Both sheep and goat pox are contagious viral diseases and affect small ruminants and are caused by sheep pox virus and goat pox virus respectively that belong to genus Capripoxvirus of Poxviridae family. Huge economic losses emanating from the disease outbreaks are the results of the wool and hide damage, subsequent production losses and also the morbidities and mortalities associated with the disease. This communication highlights clinico-epidemiological observations from the two sheep pox and one goat pox outbreaks. Grossly, multisystemic nodular lesions, mucopurulent nasal discharges and respiratory symptoms were observed in the affected animals. The morbidity, mortality and case fatality rates were 5.18%, 2.45% and 32.37%, respectively. Histopathological, haematological, molecular and serological techniques and also isolation of virus in embryonated chicken eggs were used for the diagnosis of the diseases. The spatial distribution of the disease signifies the role of common pasturelands used for grazing the animals while temporally all three outbreaks occurred in winters and were probably associated with cold stress and fodder scarcity. This is the first recorded report of Capripoxvirus infection in recent times and it highlights the disease as one of the emerging diseases in the northern state of Himachal Pradesh in India.
绵羊痘和山羊痘都是传染性的病毒性疾病，影响小反刍动物，分别由绵羊痘病毒和山羊痘病毒引起，这两种病毒属于痘病毒科山羊痘病毒属。由于疾病爆发导致羊毛和皮损失、随后的生产损失以及与疾病相关的发病率和死亡率，造成了巨大的经济损失。本通讯重点介绍了两次绵羊痘和一次山羊痘爆发的临床流行病学观察结果。在受感染的动物中，肉眼可见多系统结节性病变、黏液脓性鼻分泌物和呼吸道症状。发病率、死亡率和病死率分别为 5.18%、2.45%和 32.37%。使用组织病理学、血液学、分子和血清学技术以及在鸡胚中分离病毒进行了疾病诊断。疾病的空间分布表明共同放牧的牧场在疾病传播中起作用，而时间上所有三种疾病均发生在冬季，可能与冷应激和饲料短缺有关。这是近年来首次记录到山羊痘病毒感染，它强调了这种疾病是印度喜马偕尔邦北部新兴疾病之一。
