Question | Answer |
---|---|
What are the link in the Chain of Infection | 1.Causative agent (pathogen) 2.Reservoir host 3.Portal of exit 4.Mode of transmission 5.Portal of entry 6.Susceptible host |
A pathogen is known as a | Causative agent |
A reservoir host is an | Animal, insect, or human capable of sustaining growth of a pathogen |
A portal of exit is | How a pathogen leaves the body |
Exit portals include: | 1.Respirator: breathing, coughing, sneezing 2.GI - Gastrointestinal: emesis, or feces 3.GU - Genitourinary: urine, vaginal secretions, semen 4.Open wound: caused by a break in the skin |
The mode of transmission is how a pathogen is: | Transferred from a reservoir host to anouther susceptible host |
A living organism that carries pathogens from one infected person to another is called a: | Vector |
Modes of transmission include: | 1.Air; breathing 2.Droplet; coughing or sneezing 3.Contact; touch |
The most common mode of transmission is: | The hands |
The portal of entry is how: | A pathogen enters the body |
Entry portals include: | 1.Open wound / break in the skin 2.Mucous membranes; eyelids, nose, mouth, urethra, vagina, anus 3.Respiratory 4.GI; ingesting contaminated food/water 5.GU activites; coitus, copulation |
A susceptible host is one who does not have | Immunity to a pathogen that enters their body |
The susceptibility of a host will depend on: | The strength of the individuals immune system |
Immune system strength is directly related to: | 1.Nutrition 2.Exercise frequency 3.Tobacco/alcohol use 4.Sleep habits |
