Dr. Ben Cowling, an epidemiologist at the University of Hong Kong who researches influenza transmission and control measures, told Business Insider that case counts and death tolls are "often misleading," but he added that scientists know how to work around that.
"Most countries have not relied on data from China to make their policies," Cowling said in an email, referring to concerns about the data's accuracy. "A number of expert scientists used information on infections in Chinese travelers as a more accurate way to measure the occurrence of infections in China... because travelers were being monitored very carefully in some countries."
