Which of the following diseases is not spread through infected blood?

Appeared in: MP CHO -2021 (Shift 1st)

Explanation

Hepatitis E virus (HEV) is the correct answer as its primary mode of transmission is fecal-oral.
The virus spreads mainly through the ingestion of contaminated water or food.
Unlike Hepatitis B, C, and HIV, HEV is not primarily considered a bloodborne pathogen, although rare instances of transmission through blood have been noted.
Outbreaks are common in regions with poor sanitation and contaminated water supplies.

Option A: Hepatitis B (HBV) is a classic bloodborne pathogen.
Option B: Hepatitis C (HCV) is primarily transmitted through contact with infected blood.
Option C: Human Immunodeficiency Virus (HIV) is a well-known bloodborne virus.

Clinical Relevance

Nursing practice connection: Knowing Modes of transmission for infectious diseases, specifically viral hepatitis and HIV helps nurses interpret findings accurately and avoid errors in routine assessment, medication administration, and patient teaching.
Understanding transmission routes is fundamental to nursing practice for implementing appropriate infection control measures (e.g., standard precautions vs. contact/enteric precautions).
Nurses play a key role in patient education regarding prevention, such as advising travelers to endemic areas about food and water safety to prevent Hepatitis E.
For bloodborne pathogens like HBV, HCV, and HIV, nurses must be vigilant with sharps safety, post-exposure prophylaxis protocols, and counseling patients on safe practices.

How to Approach the Question

First, identify the core question: It asks to find the disease that is an exception ('not') to a specific mode of transmission (infected blood).
Review each option and recall its primary transmission route.
Option A (Hep-B): Recall it's bloodborne and sexually transmitted.
Option B (Hep-C): Recall it's primarily bloodborne (e.g., IV drug use).
Option C (HIV): Recall it's transmitted via blood and body fluids.
Option D (Hep-E): Recall it's transmitted via the fecal-oral route, often through contaminated water.

Concept Tested & Keywords

Concept Tested: Modes of transmission for infectious diseases, specifically viral hepatitis and HIV.
Stem keywords: diseases, spread, infected blood
Lead-in keywords: not
Negative lead-in flag: Question asks for the exception (NOT spread by blood).
