Abstract

 

Objective: This study was conducted to evaluate the pandemic (H1N1) influenza outbreak in 2009. Method: Influenza like illness (ILI) cases were reported between the 36^th to 53^rd weeks of the pandemic, from all health centres. 731 nasopharyngeal swabs were collected from ILI cases. Results: The first H1N1 confirmed case was reported at the 36^th week and an increasing trend continued. At the 43^rd week the outbreak reached its maximum level and at the 53^rd week the level had decreased to the level at the start. During the outbreak 31117 cases were reported as ILI and 635 cases were hospitalized (hospitalization rate was 2.0%) and 17 H1N1 laboratory confirmed cases died (mortality rate 11.5/1.000.000). Symptoms of laboratory confirmed cases were similar to seasonal influenza. Coughing (90.9%), fever (84.5%), running nose (69.5%), headache (73.4%), diarrhoea (17.5%) were the some of the symptoms in laboratory confirmed cases. The median interval between the onset of symptoms and hospital admission was 3.5 days (min: 1, max: 11 days) and this was 7.5 days for the occurrence of death. Conclusion: During 36^th to 53^rd week an important outbreak of ILI was occurred. The mortality rate was not so high as expected but the infectivity was high. The delay for hospital admission may lead to higher mortality particularly for pregnant women.

Diyarbakır’da pandemik (H1N1) influenza, 2009

Abstract

Amaç: Bu çalışmada 2009 yılında -Türkiye’de pandemik influenza salgınını değerlendirmek amaçlanmıştır. Yöntem: Diyarbakır ’da 36 ve 53. haftalar arasında tüm sağlık kuruluşlarından influenza benzeri hastalık rapor edilmiştir. 731 nazofaringeal sürüntü alınmıştır. Bulgular: İlk H1N1 doğrulanmış vaka 36.haftada rapor edilmiştir ve vaka sayıları zaman içinde artış göstermiştir. 43. haftada salgın başlamış ve 53. haftada başlangıç düzeyine inmiştir. Salgın sırasında 31117 vaka grip benzeri hastalık olarak raporlanmış, 635 vaka hastaneye yatmış (hastaneye yatış hızı %2.0) ve laboratuvar olarak doğrulanmış 17 vaka ölmüştür (ölüm hızı milyonda 11.5). Laboratuvar olarak doğrulanmış vakaların semptomları mevsimsel influenza ile benzerlik göstermiştir. Laboratuvar olarak doğrulanmış vakaların bazı semptomları öksürük (%90.9), ateş (%84.5), burun akıntısı (%69.5), baş ağrısı (%73.4) ve ishal (%17.5) olmuştur. Semptomların başlaması ile hastaneye başvuru suresi ortancası 3.5 gün (en az:1, en çok:11 gün), ölüm süresi ortancası ise 7.5 gündür. Sonuç: Diyarbakır’da 36 ve 53. haftalar arasında önemli bir grip benzeri hastalık salgını yaşanmıştır. Mortalite hızı beklenildiği kadar fazla olmamakla birlikte, bulaştırıcılık hızı yüksektir. Hastane başvurularındaki gecikme özellikle gebe kadınlarda ölüme yol açmış olabilir
