Abstract
This study is based on clinical information on 894 subjects diagnosed with influenza (H1N1) 2009 in Nara Prefecture from June 15, 2009, to March 4, 2010, and from July 9, 2010, to March 6, 2011. Clinical data for 2009-2010 and 2010-2011 was compared. Results showed that 43% of 2009-2010 subjects were 0-9 years old and 38% were 10-19 years old. They also showed that 25% of 2010-2011 0-9 years old, 20% 10-19 years old, 20% 20-29 years old and 16% 30-39 years old. Both seasons showed a high percentage of subjects 0-9 years old. Numbers of subjects aged 20-39 years old increased in 2010-2011. Results thus suggest that an age shift occurred in subjects, in Nara Prefecture. The most frequent symptom was fever, e.g., 38 degrees C, in 88%. Upper airway inflammation was seen in 68%, lower airway inflammation in 20% and gastroenteritis in 6%. Lower airway inflammation decreased from 20% in 2009-2010 to 7% in 2010-2011. Neuraminidase inhibitor was prescribed for 408 (46%) subjects, oseltamivir for 262 (63%), zanamivir for 120 (29%), peramivir for 10 (2.4%), and laninamivir for 12 (2.9%). Two neuraminidase inhibitors were prescribed for 11 subjects. Oseltamivir prescription rates were lower among subjects 10-19 years old, following guidelines for the use of antiinfluenza drugs.
