Droplet nucleus
Droplet Nucleus
Droplet Nucleus (pronunciation: drɒplɪt 'njuːklɪəs) is a term used in Epidemiology and Microbiology to describe the airborne particles that are capable of carrying infectious pathogens. The term is often used in the context of Disease Transmission and Infection Control.
Etymology
The term "Droplet Nucleus" is derived from the words "droplet", which refers to a small drop of liquid, and "nucleus", which in this context refers to the core or central part. The term is used to describe the core of a droplet which, in the context of disease transmission, can carry infectious agents.
Definition
A Droplet Nucleus is a residue or dried droplet produced during the evaporation of fluid in which microorganisms are present. These particles, which are typically less than 5 micrometers in diameter, can remain suspended in the air for extended periods and can be inhaled by individuals, potentially leading to infection.
Related Terms
- Aerosol: A suspension of fine solid particles or liquid droplets in air or another gas. Droplet nuclei are a type of aerosol.
- Airborne Transmission: The spread of an infectious agent caused by the dissemination of droplet nuclei that remain infectious when suspended in air over long distances and time.
- Respiratory Droplets: Droplets produced when an infected person coughs, sneezes, talks, or exhales. These droplets can contain infectious agents and can be a source of droplet nuclei.
