INTRODUCTION : Mumps is an acute viral illness caused by a paramyxovirus called the mumps virus. Virus is acquired by
respiratory droplet transmission. It replicates in the nasopharynx and regional lymph nodes. Incubation period of mumps
is usually 16 to 18 days. Variety of causes have been attributed to the recent spike in mumps cases in India, including
changing climatic patterns, elevated pollution levels, inadequate preventive measures and weakened immunity. Our study
intends to investigate the burden of mumps cases in the last three years and their trend.
METHODS : Mumps cases reported from April 2021 to March 2024, in IHIP-IDSP portal for Tamil Nadu has been collected
from the IDSP-IHIP portal and exported to Microsoft Excel. Statistical analysis was done using SPSS 21.0.
RESULTS : Study reported 8±3.14 years as the average age of the mumps cases. Of the reported cases 56.05% of the cases were
female, while 43.87% were male. 31% percent of the cases were reported from Chennai. The incidence per lakh population
has increased significantly from 0.07 in 2021 to 1.3 in 2024.
CONCLUSION : We conclude that the number of mumps cases has been steadily increasing over the years, with a significant
surge in 2024 to suggest that mumps can be included as a notifiable disease in Tamil Nadu to improve surveillance and
control measures.
