Zika Virus risk in Manaus

Zika Prevention Guide for Manaus, Brazil Risk Score: 68/100 What is Zika? Zika is a virus spread mainly through the bite of infected Aedes aegypti mosquitoes, the same species that transmits dengue and chikungunya. Most people experience mild symptoms like fever, rash, joint pain, and red eyes. The real danger is for pregnant women, as Zika can cause serious birth defects including microcephaly. There is no vaccine or specific treatment. Local Risk Factors in Manaus Manaus sits in the Amazon basin where warm temperatures and heavy rainfall create ideal breeding conditions for mosquitoes year-round. Standing water collects in open containers, tires, construction sites, and poorly maintained water storage tanks throughout the city. Rapid urbanization and limited sanitation infrastructure in some neighborhoods increase exposure risk. The dense tropical environment means mosquitoes are active both day and dusk. Prevention Steps Eliminate standing water weekly. Check flower pots, buckets, gutters, old tires, and water tanks around your home. Cover all water storage containers tightly. Mosquitoes breed in even small amounts of stagnant water. Use registered insect repellent containing DEET, picaridin, or IR3535. Reapply as directed, especially during early morning and late afternoon when Aedes mosquitoes are most active. Sleep under mosquito nets and ensure window and door screens are intact and free of holes. Use air conditioning when available, as mosquitoes avoid cool environments. Wear long sleeves and long pants during peak biting hours. Light-colored clothing is preferable as mosquitoes are attracted to dark colors. Pregnant women should take extra precautions. Avoid unnecessary travel to high-risk areas within Manaus, use repellent daily, and consult your healthcare provider before and after any travel. Use condoms during pregnancy to prevent sexual transmission of the virus. Report mosquito breeding sites to local health authorities through the municipal dengue and Zika control programs.
