Epidemiology of Pandemic H1N1 in Oman and Public Health Response, 2009 | OMICS International

A retrospective study of influenza-like illness (ILI) in Oman was completed to describe the epidemiology of pandemic influenza A, subtype H1N1 activity (pH1N1). From June to December 2009, 8,941 specimens were collected nationwide from patients that met the case definition for ILI, of which 6,547 (73%) were tested for pH1N1 by real-time polymerase chain reaction (RT-PCR). Out of these, 4,089 (62%) were found positive for pH1N1 and 712 (11%) were positive for seasonal influenza A. The mean age of patients positive for pH1N1 was 24 years (28 days-74 years). Out of the total patients who met the definition of severe acute respiratory illness (SARI) and required hospitalization, 28.3% were positive for pH1N1. The overall case fatality rate was 1.1 deaths/100,000 populations. Two governorates, Muscat and Dhofar, witnessed the greatest intensity of influenza activity. Mitigation, containment, pharmaceutical and non-pharmaceutical measures were engaged. Based on the experience and lessons learned in Oman, some recommendations were sought in Oman
