Fig 1.
The mumps cases in mainland China by year (A) and by month (B) from 2004–2015.
Fig 2.
The age distribution of mumps cases in China from 2004–2015.
Table 1.
The values of the P distance among genotype F mumps virus strains and the Jeryl Lynn strain (MuCV strain) in China.
Fig 3.
The phylogenetic analysis of the 39 representative Chinese genotype F MuV sequences from 2013–2015.
The tree was drawn based on the SH sequence. The eight genotype F MuV sequences from other countries are indicated with solid blue triangles. The WHO reference virus sequences and the three mumps virus unclassified strains for genotyping obtained from GenBank are indicated with solid red dots.
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.
Fig 5.
The phylogenetic analysis of the Chinese genotype G MuV sequences.
The tree was drawn based on the SH sequence. The 11 Chinese genotype G mumps virus strains are indicated with solid blue triangles, and the WHO reference virus sequences and the three mumps virus unclassified strains for genotyping obtained from GenBank are indicated with solid red dots. The representative mumps virus strains collected from other countries deposited in GenBank are indicated with solid pink diamonds.
