Zika Virus risk in San Juan

Zika Virus Prevention Guide for San Juan Zika is a mosquito-borne illness spread primarily through the bite of an infected Aedes aegypti mosquito, the same species that carries dengue and chikungunya. Most people who get Zika experience mild symptoms like fever, rash, joint pain, and red eyes, though many show no symptoms at all. The serious concern is for pregnant women, as Zika can cause severe birth defects including microcephaly. Sexual transmission is also possible. San Juan's risk score of 62 reflects several local factors. The tropical climate keeps mosquitoes active year-round, with peak activity from June through November during rainy season. Old San Juan's dense urban layout, abundant standing water in containers and drains, and high population density create ideal breeding conditions. The Aedes aegypti mosquito likes to bite during daytime hours, especially in the early morning and late afternoon, and breeds in very small amounts of standing water found around homes and businesses. Here are five steps you can take right now to protect yourself and your family. First, eliminate standing water around your home weekly. Check flower pots, buckets, tires, birdbath water, and clogged gutters. The Aedes mosquito breeds in as little as a bottle cap of water. Second, use EPA-registered insect repellent containing DEET, picaridin, or oil of lemon eucalyptus on exposed skin. Reapply as directed, especially before outdoor activities. Third, wear long sleeves and pants during peak mosquito hours from dawn until dusk. Light-colored clothing works best since mosquitoes are attracted to dark colors. Fourth, use air conditioning and intact window screens when possible. Sleep under mosquito nets if windows lack screens. Fifth, if pregnant or planning pregnancy, consult your healthcare provider before traveling to or staying in San Juan. Use condoms or abstain from sex if your partner has been exposed, since Zika can persist in semen for months. Stay informed through the Puerto Rico Department of Health for local outbreak updates.
