Zika Virus risk in La Paz

Zika Virus Prevention Guide for La Paz, Bolivia Risk Score: 53/100 (Moderate Risk)

Zika virus is a mosquito-borne illness spread primarily through the bite of infected Aedes mosquitoes. Most people experience mild symptoms including fever, rash, joint pain, and conjunctivitis, though infection during pregnancy can cause serious birth defects. There is no specific treatment or vaccine available.

Local Risk Factors in La Paz La Paz sits at high altitude (3,600+ meters), which naturally limits mosquito breeding compared to lowland tropical areas of Bolivia. However, the subtropical Yungas region surrounding La Paz maintains year-round transmission risk. The rainy season (November through March) increases mosquito activity. Urban areas with standing water, poor drainage, and warmer microclimates create localized breeding zones. Travel to lower-altitude regions like Santa Cruz or the Amazon basin significantly raises your exposure.

Prevention Steps

1. Eliminate standing water around your living area. Empty, scrub, or cover any containers holding water weekly. Check flower pots, tires, buckets, and rooftop collections after rain. This single action removes breeding sites.

2. Use EPA-registered insect repellent containing DEET, picaridin, or oil of lemon eucalyptus on exposed skin. Reapply every few hours, especially during dawn and dusk when Aedes mosquitoes are most active.

3. Wear long sleeves and pants in light colors. Treat clothing with permethrin for added protection during outdoor activities in the Yungas or lowland regions.

4. Sleep under bed nets if staying in accommodations without screens or air conditioning, particularly in rural or low-altitude areas of the department.

5. If pregnant or planning pregnancy, avoid nonessential travel to lower-altitude zones. Consult your healthcare provider before any travel to tropical regions of Bolivia.
