Current Question (ID: 16114)

Question:

Which of the following statements is correct? A. Common cold - Droplet Infection. B. Typhoid - Contaminated food & water. C. AIDS - Shaking hands. D. Ringworm - Using infected towels.

Options:

1. A and B
2. C and D
3. A and C
4. A, B and D

Solution:

Common cold can take place from one person to other as it is communicable in nature. A healthy person can get infected by being in close vicinity of infected person when he/she sneezes, coughs, as the droplets generated by sneeze and cough contain infecting agents. Typhoid occurs by the intake of contaminated water & food. While ringworm is one of the skin disease which can transfer from one person to other by the use of infected towel & handkerchief. AIDS (Acquired Immuno deficiency) does not occur or transfer by shaking hands.
