Summary of “Infection Control Video”

Main Ideas and Concepts

1. Introduction to Infectious Agents

Infectious agents are biological organisms that cause infections and diseases. They include bacteria, viruses, fungi, and parasites. Understanding these agents is essential for effective infection control.

2. Types of Infectious Agents

• Bacteria Unicellular organisms that can live independently on surfaces. Many bacteria are beneficial, but some are pathogenic (e.g., E. coli, salmonella, tuberculosis). They are typically treated with antibiotics.

• Viruses Intracellular parasites that require a host to survive. Viruses are difficult to treat because destroying them often harms host cells. Treatment focuses on symptom management, with vaccines serving as the primary defense (e.g., common cold, HIV, Ebola).

• Fungi Can live independently and usually cause slow-developing, mild infections. However, infections can be severe in immunocompromised individuals (e.g., ringworm, thrush).

• Parasites Depend on hosts for survival and are often transmitted via contaminated food or water. They can cause mild to severe infections (e.g., roundworms, tapeworms).

3. Disease Transmission

Disease can be transmitted through various modes:

• Direct contact: Physical contact, sexual contact, injections, fecal contamination.
• Indirect contact: Touching contaminated surfaces.
• Droplet transmission: Exposure to droplets from coughing or sneezing.

Transmission requires a conducive environment and an intact chain of infection.

4. Chain of Infection

For disease to spread, six links must be intact:

1. Pathogenic agent: Bacteria, virus, fungi, or parasite.
2. Reservoir: Where the agent lives and multiplies (humans, animals, soil, contaminated food/water).
3. Portal of exit: How the agent leaves the reservoir (respiratory tract, wounds, bodily fluids).
4. Mode of transmission: Direct, indirect, or droplet.
5. Portal of entry: How the agent enters a new host (respiratory tract, mucous membranes, wounds).
6. Host susceptibility: Influenced by age, immune status, nutrition, and health conditions.

5. Infection Control Practices

The goal is to break the chain of infection and prevent disease spread. Key practices include:

• Effective hand-washing

  • Before and after every patient contact.
  • Use soap, running water, and disposable towels.

• Personal hygiene

  • Wear clean uniforms.
  • Keep nails short and clean; avoid artificial nails and excessive jewelry.

• Cleaning and disinfection

  • Clean all equipment and ambulance interiors after each use.
  • Use approved detergents and disinfectants.

• Use of Personal Protective Equipment (PPE)

  • Gloves (single-use, removed inside out).
  • Masks and safety glasses/goggles to protect eyes and mouth.
  • PPE protects both healthcare workers and patients.

• Immunizations

  • Protect against diseases such as hepatitis A/B, tetanus, flu, diphtheria, and whooping cough.

• Managing Exposure

  • Wash exposed skin with soap and water.
  • Rinse eyes with water or saline if exposed.
  • Rinse mouth thoroughly if exposed.

• Needlestick injury protocol

  • Wash injury site with soap and water.
  • Report and document the incident.
  • Dispose of sharps safely in designated containers.

• Waste disposal

  • Sharps in sharps containers only.
  • Contaminated waste in designated bags.
  • Clean the scene thoroughly after patient contact.

6. Isolation and Reporting

• Report exposure to infectious diseases immediately.
• May require isolation or removal from duty.
• Equipment and vehicles must be cleaned and disinfected.
• Follow workplace health and safety policies.

7. Conclusion

Infectious agents cause disease, and transmission depends on an intact chain of infection. Healthcare practitioners must rigorously apply infection control procedures to prevent disease spread.

PPE Usage

• Always wear gloves when in contact with patients or contaminated equipment.
• Remove gloves by turning them inside out to contain contaminants.
• Dispose of gloves properly.
• Wear masks and goggles when exposure to bodily fluids is possible.
• Wash hands after glove removal.

Exposure Management
