When news of the expansion of Covid-19 began to arrive, it went almost unnoticed that it was being kept in one of the toilets that had been used to confine people in China who had been infected by a floating cloud of coronavirus droplets. This could lead to the conclusion that, under certain humid conditions, Covid-19 could remain floating in the air and continue to be effective in terms of infection.
This week, news from around the world seems to corroborate this suspicion, although with data that makes it irrefutable. Scientists at the University of Florida have detected infectious coronaviruses within five metres of a sick person, which would be telling us that the infectious potential of the airborne coronavirus is much greater than previously thought. Until now, it was assumed that the repsiratory droplets have a diameter of 5 thousandths of a millimetre, as they are, but they could only have a range of approximately 1.5 metres. However, this new discovery seems to indicate that when they fall to the ground, they produce a dissolution by aerosols, which would reduce their weight and therefore they could move through the air much further than was assumed.
The health authorities are now giving precise indications on how to manage ventilation in enclosed places to avoid the incidence of infection. In the next few days in Biosalud we will compile some of these indications in case you want to take them into account. For any precaution is insufficient in the face of this pandemic that is tragically approaching a million victims worldwide.
