Pathogens
This type of pathogen is free living, single-celled, and infections may be treated with antibiotics
Bacteria
Name 1 method of infection prevention
handwashing, vaccination, disinfecting/sterilization
Define an "infection"
The invasion and multiplication of
microorganisms such as bacteria, viruses, fungi,
and parasites that are not normally present
within the body.
a host may acquire this fungal pathogen from walking barefoot at a public pool or in a locker room
athlete's foot
This link in the chain is responsible for the proliferation of all pathogenic infections
susceptible host
This type of pathogen infects the host by incorporating its DNA into the host's cells
virus
Name a method of infection surveillance
monitoring populations for signs/symptoms, regular testing of the population, investigating suspected incidences, keeping record of positive cases in the community.
What do we call an infected person who shows zero symptoms?
asymptomatic
true or false; toenail fungus may be treated topically directly on the infected nail
False! The infected person must take antifungal pills or have their nail removed completely, then medicine applied to the exposed matrix.
This link is the "holding tank" where pathogens wait to be acquired by the host
reservoir
This type of pathogen is free-living and may infect the host via an animal reservoir
protists or protozoa
Name a method of infection management
quarantining suspected patients or isolation
What do we call an infection that stays within the affected area, such as a cut or sinus infection
Localized
True or false; Athlete's foot fungus only grows on the feet
False! The same species can grow anywhere on the body...especially in skin folds like the groin or underarms (jock itch)
This link allows the pathogen to escape the host and infect another
portal of exit
This pathogen cannot replicate independently
virus
According to the CDC, how many preventable infections occur every year?
2,000,000
What do we call the dangerous situation when an infection enters a host's bloodstream and becomes systemic
septicemia or "going septic"
yeast (candida)
this link is responsible for the host's symptoms...like sneezing or diarrhea
mode of transmission
These pathogens cannot be treated with antibiotics but rather with antiparisitics
protozoans or protists
How many people die each year from preventable infections, as per the CDC?
90,000
What do we call it when symptoms onset suddenly and are very severe
acute infection
You have gone camping for the weekend and used the public shower. A few days later, your toes become red, itchy, and scaly. You have acquired an athlete's foot infection!
Name 2 ways you could have prevented this from happening.
wear shower shoes, avoid using the public shower, bring your own disinfectant to use before entering the shower
Name a type of pathogen reservoir
soil, water, foods, animals, humans
