Original Khojo Papers practice question — not from a past board paper.
Answer
A vector is an organism that carries a pathogen from an infected person to a healthy one without itself suffering from the disease. The female Anopheles mosquito carries malaria, the female Aedes mosquito carries dengue, and the housefly carries typhoid and cholera.
No citable source has been recorded for this record. Treat it as practice material, not as fact.
Explanation
Controlling the vector is often the most effective way of controlling the disease.
