AB Introduction: The epidemiology of novel H1N1 Influenza virus infection in tropical countries is not well described. To characterize the epidemiology of nH1N1 in Indonesia, we implemented enhanced surveillance for hospitalized patients with severe acute respiratory infection (SARI) in 12 Hospitals Tangerang, Indonesia in June 2009.Methods: We identified all hospitals that manage patients with respiratory illness and trained clinicians to identify SARI patients, collect clinical specimens and complete a standardized case investigation form. Throat and nasal swabs were tested by RT-PCR using primers from the US CDC.Results: Between June 28 and September 3, 2009, we identified 216 patients with SARI including 19 patients (9%) with nH1N1 infection. Patient with nH1N1 infection were identified in 7 hospitals and ranged in age from 11 months to 54 years (median age 20 years); 59% were male. The age specific rate for hospitalization 5.7 per 100,000 population. The number of patients with nH1N1 infection peaked in mid July which is the low season for seasonal influenza transmission in Tangerang, Indonesia. The median time from symptom onset to hospital admission was 2 days, ranging from 1 to 8 days. Six nH1N1 patients had complicated course of illness including 2 patients who died. Among the 19 nH1N1, 6 had underlying medical conditions. All patients with nH1N1 infection were treated with Oseltamivir.Conclusion: We observed a rapid rise in the number of SARI patients with nH1N1 infection shortly after introduction of this virus in Indonesia. The age distribution, clinical features, and mortality of hospitalized patients is similar to that observed in other countries.
