People ask different questions like; Is Coronavirus Airborne or droplet or not?, in better understanding of the virus transmission.
The World Health Organization (WHO) has debunked the myth which suggested that COVID-1 is airborne and can remain in the air for 8 hours.
According to current evidence, COVID-19 virus is transmitted between people through respiratory droplets and contact routes.
Droplet transmission occurs when a person is in in close contact (within 1 m) with someone who has respiratory symptoms (e.g. coughing or sneezing,) and is therefore at risk of having his/her mucosae (mouth and nose) or conjunctiva (eyes) exposed to potentially infective respiratory droplets (which are generally considered to be > 5-10 μm in diameter). Droplet transmission may also occur through fomites in the immediate environment around the infected person.7 Therefore, transmission of the COVID-19 virus can occur by direct contact with infected people and indirect contact with surfaces in the immediate environment or with objects used on the infected person (e.g. stethoscope or thermometer).
Airborne transmission is different from droplet transmission as it refers to the presence of microbes within droplet nuclei, which are generally considered to be particles < 5μm in diameter, and which result from the evaporation of larger droplets or exist within dust particles. They may remain in the air for long periods of time and be transmitted to others over distances greater than 1 m.
WHO Says ; airborne transmission may be possible in specific circumstances and settings in which procedures that generate aerosols are performed but In analysis of 75,465 COVID-19 cases in China, airborne transmission was not reported.
WHO concluded in its tweet, that the virus is mainly transmitted through droplets generated when an infected person coughs, sneezes or speaks. It added that the droplets are too heavy to hang in the air and falls quickly on the floor and surfaces.
WHO continues to recommend droplet and contact precautions and a 1m distance from other people, disinfecting surfaces, washing of hands.
