The Most Common Route of Transmission of Salmonella Enterica Typhi

Question

The most common route of transmission of Salmonella enterica typhi worldwide is through
A) contaminated food.
B) contaminated water.
C) direct contact.
D) insect vectors.

Accepted Answer

Salmonella enterica typhi is commonly transmitted through contaminated water. This happens when the bacteria-contaminated fecal matter enters the water systems, and then consumed by humans. While contaminated food can also transmit the bacteria, it is a less common route compared to contaminated water. Direct contact and transmission by insect vectors are also possible, but these are much rarer compared to contamination through water or food.
