Emerg Infect Dis. 2010 Nov;16(11):1786-8. doi: 10.3201/eid1611.100323.

Abstract

During 2009, a total of 10,844 laboratory-confirmed cases of pandemic (H1N1) 2009 were reported in Beijing, People's Republic of China. However, because most cases were not confirmed through laboratory testing, the true number is unknown. Using a multiplier model, we estimated that ≈1.46-2.30 million pandemic (H1N1) 2009 infections occurred.
