The study evaluated the incidence of norovirus associated gastroenteritis in India. During the year 2005
to 2006, stool samples from communicable disease hospital were collected from subjects suspected for
non – bacterial gastroenteritis and were examined for norovirus. Samples were analyzed by reverse
transcriptase polymerase chain reaction and further confirmed by hybridisation and sequencing. In
addition the epidemiology of norovirus was studied by statistical analysis. 44.4% of the samples were
positive for norovirus, the isolated strain represented the Genogroup I of norovirus. The study
observed that norovirus infection is not only a winter vomiting disease it can also occur in the summer.
