Shortly thereafter, several other cases emerged in the local area. To achieve early detection of H7N9 for timely diagnosis and treatment, the epidemiological and clinical information of all 6 cases were analyzed.Methods and Results: 2 cases were family members. 3 cases had a history of contacting with poultry. All of the 6 patients lived around two markets where H7N9 virus were found in chickens and pigeons. The main symptoms were fever, cough, and hemoptysis. At onset, a decreased lymphocyte counts and elevated creatine kinase (CK), LDH, and CRP levels were observed. As the disease progressed, most patients had dyspnea and hypoxemia. Imaging showed lung consolidation and multiple ground-glass opacities at the early stage, rapidly extending bilaterally. All patients were treated with oseltamivir tablets. The complication rates were as follows: ARDS(83.3%), secondary bacterial infection (66.7%), pleural effusion (50%), left ventricular failure (33.3%), neuropsychiatric symptoms (33.3%), and rhabdomyolysis (16.7%). 4 of 6 cases died of ARDS, only 2 cases were recovered.Conclusions: An outbreak of H7N9 infection was taken place in the Minhang District of Shanghai, which easily progressed to ARDS. Two cases showed family aggregation, which provided the key to discover H7N9 virus and indicated human transmission might exist.
