What are three methods of disease transmission?

The mode of transmission can include direct contact, droplets, a vector such as a mosquito, a vehicle such as food, or the airborne route.

What are the 5 methods of disease transmission?

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 four methods 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.

What is the 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.
