This study was done to detect the causative agent of patient with respiratory disease in Pusan, 1997. Male and female patients with respiratory disease in Pusan, 1997, were 31.9% and 68.1 ％, respectively. In the aspect of out-break by month, patients with respiratory disease were mostly concentrated at February, March, April, October, November and December. Fifteen strains of influenza virus were isolated from 1,268 swabbed samples of throat, and thirteen strains and 2 strains among 15 isolates were classified with influenza A and B virus, respectively. One of 13 influenza A virus was confirmed as A/Johannesburg/33/94- like strain, and the other isolates of influenza A virus were confirmed as A/sydney/05/97-like strains. Two isolates of influenza B virus were confirmed as B/Bei-jing/08/93-like strains.

Avian influenza viruses infect humans, horses, swine, other mammals, and a wide variety of domesticated and wild birds. Modem poultry industries worldwide are at risk of infection with avian influenza. Low pathogenic avian influenza can easily change to highly pathogenic form especially when introduced into areas of high density commercial poultry. Outbreaks of highly pathogenic avian influenza are becoming progressively more expensive to control according to the growth of the poultry industry worldwide. Future strategies for avian influenza control and prevention should involve a combination of early detection and characterization of virus using advanced molecular biologic techniques, quarantine, selective depopulation and vaccination of flocks.

Influenza is a common disease that causes epidemics yearly due to the influenza virus. If patients with influenza present with rare symptoms, the diagnosis may be delayed and the condition is difficult to treat. A 5-year-old boy presented to the emergency room with fever and cramps. Brain computed tomography showed low attenuation in the thalamus and brain stem, which was suggestive of encephalopathy caused by influenza virus. Another 5-year-old girl visited the emergency room with mild fever and painful calf edema. She was diagnosed with myositis caused by influenza and treated accordingly.

Avian influenza viruses playa crucial role i,n the creation of human pandemic viruses. In this study, we have demonstrated that both human and avian influenza receptors exist in cells in the respiratory and intestinal tracts of chickens. We have also determined that primarily cultured chicken lung cells can support the replication of both avian and human influenza viruses.

목 적 : 소아청소년을 대상으로 2010-2011 인플루엔자 백신의 야외 효능을 확인하고자 하였다. 방 법 : 2010년 9월에서 2011년 2월까지 소아 청소년을 대상으로 서울 경기지역의 7개 병원과 1개 초등학교에서 인플루엔자 백신을 접종한 시험군과 접종하지 않은 대조군을 모집하였다. 급성 발열성 호흡기 질환 증상이 있을시 임상시험기관에 방문하도록 하여 검체를 채취하여 감염여부를 확인하였다. 결 과 : 시험 군 407명 중 3명(0.74%)에서 3건의 신종 H1N1 인플루엔자 바이러스가 검출되었고, 대조군 230명 중 10명(4.35%)에서 12건을 검출하여 9명(3.91%)에서 9건의 신종 H1N1, 3명(1.30%)에서 3건의 H3N2 인플루엔자 바이러스를 검출하였다. 시험군에서의 인플루엔자 발생률은 0.74%, 대조군에서 4.35%였다. 백신의 야외 효능은 83.2%였다. 결 론 : 소아청소년을 대상으로 2010-2011년 인플루엔자 백신의 야외효능은 우수하였음을 확인하였다.

Objective : Lonicerae Flos has detoxifying properties and been used as antipyretic, antibacterial and antitumor. Fermentation of herbal medicine is known to increase the absorption, enhance effectiveness, decrease herbal toxicity and reduce side-effects. This study was performed to measure the effects of fermented Lonicerae Flos on influenza A/WSN (H1N1) virus replication. Material and Methods : Lonicerae Flos was fermented by Lactobacillus casei PM1. Fermented Lonicerae Flos was treated for 12 hours to MDCK (Mardin Darby canine kidney) cells, then cell-virulence was observed by MTT assay for 12 hours, 24 hours, and 36 hours after treatment. Following cases were conducted for 0, 10, 100, and $1000{\mu}g/ml$ concentrations of fermented Lonicerae Flos under the same time-frame; the fermented Lonicerae Flos was treated to MDCK cells before and after contamination by A-type influenza virus. The fermented Lonicerae Flos and the virus were mixed directly. The influence was observed by MTT assay and plaque assay. Results : These findings suggest that the fermented Lonicerae Flos inhibited the virulence of influenza A virus in MDCK cells and suppressed the plaque forming colonies induced by influenza A virus. Furthermore, pretreatment with fermented Lonicerae Flos was more effective than post-treatment. The titer of influenza virus was reduced for all before and after influenza A virus inoculation.

Purpose: The purpose of this study was to examine womens' perceptions regarding influenza vaccination during pregnancy among Korean childbearing women. Methods: Data was collected using focus group interviews from June to September, 2010. Forty Korean women participated in 13 focus groups. After obtaining permission from participants, each session of the focus group was audio-taped and transcribed verbatim. The responses were analyzed utilizing qualitative content analysis. Results: Forty women ranging from 26 to 43 participated in the study. The major themes were safety concerns; effects of fetal protection and infection prevention; lack of perceived needs; and encouragement as well as concerns from others. Participants raised questions on whether the vaccine was safe and effective, and concerns about the potential harmful effect of influenza vaccine to their bodies and the fetus. The major reason for influenza vaccination during pregnancy was to protect self and fetus. Also, clinician's recommendation was the facilitating factors for influenza vaccination during pregnancy. Conclusion: The findings suggest that concerns associated with influenza vaccination should be considered when educating childbearing women about the influenza vaccine during pregnancy.

Influenza virus is a major cause of respiratory infection in the epidemic season. Especially, the elderly with underlying health problems are at increased risk for complications of influenza. The objective of this study was to investigate that influenza vaccination can reduce the hospital admission rate related to the respiratory diseases. This study was a retrospective study of two age groups, who are the healthy children aged 6 months to 9 years (n=237) and the adults aged over 20 years with respiratory disease (n=327). The vaccinated groups were compared to the controls that were matched in sex and age. The children were vaccinated in winter season of 1995-96 and the adults were vaccinated in 1996-97. The efficacy of influenza vaccine was evaluated with the number of outpatient visits in children group, the admission rate and the mean admission days in both children and adult group. As results, there were not significant differences between the vaccinated and the control group of children. In the elderly over 61 years, however, the influenza vaccination can reduce the admission rate $(8.9\%\;vs.\;25.6\%,\;p<0.05)$ and the mean admission days (1.3 vs. 3.8 days, p<0.05) compared to the control. In conclusion, influenza vaccination can effectively reduce the events related to respiratory infection in the elderly than the children. The elderly should be recommended for influenza vaccination.
