Who walking down the street remembers that person who coughed or sneezed as he passed by? And we immediately wondered if that sneeze had an effect on us. But have we ever wondered what is more dangerous and infects more a sneeze or a cough?
A speed comparison
A Virginia Tech research in America, he put a sneeze and a cough on the test bench. Which of the two has the ability to cast faster and cover a longer distance? The thing is not trivial, especially in this period of Covid 19, because it seems that the particles travel in the air and the smallest ones also remain suspended.
Well, the competition between sneezing and coughing was won by the first. The sneeze in fact projects about 40,000 particles from the mouth at a speed of 160 km / h, up to 10 m away. While the cough emits about 3,000 particles at the speed of 80 km / h.
Difference between open and closed places
Sneezing and coughing have a different danger, according to the places in which they emit. If we are on the street, the particles will be dispersed more or less quickly and the contagion could affect the very moment in which they are emitted.
If you are in a closed place things change. The smallest particles remain suspended in the air for a long time with a fairly high capacity to infect. The heaviest ones, on the other hand, fall a short distance away, being able to finish their run on tables, chairs and other objects that we can touch with our hands.
Have we ever wondered what is more dangerous and more contagious than a sneeze or a cough?
The only way to avoid the almost sure contagion, when you are indoors, is to ventilate the rooms often, practically creating those open air conditions found on the streets.
Here are some simple tips to avoid contamination with this dangerous virus.
