How to spread?

Broadcast pathway is multi-faceted, there are mainly the following types:

(1) contact transmission: is a common mode of transmission of hospital infections, according to the pathogens leave the infectious agent to invade the body before and after the stay in the external environment, can be divided into direct contact transmission and indirect contact transmission. Direct contact transmission refers to the direct contact between the susceptible person and the infectious agent, which leads to infection without the help of transmission factors. Indirect contact transmission refers to the participation of transmission factors, that is, transmission factors carrying pathogens and susceptible to contact, the pathogen into the susceptible.

(2) airborne transmission: the air as a medium, the micro-particles with pathogens (droplet nuclei, bacterial dust), with the flow of airflow and cause infection, also known as microbial aerosol transmission.

(3) media transmission: it is the transmission caused by contamination of some of the items used in the hospital **** (food, water, blood and blood products, drugs and various preparations and medical devices, etc.) by pathogenic microorganisms, also known as **** with the media transmission.

(4) biological vector transmission: mainly refers to the vector arthropods (mosquitoes, fleas, lice, flies, ticks).
