    未经批准:两种地方性水痘传染病,羊痘(SP)和山痘(GP)在亚洲很常见,非洲,和中东。绵羊和山羊,总的来说,被认为是小农户和边缘农户的流动资产,在肉类方面具有显著的经济价值,羊毛,和皮肤/皮革生产。印度的绵羊和山羊种群总数为14888万和7426万,分别。Capripox仅在马哈拉施特拉邦(印度)就造成了230万美元(印度卢比[INR]1.05亿美元)的经济损失,一群人花了6年的时间才从疫情中恢复过来。国家一级的预计年度损失为2747万美元(1250万卢比)。因此,羊痘疾病使小型和边缘农民承受着巨大的财务压力。本研究使用系统评价和荟萃分析估计了亚洲和非洲大陆SP和GP疾病的血清阳性率。研究结果将有助于研究人员和决策者了解疾病的时空分布及其负担。此外,研究结果也有助于设计和实施针对这些疾病的特定地点预防和根除措施。
    UNASSIGNED:使用Cochran合作的系统评价和荟萃分析指南的首选报告项目进行系统评价,随后使用荟萃分析。文献是从各种数据库中收集的。初始搜索字符串使用关键字和布尔运算符(或不)星号*和引号的不同组合,在2000年至2020年期间产生了超过9000篇文章。在9398篇论文中,选择了80项研究,使用纳入和排除标准进行完整的测试综述和质量偏倚评估。最后,21篇文章用于荟萃分析。统计研究采用了使用R.
    UNASSIGNED的固定效应和随机效应模型:SP和GP的血清阳性率是使用累积样本量为4352的研究计算的,其中绵羊和山羊的样本合计贡献了48%,其次是绵羊(32%)和山羊(21%)。元回归的结果显示,检测技术在5%水平(Qm=14.12)对总体效应大小具有显著影响。亚组分析的聚合酶链反应(PCR)测试与样品进一步分为两类基于中位数,它显示62%的样品使用PCR作为检测测试,然后是II组。
    未经批准:从研究中,结论是SP和GP疾病高度流行;因此,有效疫苗,通过推广活动对农民进行适当的教育,和跨界疾病移动限制对于控制和根除疾病是必要的。
    UNASSIGNED: Two endemic capripox infectious diseases, sheeppox (SP) and goatpox (GP) are common in Asia, Africa, and the Middle East. Sheep and goats, in general, are considered current assets of small and marginal farmers and have significant economic value in terms of meat, wool, and skin/hide production. Sheep and goat populations in India total 148.88 million and 74.26 million, respectively. Capripox caused US$ 2.3 million (Indian Rupee [INR] 105 million) in economic damages in Maharashtra (India) alone, and it took over 6 years for a flock to recover from the outbreak. The projected yearly loss at the national level is US$ 27.47 million (INR 1250 million). As a result, Capripox diseases put small and marginal farmers under much financial strain. The present study estimates the seroprevalence of SP and GP diseases in the Asian and African continents using systematic review and meta-analysis. The results of the study will help researchers and policymakers to understand the spatial and temporal distribution of the disease and its burden. In addition, the results are also helpful to design and implement location-specific prevention and eradication measures against these diseases.
    UNASSIGNED: Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines of Cochran collaborations were used for systematic review and subsequently meta-analysis were used. The literature was collected from various databases. Initial search string resulted in more than nine thousand articles for the period 2000 to 2020 using the different combinations of keywords and Boolean operators (or not) asterisk* and quotation marks. Out of 9398 papers, 80 studies were chosen for complete test reviews and quality bias evaluation using the inclusion and exclusion criteria. Finally, 21 articles were used for the meta-analysis. The statistical study employed fixed effects and random effects models using R.
    UNASSIGNED: Seroprevalence of SP and GP was calculated using studies with a cumulative sample size of 4352, out of which sheep and goats\' samples together contribute 48%, followed by sheep (32%) and goat (21%). The result of the meta-regression revealed that detection techniques had a significant impact on the overall effect size at 5% level (Qm=14.12). Subgroup analysis of polymerase chain reaction (PCR) test with samples was further grouped into two categories based on the median, and it revealed that 62% of samples used PCR as a detecting test followed by group-II.
    UNASSIGNED: From the study, it is concluded that SP and GP diseases are highly prevalent; hence, effective vaccines, proper education to farmers through extension activity, and transboundary disease movement restriction are necessary for the control and eradication of the disease.

    块状皮肤病(LSD)的地理分布,一种由卡痘病毒引起的经济上重要的牛病,达到了前所未有的程度。接种疫苗是防止感染在流行和新受影响地区传播的唯一方法。然而,如果爆发,选择最佳疫苗是兽医当局和农民面临的主要挑战。决策者需要可靠的科学信息来支持他们的决策和后续行动。可用的疫苗产品在质量方面有所不同,功效,安全,副作用,和价格。不同类型减毒活疫苗和灭活疫苗的利弊,疫苗接种策略,并讨论了相关风险。血清转换,通常在接种疫苗之后,对用于评估现场LSD疫苗接种活动有效性的工具和方法提出了具体要求。我们旨在全面更新可用的疫苗和针对LSD的疫苗接种,更好地准备受影响和风险国家控制LSD并确保牛的安全贸易。
    The geographical distribution of lumpy skin disease (LSD), an economically important cattle disease caused by a capripoxvirus, has reached an unprecedented extent. Vaccination is the only way to prevent the spread of the infection in endemic and newly affected regions. Yet, in the event of an outbreak, selection of the best vaccine is a major challenge for veterinary authorities and farmers. Decision makers need sound scientific information to support their decisions and subsequent actions. The available vaccine products vary in terms of quality, efficacy, safety, side effects, and price. The pros and cons of different types of live attenuated and inactivated vaccines, vaccination strategies, and associated risks are discussed. Seroconversion, which typically follows vaccination, places specific demands on the tools and methods used to evaluate the effectiveness of the LSD vaccination campaigns in the field. We aimed to give a comprehensive update on available vaccines and vaccination against LSD, to better prepare affected and at-risk countries to control LSD and ensure the safe trade of cattle.

    块状皮肤病,羊痘,山痘是牛的法定传染病,绵羊,和山羊,分别,由Capropoxvirus属病毒引起的。他们负责直接和间接的财务损失。这些损失是由动物死亡引起的,接种疫苗的发病率成本,以及对动物和动物产品贸易的限制。控制和根除病毒有赖于及早发现爆发,矢量控制,严格的动物运动,和疫苗接种仍然是最有效的控制手段。迄今为止,减毒活疫苗被广泛使用;然而,保护仍然存在争议。许多疫苗与绵羊的不良反应和不完全保护有关,山羊,和牛。还开发了许多基于组合和重组的疫苗。这里,我们回顾了针对每种反刍动物的羊痘病毒感染以及各自疫苗赋予的针对羊痘病毒的免疫力。我们还回顾了它们对异源感染的相关交叉保护。
    Lumpy skin disease, sheeppox, and goatpox are notifiable diseases of cattle, sheep, and goats, respectively, caused by viruses of the Capripoxvirus genus. They are responsible for both direct and indirect financial losses. These losses arise through animal mortality, morbidity cost of vaccinations, and constraints to animals and animal products\' trade. Control and eradication of capripoxviruses depend on early detection of outbreaks, vector control, strict animal movement, and vaccination which remains the most effective means of control. To date, live attenuated vaccines are widely used; however, conferred protection remains controversial. Many vaccines have been associated with adverse reactions and incomplete protection in sheep, goats, and cattle. Many combination- and recombinant-based vaccines have also been developed. Here, we review capripoxvirus infections and the immunity conferred against capripoxviruses by their respective vaccines for each ruminant species. We also review their related cross protection to heterologous infections.

    块状皮肤病,羊痘和山痘是家畜反刍动物的高影响疾病,对牛具有破坏性影响,流行地区的绵羊和山羊养殖业。在这篇文章中,我们回顾了当前的地理分布,疫情的经济影响,流行病学,卡痘病毒的传播和免疫。本文的特别重点是审查现有疫苗的使用情况,以调查资源需求和必须克服的挑战,以改善疾病控制和根除,以及开发更安全、更有效疫苗的进展。此外,讨论了疫苗效力的现场评估和痘病毒可用的基因组数据库。
    Lumpy skin disease, sheeppox and goatpox are high-impact diseases of domestic ruminants with a devastating effect on cattle, sheep and goat farming industries in endemic regions. In this article, we review the current geographical distribution, economic impact of an outbreak, epidemiology, transmission and immunity of capripoxvirus. The special focus of the article is to scrutinize the use of currently available vaccines to investigate the resource needs and challenges that will have to be overcome to improve disease control and eradication, and progress on the development of safer and more effective vaccines. In addition, field evaluation of the efficacy of the vaccines and the genomic database available for poxviruses are discussed.

    Sheep and goats occupy a premier place in the livestock industry and contribute significantly to the world economy. Their populations are threatened by a number of health hazards, among the most notable of which are goat pox and sheep pox. These diseases inflict substantial losses in terms of reduced productivity and lower quality of wool and leather. They pose a major obstacle to the intensive rearing of sheep and goats and considerably hamper international trade. A comprehensive knowledge of goat pox and sheep pox would help in the diagnosis, prevention and control as well as the management of these diseases in a proper and effective manner. Although the two diseases are easily identified from the clinical signs and host species affected, laboratory tests are needed for confirmation. A battery of simple but highly efficient diagnostic methods and reagents is available for goat pox and sheep pox. However, the best way to control these diseases is the prophylactic immunization of all susceptible animals with a potent and efficacious vaccine, especially in areas where these diseases are endemic.
