Latin, inficere = infect.
  • Alimentary infections:

    Parasites are inside food.

  • Autoinfections:

    Repeated self-infection with parasites of the same host.

  • Endogenous infections:

    Parasites wander from one organ to another inside the same host.

  • Exogenous infections:

    Parasites enter from outside the body.

  • Inapparent infections:

    Parasites do not induce clearly remarkable symptoms.

  • Horizontal infections:

    Transmission of parasites between hosts of the same generation/group.

  • Iatrogenic infections:

    In this case the medical doctor or veterinarian transports a parasite from one group of patients to another.

  • Inoculative infections:

    Agents are transmitted by bites of vectors.

  • Connatal infections:

    Infections during birth.

  • Contaminative infections:

    Infections due to infectious stages, e.g., in feces, blood, etc.

  • Latent infection:

    Infections with no detectable symptoms (e.g., due to lack of methods).

  • Neonatal infections:

    Infections of newborn animals or humans.

  • Peroral infections:

    Infections by oral uptake.

  • Percutaneous infections:

    Infections by penetration of the skin.

  • Perinatal infections:

    Infections in the periods before and after birth.

  • Phageous infections:

    Hosts ingest occasionally infected vectors.

  • Prenatal infections:

    Infections of the fetus inside the placenta.

  • Primary infections:

    First infection.

  • Reinfections:

    Repeated infections.

  • Recidive infections:

    Infections, which show again symptoms of disease when hosts suffer from phases of immunosuppression.

  • Secondary infections:

    Infections of a host which has already another infection.

  • Superinfections:

    Repeated infections with the same parasite from another host.

  • Transmammal infections:

    Infections of babies due to drinking of mother’s milk.

  • Vertical infections:

    Infections are transmitted from one host generation to the next one.
