Mode of Transmission for Acute Diarrheal Disease. 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, scapularis ticks are known to transmit Lyme disease. Other Modes of Transmission Person-to-Person There is no evidence that Lyme disease is transmitted from person-to-person.

A method of transmission is the movement or the transmission of pathogens from a reservoir to a susceptible host. Once a pathogen has exited the reservoir, it needs a mode of transmission to the host through a portal of entry.

Whether the transmission of a viral pathogen leads to the manifestation of the disease is determined by the intricate interplay of a multitude of still largely undefined viral and host factors.
