Corona Research: This is the number of people who infect super speakers on average


There are circumstances that favor a Covid-19 infection, such as contact with a super spreader.

Scientists were able to show that super diffusers contribute significantly to the spread of Covid-19 by triggering a chain reaction, often unconsciously.

  • Most Covid-19 infections occur in private households. But the virus carrier can usually be found outside your four walls.
  • So-called super-diffusion events promote the continuation of the pandemic. It can be a birthday party or a choir rehearsal – an infected person can infect many people with Covid-19 during the meeting. The tricky thing: People can even pass on coronaviruses if they don’t show any symptoms.
  • A small number of people can therefore be responsible for many infections. US researchers have now found out: this is how many people on average get infected with Covid-19 from super speakers.

The most common route of transmission of coronaviruses is droplet infection – infected people breathe or cough with contaminated respiratory droplets, which spread rapidly, especially indoors. However, there are still many questions about Corona that have not yet been definitively clarified: for example, where most people get infected with the virus. In a current assessment, the researchers conclude that the following three factors are the main drivers of the pandemic *:

  • Contagion in one’s family
  • tourist and professional trips
  • Contact with super speakers

The latter is likely to play a key role, as US researchers have found. In one study, they scientifically documented 60 Superspreader events evaluated and they have been able to track how many people have been infected with Covid-19 through them. The researchers defined the events in which one person infected more than six people with Covid-19 as a superspreader event.

Super speakers infect an average of 20 people – small group meetings as a solution?

In the case of the 60 events examined, between ten and 55 people were infected by one person: for example, six at a family reunion in Singapore and 187 in an apartment building in Hong Kong. On average, one person infected with the virus infected 20 other people, as Felix Wong and James Collins of the Massachusetts Institute of Technology (MIT) found in their study. The researchers also concluded: Limiting meetings to ten or fewer people can significantly reduce super-outbreak events and also the overall number of infections, as cited by Business Insider.
