Disease transmission and cycle SlideShare. Modes of transmission, personal protective equipment, and isolation precautions learning objectives upon completion of this chapter, the reader will be able to: 1. list and define the three main modes of infectious disease transmission. 2. identify various forms of personal protective equipment (ppe). 3. explain the two-tiered approach to preventing the transmission of infectious вђ¦, vectors add an extra dimension to disease transmission. since vectors are mobile, they increase the transmission range of a disease. changes in vector behaviour will affect the transmission pattern of a disease. it is important to study the behaviour of the vector as well as the disease-causing microorganism in order to establish a proper method of disease prevention. in the case of malaria.

  • Routes of disease transmission companion animals pathogenic agents can spread animal-to-animal or animal-to-human by a variety of transmission modes. this handout explains the diff erent methods or routes that dis-ease pathogens can use to circulate among animals or between humans and animals. an understanding of these transmission routes can aid in disease prevention actions. zoonotic qualitative approach is used to rank the possible modes of foot-and-mouth disease virus (fmdv) transmission by relative biologic hazard only. the purpose of the hazard categorization is to better understand the relative importance of fmdv

    To move from host-to-host, protozoan parasites use one of four main modes of transmission: direct, faecal-oral, vector-borne and predator-prey transmission. direct faecal-oral transmission typically through feces of an infected triatomine insect (reduviid bug), may occur when a bug bite is scratched or by consuming food or beverages contaminated with infected bug feces; may also be transmitted through blood transfusion or organ transplantation and from mother to infant.
