MANILA — The above photo-article was taken from the Viber Group Chat of health workers connected with the Department of Health, posted here in an effort to quell raging arguments on how COVID-19 are transmitted.
The World Health Organization also issued a scientific brief below for our guidance:
“According to current evidence, COVID-19 virus is transmitted between people through respiratory droplets and contact routes.1-6
Droplet transmission occurs when a person is 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.” (ia/sovereignph.com)
