What is the reservoir for Typhoid Fever?

The correct answer identifies the reservoir for Typhoid Fever as the feces and urine of a typhoid carrier. Typhoid Fever is caused by the bacterium Salmonella enterica serotype Typhi, which primarily exists in the intestines of infected humans. Carriers can excrete the bacteria in their feces and urine, even without showing symptoms of the disease themselves. This means that individuals who do not actively exhibit signs of Typhoid can still spread the bacteria, creating a significant public health concern.

While contaminated water and shellfish can also be involved in the transmission of the disease, the primary reservoir remains the carrier’s bodily excretions. The other options, such as garden soil, untreated dairy, and raw fruits and vegetables, do not serve as primary reservoirs for Typhoid Fever transmission, although improper handling or contamination of these food sources can lead to the disease spreading indirectly. Identifying the correct reservoir helps in implementing control measures to prevent outbreaks effectively.
