Typhoid Fever risk in Lusaka

Typhoid Fever is a bacterial infection caused by Salmonella typhi, spread through contaminated food and water. Symptoms include prolonged fever, headache, stomach pain, and weakness. Without treatment, it can become serious.

Lusaka's risk score of 60/100 reflects several local factors: the city's rapid urbanisation has strained water infrastructure, leading to contamination of piped water, especially in townships like Kalingalinga, Chawama, and Mtendere where boreholes and shallow wells are common and prone to sewage contamination. Street food vendors along Cairo Road and Soweto market often operate without proper handwashing facilities, and the hot rainy season from November to April increases flooding that spreads contaminants into water sources.

Here are five practical prevention steps for Lusaka residents:

1. Boil all drinking water for at least one minute before use, especially during and after the rainy season, and store in clean covered containers. This is the single most effective measure in areas with unreliable piped water.

2. Wash hands thoroughly with soap and clean water before eating and after using the toilet. Carry hand sanitiser when soap and water are unavailable, particularly when eating from vendors.

3. Eat food that is thoroughly cooked and served hot. Avoid raw vegetables and unpeeled fruits from street vendors, and be cautious with salads and fruit sold at markets.

4. Consider typhoid vaccination, especially if you live in high-risk areas or travel frequently within the city. Consult your nearest clinic about availability.

5. Report burst sewage pipes and contaminated water sources to Lusaka City Council or your area representative to help reduce community spread.

If you experience persistent fever lasting more than three days, visit your nearest health facility immediately for testing and treatment. Early detection prevents complications and further transmission.
