Background: Mumps is a contagious viral infection that primarily affects children and young adults. The disease is characterized by swelling of the salivary glands, which causes pain and fever. Although the incidence of mumps has decreased in recent years due to vaccination, outbreaks continue to occur. Mumps can lead to serious complications, such as meningitis, encephalitis, and pancreatitis, particularly in unvaccinated individuals. Aim of the study: The aim of the study was to understand the epidemiology, clinical features, and management of mumps in children is crucial for preventing and managing outbreaks. Methods: This hospital-based prospective observational study was conducted at the Department of Pediatric High Dependency and isolation, Bangladesh Shishu Hospital & Institute, Dhaka, Bangladesh. This study enrolled and analyzed sixty patients from January 2019 to December 2021. Result: The majority of patients, 56.67%, were between 6-10 years old, 23.33% were between 1-5 years old, 13.33% were between 11-15 years old, and 6.67% were between 16-18 years old. The mean duration of illness was 9.0±2 days. Furthermore, 60% of patients experienced constitutional symptoms such as headache, myalgia, or fatigue. Cough and dysphagia were observed in 83.33% and 47% of the patients, respectively. Conclusion: In conclusion, preventing mumps in children is crucial to reducing the disease burden in Bangladesh. Vaccination is the most effective way to prevent mumps, and the vaccine is available in the country's national immunization program. However, vaccine coverage must be improved to ensure that all children receive the vaccine.
