Some infectious diseases can be spread via respiratory droplets expelled from the mouth and nose, as when a person sneezes. 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 ...
Airborne diseases can be transmitted from one individual to another through the air. The pathogens transmitted may be any kind of microbe , and they may be spread in aerosols, dust or droplets. The aerosols might be generated from sources of infection such as the bodily secretions of an infected individual, or biological wastes.
The flu is spread from person to person, mainly by droplets made when people who have it cough, sneeze or talk, according to the Centers for Disease Control and Prevention. The droplets can land ...
An infectious disease agent can be transmitted in two ways: as horizontal disease agent transmission from one individual to another in the same generation (peers in the same age group) [3] by either direct contact (licking, touching, biting), or indirect contact through air – cough or sneeze (vectors or fomites that allow the transmission of the agent causing the disease without physical ...
Mycoplasma pneumonia is caused by a bacterium that can spread through droplets when an infected person coughs or sneezes. ... Infectious disease experts said the outbreaks are cause for increased ...
The transmission of COVID-19 is the passing of coronavirus disease 2019 from person to person. COVID-19 is mainly transmitted when people breathe in air contaminated by droplets/aerosols and small airborne particles containing the virus.
In humans, influenza viruses are primarily transmitted through respiratory droplets from coughing and sneezing. Transmission through aerosols and surfaces contaminated by the virus also occur. Frequent hand washing and covering one's mouth and nose when coughing and sneezing reduce transmission, as does wearing a mask.
However, like most bacterial systemic diseases, the disease may also be transmitted through an opening in the skin or by inhaling infectious droplets of moisture from sneezes or coughs. In both cases septicemic plague need not be the result, and in particular, not the initial result, but it occasionally happens that bubonic plague for example ...
