Abstract
Background: A series of social and public health measures have been implemented to contain coronavirus disease 2019 (COVID-19) in China. We examined the impact of non-pharmaceutical interventions against COVID-19 on mumps incidence as an agent to determine the potential reduction in other respiratory virus incidence.
Methods: We modelled mumps incidence per month in Sichuan using a seasonal autoregressive integrated moving average (ARIMA) model, based on the reported number of mumps cases per month from 2017 to 2020.
Results: The epidemic peak of mumps in 2020 is lower than in the preceding years. Whenever compared with the projected cases or the average from corresponding periods in the preceding years (2017-2019), the reported cases in 2020 markedly declined (P < 0.001). From January to December, the number of mumps cases was estimated to decrease by 36.3% (33.9-38.8%), 34.3% (31.1-37.8%), 68.9% (66.1-71.6%), 76.0% (73.9-77.9%), 67.0% (65.0-69.0%), 59.6% (57.6-61.6%), 61.1% (58.8-63.3%), 49.2% (46.4-52.1%), 24.4% (22.1-26.8%), 30.0% (27.5-32.6%), 42.1% (39.6-44.7%), 63.5% (61.2-65.8%), respectively. The total number of mumps cases in 2020 was estimated to decrease by 53.6% (52.9-54.3%).
Conclusion: Our study shows that non-pharmaceutical interventions against COVID-19 have had an effective impact on mumps incidence in Sichuan, China.
