The chain of infection is commonly described as having six links. These links represent the steps involved in the transmission of infectious diseases:
1. **Infectious Agent** - The pathogen that causes the disease (bacteria, virus, fungus, parasite).
2. **Reservoir** - The natural habitat of the infectious agent (humans, animals, environment).
3. **Portal of Exit** - The route by which the infectious agent leaves the reservoir (e.g., respiratory tract, blood).
4. **Mode of Transmission** - The way the infectious agent is spread (direct contact, airborne, vector-borne).
5. **Portal of Entry** - The way the infectious agent enters a new host (e.g., mucous membranes, breaks in the skin).
6. **Susceptible Host** - An individual who is at risk of infection due to various factors (age, health status, etc.).
So the correct response is **Six**.
