A common form of transmission is by way of respiratory droplets, generated by [[coughing]], [[sneezing]], or talking. Respiratory droplet transmission is the usual route for respiratory infections. Transmission can occur when respiratory droplets reach susceptible mucosal surfaces, such as in the eyes, nose or mouth. This can also happen indirectly via contact with [[Fomite|contaminated surfaces]] when hands then touch the face. Before drying, respiratory droplets are large and cannot remain suspended in the air for long, and are usually dispersed over short distances.<ref name=nhmrc/> The size of the particles for droplet infections are > 5 μm.<ref name=":0" />

Organisms spread by droplet transmission include respiratory viruses such as [[influenza virus]], [[parainfluenza virus]], [[adenoviruses]], [[rhinovirus]], [[respiratory syncytial virus]], [[human metapneumovirus]], ''[[Bordetella pertussis]]'', [[pneumococci]], [[streptococcus pyogenes]], [[diphtheria]], [[rubella]],<ref>{{cite web|url=http://www.rightdiagnosis.com/d/diseases_contagious_from_droplets/basics.htm|title=What is Diseases contagious from droplets?|url-status=live|archive-url=https://web.archive.org/web/20150716185815/http://www.rightdiagnosis.com/d/diseases_contagious_from_droplets/basics.htm|archive-date=16 July 2015}}</ref> and [[coronaviruses]].<ref name="WHO">{{cite web |title=Pass the message: Five steps to kicking out coronavirus |url=https://www.who.int/news-room/detail/23-03-2020-pass-the-message-five-steps-to-kicking-out-coronavirus |website=www.who.int |access-date=24 March 2020 |language=en}}</ref> Spread of respiratory droplets from the wearer can be reduced through wearing of a [[surgical mask]].<ref name="canada"/>
