Influenza Cases from Surveillance Acute Respiratory Infection in Indonesia, 2011
Severe Acute Respiratory Infection (SARI) or pneumonia has a major contribution in the morbidity and mortality, however, Indonesia still has lack of its epidemiology. The aim of the study is to know the epidemiological pattern of influenza virus as the etiology of SARI cases.
This analysis based on the sentinel surveillanceSARI conducted by Center for Biomedical and Basic Technology of Health (CBBTH) of Indonesia carried out at nine hospitals in nine provinces in 2011. Every patient who met the criteria of SARI was included in this study. Serum, throat and nasal swabs were taken and examined at the Virology laboratory CBBTH to determine the etiology. RT-PCR was used to detect type and subtype of influenza viruses from swabs.
Total number of SARI cases were 333. We found 6% cases were influenza positive by RT-PCR. The proportion of influenza A was 5% and influenza B 1% from total SARI cases. We detected that seasonal influenza A subtype H1N1pdm09was the dominant subtypes that circulating in Indonesia. We foundseasonal Influenza infection from SARI patients, however, it was only small number. Therefore, further detection of SARI cases is needed.
