droplet nucleus

Airborne transmission: Spread of infection by droplet nuclei or dust through the air.

Some of viruses will become droplet nuclei.

Procedures that induce coughing can increase the likelihood of droplet nuclei being expelled into the air.

Once this mucus shell evaporates the remaining viron is called a droplet nucleus or quanta.

The lower the humidity, the quicker the mucus shell evaporates thus allowing the droplet nuclei to stay airborne and not drop to the ground.

Viral diseases that are commonly spread by coughing or sneezing droplet nuclei include (at least):

When the airplane flies through the super-cooled water droplets, the plane becomes the droplet nucleus, allowing the water to freeze on the surface.

Discussion The majority of rhinoviral transmission among adults is thought to occur via airborne infectious droplet nuclei [ 8 9 10 ] .

When a virus is expelled by a sneeze, its mucous membrane evaporates, and the virus becomes a droplet nucleus which can be inhaled by another person, thus spreading the virulent infection.

TB infection occurs when a susceptible person inhales droplet nuclei containing Mycobacterium tuberculosis organisms, generated when persons with pulmonary or laryngeal TB disease cough, sneeze, shout, or sing (276).

If these droplet nuclei are breathed into nose or mouth of an uninfected person (known as a susceptible) - then the droplet nuclei may penetrate into the deep recesses of their lungs.

Droplet nuclei are an important mode of transmission among many infectious viruses such as Influenza A. When viruses are shed by an infected person through coughing or sneezing into the air, the mucus coating on the virus starts to evaporate.

The low indoor humidity levels in wintertime buildings ensure that higher levels of droplet nuclei will survive: droplet nuclei are so microscopic that they are able to stay airborne indefinitely on the air currents present within indoor spaces.
