  volt indiában egy covid-study, az lett az eredmény, hogy a fertőzések nagy részéért a superspeaderek felelősek, csomóan senkinek sem(!) adták át a fertőzést:

  The attack rate — or the risk of transmission from a primary case to someone else — was 80% for passengers sitting next to an infected person on a bus or train for more than 6 hours without a mask. By comparison, there was only a 9% chance of an infected person giving the virus to another member of their household. The chances of a person passing on the virus in a hospital or clinic was 1.2% and the attack rate was just 2.6% for interactions in the general community.
  In fact most people — 71%, according to this study — appear to have never passed the virus on to anyone. Given that the outbreak continues to grow, this means there are a small minority of patients responsible for the vast majority of spread.
  
  "We've never had a good handle on [superspreaders], and certainly no large-scale study," he says. "Here in this study, we found that 8% of the people who were infected were responsible for 60% of the infections that grew out of these primary cases."
