Zika Virus risk in Arequipa

Zika Virus Prevention Guide for Arequipa, Peru

Risk Score: 54/100 (Moderate)

What is Zika Virus

Zika is a disease spread primarily through the bite of infected Aedes mosquitoes, the same species that carries dengue and chikungunya. Most people experience mild symptoms like fever, rash, joint pain, and red eyes. However, Zika poses serious risks for pregnant women, as it can cause severe birth defects including microcephaly.

Why Arequipa Carries Moderate Risk

Arequipa sits at roughly 2,300 meters above sea level, which historically limited Aedes aegypti mosquito populations compared to coastal and jungle regions of Peru. However, urban expansion, rising temperatures, and increased travel from lowland areas have gradually raised concern. The risk score of 54 reflects this emerging but not yet critical threat. Local factors include warmer microclimates in certain districts, standing water in informal settlements, seasonal humidity spikes, and travelers arriving from higher-risk zones like Piura and Iquitos.

5 Actionable Prevention Steps

1. Eliminate standing water weekly. Check flower pots, discarded tires, buckets, and water storage containers around your home. Aedes mosquitoes breed in clean, stagnant water, not dirty water.

2. Use EPA-registered repellent daily, especially during early morning and late afternoon when Aedes mosquitoes are most active. Apply DEET, picaridin, or oil of lemon eucalyptus on exposed skin.

3. Wear long sleeves and pants during peak mosquito hours, particularly if visiting lower-altitude areas near Arequipa or traveling outside the city.

4. Use window screens and bed nets if sleeping with open windows. Arequipa's altitude offers some natural protection but do not rely on it alone.

5. If pregnant or planning pregnancy, consult your healthcare provider before any travel within Peru. Monitor local health advisories from the Peruvian Ministry of Health for updated risk zones.
