Corona virus spreads through spitting. In India, there have been cases where 3 people have got contagious to this deadly virus. As the virus is in the air and as you produce more saliva with chewing, the virus from the air finds it suitable habitable place and it gets transmitted through the trachea of the person.
It gets into the esophagus and into the food pipe. When you chew and spit, it gives virus the new fresh layer to get attached and grow.
During the incubation period it spreads throughout the body, giving a warmth feeling. After 15 days, it brings out the symptoms in the form of fever and cough .
History of Corona Virus
The official story is that this new corona virus emerged from a Wuhan wet market, where live animals that would never normally meet in the wild live side by side, facilitating trans-species mutation of pathogens. It came from Chinese market into the Indian market through import of meat.
Yet the first three known cases from Dec. 1 and 2 were not linked to the market. Neither were 11 more cases of the 41 reviewed in the recent study. This early data suggests an evolving virus that surfaced considerably earlier. Undetected among the plethora of similar chest infections and common symptoms, it honed its capacity to spread from human to human.
As happened with SARS, new corona may be mutating along the way, gradually becoming more virulent.
About Corona Virus
The corona virus is a physically large virus—in relative terms, at just 125 nano meters with a surface of spike projections, too big to survive or stay suspended in the air for hours or travel more than a few feet.
Like influenza, this corona virus spreads through both direct and indirect contact. Direct contact occurs through the physical transfer of the microorganism among friends and family through close contact with oral secretions. Indirect contact results when an infected person coughs or sneezes, spreading corona virus droplets on nearby surfaces, including knobs, bed rails, and smartphones.
As with SARS, droplets generated during medical procedures such as bronchoscopy and respiratory treatment may be aerosolized, infecting multiple medical staff and enabling super-spreading.
Hand hygiene, avoid spitting and personal protective barriers—gowns, gloves, masks, and goggles—reduce droplet transmission. The incubation period, however, is unknown but currently very roughly estimated as between one and 14 days.
