ObjectivesTo describe our experience in children hospitalized with the pandemic Influenza A (H1N1) from Northern India.MethodsThe retrospective case study was conducted at the Pediatric ward and Pediatric Intensive Care Unit (PICU) dedicated to the children (aged 18 years or younger) with influenza-like illness (ILI) with positive laboratory test results for pandemic H1N1 by reverse-transcriptase polymerase-chain-reaction assay.ResultsBetween August 2009 and January 2010, a total of 100 children were hospitalized with suspected 2009 H1N1 influenza with Category "C" as described by the Government of India. Twenty five patients were positive for H1N1 and 9 for seasonal influenza A. The most common presentation (H1N1 positive) was with fever (100%), cough (100%), coryza (52%), respiratory distress (88%), vomiting (28%) and diarrhea (16%). One child presented with hypernatremic dehydration and seizures (Serum sodium 174 meq/l). Of the H1N1 positive hospitalized children, 7 (28%) had respiratory failure and required PICU admission, 4 (16%) required mechanical ventilation, and 3 (12%) died. The major radiological findings were bilateral pulmonary infiltrates and consolidation. All patients were treated with oral Oseltamivir suspension or capsule as per appropriate weigh band and supportive care as required. Two deaths were caused by refractory hypoxemia and one by refractory shock.ConclusionsThe exact incidence of Pandemic 2009 H1N1 influenza on morbidity and mortality is difficult to calculate since only Category "C" patients were screened.
