Question

If interferons are being produced in the body of the sick person, the person is most likely to be suffering from:-
A. Typhoid
B. Malaria
C. Measles
D. Tetanus

Answer 1

Hint: Interferons are proteins produced by the cells which are infected from any virus and these interferons aware of the other cells from the infection.

Complete answer: 1. Interferons are a group of protein molecules which is used to communicate with the nearby cells, it is produced by the host cell in the response to some viral infection
2. Interferons are the large type of protein that belongs to the class of large molecules and the Cytokines which are helpful in cell Communication.
3. By the release of interferons, communication between the cells takes place and activates the defense mechanism and the immune system of the body which deactivates the pathogen from the body.
4. Interferons are in the response of the virus infection, it works like when the host cell got the viral infection then it produces a highly coiled protein which is called interferons, which provides a signal to the other cells and protects them from further viral infection.
5. here typhoid is caused by bacteria also malaria and tetanus are caused by bacterial infection only measles is caused by a viral infection.
6. Measles virus is a member of the morbillivirus group of viruses.
7. After infection the host cell releases these Cytokines and protects the cells from several infections.
So the person is suffering from the disease Measles.

 So option C is correct.

Note: Causative organism of typhoid Salmonella typhi,
Malaria - Plasmodium malarae,
Tetanus - Clostridium tetani,
