INFECTION CONTROL AND PREVENTION IS THE GOOD WAY THAT MANAGING INFECTION IN HEALTH CARE

1. Infection Control & Prevention Presented by: DLER JABAR HEALTH AND SAFETY MINI MASTER

2. Introduction (Cont.) Infection control addresses factors related to the spread of infections within the healthcare setting:

3. Introduction (Cont.) Hand hygiene/handwashing Cleaning Disinfection Sterilization Vaccination Surveillance Monitoring/investigation of demonstrated or suspected spread of infection within a particular health-care setting (surveillance and outbreak investigation), And management (interruption of outbreaks). Infection control also includes prevention via:

4. Definition Pathogenic microorganisms proliferate and invade bodily tissue, causing tissue harm and disease. The invasion and multiplication of microorganisms such as bacteria, viruses, and parasites those are not normally present within the body. An infection may cause no symptoms and be subclinical, or it may cause symptoms and be clinically apparent.

5. Definition (Cont.) An infection may remain localized, or it may spread through the blood or lymphatic vessels to become systemic (body wide). Microorganisms that live naturally in the body are not considered infections. For example, bacteria that normally live within the mouth and intestine are not infections.

6. Infection prevention Infection prevention policies and practices are used in hospitals and other health care facilities to reduce the spread of infections. This Photo by Unknown Author is licensed under CC BY-NC-ND

7. Infectious diseases Infectious diseases kill the most people worldwide. Germs cause infections. Germs are microscopic organisms found in air, soil, and water. Germs can spread by touching, eating, drinking, or breathing. Kissing, sexual contact, and animal bites transfer germs. Vaccination, handwashing, and medicines can prevent illnesses.

12. Chain of infection For infectious disease to spread, several necessary steps must occur. These steps are known as “chain of infection”. An infection will develop only if chain remains intact. These links are:

13. A. Causative agent The microorganism (for example bacteria, virus, protozoa or fungi).

14. B. Reservoir A host which allows the microorganism to live, and possibly grow, and multiply. Humans, animals and the environment can all be reservoirs for microorganisms.

15. Portal of exit P ath for the microorganism to escape from the host. Examples: blood, respiratory tract, skin and mucous membranes, genitourinary tract, gastrointestinal tract, and transplacental pathway from mother to unborn infant.

16. Mode of infection Since microorganisms cannot travel on their own; they require a vehicle to carry them to other people and places. Infectious diseases and even certain contagious diseases spread through the following agencies:

17. Portal of entry a path for the microorganism to get into a new host.

18. Susceptible host A person susceptible to the microorganism
