Abstract :

In last few years, novel influenza A (H1N1) cases have created a lot of panic and concern in health and public sector. There are very few studies in the literature depicting its epidemiological profile in context to indian sub continent. A retrospective descriptive study was performed in 277 H1N1 positive category C cases from August 2012 to August 2015 admitted in HINI isolation wards of G. G. Hospital. From the analysis of data it was found that the disease morbidity was maximum in middle age group (12 to 40 years), while the older ones had more mortality. Females had more mortality and the disease trend was found very grave in antenatal cases and cases having multiple co morbidities. Longer the lag period between the onset of first symptom to admission in isolation ward, worse was the outcome. More than half of the cases required ventilatory support in the form of invasive or non invasive ventilation.
