Study Notes
Transmission of Pathogens
- Direct person-to-person transmission occurs through direct contact, inhalation of airborne pathogens, or through vectors such as insects.
Sterilization
- Sterilization eliminates all microorganisms, including pathogens and spores, using methods such as heat, radiation, or chemicals.
Reservoirs of Infection
- Reservoirs are sites where pathogens can survive and may or may not multiply, including people, animals, and environment.
Infection Prevention and Control
- Infection prevention and control involves practices to keep disease-producing microorganisms at bay, such as hand hygiene, use of personal protective equipment, and proper cleaning and disinfection.
Healthcare-Associated Infections (HAIs)
- Common HAIs that people may get while receiving care for another condition include urinary tract infections, surgical site infections, bloodstream infections, and pneumonia.
