American health officials have identified a virus spread by insects in more than 20 people who visited Cuba. The virus is officially called Oropouche. It is also known as sloth fever. The U.S. Centers for Disease Control and Prevention (CDC) said August 27 it had received reports of 21 cases in the United States. All of the cases – 20 in Florida and one in New York – involved people who had traveled to Cuba. European health officials said they had identified 19 cases of the virus, nearly all of them in travelers. The CDC explains that Oropouche is usually spread through the bites of small flies called midges, as well as mosquitoes. Signs, or symptoms, of the sickness usually start three to 10 days after an insect bite. They can include headache, high temperature, joint stiffness, stomach problems and sensitivity to light. The CDC says most virus cases last from three to six days and people generally recover without any long-term effects. There is currently no specific treatment or vaccine for the sickness. The Oropouche virus is native to forested tropical areas. It was first identified in 1955 in the Caribbean island nation of Trinidad and Tobago. The virus was named after a nearby village and water system. The sickness is sometimes called sloth fever because scientists investigating the virus found it in a three-toed sloth. Researchers believed the sloths were important in spreading the virus between insects and animals. The virus is spread to humans by small biting flies called midges, and by some kinds of mosquitoes. Humans have become infected while visiting forested areas and are believed to be responsible for helping the virus make its way to towns and cities. So far, person-to-person transmission, or spread, has not been documented. The virus has recently caused large outbreaks in Amazon areas where it was known to exist. It has also been found in new areas of South America and the Caribbean. About 8,000 local infections have been reported in Bolivia, Brazil, Colombia, Cuba, and Peru. Most patients returning from Cuba reported their symptoms between May and July. Three of the patients were hospitalized, with no deaths reported, the CDC said in its Morbidity and Mortality Weekly Report. Symptoms can seem similar to other tropical diseases like dengue, Zika or malaria. The most common ones include fever, headaches and muscle pains. Some infected people also suffer from diarrhea, unsettled stomach, vomiting or skin reactions. Some patients can suffer symptoms repeatedly. And one in 20 people may experience more severe symptoms like bleeding, meningitis and encephalitis. The virus rarely causes death, although there were recent reports of deaths in two healthy young people in Brazil. There are no vaccines to prevent infections and no medicines are currently available to treat the symptoms.

四、背景知识
据央视新闻报道，当地时间8月27日，美国疾病控制和预防中心官网通报，截至2024年8月16日，美国共报告21例奥罗普切热病例，未出现死亡病例，且患者均有古巴旅行史。 “奥罗普切热是由奥罗普切病毒（Oropouche virus，OROV）引起的蚊媒传染病。奥罗普切病毒，是一种主要影响南美洲和北美洲人类的发热性疾病，该病由吸血的媒介昆虫如蚊、蠓等叮咬传播。”8月29日，华中科技大学附属同济医院感染科副主任医师郭威告诉人民日报健康客户端记者，目前还没有专门针对奥罗普切热的特效药或疫苗。 据世界卫生组织网站介绍，奥罗普切热其症状与登革热相似，包括高烧、头痛、肌痛、皮疹、关节痛和呕吐，通常持续3至6天，高达60%的病例会短暂复发。（背景知识来自于https://cj.sina.com.cn/articles/view/1411163204/541ca44402001exga）

美国卫生官员已经确认，在访问古巴的20多人中发现了一种通过昆虫传播的病毒。该病毒的正式名称是Oropouche病毒，也被称为树懒热。美国疾病控制与预防中心（CDC）在8月27日表示，他们已收到21例报告病例。所有病例——20例在佛罗里达州，1例在纽约——都涉及曾前往古巴的人员。欧洲卫生官员表示，他们已经确认了19例该病毒病例，几乎所有病例都发生在旅行者中。CDC解释说，Oropouche病毒通常通过一种叫做蠓的小型飞虫以及蚊子的叮咬传播。感染的症状通常在被昆虫叮咬后的三到十天内出现。症状可能包括头痛、高烧、关节僵硬、胃部不适以及对光敏感。CDC表示，大多数病毒病例持续三到六天，人们通常会康复且不会有长期影响。目前对这种疾病没有特定的治疗方法或疫苗。Oropouche病毒起源于热带森林地区。该病毒于1955年在加勒比海岛国特立尼达和多巴哥首次被发现。该病毒是以附近的一个村庄和水系统命名的。这种病有时被称为树懒热，因为科学家在研究该病毒时在三趾树懒身上发现了它。研究人员认为，树懒在病毒在昆虫和动物之间的传播中起到了重要作用。该病毒通过一种叫做蠓的小型咬人飞虫以及某些种类的蚊子传播给人类。人类在访问森林地区时感染病毒，并被认为是帮助病毒传播到城镇和城市的原因。到目前为止，还没有记录到人传人的传播方式。最近，该病毒在已知存在的亚马逊地区引发了大规模的爆发。它还被发现于南美和加勒比地区的新地区。目前在玻利维亚、巴西、哥伦比亚、古巴和秘鲁报告了约8000例本地感染。大多数从古巴返回的患者报告他们的症状发生在5月至7月之间。CDC在其《发病率和死亡率周报》中表示，其中三名患者住院治疗，但没有报告死亡病例。症状可能与其他热带疾病如登革热、寨卡或疟疾类似。最常见的症状包括发烧、头痛和肌肉疼痛。一些感染者还会出现腹泻、胃部不适、呕吐或皮肤反应。有些患者可能会反复出现症状。而20人中有一人可能会出现更严重的症状，如出血、脑膜炎和脑炎。该病毒很少引起死亡，但最近在巴西有两名健康的年轻人死亡的报告。目前没有预防感染的疫苗，也没有可用的药物来治疗症状。
