Air borne, also called by droplets, by fecal oral route, by direct physical contact or by way of infected cloths etc, sexually transmitted and vector borne are the five modes … of disease transmission. 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.

Transmission: Person to person by direct contact with another person with a purulent lesion or purulent discharge or from a person with asymptomatic carriage (colonisation).

Direct transmission is the transfer of an infectious agent directly into the body. In the 16th century, most people believed that disease was spread by foul air. There were no microbes, germs, or viruses – just air that had lost its ability to keep people healthy. So strong was this belief, that the Italian phrase for bad air, “malaria” was used to identify a common blood disease.

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. For example, a person cannot get infected from touching, kissing or having sex with a person who has Lyme disease. During Pregnancy & While Breastfeeding.
