Where and how are you most likely to get COVID-19? This is what a new study says – Tech Viral Tips

Two years later global pandemicMost of us are fed up. case rate COVID-19 They are higher than ever, and hospitalization rates are again rising rapidly in many countries.

Faced with this bleak outlook, we yearn for a return to normalcy. We want to meet friends at the bar or invite them to dinner. We want our struggling business to flourish as it did before the pandemic. We want our children to return to their familiar routine of face-to-face learning and after-school activities. We want to travel by truck, sing in the choir, go back to the gym or dance in a club without the fear of catching COVID.

Which of these activities is safe? And how safe is it really? These were the questions we wanted to answer in our final Research.

SARS-CoV-2The virus that causes COVID is mainly spread by air transmission, So the key to stopping transmission is understanding how airborne particles behave, which requires knowledge of physics and chemistry.

Air is a fluid composed of invisible molecules that move rapidly and randomly, so the particles expand over time. closed spaces, such as in a room or on a bus. An infected person can inhale virus-containing particles, and the closer you are to them, the more likely they are to get inside. But the longer you both spend in the room, the more the virus will spread. if you fresh air, space is almost infinite, so viruses do not accumulate in the same way. However, the virus can still spread if someone is around.

Viral particles may be emitted every time an infected person breathes, but especially if their breathing is deep (such as while exercising) or vocalizations (such as speaking or singing) are involved. when using a face mask Tight fitting reduces transmission by blocking the release of the virus, making it much less likely to become infected by sitting quietly in a corner without the infected person, if a heated discussion is approached and initiated.

All forms of SARS-CoV-2 are equally transmitted through the air, but the chances of contracting COVID depend on Ability (or infectivity) of type (delta was more contagious than previous variants, but omicron is even more contagious) and how many people are currently infected (disease prevalence). At the time of writing, over 97 per cent of COVID infections in the UK are caused by Omicrons and one in 15 people are currently infected (prevalence 6.7 per cent). While Omicron appears to be more transmitted, it also appears to cause less severe disease, particularly among those who have been vaccinated.

likely to be infected

In our study, we determined how different effects on transmission alter the risk of getting sick: viral factors (infection/dissemination), people factors (with/without mask, exercise/sitting, talking/silent) and quality of life. Factor. Air (indoor / outdoor, large / small room, full / thin space, ventilated / unventilated).

We did this by carefully studying empirical data on how many people were infected in superpropagation events, where key parameters such as room size, occupancy and ventilation level were well documented, and showing how transmission occurs with mathematical models. Is.

The new table, adapted from our article and shown below, provides the percentage chances of getting infected in a variety of situations:


The perfect ‘recipe’ for contracting COVID

One sure way to get COVID is to do a combination of things that get you to the dark red cells of the table. for example:

  • Meeting many people with poor air quality in a confined space, such as a gym, a den, or a poorly ventilated classroom.
  • Getting tired or doing something noisy, such as exercising, singing or shouting.
  • Do not use mask.
  • stay there for a long time.

how to avoid getting it

To avoid COVID, you can try to stay in green or amber spaces of the table. for example:

  • If you must gather with other people, do so outside or in a well-ventilated area.
  • Set the maximum number of people.
  • Spend as little time as possible with them.
  • Don’t shout, sing, or take a deep breath.
  • Wear high quality, well fitting masks.

While the graph provides an estimate for each situation, the actual risk will depend on specific parameters, such as how many people are actually in a room and how big it is.
