To the extent that you can extrapolate out of studies from India:
1) 70% of people infected with COVID-19 don't infect anyone else.
2) 20% of people infected with COVID-19 infect one other person and are responsible for 40% of identified secondary cases.
3) The remaining 10% of people are responsible for 60% of identified secondary cases.
4) In India, at least, the "youts" (~ age 25 - 35) were responsible for most integenerational spread (figure 2C11). This is not a surprise, since they are caring for children and caring for their adult relatives.
