Question

What are the 6 steps of the chain of infection (transfer of infection)?

1) Incubation, Prodromal, Acute, Decline, Convalescent, Recovery
2) Entry, Transmission, Colonization, Infection, Disease, Outcome
3) Reservoir, Portal of Exit, Mode of Transmission, Portal of Entry, Susceptible Host
4) Hand hygiene, Respiratory hygiene, Environmental cleaning, Safe injection practices, Safe food handling, Personal protective equipment

Answer 1

The 6 steps of the chain of infection are reservoir, portal of exit, mode of transmission, portal of entry, susceptible host, and infectious disease. Understanding these steps is important for preventing the spread of infectious diseases.

Step-by-step explanation:

The 6 steps of the chain of infection are:

1. Reservoir: the source of the infectious agent (e.g., humans, animals, environment)
2. Portal of Exit: the route by which the infectious agent leaves the reservoir (e.g., respiratory droplets, fecal-oral)
3. Mode of Transmission: how the infectious agent is transmitted from the reservoir to the susceptible host (e.g., direct contact, airborne)
4. Portal of Entry: the route by which the infectious agent enters the susceptible host (e.g., skin, mucous membranes)
5. Susceptible Host: an individual who is capable of being infected by the infectious agent
6. Infectious Disease: the development of signs and symptoms of infection in the susceptible host

These steps are important to understand in order to prevent the spread of infectious diseases and implement appropriate control measures.
