Which disease is commonly associated with mosquitoes as vectors?

• A. Measles
• B. Typhoid fever
• C. Malaria
• D. Hepatitis A

Answer: (C)

Malaria is commonly associated with mosquitoes as vectors because its transmission is primarily facilitated by female Anopheles mosquitoes. When these mosquitoes bite a human host, they can inject the Plasmodium parasite, which is responsible for malaria. This disease is characterized by symptoms such as fever, chills, and flu-like illness, and it is endemic in many tropical and subtropical regions where the Anopheles mosquito is prevalent.

In contrast, other diseases mentioned do not rely on mosquitoes for transmission. Measles is caused by a virus and is spread through respiratory droplets. Typhoid fever is a bacterial infection typically transmitted through contaminated food and water. Hepatitis A is also a viral infection that spreads mainly through the ingestion of contaminated food and water, not through mosquito bites. Understanding the vector-host relationship in diseases like malaria is crucial for implementing effective prevention and control strategies.
