Worst mumps outbreak in 23 years

University of Auckland senior lecturer in vaccinology Helen Petousis-Harris tells Kathryn Ryan a mumps outbreak in Auckland could get worse. Our biggest city is facing its worst outbreak of the virus since 1994, with the Auckland Regional Public Health Service seeing 740 new cases of mumps this year. Medical officers say the virus was contained late last year, with 13 cases reported in 2016. Complications from having mumps can include meningitis or encephalitis, with young children most at risk.
