Corona Virus Spread /Airborne Virus

corona virus spread through air 

                                                                       We've all been told to cough and sneeze into our elbow and keep a distance from others, but can those with COVID-19 pass it onto others just by breathing and talking? In other words, can it become airborne?

There's been a lot of talk about this the past week - but it's a complicated question, and the answer depends on who you ask.

When a sick person coughs or sneezes, large droplets fly through the air and can infect people nearby (usually under a metre or so but sometimes across much larger distances).

The virus that causes COVID-19 is mainly transmitted through droplets generated when an infected person coughs, sneezes, or speaks. These droplets are too heavy to hang in the air. They quickly fall on floors or surfaces. You can be infected by breathing in the virus if you are within 1 metre of a person who has COVID-19, or by touching a contaminated surface and then touching your eyes, nose or mouth before washing your hands.

                                            We know that the virus's main route of transmission from one person to another is through droplets which are sneezed or coughed out by infected people. A single cough of corona virus patient can produce up to 3,000 droplets, while a sneeze can produce as many as 10,000.

These droplets of coronavirus patient then land in or are breathed into another person's airways, or fall on a surface that is touched by an uninfected person, who then touches their face - specifically their mouth, nose, ears or eyes.

This method of transmission is known as "droplet spread". While it is in these droplets, the coronavirus is only in the air for a short time and travels only a short distance before it is pulled down by gravity after being coughed or sneezed out.  

                                                               Respiratory infections can be transmitted through droplets of different sizes: when the droplet particles are >5-10 μm in diameter they are referred to as respiratory droplets, and when then are <5μm in diameter, they are referred to as droplet nuclei.¹ According to current evidence, COVID-19 virus is primarily transmitted between people through respiratory droplets and contact routes.
