant or planning pregnancy. Use condoms during sexual activity, as Zika can be sexually transmitted for months after infection.
