Infection Control for Health Science
Understanding the basics of preventing disease transmission Essential knowledge for health science students Grade 9 Health Education
What is Infection Control?
The practice of preventing the spread of infections Protects patients, healthcare workers, and visitors Combines scientific knowledge with practical procedures Essential in all healthcare settings
The Chain of Infection
Infectious agent (pathogen) Reservoir (where pathogen lives) Portal of exit (how pathogen leaves) Mode of transmission (how it spreads) Portal of entry (how it enters new host) Susceptible host (person who can get infected)
Types of Pathogens
{"left":"Bacteria - single-celled organisms that can multiply rapidly\nViruses - tiny infectious agents that need host cells to reproduce","right":"Fungi - organisms like yeasts and molds that can cause infections\nParasites - organisms that live on or in another organism"}
Standard Precautions
Hand hygiene - most important infection control measure Personal protective equipment (PPE) Safe injection practices Proper handling of contaminated equipment Environmental cleaning and disinfection
Hand Hygiene Challenge
Practice the 6-step hand washing technique Time yourselves - should take 20-30 seconds Use the WHO hand hygiene method Check if you missed any spots with UV gel demonstration
Personal Protective Equipment (PPE)
Gloves - protect hands from contamination Masks - prevent respiratory droplet transmission Eye protection - shields from splashes Gowns - protect clothing and skin Must be put on and removed in correct order
Scenario Discussion
A patient comes to the clinic with a persistent cough What infection control measures should be taken? Consider: hand hygiene, PPE, patient placement, environmental controls
Routes of Transmission
Infection Control in Daily Life
Cover coughs and sneezes with elbow Stay home when sick Keep vaccinations up to date Practice good personal hygiene Clean and disinfect frequently touched surfaces Prepare food safely
