What is the most effective way to prevent infection?

Hand washing is the single most effective way to prevent the spread of infections. You can spread certain “germs” (a general term for microbes like viruses and bacteria) casually by touching another person.

Is TB airborne or droplet?

What are the three types of transmission based precautions?

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. Transmission can be by direct or indirect contact or through airborne transmission.
