Cholera risk in Lima

Cholera Prevention Guide for Lima, Peru

Risk Score: 56/100

Cholera is a bacterial infection caused by Vibrio cholerae, spread primarily through contaminated water and food. It causes severe diarrhea and dehydration and can be life-threatening without prompt treatment.

Lima faces elevated cholera risk due to several local factors: aging water infrastructure in some districts, informal settlements with limited sanitation, street food vendors using untreated water, seasonal flooding that contaminates water sources, and high population density in areas like Villa El Salvador, San Juan de Lurigancho, and parts of Callao.

Your 5 Actionable Prevention Steps:

1. Drink only bottled or boiled water. If boiling, maintain a rolling boil for at least one minute. Avoid ice in drinks from street vendors unless you know it was made from purified water.

2. Eat thoroughly cooked food. Avoid raw seafood, especially ceviche from unverified vendors. Stick to hot, freshly cooked meals and peel fruits yourself.

3. Wash hands frequently with soap and clean water, especially before eating and after using the restroom. Carry hand sanitizer as backup.

4. Avoid swimming or wading in rivers, canals, or coastal waters near sewage outflow points, particularly in Callao and areas near the Chillón and Rímac rivers.

5. Know the signs and act fast. If you develop sudden watery diarrhea, seek medical care immediately. Oral rehydration salts are critical, and early treatment significantly reduces severity.

If traveling to or living in Lima, consider consulting a travel medicine specialist about the cholera vaccine before arrival. Keep oral rehydration packets accessible, and register with your local embassy for health alerts during outbreak seasons, typically warmer months from December through April.
