Aspesis
Practice reducing or eliminating pathogens
Disinfecting
Destroys pathogens except spores
Cleaning
Reducing microbes, visible contaminates
Decontamination
Cleaning, disinfecting, sterilizing
Sterilization
Eliminating pathogens, including spores
Risk factor for infection
Age, nutrition, open wound
Multi drug-resistant organism
Resistant to more then one antibiotic
Vector
Insects, animals
Droplet
Large particles-sneeze
Airborne
Small particles, travel far on dust
Contact
Touch
Four moments of hand hygiene

Nausea
Vomiting
Diarrhea

Parasite
Live off another living organism
Fungi

Virus
Infect living cells and take over
Three possible outcomes to exposure to pathogen
The immune system destroys the pathogen,
The immune system does not destroy the pathogen but infection does not develop,
Infection develops
Communicable phase
The time during the person is at risk of transferring the pathogen to others
Our protection against viruses happen
Virus mutating some protein, the proteins are recognized and you get over the virus faster
Isolation precautions
Are guidelines to prevent the spread of pathogens
