All diseases spread through the respiratory route, except for which one of the following?

Appeared in: MP CHO -2019 (Shift-1)

Explanation

  • Typhoid fever is caused by the bacterium Salmonella typhi.
  • Its 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 of an infected person or a chronic carrier.
  • Unlike the other options, it does not spread through coughing, sneezing, or airborne particles.

Why Other Options Were Wrong

  • Option A: Influenza is a classic respiratory illness that spreads through droplets generated when an infected person coughs, sneezes, or talks.
  • Option B: Mumps is a viral disease that spreads through direct contact with saliva or respiratory droplets from the mouth, nose, or throat of an infected person.
  • Option C: Measles is a highly contagious viral disease that spreads through the air when an infected person coughs or sneezes. It is transmitted via both respiratory droplets and smaller airborne particles.

Clinical Relevance
  • Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Modes of disease transmission and infection control as background academic context rather than a clinical decision trigger.
  • A nurse must accurately identify a disease's transmission route to implement the correct type of isolation precautions (Standard, Contact, Droplet, or Airborne), which is fundamental to preventing nosocomial (hospital-acquired) infections.
  • For a patient with Typhoid, the nurse's priority is enforcing contact precautions and meticulous hand hygiene, especially after using the toilet, and ensuring the patient has access to a separate, clean bathroom if possible.
  • Patient education on handwashing, food safety, and clean water is a key nursing role in preventing the spread of fecal-oral diseases like Typhoid in the community.
How to Approach the Question
  • First, identify the keyword 'except' in the question stem. This indicates you are looking for the option that does not fit the stated category.
  • The category given is 'spread through the respiratory route'.
  • Review each option and recall its primary mode of transmission.
  • Evaluate Influenza: Spreads via respiratory droplets.
  • Evaluate Mumps: Spreads via respiratory droplets.
  • Evaluate Measles: Spreads via airborne respiratory particles.
Concept Tested & Keywords
  • Concept Tested: Modes of disease transmission and infection control.
  • Stem keywords: diseases, spread, respiratory route
  • Lead-in keywords: except
  • Negative lead-in flag: EXCEPT based question
