Pathogens are harmful and can cause infections. Non-pathogens are microbes that do not usually cause an infection. Non-pathogens are microbes that do not usually cause an infection. Slide 3 INFECTION INFECTION An infection is a disease state resulting from the invasion and growth of microbes in the body. An infection is a disease state resulting from the invasion and growth of microbes in the body. A local infection is in a body part. A local infection is in a body part. A systemic infection involves the whole body. A systemic infection involves the whole body. An infection can become life-threatening before the older person has obvious signs and symptoms. An infection can become life-threatening before the older person has obvious signs and symptoms. Slide 4 Spread of Infection How infection is spread: How infection is spread: Direct contact Direct contact Touching an infected person Touching an infected person Indirect contact Indirect contact Touching environmental surfaces and fomites such as linen, supplies, or equipment that have pathogens on them Touching environmental surfaces and fomites such as linen, supplies, or equipment that have pathogens on them Slide 5 The ability to resist infection relates to: The ability to resist infection relates to: Age Age Nutrition Nutrition Stress Stress Fatigue Fatigue Health Health Drugs Drugs Disease and injury Disease and injury Slide 6 Spread of Infection Airborne Airborne Mucus contains pathogens expelled into the air by coughing or sneezing Mucus contains pathogens expelled into the air by coughing or sneezing Pathogens travel long distances in ventilation systems, dust, or on moisture in the air Pathogens travel long distances in ventilation systems, dust, or on moisture in the air Invisible to the eye and easily inhaled Invisible to the eye and easily inhaled Slide 7 Spread of Infection Droplets Droplets Large and heavy Large and heavy Remain within three feet of the patient Remain within three feet of the patient Fall to the ground quickly Fall to the ground quickly Contain pathogens that are inhaled or picked up on the hands Contain pathogens that are inhaled or picked up on the hands Slide 8 Spread of Infection Common Vehicle Common Vehicle Contaminated food, water, feeding formulas, and equipment used for procedures Contaminated food, water, feeding formulas, and equipment used for procedures Pathogens are consumed when eating and drinking Pathogens are consumed when eating and drinking Slide 9 Spread of Infection Vectors Vectors Insects, rodents, and small animals can carry pathogens and transmit them to humans Insects, rodents, and small animals can carry pathogens and transmit them to humans Slide 10 Chain of Infection Factors necessary for infection to develop Factors necessary for infection to develop Breaking a link in the chain will prevent an infection from spreading Breaking a link in the chain will prevent an infection from spreading Slide 11 Chain of Infection Source Source Disease-causing pathogen Disease-causing pathogen Mode of transmission Mode of transmission How the pathogen is spread How the pathogen is spread Susceptible host Susceptible host Person who can become infected Person who can become infected Slide 12 Chain of Infection Carrier Carrier Infected person who can spread the disease Infected person who can spread the disease He or she may not know of the infection He or she may not know of the infection Portal of entry Portal of entry Place where the microbe enters the body Place where the microbe enters the body Slide 13 Chain of Infection Portal of exit Portal of exit Secretions, excretions, or droplets in which the pathogens travel when they leave the body Secretions, excretions, or droplets in which the pathogens travel when they leave the body Slide 14 Handwashing Most important way to prevent spread of microorganisms.
