The Centers for Disease Control and Prevention (CDC) issued a travel notice for the South American country of Peru after several locally transmitted Zika infections were reported.
CDC recommends that travelers to Peru protect themselves from mosquito bites. The mosquitoes that spread Zika usually do not live at elevations above 6,500 feet (2,000 meters) because of environmental conditions. Travelers whose itineraries are limited to areas above this elevation are at minimal risk of getting Zika from a mosquito.
Many people infected with Zika virus do not get sick. Among those who do develop symptoms, sickness is usually mild, with symptoms that last for several days to a week. Guillain-Barré syndrome (GBS), a rare disorder that can cause muscle weakness and paralysis for a few weeks to several months, is very likely triggered by Zika in a small proportion of infections, much as it is after a variety of other infections. Most people fully recover from GBS, but some have permanent damage.
A pregnant woman can pass Zika virus to her fetus. Infection during pregnancy can cause serious birth defects. CDC recommends special precautions for the following groups:
- Women who are pregnant:
- Should not travel to any area of Peru below 6,500 feet (see map).
- If you must travel to one of these areas, talk to your doctor first and strictly follow steps to prevent mosquito bites during your trip. If your itinerary is limited entirely to areas above 6,500 feet, there is minimal risk of getting Zika from a mosquito.
- If you have a male partner who lives in or has traveled to Peru, either use condoms or do not have sex (vaginal, anal, or oral) during your pregnancy.
