Outline of Final Research Achievements

We compared school closures during seasonal influenza and H1N1 influenza in the timing of closure (percentage of absentee per school) and days of closure.In seasonal influenza, average timing was 12.8% of absentee at school and closure was average of 4.2 days and in H1N1 influenza, average timing was 5.7% and average of 4.2 days. The peak and reported number of the outbreak (10% of absentee per school) was larger in seasonal influenza than H1N1. Small outbreaks (reported number of 5%) were more in H1N1 than seasonal influenza. Proactive school closures might decrease the peak of the outbreak but might not decrease total patient number. Students number per school, population density of the school area, days of the week (Monday) were factors that brings early outbreak. Too much school closures said to decrease the economy thus proactive school closures might not be needed in seasonal influenza seasons.
