What is an infection?

Microorganisms penetrate.
An infection remain generally means the transfer, adhesion and penetration of microorganisms into a macro-organism. Specifically this means that bacteria, viruses, fungi, worms and protozoa (microorganisms) penetrate into a human, an animal or a plant (macro-organism), and multiply there. Infections cause an inflammatory reaction.


The disease is determined by the pathogen.
Infection is the precondition for the emergence of infectious diseases such as mumps, tuberculosis or syphilis. We, the disease is essentially determined by the properties of the pathogen. Whether and how hard runs an infectious disease that is associated with susceptibility and immunity of the respective human (or other macro-organisms).


A division is often useful when one wants to determine differences observed.
One can divide the various agents of infection by different aspects:

    Ports of entry:
    a) percutaneous skin (), mucosal (permukös) or respiratory (inhalation infection). These entry points are combined parenterally with the term.
    b) gut (enteral)
    c) wounds

    Transmissibility of the pathogen:
    a) directly from person to person
    b) indirectly via intermediate carrier or the intermediate hosts, such as ticks infections

    Time sequence of symptoms:
    a fulminant): Rapid onset of severe course, often fatal.
    b) acute: Sudden. Beginning with feverish over the course of days.
    c) chronic: Gradual start with a slightly feverish course over weeks, months or years.
    d) Recurrent: recurrent, usually with acute febrile episodes is running.
    e) latent: Silent periods without symptoms for months or years.

    Pathogens:
    a) Viruses
    b) Bacteria
    c) fungi (mycoses)
    d) protozoan infection such as amoebiasis

    Immune status:
    a) opportunistically on the basis of a disturbed immune system (eg HIV infection, malignancy)
    b) without being effectively inapparent immune disease symptoms
