  2. Infection - Wikipedia

    en.wikipedia.org/wiki/Infection

    Chain of infection; the chain of events that lead to infection. There is a general chain of events that applies to infections, sometimes called the chain of infection [14] or transmission chain. The chain of events involves several steps – which include the infectious agent, reservoir, entering a susceptible host, exit and transmission to new ...

  3. Outline of infectious disease concepts - Wikipedia

    en.wikipedia.org/wiki/Outline_of_infectious...

    The following outline is provided as an overview of and topical guide to concepts related to infectious diseases in humans.. Infection – transmission, entry/invasion after evading/overcoming defense, establishment, and replication of disease-causing microscopic organisms (pathogens) inside a host organism, and the reaction of host tissues to them and to the toxins they produce.

  4. Pathogen transmission - Wikipedia

    en.wikipedia.org/wiki/Pathogen_transmission

    An infectious disease agent can be transmitted in two ways: as horizontal disease agent transmission from one individual to another in the same generation (peers in the same age group) [3] by either direct contact (licking, touching, biting), or indirect contact through air – cough or sneeze (vectors or fomites that allow the transmission of the agent causing the disease without physical ...

  6. Latent period (epidemiology) - Wikipedia

    en.wikipedia.org/wiki/Latent_period_(epidemiology)

    The infection of a disease begins when a pathogenic (disease-causing) infectious agent, or a pathogen, is successfully transmitted from one host to another. [3] Pathogens leave the body of one host through a portal of exit , are carried by some mode of transmission and after coming into contact (exposure) with a new susceptible host, they enter ...

  7. Pathogen - Wikipedia

    en.wikipedia.org/wiki/Pathogen

    In biology, a pathogen (Greek: πάθος, pathos "suffering", "passion" and -γενής, -genēs "producer of"), in the oldest and broadest sense, is any organism or agent that can produce disease. A pathogen may also be referred to as an infectious agent, or simply a germ. [1] The term pathogen came into use in the 1880s.

  8. Serial interval - Wikipedia

    en.wikipedia.org/wiki/Serial_interval

    The serial interval in the epidemiology of communicable (infectious) diseases is the time between successive cases in a chain of transmission. [1]The serial interval is generally estimated from the interval between clinical onsets (if observable), in which case it is the 'clinical onset serial interval'.

  9. Fomite - Wikipedia

    He agreed, citing Rao, Fenner and others, that “careful epidemiologic investigation rarely implicated fomites as a source of infection”; and broadly agreed with current recommendations for control of secondary smallpox infections, which emphasized transmission via “expelled droplets” upon the breath. He noted that shed scabs (which ...
