Methods The data of mumps in Hefei City from 2011 to 2016 was analyzed by descriptive epidemiology. Results There were a total of 9 678 cases of mumps in Hefei City from 2011 to 2016. The average annual incidence was 22.7/100 000, with the highest in 2013 being 40.56/100 000. Mumps had obvious seasonality with high incidence in spring. Mumps cases increased in winter but the peak was not distinct. The group with the largest number of cases was mainly students, accounting for 64.5% of the total number of cases, followed by childcare and residentially-scattered children. The average annual morbidity of nine counties existed differences( 2=256.845，P<0.001). Conclusions There was a high incidence of mumps in Hefei City from 2011 to 2016.
