Question

What is the second link in the chain of transmission?

a) infectious agent
b) portal of entry
c) portal of exit
d) eservoirs

Answer 1

The chain of infection, if we think of it as an actualchain, is made up of six different links: pathogen (infectious agent), reservoir, portal of exit, means oftransmission, portal of entry, and the new host. Eachlink has a unique role in the chain, and each can be interrupted, or broken, through various means.

Answer 2

Correct answer choice is:

D. Reservoir.

Step-by-step explanation:

Further particularly, transmission transpires when the operator vacates its reservoir or host by a portal of an outlet, is carried by some convention of transmission and penetrates through a suitable portal of entry to contaminate a responsive host. This sequence is seldom called the chain of infection.

There are six links in the chain transmission, which includes:

1. The infectious agent

2. Reservoir

3. Portal of exit

4. Mode of transmission

5. Portal of entry

6. Susceptible host.
