Direct transmission of disease is by the direct contact of a diseased person,whereas indirect transmission occurs without the direct contact.
For example ;by using anything of diseased person.
indirect contact
A pathogen causes a disease while a contagion spreads a disease by direct or indirect contact.
Alzheimer's disease affects memory while Parkinson's disease affects movement.
An infectious disease resulting from direct or indirect contact between individuals or animals.
The infectious diseases can spread through air, indirect or direct contact and through body fluids like urine and saliva.
indirect transmission of disease through fomites. In this case, the facial tissue acts as a fomite, which is an inanimate object that can carry and transmit infectious agents.
In the context of disease transmission, a reservoir is a place where a pathogen can live and multiply, such as an animal or environment. A vector is an organism that can carry and transmit the pathogen from the reservoir to a host. The relationship between a reservoir and a vector is that the reservoir provides a source of the pathogen, while the vector helps spread the pathogen to new hosts, contributing to the transmission of the disease.
Direct Contact and Indirect Contact
cycle of disease transmission
An "infectious disease" an agent that can be passed from one living organism to another. A non-infectious disease is a disease or other condition that cannot be spread to another organism.
The most prevalent method of disease transmission is hand to mouth. Washing your hands after touching any public space is the single best disease prevention. Other routes of disease communication are food, water, airborne, sexual transmission, blood transmission, etc.
Diffusion of AIDS is an example of contagious diffusion, where the disease spreads through direct or indirect contact between individuals.
