Chain of infection
The chain of infection represents the transmission of microorganisms and subsequent infection within a health care setting, with each link in the chain representing a factor related to the spread of microorganisms.
Transmission occurs when the agent in the reservoir exits the reservoir through a portal of exit, travels via a mode of transmission and gains entry through a portal of entry to a susceptible host.
The strategies that will decrease exposure risk and prevent the transmission of microorganisms.are based on:
- client/patient/resident infection status (including colonization)
2.characteristics of the client/patient/resident
3.type of care activities to be performed
4.resources available for control
5.HCP’s immune status
Risks are assessed for
- Contamination of skin or clothing by microorganisms in the client/patient/resident environment
- Exposure to blood, body fluids, secretions, excretions, tissues exposure to non intact skin
- exposure to mucous membranes
- Wear gloves (clean, non-sterile) when touching blood, body fluids, secretions, excretions or mucous membranes.
- Change gloves between contacts with different patients.
- Remove gloves immediately after use and before attending to another patient.
- Wash hands immediately after removing gloves.
- Use a plain soap, antimicrobial agent or waterless antiseptic agent.
- Disposable gloves should not be reused but should be disposed of according to the health care facility protocol.
