Where would typhoid cases normally concentrated?

Typhoid cases are normally concentrated in areas with poor sanitation and hygiene. These areas often lack access to clean water, adequate sewage systems, and proper waste disposal methods. This creates an environment where the bacteria that cause typhoid fever, Salmonella Typhi, can easily spread through contaminated food, water, or contact with an infected person. Typhoid fever is also more common in developing countries, where these conditions are more prevalent.
