Which demographic is most at risk for developing Typhoid Fever?

Individuals in developing countries with poor sanitation are the demographic most at risk for developing Typhoid Fever. This is primarily due to the conditions that promote the spread of the disease, such as inadequate access to clean water, poor sanitation and hygiene practices, and limited healthcare infrastructure. Typhoid Fever is caused by the bacteria Salmonella typhi, which is transmitted through contaminated food and water. In areas where sanitation is lacking, the likelihood of exposure to contaminated sources is significantly increased.

In contrast, while urban populations in developed countries may also face health challenges, they generally have better sanitation and public health measures in place, which reduce the risk of typhoid transmission. Children under the age of five can be more susceptible to certain diseases overall, but Typhoid Fever specifically is less about age and more about environmental conditions. Travelers with weak immune systems are at risk as well, but they typically encounter the disease when visiting locations where sanitation is poor. Thus, the vulnerability is primarily linked to the broader environmental conditions present in developing countries, making this demographic most at risk.
