Transmission of typhoid is by?

Appeared in: NCL (MP) Nursing Officer - 2020

Explanation

Typhoid fever is caused by the bacterium Salmonella Typhi, which is found only in humans.
The primary mode of transmission is the fecal-oral route.
This occurs through the ingestion of food or water that has been contaminated with the feces or urine of an infected person or a chronic carrier.
Common vehicles for transmission include contaminated water, milk, ice, and street-vended foods.

Option A: Typhoid is not a bloodborne disease in terms of transmission between people. While bacteria are present in the blood during infection (bacteremia), this is not the route of spread.
Option C: The bacteria causing typhoid, S. Typhi, are not spread through the air via respiratory droplets from coughing or sneezing.
Option D: This option is incorrect because a valid mode of transmission is listed among the choices. 'Infected food and water' is the well-established primary route for typhoid.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Mode of transmission for Typhoid fever as background academic context rather than a clinical decision trigger.
Understanding the fecal-oral transmission of typhoid is fundamental for nurses to provide effective patient education on prevention, especially regarding hand hygiene and food/water safety.
In a clinical setting, this knowledge dictates the use of contact (enteric) precautions to prevent nosocomial spread from an infected patient.
A key public health role for nurses is identifying potential outbreaks and educating communities, particularly in areas with poor sanitation where typhoid is endemic.

How to Approach the Question

First, identify the core subject of the question, which is the 'transmission of typhoid'.
Access your knowledge base about common infectious diseases. Recall that typhoid is an enteric (intestinal) illness.
Associate enteric illnesses with the fecal-oral route of transmission. This is a key link for many gastrointestinal pathogens.
Evaluate the given options based on this association:
'Blood product' relates to bloodborne diseases.
'Infected food and water' directly aligns with the fecal-oral route.
