INFECTION CONTROL
OBJECTIVES:
1. list conditions necessary for microorganisms to grow;
2. discuss the chain of infection; and
3. explain your role in interrupting bacteria transmission.
What I KNOW?
Activity 1.
Directions: Unscramble the letter by placing the correct letter sequence in the box
to
come up with the correct answer.

What’s IN?
The foundation of good infection control is to assume that everyone is
potentially infectious.
Infection is caused by pathogens such as bacteria, viruses, protozoa or fungi
getting
into your body. Pathogens are disease-producing microorganism. They destroy
human
tissue by using it as food and gives off waste products called toxin. Toxins are
poisonous to human body.
What’s NEW?
What are the different conditions for microorganism to grow?
Activity 2.
Directions: Write TRUE if the statement is correct and FALSE it is incorrect.
1. Bacteria grow well in the remains of food left in the patient’s room.
2. Darkness favors the development of bacteria
3. Bacteria do not grow in moist places
4. Almost all pathogens are aerobic
5. Low temperature do not kill bacteria but retard their activity and growth rate.
Six favorable conditions required for the growth of microorganism.
Food - F
Acidity - A
Time - T
Temperature – T
Oxygen - O
Moisture - M
Chain of infection
1. Causative agent - the pathogen that causes the diseases
2. Reservoir of the agent - the place where the pathogens lives and
reproduce
3. Portal of exit – the means by which the pathogens leaves the host
4. Portal of entry – means by which the pathogens enters the new host
5. Route of transmission – the way in which the pathogens travels from the
portal of exit of one host to the portal of entry of another
6. The susceptible host – a body that cannot resist the new pathogens and
its disease- producing toxins.
Activity 3.
Directions: Group the following according to their classification in the chain of
infection.
Bacteria Mouth Sneezing Parasite
Viruses Eyes Coughing
Food Blood Contact with infected person
Soil Saliva Eyes
Water Vomit Cut in the skins

People with weakened immune system

Signs and Symptoms of Infection
Fever
Chills and sweats
Cough
Sore throat
Shortness of breath
Nasal Congestions
Stiff neck
Diarrhea
Vomiting
Pain
Mode of Transmission
Direct Contact
Body surface-body surface transfer of pathogen
Indirect Transmission
Contact with contaminated objects
Droplet Transmission
Pathogens transfer via droplets through the air by talking, coughing and
sneezing.
Airborne Transmission
Pathogens transfer via evaporated droplets or dust particles moving
through
the air.
Nosocomial Transmission
An infection acquired while in a health care facility.
Aseptic Technique
Asepsis is the process of creating an environment free of disease-causing
organism. As caregiver or home health aid, you will share responsibility for
preventing the spread of diseases or infection by using aseptic technique.
1. Wash your hand after using the bathroom or blowing your nose, before
handling food, after caring for your client, before any procedures and before
meals.
2. Practice personal hygiene.
3. Cover your nose and mouth when you cough or sneeze. Wash your hands
after you cough.
4. Wash, dry and pull away all client- related equipment after used.
5. Disposed contaminated articles in proper way.
6. Cover cuts or open area in your skin
7. Wash your hands before you put on gloves and after you take it off.
PROPER HAND WASHING
HAND RUBBING
