Which of the following diseases is commonly transmitted through the fecal/oral route?

Typhoid fever is a disease commonly transmitted through the fecal/oral route, which is characterized by the ingestion of food or water contaminated with the feces of an infected person. The causative agent of typhoid fever is the bacterium Salmonella enterica serotype Typhi, and it primarily spreads in areas with poor sanitation and hygiene practices. When an individual consumes contaminated food or water, the bacteria can enter the gastrointestinal tract, leading to infection.

In contrast, malaria is transmitted through the bite of infected mosquitoes, which is not related to the fecal/oral route. Tuberculosis (TB) is primarily spread through airborne droplets, as it is an infectious disease affecting the lungs, while influenza is similarly transmitted via respiratory droplets from coughs or sneezes of an infected person. This highlights the unique nature of typhoid fever in terms of transmission routes compared to the other diseases listed.
