    Study Notes

    Infection and Its Occurrence

    • Infection is the invasion and multiplication of pathogenic microorganisms in the body, which can lead to disease
    • For infection to occur, three necessary factors must be present: a pathogenic microorganism, a susceptible host, and a portal of entry into the host

    Colonization and Symptomatic Infection

    • Colonization refers to the presence and multiplication of microorganisms on or within the body, but without causing disease or symptoms
    • A symptomatic infection occurs when the colonization of microorganisms leads to signs and symptoms of disease, such as fever, pain, or inflammation

    Infection Prevention and Control

    • The most important technique in preventing and controlling transmission of infection is proper hand hygiene, including hand washing and use of hand sanitizers
