We have conducted rotavirus studies over different periods in five sites to see the burden of diarrhoea cases. There is also literature on the basis of which we have calculated that almost one lakh children die due to rotavirus every year. Chances of severe diarrhoea and death are high in early infections of rotavirus, but subsequent episodes are known to be less severe. By the time the child is a year old, we may not be able to diagnose the virus since the infection will be less severe, not conspicuous. For Hib too, we need to have proper facilities to diagnose the problem, along with samples to do culture and sensitivity tests for finding out the disease burden. There is no standard protocol to diagnose and treat pneumonia. In smaller areas, children are mostly given antibiotics without diagnosing if the pneumonia is due to Hib.
