Hantavirus risk in Cali

Hantavirus Prevention Guide for Cali, Colombia

What is Hantavirus?

Hantavirus is a serious respiratory illness spread through contact with infected rodents, their droppings, urine, or saliva. In severe cases, it can lead to Hantavirus Pulmonary Syndrome, which requires urgent medical attention. The virus does not spread from person to person in South America.

Local Risk Factors in Cali

Cali's warm, humid climate and surrounding agricultural areas create favorable conditions for rodent populations. Risk increases near warehouses, storage facilities, farms, and rural outskirts where the Cali-Buga corridor and nearby farming communities see higher rodent activity. Seasonal rains can drive rodents into buildings seeking shelter. The risk score of 55/100 reflects moderate concern tied to periurban zones, grain storage areas, and informal housing near vegetation where rodent-human contact is more likely.

Actionable Prevention Steps

1. Seal your home and workplace. Close gaps larger than a quarter inch around doors, pipes, walls, and roofs using steel wool, metal flashing, or concrete. Rodents can squeeze through very small openings, so inspect storage rooms, sheds, and basements regularly.

2. Eliminate food sources. Store grains, pet food, and garbage in thick plastic or metal containers with tight lids. Clean up fallen fruit, bird feed, and food scraps promptly. Rodents thrive where food is accessible.

3. Handle cleaning safely. Never sweep or vacuum rodent-contaminated areas, as this stirs up infectious dust. Instead, wet droppings and nesting material with a bleach solution, wait five minutes, then bag and dispose of waste while wearing gloves and a mask.

4. Reduce outdoor rodent habitat. Clear brush, woodpiles, and debris at least 30 meters from buildings. Keep grass trimmed and store firewood off the ground and away from walls.

5. Seek early medical care. If you develop fever, muscle aches, or breathing difficulty after possible rodent exposure, visit a clinic immediately. Mention your exposure history so doctors can consider Hantavirus early.
