Bioecological factors & rotavirus diarrhoea. Indian Journal of Medical Research. 1990 May; 91(): 167-70http://imsear.searo.who.int/handle/123456789/24013Rotavirus was detected (using Rotalex) in 11.72 per cent (120 of 1024) children below 3 yr age with diarrhoea. None of the 25 healthy control children excreted rotavirus in their faeces. Group specific ELISA for 89 Rotalex positive samples revealed 30 subgroup I and 43 subgroup II whereas 10 were untypable. Rotavirus infection ranged from 2.8 to 22.20 per cent in different months. There was no correlation with mean minimum and maximum temperatures. However, the incidence showed a negative correlation (r = -0.645) with relative humidity. Children between the age of 10 to 12 months had the maximum incidence of rotavirus infection. Male patients were found to be more susceptible to infection than females (3.3:1).engChild, PreschoolDiarrhea --epidemiologyDiarrhea, Infantile --epidemiologyFemaleHumansHumidityIncidenceIndia --epidemiologyInfantMaleRotavirus --classificationRotavirus Infections --epidemiologySeasonsJournal Article
