Half a year fleeing the new coronavirus and the science that explains it is far from consensus. One of the most controversial issues is the routes of transmission of the virus. For the World Health Organization (WHO), the main route of contagion is those virus-laden droplets that escape with coughs, sneezes, etc. and end up in the mouth, eyes and nose of another person. Hence the safety distance, masks and hand washing. But for months, experts in airborne infections have been demanding that the WHO assume that These viruses also remain suspended in microscopic particles and end up being breathed in by someone nearby after a few minutes.. Now, 239 specialists publish an open letter to health authorities in which they assure that “there is more than enough evidence for the precautionary principle to be applied. To control the pandemic, while waiting for a vaccine to be available, all transmission routes must be interrupted.”
