You are more likely to get Covid of someone who does what cough
The most banal activity could ask you and other people at risk, a new study has been found.
Although our comprehension of Covid and how it is transmitted has evolved over the last year, a solid consensus has emerged at first than aerosols, which means contaminated droplets, are the most common way, the viruses spread from person to person. So, if you have been around someone who coughs over the last 10 months, you have probably found it quickly safeguarding for fear of being infected with Covid-19. But now, a new study published in the journalActs of the Royal Society A January 20 found that a behavior we all do on the fact every dayjust as likely to spread Covid Like cough, if not more and it's just talking.

Droplets Propagation to talk tend to stay in the air longer and travel father.
The research team behind the new study led by the Prof. Author.Pedro Magalhães de Oliveira, A fluid mechanics expert in the Engineering Department of Cambridge University created a mathematical model to predict how Covid spreads an infected person in a room, taking into account the size of the space, the Number of people present, ventilation, and if people wore masks.
The hypothesis could be that actions that propagate a lot of droplets like sneezing, cough, or cries in terms of the risky Covid transmission, but this new research from the University of Cambridge and the Imperial College From London suggests the opposite. The largest droplets associated with the cough fell on the ground at a distance and at a faster rhythm shorter, while the smallest droplets produced by speaking transported the virus more than 6.5 feet and listed in a room for a more long period of time.
"Speaking is a very important question which must be taken into account because it produces much thinner particles than [cough] and these particles or aerosols, may be suspended for more than one hour in sufficient quantities to cause the disease, "said OliveiraThe Guardian. And to learn more about COVID transmission, seeThe strange new way you could get Covid, the study says.
Without other security measures involved, COVID is more likely to spread by talking.
The study revealed that when you are in a poorly ventilated space and do not wear masks, speak is much more likely to spread the virus than a little cough. In a modeled scenario, the researchers found that after a short cough, the number ofInfectious particles in the air fell after 1 to 7 minutes, sciences live notes. But after talking for 30 seconds, it was necessary to fall at 30 minutes to levels for the number of infectious particles. After an hour, a large number of particles were still suspended in the air, enough to make someone else.

The more you spend talking to an infected person, the better your risk.
If you are in a badly ventilated room with an infected person who speaks, you have as much risk of 20 percent infection, the researchers found. "This analysis illustrates the risk associated with constant speak in closed environments (such as, in a conference room) due to a higher mass fraction of liquid resulting in small droplets during the language," scientists have concluded.

Ventilation and multilayer masks are essential to stay safe.
The Cambridge team says "ventilation ... is of paramount importance to minimize the inside of the risk of infection. In a statement, Oliveira stated that the study shows "how these littleDroplets can accumulate in interior spaces In the long run, and how this can be attenuated with adequate ventilation ".
The team also used the results to build aOnline CalculatorWho helps users can assess the risk of different situations inside considering the size of a room and the number of people there. If you spend an hour in a medium-sized store with a capacity of 50 people, for example, the improvement of ventilation or portThree folds masks Can see your risk of decreasing the infection of 8 percent to 2 percent.
"The idea is not to obtain the absolute risk figures of the tool, but use it to see how the impact attenuation strategies of the infection," said OliveiraThe Guardian. And for more place where the Covid epidemic is the worst right now, seeThat's how the COVID epidemic is in your state.
