Transmissible diseases

Aedes aegypti
Ixodes ricinus

Transmissible infections are vector-borne infections. The most common vector is arthropods that inoculate infectious agents into the human body. Vector transfer can be:

  • mechanical – the etiological agent is in the gut or on the body surface of the vector and does not multiply, most often it is transmitted by food, such as salmonella, shigella or enteroviruses;
  • biological – in this case the pathogen multiplies in the vector and is subsequently transmitted most often by the mechanism of inoculation, this type of transmission occurs, for example, in the case of malaria, yellow fever, or borreliosis

Human transmissible infections are characterized by:

  • disease vector (for example mosquito, tick, louse, fly);
  • pest reservation (for exapmle the animal species from which the vector obtains the infectious agent).
  • responsive object (especially human)
