摘　　要：为了解蓝田县汤峪镇猪疑似高致病性蓝耳病的流行特点、传播途径及发病特点,选取某镇十个村庄的养猪户(场)调查发现,该镇猪疑似高致病性蓝耳病的传播流行以每年高温、高湿时期多发;以直接或者间接接触为主要传播途径,并且以散养、中小规模饲养户、饲养管理粗放的户(场)发病为主;该病可发生于不同年龄、品种、性别的生猪,但以仔猪的发病率、死亡率最高;发病后以抗生素和中成药治疗为主,但其效果欠佳。防制应以紧急免疫、隔离和无害化处理病死猪为主要措施。Ten household or intensive pig farms were investigated in Tangyu Town, Lantian County, Shaanxi Province, to characterize the epidemiology of symptoms similar to that of the highly pathogenic porcine reproductive and respiratory syndrome （HP-PRRS）. We observed that HP-PRRS-like symptoms occur majorly in the high temperature, high humidity seasons of the year in the household and small-medium scale farms, or farms with an extensive management system. Although all pig strains suffered from HP-PRRS in both sexes at various ages, the highest incidence and mortality rate is in piglets. The disease spreads directly or indirectly. We noted that antibiotics and Chinese medicine are the most common used medicines to treat this disease but are found to be less effective. We suggest that emergence vaccination and isolation of the infected individuals and innocuous treatment of the dead bodies should be employed to stop this disease.
