본 연구는 질병역학의 관점에서 2014년 발생한 HPAI(H5N8)의 시간적 분포와 공간적 분포 그리고 시·공간을 동시에 고려한 분포를 지리정보시스템과 연계하여 분석함으로써 2014년 발생한 HPAI의 전파 및 확산 특징을 알아보고자 한다. 분석 결과 2014년 HPAI는 시간적으로는 모두 3번의 파동을 형성하였으며, 공간적으로는 경기도·충청북도·충청남도가 인접하는 지역, 전라북도의 곰소만 일대, 전라남도의 영암과 나주 등 영산강과 인접한 지역에서 높은 밀도를 보였다. 시·공간적으로도 공간 밀도가 높은 충청북도 음성지역, 전라북도 부안·고창지역, 나주지역에서 군집이 형성되었다. 다만, 충청북도 음성·진천, 충청남도 천안, 경기도 안성·이천 지역과 전라남도 영암 지역에서는 공간적인 밀도는 높음에도 불구하고 시간적인 범위가 넓음으로써 시·공간 군집이 형성되지 못하였다. 이는 이들 지역의 방역에 문제가 있음을 의미한다. 반면에 곰소만과 인접하고 있는 전라북도 부안·고창·장수 지역은 시·공간 군집이 형성됨으로써, 상대적으로 효과적인 방역이 수행되었다고 볼 수 있다. Outbreaks of highly pathogenic avian influenza(HPAI) subtype H5N8 have occurred in Korea, January 2014 and it continued more than a year until 2015. And more than 5 million heads of poultry hads been damaged in 196 farms until May 2014. So, we studied the spatial, temporal and spatio-temporal patterns of the HPAI epidemics for understanding the propagation and diffusion characteristics of the 2014 HPAI. The results are expressed using GIS. Throughout the study period three epidemic waves occurred over the time. And outbreaks made three clusters in space. First spatial cluster is adjacent areas of province of Chungcheongbuk-do, Chungcheongnam-do and Gyeonggi-do. Second is Jeonlabuk-do Gomso Bay area. And the last is Naju and Yeongam in Jeollanam-do. Also, most of spatio-temporal clusters were formed in spatially high clustered areas. Especially, in Gomso Bay area space density and spatio-temporal density were concurrent. It means that the effective prevention activity for HPAI was carried out. But there are some exceptional areas such as Chungcheongbuk-do, Chungcheongnam-do, Gyeonggi-do adjacent area. In these areas the outbreak density was high in space but the spatio-temporal cluster was not formed. It means that the HPAI virus was continuing inflow over a long period.

Pathological findings of leucocytozoonosis naturally occurred in Korea are described. Most of the affected chickens showed paleness of comb and wattle, egg drop, approximately 20 to 30% mortality, green diarrhea, anorexia and weakness. On the blood smear merozoits and gametocytes were detected. At necropsy, petechial and ecchymotic hemorrhages in liver, kidney, heart, muscle, and splenomegaly were frequently observed. Microscopically schizonts with fine granular merozoits were often detected in kidney, intestine, brain, lung, myocardium, muscle, liver with cenrilobular fatty change, and spleen.

In the present study, the outbreak patterns of bovinebrucellosis in Korea from 2000 to 2011 were analyzed tounderstand the epidemiological evolution of this disease inthe country. A total of 85,521 brucella reactor animals wereidentified during 14,215 outbreaks over the 12-year studyperiod. The number of bovine brucellosis cases increasedafter 2003 and peaked in 2006 before decreasing thereafter. The majority of the bovine brucellosis cases were Koreannative cattle, Han Woo. The numbers of human brucellosiscases and cattle outbreaks increased and decreased in thesame pattern. The correlation coefficient for human andbovine cases per year was 0.96 (95% confidence interval =0.86∼0.99; p < 10−3). The epidemiological characteristicsof bovine brucellosis appeared to be affected by the intensityof eradication programs that mainly involved a testand-slaughter policy. Findings from the present study werebased on freely available statistics from web pagesmaintained by government agencies. This unlimited accessto information demonstrates the usefulness of government statistics for continually monitoring the health of animal populations.
Original Articles : Description of national avian influenza surveillance program in Korea

This study describes the national program of year-round surveillance and monitoring for avian influenza (AI). The validity of the epidemiologically-based surveillance scheme was assessed. Korea’s current surveillance program is aimed at detecting subclinical infection of either the highly pathogenic avian influenza (HPAI) virus or the low pathogenic avian influenza virus, types H5 and H7, both of which carry risk of converting to HPAI. The current AI surveillance program has demonstrated that implementing a surveillance strategy is plausible. Farmer and livestock related professional support is the critical step of specimen collection to discover hidden infection. Early detection of AI virus infection can achieve best by the combined efforts of farmers, animal health authorities, and other related industries.
