What are the most common mode of transmission of infection in healthcare settings?

This is probably the most common mode of transmission in health-care settings. Droplet transmission: Respiratory droplets carrying pathogens are generated when an infected person coughs, sneezes, or talks, as well as during procedures such as suctioning or intubation.

What is the most common form of transmission of microorganisms?

Contact transmission is the most common form of transmitting diseases and virus. 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.
