claim: social distancing = > 80 % of the population, covid-19 may be curbed 13 weeks, < = 70 % may always be curbed.
evidence_1: we report an important transition across the levels of social distancing compliance, in the range between 70% and 80% levels.", "strong compliance with social distancing (at 80% and above) effectively controls the disease during the suppression period, while lower levels of compliance (at 70% or less) do not succeed for any duration of the suppression.", "this suggests that a compliance of below 70% is unlikely to succeed for any duration of social distancing, while a compliance at the 90% level is likely to control the disease within 13-14 weeks, when coupled with effective case isolation and international travel restrictions.", 
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  "the research found that if 90 percent of the australian population adopted social distancing, the spread of covid-19 could be controlled by july 2020, whereas social distancing of less than 70 percent would not suppress the pandemic.", "by mihai andrei april 7, 2020 in health & medicine, news, research, science strong social distancing measures can curb the pandemic in 13 weeks or so -- but only if 80% of the people do it, a new study claims.")
