A group of scientists published a letter asking the World Health Organization (WHO) to Investigate the aerial transmission of the Covid-19 and they assured that the standards of social distance are not enough.
The letter, sent by 239 scientists, asked the medical community and international organizations to recognize the risks of transmission of Covid-19 at less than two meters, established as a social distance by most countries.
“We make a call to recognize the Covid-19 aerial extension potential“The experts said, pointing to WHO for failing to” recognize airborne transmission “except for certain hospital procedures.
“Studies have shown, beyond reasonable doubt, that viruses are released during expiration, speaking and coughing in microdrops small enough to stay in the air and pose a risk of exposure at a distance greater than 1 or 2 meters, “they point out.
The warning ensures that “at typical interior speeds, a five micron drop (one micron is one millionth of a meter) travels tens of meters“, covering the entirety of a medium-sized room.
The scientists, which include experts in epidemiology, virology, or fluid physics, rely on research into cases of “supercontamination” of the SARS-CoV-1 virus, responsible for the 2003 SARS epidemic, but also for the SARS-CoV-2 , causing the current pandemic.
“The problem is especially acute indoors or indoors, particularly in those with crowds and inadequate ventilation relative to the number of occupants and for long periods of exposure, “they explained.
