摘要

To the Editor: After the 2004 outbreak of highly pathogenic avian in. uenza (HPAI) in poultry in Lao People's Democratic Republic (PDR), the Ministry of Health implemented extensive virologic surveillance (1,2). Surveillance began in July 2005, and by early 2006, only sporadic cases were found. In July 2006, an outbreak of HPAI was confi rmed on 2 chicken farms in Vientiane, the capital city of Lao PDR (1,3). Most of Laos' ≈20 million chickens are kept on family-owned backyard farms; 3.2 million are on commercial farms (4). This production meets 80% of Lao poultry (chicken, duck, goose, quail) needs; imports from neighboring countries, either through legal trade or cross-border smuggling, account for the rest (3). Common poultry diseases occur frequently during the cold season, and lack of reportingof poultry deaths is of concern (4).Until February 2007, no human cases of in. uenza A (H5N1) had been reported in Lao PDR. To learn more about Laotians' knowledge of HPAI and perceptions of their risk, we con-ducted a cross-sectional survey.In March–April 2006, participants in 3 settings (Vientiane, urban; Oudo-mxay, semiurban; Attapeu Province and Hinheub District, both rural) were interviewed in the Lao language by means of a standardized 33-question survey. We recorded information about behavior, poultry handling and keeping practices, and poultry deaths. We used multivariate analysis (Stata, version 8; Stata Corporation, College Station, TX, USA) to analyze the factors associated with behavior changes

H5N1禽流感的病例。为了了解更多有关老挝人对高致病性禽流感的了解以及对他们的风险的认识,我们进行了一项横断面调查。2006年3月至4月,参加者参加了3种环境(万象,城市,奥多姆西,半城市,阿塔佩乌省和欣希布)通过标准的33个问题的调查,以老挝语访问了两个农村地区。我们记录了有关行为,家禽处理和饲养方法以及家禽死亡的信息。我们使用多元分析(Stata,版本8; Stata Corporation,美国德克萨斯州大学城)来分析与行为变化相关的因素
