All the following are vector borne diseases, except

Appeared in: KGMU 2024

Explanation

Hepatitis is a viral inflammation of the liver.
It is not transmitted by an arthropod vector like a mosquito or flea.
Hepatitis A and E are transmitted via the fecal-oral route (contaminated food/water).
Hepatitis B, C, and D are transmitted through parenteral routes, such as contact with infected blood or body fluids.

Option A: Malaria is a classic example of a vector-borne disease.
Option B: Filaria (Filariasis) is a parasitic disease transmitted by the bite of infected mosquitoes.
Option C: Plague is a bacterial disease transmitted to humans by the bite of infected fleas, which are vectors.

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 classification of vector-borne diseases as background academic context rather than a clinical decision trigger.
Understanding a disease's mode of transmission is fundamental for nursing practice, as it dictates the necessary infection control precautions and prevention strategies.
Nurses play a vital role in educating patients and communities about how to prevent diseases. For vector-borne diseases, this includes measures like using mosquito nets and repellents, while for hepatitis, it involves promoting safe drinking water, hygiene, and safe injection practices.
Public health initiatives for controlling vector-borne diseases (e.g., fogging, eliminating breeding sites) are distinct from those for hepatitis (e.g., vaccination programs, water purification).

How to Approach the Question

First, analyze the question and identify the keyword 'except'. This indicates you must find the option that does not belong to the specified category.
Define the category mentioned in the stem: 'vector-borne diseases'. Recall that these are illnesses transmitted by living organisms (vectors), typically arthropods like mosquitoes, ticks, and fleas.
Systematically evaluate each option against this definition.
Consider Malaria: Is it vector-borne? Yes, by mosquitoes.
Consider Filaria: Is it vector-borne? Yes, by mosquitoes.
Consider Plague: Is it vector-borne? Yes, by fleas.

Concept Tested & Keywords

Concept Tested: Modes of disease transmission and classification of vector-borne diseases.
Stem keywords: vector borne diseases
Lead-in keywords: except
Negative lead-in flag: The question asks for the option that is NOT a vector-borne disease.
