Study Notes

Chain Of Infection

It is important to understand the chain of infection to prevent the spread of infectious diseases.
The components of the chain of infection are:
- Infectious agent: the pathogen that causes the disease
- Reservoir: the place where the pathogen lives and multiplies
- Portal of exit: the way the pathogen leaves the reservoir
- Mode of transmission: the way the pathogen travels from the reservoir to the host
- Portal of entry: the way the pathogen enters the new host
- Susceptible host: a person who is at risk of getting the disease

Laboratory Biosafety and Biosecurity

The importance of biosafety and biosecurity in the field of health sciences is to protect workers and the public from exposure to hazardous biological agents.
Biosafety practices are designed to prevent the accidental release of hazardous biological agents, while biosecurity practices are aimed at preventing the deliberate release of biological agents

Importance of Chain of Infection

Understanding the chain of infection is crucial for preventing the spread of diseases in healthcare settings and laboratories.
Knowledge of each component helps identify points of intervention to break the chain and control infections.

Components of the Chain of Infection

Infectious Agent: Microorganisms like bacteria, viruses, fungi, and parasites capable of causing disease.
Reservoir: The natural habitat for the infectious agent, such as humans, animals, or the environment.
Portal of Exit: How the infectious agent leaves the reservoir, often through bodily fluids like blood, urine, or respiratory droplets.
Mode of Transmission: The mechanism for spreading the agent from the reservoir to a susceptible host, including direct contact, droplet spread, airborne transmission, or contaminated objects.
Portal of Entry: The way the infectious agent enters the new host, similar to the portal of exit.
Susceptible Host: An individual who is at risk of becoming infected due to factors like age, health condition, and immune status.
