Genotyping and subtyping of mumps virus isolates from the Indian subcontinent

Abstract

Mumps is a vaccine-preventable disease that usually occurs as a self-limiting parotitis, but it can also lead to several life-threatening complications, including pancreatitis, meningitis, and encephalitis. The molecular epidemiology of the virus is poorly understood. The present study describes an outbreak of mumps virus infection in Punjab, India. The etiology was confirmed by serology and RNA detection to be mumps virus in 72 % of the cases and 50 % of contacts. This study, for the first time, revealed the mumps virus genotypes circulating in the Indian subcontinent as subtype G2 of genotype G.
