Dr KK Aggarwal, President, Confederation of Medical Association in Asia and Oceania, has said that new studies and a large corona virus outbreak in Massachusetts, US, bring into question reassuring assertions by US officials about the way the novel coronavirus spreads.
So far it is understood that virus is spread mainly by people who are already showing symptoms, such as fever, cough or difficulty in breathing.
But it appears that a Massachusetts coronavirus cluster with at least 82 cases was started by people who were not yet showing symptoms.
More than half a dozen studies have shown that people without symptoms are causing substantial amounts of infection. WHO has so far emphasized that asymptomatic transmission can happen, but have said that it is not a significant factor in the spread of the virus.
“We know that a “naked” virus can’t go anywhere unless it is hitching a ride with a droplet of mucus or saliva. These mucus and saliva droplets are ejected from the mouth or nose as we cough, sneeze, laugh, sing, breathe and talk. If they don’t hit something along the way, they typically land on the floor or ground. To get access to your cells, the viral droplets must enter through the eyes, nose or mouth,” explained Dr Aggarwal.
According to Dr Aggarwal, sneezing and coughing are likely the primary forms of transmission. But talking face-to-face with someone could pose a risk. Even sitting in front of someone who is singing, laughing, shouting or taking a forced large breath can shed the virus in the atmosphere.
He advised that one should maintain a distance of six feet from someone who is singing, do sympathetic breathing yoga only in parks in the sun (Bhastrika and Kapalbharti) to build respiratory capacity.
“The distance between patient and doctors talking to each other should be three feet. Face to face meetings should have a distance of three feet. On should speak softly and not loudly. People should avoid joining laughter clubs in the morning during this period or maintain a distance of six feet between two people,” he explained.
