Strategies for Reducing Infectious Diseases

Q. The spread of mosquito-borne diseases can be controlled by introducing vector control fish such as:

1. Gambusia
2. Labeo
3. Hilsa
4. Catla

Q.

Which is an effective method to control mosquito breeding?

1. Use of mosquito repellents

2. Cultivation of Gambusia fishes that eat the larvae of mosquitoes

Q.

Match the disease in Column I with the appropriate items (pathogen/prevention/treatment) in Column II.
Column I Column II
(A) Amoebiasis (i) Treponema pallidum
(B) Diphtheria (ii) Use only sterilized food and water
(C) Cholera (iii) DPT vaccine
(D) Syphilis (iv) Use oral rehydration therapy

1. A = (ii), B = (i), C = (iii), D = (iv)

2. A = (ii), B = (iii), C = (iv), D = (i)

3. A = (i), B = (ii), C = (iii), D = (iv)

4. A = (ii), B = (iv), C = (i), D = (iii)

Q. is a preparation of antigenic proteins of pathogens or inactivated pathogens introduced into the body to produce antibodies against a disease.

1. Serum
2. Colostrum
3. Blood
4. Vaccine
