    Study Notes

    Infections

    • Infection is the invasion of a host organism's bodily tissues by disease-causing organisms, their multiplication, and the reaction of host tissues to these organisms and the toxins they produce.

    Definitions

    • Disease: Any deviation from a condition of good health and well-being.
    • Infectious Disease: A disease condition caused by the presence or growth of infectious microorganisms or parasites.
    • Pathogenicity: The ability of a microbe to cause disease.
    • Virulence: The degree of pathogenicity in a microorganism.

    Types of Infections

    • Acute Infection: Sudden onset, rapid progression, and often with severe symptoms.
    • Chronic Infection: Delayed onset and slow progression.
    • Primary Infection: Develops in an otherwise healthy individual.
    • Secondary Infection: Develops in an individual who is already infected with a different pathogen.
    • Localized Infection: Restricted to a specific location or region within the body of the host.
    • Systemic Infection: Spread to several regions or areas in the body of the host.
    • Clinical Infection: An infection with obvious symptoms.
    • Subclinical Infection: An infection with few or no obvious symptoms.
    • Opportunistic Infection: Caused by microorganisms that are commonly found in the host’s environment.

    Causative Agents

    • Bacteria
    • Viruses
    • Fungi
    • Protozoa
    • Helminths
    • Prions

    Epidemiology

    • The study of the transmission of disease.
    • Communicable Disease: A disease that can be transmitted from one individual to another.
    • Contagious Disease: A communicable disease that is easily spread from one individual to another.
    • Noncommunicable Disease: A disease that is not transmitted from one individual to another.
    • Endemic Disease: A disease condition that is normally found in a certain percentage of a population.
    • Epidemic Disease: A disease condition present in a greater than usual percentage of a specific population.
    • Pandemic Disease: An epidemic affecting a large geographical area; often on a global scale.

    Reservoir of Infection

    • The source of an infectious agent.
    • Carrier: An individual who carries an infectious agent without manifesting symptoms, yet who can transmit the agent to another individual.
    • Fomites: Any inanimate object capable of being an intermediate in the indirect transmission of an infectious agent.

    Human Reservoirs

    • Persons with acute or subclinical illness.
    • Carriers: during incubation, convalescent carriers, chronic carriers, and intermittent carriers.

    Nature of Microorganisms

    • Microorganisms are small, living organisms that are not visible to the naked eye.
    • Pathogens: Microorganisms that can cause disease.
    • Non-pathogens: Microorganisms that do not cause disease; can be beneficial.
