However our understanding of COVID and how it has evolved over the past year has led to a solid consensus that aerosols, which means contaminated droplets, are the most common way for the virus to spread from person to person. is. So, if you have been around someone in the last 10 months, you are likely to get yourself back quickly for fear of getting infected with COVID-19. But now, a new study is published in the journal Proceedings of the Royal Society A. On January 20 it has been found that one behavior that we are all dealing with daily is likely to spread COVID in the form of a cough, if not more – and it is the simple act of talking.
Read on to find out what this new research has discovered, and what you can do to avoid the virus, stop doing it immediately to avoid the new COVID strain, Doctor Warne.
The droplets from talking keep hanging in the air for a long time and travel father.
The research team behind the new study- lead author Prof. Pedro Magalehas de Oliveira, An expert in fluid mechanics in the Engineering Department at the University of Cambridge, created a mathematical model to predict how COVID spreads from an infected person in a room, taking into account the size of the space, the number of attendees, ventilation, And people wore masks or not.
The notion that actions that spill a lot of drops – such as sneezing, coughing, or yelling – is the most risky in terms of COVID broadcasts, but new research from the University of Cambridge and Imperial College suggests not otherwise. Large drops associated with cough fall to the ground at a short distance and at high speeds, while small droplets caused by talking cause the virus to exceed 6.5 feet and last longer in a room.
“Speaking is a very important issue to consider because it produces very fine particles. [than coughing] And these particles, or aerosols, can be suspended for more than an hour enough to cause disease, “de Oliveira reported Guardian. And for more information about COVID transmission, The Strange New Way, you can call COVID, Study Sage.
Without other safety precautions in the game, talking in COVID is more likely to spread.
The study found that when you are in a poorly ventilated place and do not wear masks, talking increases the likelihood of the virus coughing less. In a modeling scenario, researchers found that after a small cough, the number of infectious particles in the air fell after 1 to 7 minutes, Live Science notes. But after speaking for 30 seconds, it took 30 minutes for the number of infectious particles to fall to the same level. After an hour, a high number of particles were still suspended in the air, enough to make someone else sick.

The more time you talk to an infected person, the higher your risk.
If you are in a poorly ventilated room with an infected person, who is speaking, you have a 20 percent risk of infection, the researchers found. The scientists concluded, “This analysis is caused by a mass fraction of liquid as a risk of continuous speaking in closed environments (for example, in a lecture hall), resulting in small droplets appearing.” For more regular COVID news, sign up for our daily newsletter.
Ventilation and multi-layer masks are important for staying safe.
The Cambridge team states that “infection … is extremely important in reducing the risk of infection indoors.” In a statement, D’Olivera said that the study shows “how these small droplets can accumulate in indoor locations over a long period, and how it can be reduced with adequate ventilation.”
The team used their findings to build an online calculator that can help users assess the risk of various indoor conditions, given the size of a room and the number of people in it. If you are spending an hour in an average-sized store with a capacity of 50 people, for example, improving ventilation or wearing a three-pail face mask can reduce the risk of infection from 8 percent to 2 percent.
“The idea is not to obtain absolute risk figures from the instrument, but to use it to see how the mitigation strategy affects the risk of infection,” de Oliveira explained Guardian. For more, where the outbreak of COVID is the worst yet, see how bad it is in your state.
