air sprays

In internal atmospheres air sprays are accumulated if there is not a suitable ventilation, for this reason the risk of contagion of COVID-19 in these atmospheres is higher than the risk in the exterior and authorities inform that it is always preferable to carry out all activities that is been able to in the exterior.

To reduce the amount of generated air sprays we must limit seating capacities in the closed spaces, to use masks, to lower conversations and the tone. And to control the risk of contagion, control measures involve: use the well-matched mask, to reduce the time of permanence in the closed space, to increase the interpersonal distance and, topcoat, to ventilate (to contribute new and clean air) to delete or to reduce the presence of air sprays in the atmosphere.

The World Health Organization (WHO) has elaborated a video where the importance of the control is explained of the via of airborne transmission through a suitable ventilation.
