Monkeypox, a rare zoonotic disease, is primarily prevalent in Central and Western Africa. However, monkeypox is emerging as a worldwide concern due to the 2022 monkeypox outbreak, which is the first instance of widespread community transmission outside Africa. Monkeypox is caused by the monkeypox virus, which belongs to the genus Orthopoxvirus and presents as a vesicular-pustular disease that may be preceded by fever, malaise, and other constitutional symptoms. If present, lymphadenopathy may distinguish it from chickenpox or smallpox. However, contrary to previous manifestations, most monkeypox patients presented with atypical features during the 2022 outbreak. Monkeypox is usually a self-limiting disease with symptoms lasting between 2 weeks and 4 weeks and is mainly transmitted when a person comes into contact with an infected animal, person, or fomites contaminated with the virus. Very few treatment options are available for this disease. Tecovirimat has been licensed in some countries for the treatment of smallpox and monkeypox infections. Two other medications, cidofovir and brincidofovir, have been found to be effective against poxviruses in in vitro and animal studies, but data on human cases of monkeypox are limited. Although Imvamune (JYNNEOS), a vaccine against monkeypox, is authorized in the United States, there are currently no established routine vaccination programs. Current preventive strategies focus on the detection of probable cases and containment of the outbreak through the implementation of selected ring vaccination programs. Fundamental principles to prevent the spread of monkeypox, including maintaining personal hygiene and avoiding close contact with symptomatic patients, are of paramount importance.
猴痘是一种罕见的人畜共患疾病,主要流行于中非和西非。然而,由于 2022 年猴痘疫情的爆发,猴痘已成为全球关注的问题,这是非洲以外地区首次广泛社区传播。猴痘是由猴痘病毒引起的,该病毒属于正痘病毒属,表现为水疱脓疱病,可能伴有发热、不适和其他全身症状。如果存在淋巴结病,可能与水痘或天花相区别。然而,与以往的表现不同,在 2022 年的疫情中,大多数猴痘患者表现出非典型特征。猴痘通常是一种自限性疾病,症状持续 2 周至 4 周,主要通过接触受感染的动物、人或被病毒污染的污染物传播。针对这种疾病,目前只有很少的治疗选择。特考韦瑞在一些国家被许可用于治疗天花和猴痘感染。另外两种药物西多福韦和溴夫定在体外和动物研究中被发现对痘病毒有效,但关于人类猴痘病例的数据有限。尽管美国授权使用 Imvamune(JYNNEOS)疫苗预防猴痘,但目前尚无常规接种计划。当前的预防策略侧重于发现疑似病例,并通过实施有选择的环形疫苗接种计划来控制疫情。预防猴痘传播的基本原则,包括保持个人卫生和避免与有症状的患者密切接触,是至关重要的。
