However, this
link suggests that the total number of deaths in Hubei province (containing Wuhan) may have been ~10x higher than reported by the government based on the number of cremations performed by funeral homes in the area. For the first time since the outbreak, funeral homes have begun to release the cremated remains to family members in the last week and residents have estimated that 30,000-40,000 have been distributed.
The Chinese government reported 3,182 deaths in Hubei (from Johns Hopkins site). A 10-fold increase in deaths would suggest a much higher incidence of cases as well.
