The way it is transmitted coronavirus inside like a living room of the house, one Pub and one school classroom Depending on the application or not of the security measures, try to capture graphics produced by the Spanish newspaper The country using a model developed by the chemist Jose Luis Jimenez at the University of Colorado.
At first it is recalled that experts have devised three ways to transmit the virus: the first has to do with drops expelled during speech or coughing, the latter has to do with contaminated surfaces, although it is not considered the most likely version, and the third with aerosols, that is, the inhalation of particles of a coronavirus vector.
In the living room
The script of room It includes six people who are in the same room with one of them being positive for the coronavirus as in Spain it is estimated that 31% of infections were transmitted in this way between family and friends.
After four hours and if none of the five healthy people wears a mask and if there is no ventilation, all five will become ill.
If at the same time the five healthy clothes mask so all four are still at risk of getting sick.
However, if everyone wears a mask, there is ventilation, and the common presence in the space is cut in half, then only one in five healthy people is at risk of getting sick.
At the bar
The experiment in Pub, in places, that is, according to data from Spain can cause up to 27 infections if there is an “explosion”, it begins at 7 pm.
The capacity of the bar is reduced to 50%, there are 15 customers and three employees, the windows are closed and there is no ventilation. After six hours without security measures, 14 of the clients will be infected.
With continuous use of the mask, the number of cases is reduced to 8. However, if there is the combination of ventilation, masks and a shorter stay indoors, the number of possible cases is reduced to one person!
To school
The script in school begins with the assumption that “patient zero” is educational. As El País points out, the risk of transmitting the virus is greater in this scenario since the teacher is forced to speak more and several times louder to be heard.
If they spend two hours in a room with 24 students and a virus educator, and without masks, there is a risk of infecting 12 children.
If everyone wears a mask for the same amount of time, the number of students at risk of becoming infected drops to five.
By ventilating the room and reducing your stay in it by one hour, there is a risk of infection for a single student.
