After criticizing China for the delay in NPI, Benedict refused to recommend there use here while actively down playing the likelihood of the deadly results of the virus. I believe it was this study that was cited by Benedict Donald.
A study by the University of Southampton examining non-pharmaceutical interventions (NPIs) in response to the new coronavirus (COVID-19) in China shows that a range of early, coordinated and targeted measures are needed to help significantly reduce its spread.

"The research also found that if interventions in the country could have been conducted one week, two weeks, or three weeks earlier, cases could have been reduced by 66 percent, 86 percent and 95 percent respectively – significantly limiting the geographical spread of the disease. However, if NPIs were conducted one week, two weeks, or three weeks later than they were, the number of cases may have shown a 3-fold, 7-fold, or 18-fold increase, respectively."
