Question

The National Vector Borne Disease Control Programme does not cover which of the following disease
A. Dengue
B. Polio
C. Malaria
D. Filaria

Answer 1

A vector is an organism like arthropod or any other living organism, which can transfer infectious agents to a susceptible host and the diseases caused by vectors are called vector borne diseases.

Complete answer:
There are various infectious diseases that are caused in humans with the help of vectors like mosquito, house fly, fleas, louse etc. These vector borne diseases are malaria, dengue, filaria, kala-azar, Japanese encephalitis, Chikungunya, etc. National Vector borne Disease Control Programme is an agency made by the Ministry of Health and Family Welfare, Government of India for the control and prevention of the above six vector borne diseases.

Option A: Dengue is a disease caused by dengue virus. It spreads from infected person to an uninfected persons through infected Aedes aegypti mosquito.

Option B: Polio is also a viral disease caused by poliovirus in children. It spreads through droplets of sneezing, cough and by the contact of faces of infected people.

Option C: Malaria is a disease caused by protozoan parasites, like plasmodium. It is transmitted through the bite of an infected Anopheles mosquito.

Option D: Filaria is caused by roundworms or nematodes like Wuchereria bancrofti. It is transmitted from an infected person to a non-infected person through the bite of an infected mosquito.

Thus, the dengue, malaria and filaria are transmitted from an infected person to an uninfected person by vectors like mosquito and only polio is not transmitted through vectors. Hence, polio is not a Vector Borne Disease and it is not included in the National water Borne Disease Control Programme.

Hence, the correct answer is option (B).

Note: The vector borne diseases can be prevented by preventing the number of mosquitoes in our locality. We should keep the nearby places clean and do not allow water to get collected where Mosquito can reproduce, to prevent ourselves from vector borne diseases.
