An outbreak of mumps meningoencephalitis in Sangli district.

The epidemiology of mumps in India and the magnitude of the problem are not fully appreciated(2). Outbreaks occur at interval of 5-10yrs(2). Mumps continue to occur in epidemic proportions despite the availability of an effective vaccine. Finland became the first documented country to be free of indigenous mumps and rubella with the use of national 2 dose trivalent MMR vaccination program, free of charge and on a voluntary basis, which was launched in 1982(3). We are reporting this case study because, though 9 out of 10 of our patients were vaccinated with MMR vaccine they developed serious complication of mumps like meningoencephalitis.
