• Most coronavirus infections occur when someone stands within two meters of someone with COVID-19.
  • Indoor gatherings remain risky even when people are socially distant, as droplets linger longer in the air with poor ventilation.
  • Vaccination efforts in the US need to be stepped up to fight the spread of more contagious and resilient COVID strain from South Africa.

Much of what we know or thought we knew about the coronavirus has changed in the past few months. This is to be expected, of course, as health experts and researchers were initially baffled by how the coronavirus manifested itself in patients and how it spread so quickly.

Now that we’ve been in the pandemic for almost a year, health professionals have a much more accurate idea of ​​how the coronavirus is spreading and what, in turn, can be done to reduce the likelihood of transmission. Suffice it to say that while endlessly washing your countertops and sanitizing your home is important, it doesn’t go into how most people have likely come into contact with COVID-19.

according to to the CDCCOVID-19 spreads easiest when a COVID-19 positive person is in close proximity to another person. And since it is usually transmitted via breath droplets, frequent activities such as laughing, speaking, or even breathing heavily can increase the likelihood of transmission. In fact, heavy breathing is exactly why an activity like going to the gym can be particularly risky.

The following CDC describes how COVID-19 typically spreads between two people:

  • Individuals who are physically close (within 6 feet) of someone with COVID-19 or who have direct contact with that person are at the greatest risk of infection.
  • When people with COVID-19 cough, sneeze, sing, speak, or breathe, they produce droplets of breath. The size of these droplets can range from larger droplets (some of which are visible) to smaller droplets. Small droplets can also form particles if they dry very quickly in the air stream.
  • Infections mainly occur from exposure to respiratory droplets when a person is in close contact with someone who has COVID-19.
  • Respiratory droplets cause infections when they are inhaled or deposited on mucous membranes, e.g. B. those that line the inside of the nose and mouth.
  • As the respiratory droplets move further away from the person with COVID-19, the concentration of these droplets decreases. Larger droplets fall out of the air due to gravity. Smaller droplets and particles spread out in the air.

Incidentally, one of the reasons why a COVID-19 infection is more likely in winter is that droplets tend to linger longer in the air in colder and drier air environments.

The CDC adds that airborne transmission of COVID-19 poses a transmission risk even if people adhere to social distancing guidelines. While the CDC is rarer than direct person-to-person transmission, it writes that these transmissions usually take place in enclosed spaces with below average ventilation.

Under these circumstances, scientists believe that the amount of infectious smaller droplets and particles produced by people with COVID-19 has been concentrated in such a way that the virus can be transmitted to other people. The infected people were in the same room at the same time or shortly after the person with COVID-19 left.

Indeed, indoor gatherings are therefore particularly risky, even if people remain socially distant. The U.S. has recorded 26.4 million coronavirus infections and 446,643 COVID deaths to date.
