Which of the following statements is correct?

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

Explanation

Dengue is a viral infection caused by the dengue virus (DENV), which is a flavivirus.
It is transmitted to humans through the bite of an infected female Aedes mosquito, primarily Aedes aegypti.
This mode of transmission correctly classifies it as a mosquito-borne (a type of vector-borne) disease.

Option B: Malaria is a classic example of a communicable disease. It is caused by a parasite (Plasmodium) and transmitted between people by a vector (Anopheles mosquito).
Option C: H1N1 is the specific subtype of the Influenza A virus that is responsible for the illness commonly known as 'swine flu'. The link is direct and causal.
Option D: Typhoid fever is caused by the bacterium Salmonella Typhi and is spread almost exclusively through the fecal-oral route, via ingestion of contaminated food or water.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Modes of transmission for common communicable diseases as background academic context rather than a clinical decision trigger.
Understanding transmission routes is critical for nurses to provide accurate patient education on prevention, such as using mosquito nets for malaria, eliminating stagnant water for dengue, practicing hand hygiene for typhoid, and respiratory etiquette for H1N1.
In a clinical setting, this knowledge dictates the type of isolation precautions required. For example, a patient with H1N1 would require droplet precautions.
Public health nurses use this epidemiological information to track outbreaks and implement community-wide control measures.

How to Approach the Question

This is a factual recall question that tests your knowledge of common communicable diseases.
First, carefully read the question stem to understand that you need to identify the one 'correct' statement.
Evaluate each option independently based on your knowledge of pathology and community health nursing.
For Option A, recall that Dengue is spread by mosquitoes.
For Option B, recall that Malaria is spread by mosquitoes, making it a communicable (vector-borne) disease.
For Option C, recall that H1N1 is the virus that causes swine flu.
