A respiratory droplet is a small aqueous droplet produced by exhalation, consisting of saliva or mucus and other matter derived from respiratory tract surfaces. Respiratory droplets are produced naturally as a result of breathing, speaking, sneezing, coughing, or vomiting, so they are always present in our breath, but speaking and coughing ...
Airborne transmission or aerosol transmission is transmission of an infectious disease through small particles suspended in the air. [2] Infectious diseases capable of airborne transmission include many of considerable importance both in human and veterinary medicine .
airborne transmission – very small dry and wet particles that stay in the air for long periods of time allowing airborne contamination even after the departure of the host. Particle size < 5 μm. droplet transmission – small and usually wet particles that stay in the air for a short period of time. Contamination usually occurs in the ...
An existing model of airborne transmission (the Wells-Riley model) was adapted to help understand why crowded and poorly ventilated spaces promote transmission, [5] with findings supported by aerodynamic analysis of droplet transfer in air-conditioned hospital rooms. [46]
Airborne transmission: Dissemination can be either airborne droplet nuclei (small-particle residue {5 μm or smaller in size} of evaporated droplets containing microorganisms that remain suspended in the air for long periods of time) or dust particles containing the infectious agent. Microorganisms carried in this manner can be dispersed widely ...
Droplet nuclei are formed by the "dried residua of larger respiratory droplets". [2] These particles are "the vehicle for airborne respiratory disease transmission, which are the dried-out residual of droplets possibly containing infectious pathogens". [3] Diseases such as tuberculous and COVID-19 can be transmitted via droplet nuclei. [2] [4]

Contagious diseases can spread to others through various forms. Four types of infectious disease transmission can occur: . contact transmission, which can be through direct physical contact, indirect contact through fomites, or droplet contact in which airborne infections spread short distances,
