• Infection control and prevention section.
Unit learning outcomes• A Understand the causes of infections
and transmission of infection• B Explore how to prevent and control the
transmission of infection in health and• social care settings• C Investigate the roles and
responsibilities of health and social care organisations and
• workers in preventing and controlling infections.
Grading Criteria• 7 passes • 3 merits • 3 distinctions• 2 practical's
An invasion of body tissue by
pathogens (microorganism
) and their growth there.
WHAT IS INFECTION?
• Bacteria, viruses, protozoans, fungi, and other parasites called pathogens are capable of causing a change that disrupts the homeostasis in the body.

Causes of infection
Definition of Pathogen• Noun• A bacterium, virus, or other
microorganism that can cause disease
• Not all microorganisms are pathogenic; your body is host to billions of microorganisms, most of which are bacteria. These microorganisms have a symbiotic relationship with your body helping to keep harmful bacteria and other microorganisms from growing.
Type of pathogens causing infection
Bacteria, Viruses , Fungi , Parasites Type of infections • Local: limited to specific part of the
body.• Systemic: pathogens spread and
damage systems of the body.• Bacteremia: when a culture of the
person’s blood reveals microorganisms. • Septicemia: when Bacteremia results in
systematic infections.
• If beneficial organisms are eliminated from your body, pathogens can establish themselves and cause infectious disease. In addition, if beneficial organisms enter areas of the body where they are not normally found, these formerly harmless organisms can become potential pathogens
Disease Cause Affected Organ Transmission
Smallpox Virus Skin Droplet
Influenza Virus Respiratory system Direct contact
HIV/AIDS Virus Immune system Body Fluid
Hepatitis B Virus Liver Body Fluid
Tetanus Bacteria Nervous system Puncture Wound
Strep Throat Bacteria Respiratory system Droplet
Tuberculosis Bacteria Respiratory Droplet

Type of infections • Acute infections: generally
appear suddenly or last a short time.
• A chronic infections : occur slowly, over a very long period and may last months or years.
• Sepsis: Is the state of infection.
• Asepsis : Is the freedom from disease microorganisms.
• Clean : absence of almost all microorganisms.
What is Infection Control:
• All of the practices used to prevent the spread of microorganisms that could cause disease in a person.
• Infection control practices help to protect clients and healthcare providers from disease by reducing and/or eliminating sources of infection.

Transmission of disease• Pathogens can be transmitted to a host
from a reservoir four main ways; 1.By direct contact; exchange of body fluid
especially during sexual intercourse2.By an object; people handle contaminate
objects then touch face, nose, eyes, etc…3.Through the air; person coughs or sneezes
spreading droplets which are then inhaled4.By a vector; insects such as mosquitos,
ticks spread pathogens between hosts or reservoirs
