    猴痘病毒(MPX)属于Poxviridae家族的正痘病毒属,在非洲部分地区流行,并在人类中引起类似天花的疾病。最近的MPX疫情已经影响到110个国家,自2022年5月以来,已确诊病例86,956例,因此已成为人们关注的焦点。特别是,对病毒的分子理解对于研究感染过程和病原体-宿主相互作用至关重要,预测向性变化,或在非常早期的阶段指导药物开发和药物发现以及疫苗开发或疫苗适应。在这里,我们对目前正在流行的MPX的结构蛋白质组进行了研究:我们对爆发后一年内采样的3,713个基因组序列进行了一致分析,发现了10,580个特征性候选开放阅读框(ORF).在非冗余蛋白质数据库中的搜索将可疑ORF的数量减少到1,079个,其中210个是典型的MPX参考基因组中的代表性蛋白质。这应该作为目前传播的MPX中推定的蛋白质的集合,一种可以支持及时发现药物的信息组合,突变分析,和疫苗开发。我们,在这里,通过提供210种蛋白质的原子3D模型,呈现迄今为止最全面的结构蛋白质组,用三种最先进的结构预测方法生成,包括蛋白质组的突变分析,特别关注tecovirimat和brincidofovir的药物结合位点。重要性2022年爆发的猴痘病毒已经涉及,截至2023年4月,110个国家有86,956例确诊病例和119例死亡。在分子水平上了解新出现的疾病对于研究感染过程并最终指导早期药物发现至关重要。为了支持这一点,我们提供了迄今为止最全面的猴痘病毒结构蛋白质组,其中包括210个结构模型,每种都使用三种最先进的结构预测方法进行计算。而不是建立在单基因组序列上,我们从疫情爆发后1年内从患者中抽取的3,713份高质量基因组序列的共识中生成了我们的模型.因此,我们展示了目前分离的病毒的平均结构蛋白质组,包括特别关注药物结合位点的突变分析。在这里提出的结构蛋白质组中的持续动态突变监测对于及时预测进化病毒中可能的生理变化至关重要。
    OBJECTIVE: The 2022 outbreak of the monkeypox virus already involves, by April 2023, 110 countries with 86,956 confirmed cases and 119 deaths. Understanding an emerging disease on a molecular level is essential to study infection processes and eventually guide drug discovery at an early stage. To support this, we provide the so far most comprehensive structural proteome of the monkeypox virus, which includes 210 structural models, each computed with three state-of-the-art structure prediction methods. Instead of building on a single-genome sequence, we generated our models from a consensus of 3,713 high-quality genome sequences sampled from patients within 1 year of the outbreak. Therefore, we present an average structural proteome of the currently isolated viruses, including mutational analyses with a special focus on drug-binding sites. Continuing dynamic mutation monitoring within the structural proteome presented here is essential to timely predict possible physiological changes in the evolving virus.

    2022年5月,世界卫生组织宣布全球范围内的痘病毒(MPXV)爆发。由于疫苗接种协议的广泛实施和一般人群的认识提高,自2023年3月以来,水痘(以前称为猴痘)的发病率显着下降。然而,重要的是要记住,水痘有可能影响人类的多种生理系统,包括心血管,胃肠,耳朵/鼻子/喉咙,和眼部系统。水痘病的死亡率相对低于天花。然而,重要的是要注意,这种疾病仍然可能导致重大的全身性后果。目前正在研究病毒影响各种生理系统的特定病理生理机制。通过粘膜损伤或鼻内暴露直接接种,直接病毒毒性,通过精液的淋巴传播都是可行的假设。迅速认识到此类并发症对于降低发病率和死亡率至关重要。
    In May of 2022, the World Health Organization declared a worldwide Mpox virus (MPXV) outbreak. Due to the widespread implementation of vaccination protocols and heightened awareness among the general population, there has been a notable decline in the incidence of Mpox (formerly known as Monkeypox) cases since March 2023. Nevertheless, it is crucial to remember that Mpox has the potential to impact multiple physiological systems in humans, encompassing the cardiovascular, gastrointestinal, ear/nose/throat, and ocular systems. The mortality rate of the Mpox disease is comparatively lower than that of smallpox. However, it is essential to note that this disease can still lead to significant systemic consequences. The specific pathophysiological mechanisms by which the virus affects various physiological systems are now being investigated. Direct inoculation through mucosal damage or intranasal exposure, direct viral toxicity, and lymphatic transmission via the seminal fluid are all viable hypotheses. The prompt recognition of such complications is crucial to decrease morbidity and mortality.

    猴痘是一种人畜共患疾病。自从1970年发现第一例人类猴痘病例以来,它在非洲中部和西部的一些国家一直很普遍。自2022年5月以来,在全球96多个非地方病国家和地区报告了猴痘病例。截至2022年9月14日,已有58,200多例人类猴痘病例,还有社区传播。1980年停止了天花疫苗接种,这与猴痘有一些交叉保护作用,导致对猴痘缺乏免疫力,这引起了全球的关注和警惕。截至2022年9月14日,中国有4例猴痘病例,其中三个在台湾省,一个在香港。以前的国外研究表明,儿童容易患猴痘,并且也有很高的严重疾病或并发症的风险。为了提高儿科医生对猴痘的认识并实现早期发现,早期诊断,早期治疗,和早期处置,我们组织了全国权威儿科感染专家,呼吸,皮肤病学,重症监护医学,传染病,以及公共卫生和其他方面来制定这个专家共识,根据世界卫生组织最新发布的“猴痘的临床管理和感染预防与控制”,中华人民共和国国家卫生健康委员会发布的《猴痘诊疗指南(2022版)》等相关文件。在这种共识的发展过程中,多学科专家多次论证病因,流行病学,传输,临床表现,实验室检查,诊断,鉴别诊断,治疗,排放标准,预防,处置过程,以及可疑和确诊病例的预防和控制要点。
    Monkeypox is a zoonotic disease. Since the first human monkeypox case was detected in 1970, it has been prevalent in some countries in central and western Africa. Since May 2022, monkeypox cases have been reported in more than 96 non-endemic countries and regions worldwide. As of September 14, 2022, there have been more than 58,200 human monkeypox cases, and there is community transmission. The cessation of smallpox vaccination in 1980, which had some cross-protection with monkeypox, resulted in a general lack of immunity to monkeypox, which caused global concern and vigilance. As of September 14, 2022, there are four monkeypox cases in China, including three in Taiwan province and one in Hong Kong city. Previous foreign studies have shown that children are vulnerable to monkeypox and are also at high risk for severe disease or complications. In order to improve pediatricians\' understanding of monkeypox and achieve early detection, early diagnosis, early treatment,  and early disposal, we have organized national authoritative experts in pediatric infection, respiratory, dermatology, critical care medicine, infectious diseases, and public health and others to formulate this expert consensus, on the basis of the latest \"Clinical management and infection prevention and control for monkeypox\" released by The World Health Organization, the \"guidelines for diagnosis and treatment of monkeypox (version 2022)\" issued by National Health Commission of the People\'s Republic of China and other relevant documents. During the development of this consensus, multidisciplinary experts have repeatedly demonstrated the etiology, epidemiology, transmission, clinical manifestations, laboratory examinations, diagnosis, differential diagnosis, treatment, discharge criteria, prevention, disposal process, and key points of prevention and control of suspected and confirmed cases.

    虽然2019年冠状病毒病的大流行仍在继续,自2022年5月以来,猴痘在非流行国家迅速传播。准确和快速的实验室测试对于识别和控制猴痘至关重要。韩国实验室医学学会和韩国疾病预防和控制机构提出了在韩国临床实验室中诊断猴痘的指南。这些指南涵盖了测试的类型,标本的选择,采集标本,诊断方法,测试结果的解释,和生物安全。分子测试被推荐作为确认测试。建议皮肤病变标本在症状阶段进行测试,建议在症状前或前驱阶段收集血液和口咽拭子。
    While the coronavirus disease 2019 pandemic is ongoing, monkeypox has been rapidly spreading in non-endemic countries since May 2022. Accurate and rapid laboratory tests are essential for identifying and controlling monkeypox. Korean Society for Laboratory Medicine and the Korea Disease Prevention and Control Agency have proposed guidelines for diagnosing monkeypox in clinical laboratories in Korea. These guidelines cover the type of tests, selection of specimens, collection of specimens, diagnostic methods, interpretation of test results, and biosafety. Molecular tests are recommended as confirmatory tests. Skin lesion specimens are recommended for testing in the symptomatic stage, and the collection of both blood and oropharyngeal swabs is recommended in the presymptomatic or prodromal stage.
