Infection Prevention and Disease Control 2 Flashcards
what are the 5 modes of transmission?
contact (direct/indirect), droplet, airborne, common vehicle, vector
what is direct contact (transmission)?
touching someone (person to person) ex: kissing, sexual contact, body lesions
what are some examples of pathogens spreading with direct contact?
staphylococcus, MRSA, C-Diff, VRE, HPV
what is indirect contact (transmission)?
transfer of a pathogen via a fomite (person to object to person) ex: doorknobs, call bell, linen, gloves
what are some examples of pathogens that spread with indirect contact?
MRSA, VRE, C-DIff, staphylococcus, RSV
what is droplet transmission?
pathogen spread via droplets from a person (person-air-person) propelled a short distance in the air (2m) ex: sneezing, coughing, talking
what are examples of pathogens spreading via droplets?
influenza, ebola, SARS, COVID-19, rubella
how can droplets become smaller and spread farther?
if having an aerosol generating medical procedure (intubating, nebulizing therapy)
what is airborne transmission?
microorganisms contained in aerosolized secretions (person-air-person) secretions over short or long distances and must be inhaled by a susceptible host ex: coughing, sneezing, singing, AGMP’s
what is an AGMP?
aerosol generating medical procedure
what are some examples of pathogens that spread airborne?
TB, varicella, measles
how long can the measles virus be active airborne for?
90 minutes
what is common vehicle transmission?
transmission from a single contaminated source (contaminant to person) ex: ecoli from water
what are some pathogens that are transmitted via common vehicle transmission?
ecoli, salmonella, pseudomonas
what is vectorborne transmission?
transmission via vectors (living organisms), (animal/insect to person) ex: mosquitos, flies, mice
