A spokeswoman for the U.S. Centers for Disease Control and Prevention (CDC) acknowledged "We know that [the stated death toll] is an underestimation", a statement corroborated by anecdotal reports of undercounting in the U.S. Such underestimation often occurs in pandemics, such as the 2009 H1N1 swine flu epidemic.The first confirmed death was in Wuhan on 9 January 2020.
