The transmission of microorganisms can be divided into the following five main routes: direct contact, fomites, aerosol (airborne), oral (ingestion), and vectorborne.
What are the 6 main methods of disease transmission?
Students learn about different kinds of disease transmission using an infographic and a reading that describe the following types of transmission: direct, indirect, fecal-oral, droplet, airborne, vector.
What are the 4 most common ways of disease transmission?
The modes (means) of transmission are: Contact (direct and/or indirect), Droplet, Airborne, Vector and Common Vehicle. The portal of entry is the means by which the infectious microorganisms gains access into the new host. This can occur, for example, through ingestion, breathing, or skin puncture.
What is a method of 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.
What are two methods of disease transmission?
There are two types of contact transmission: direct and indirect. Direct contact transmission occurs when there is physical contact between an infected person and a susceptible person. Indirect contact transmission occurs when there is no direct human-to-human contact.
What are the different methods of infection?
The main routes that infection enters the body are through the air, through touch, through bodily fluids, through ingestion or through bites from other living creatures.
How are diseases transmitted?
Infectious diseases commonly spread through the direct transfer of bacteria, viruses or other germs from one person to another. This can happen when an individual with the bacterium or virus touches, kisses, or coughs or sneezes on someone who isn’t infected.

What are various modes of transmission of communicable disease?
A communicable disease is one that is spread from one person to another through a variety of ways that include: contact with blood and bodily fluids; breathing in an airborne virus; or by being bitten by an insect.
What are five 5 factors that can increase an individual’s susceptibility to pathogens?
We all have different susceptibility
Multiple innate factors (e.g., age, nutritional status, genetics, immune competency, and pre-existing chronic diseases) and external variables (e.g., concurrent drug therapy) influence the overall susceptibility of a person exposed to a virus.
