<p class="abstract"><strong>Background:</strong> Mumps is an acute infectious disease caused by RNA virus. Clinically, the disease is presented as non suppurative enlargement and tenderness of one or both the parotid glands. The annual incidence of mumps in the absence of immunization is in the range of 100-1000 cases/100000 population. Mumps mostly occurs in children in age group of 5-9 years. The objectives of the study were to describe the epidemiological factors of cases admitted with

... d swelling; to describe the clinical features of patients admitted with parotid swelling; to assess the demographic factors in relation to complications.</p><p class="abstract"><strong>Methods:</strong> A cross sectional record based retrospective study was carried out at Sir Ronald Ross Institute of Tropical and Communicable Diseases, Hyderabad. All the cases admitted in year 2016 with unilateral or bilateral parotid swellings were included in the study. The study was carried out for 2 months. </p><p class="abstract"><strong>Results:</strong> The mean age of study population in present study was found to be 11.23 years. Around 35.9% of cases were found in the age group of 6-10 years. Males constituted 53.9% of study population and females were 46.1%. The mean duration between the onset of symptoms and admission in hospital was found to be 3.5 days. The most common clinical presentation was fever, parotid swelling and earache.</p><p class="abstract"><strong>Conclusions:</strong> Control of Mumps is difficult as the disease is highly infectious. Long and variable incubation period along with subclinical cases makes the control difficult. However, routine MMR vaccination as part of national immunization schedule can help in be preventing the epidemics.</p><p class="abstract"> </p>
