Mumps Epidemiology and Mumps Virus Genotypes Circulating in Mainland China during 2013-2015
Fig 4
A Bayesian skyline plot analysis of the representative Chinese genotype F MuV sequences from 1995–2015.
Ordinate: the number of effective infections at time; abscissa: time (in years). The thick solid line represents the median, and the blue area represents the 95% highest probability density (HPD) of the number of effective infections at the time estimates. The number of mumps cases according to the NNDRS is shown for each year below the skyline plot. *the data of the epidemiology surveillance of mumps during 1995–2003 were unavailable.
