A new type of animal-derived Henipavirus (also named Langya henipavirus, LayV) that can infect humans has been found in East China's Shandong Province and Central China's Henan Province, and has so far infected 35 people in the two provinces, according to an article published in the New England Journal of Medicine (NEJM) by scientists from China and Singapore.
 

The new type of Henipavirus was found in throat swab samples from febrile patients in eastern China with a history of contact with animals in recent times, according to media reports.
 

Scholars who participated in the study pointed out that this newly discovered Henipavirus, which may have come from animals, is associated with some febrile cases, and the infected people have symptoms including fever, fatigue, cough, anorexia, myalgia, and nausea.
 

Further investigation found that 26 out of 35 cases of Langya henipavirus infection in Shandong and Henan provinces have developed clinical symptoms such as fever, irritability, cough, anorexia, myalgia, nausea, headache and vomiting.
 

Henipavirus is one of the important emerging causes of zoonosis in the Asia-Pacific region, Shanghai-based media thepaper.cn reported, noting that both Hendra virus (HeV) and Nipah virus (NiV) from this genus are known to infect humans with fruit bats as the natural host of both viruses.
 

Henipavirus can cause severe disease in animals and humans and are classified as biosafety Level 4 viruses with case fatality rates between 40-75 percent, according to the data from World Health Organization (WHO), highlighting that this is much higher than the fatality rate of the coronavirus.
 

However, there is currently no vaccine or treatment for Henipavirus and the only treatment is supportive care to manage complications.
 

山东、河南新发现“琅琊病毒”可人畜共患

近日,全球权威医学杂志《新英格兰医学》发表了一项中国和新加坡科学家合作的通讯文章,称在中国山东和河南两地发现了一种可感染人类的新的动物源性亨尼帕病毒,作者将其命名为琅琊病毒,感染者症状包括发热、乏力、咳嗽、厌食、肌痛、恶心等。
 

这种新发现的病毒,传播力和致病力如何?它是从哪儿来的?对此,解放日报•上观新闻记者邀请复旦大学附属华山医院感染科副主任医师王新宇答疑解惑。
 

王新宇介绍,此前,人类已发现五种亨尼帕病毒,其中包括在澳大利亚东海岸发现的亨德拉病毒,和在东南亚发现的尼帕病毒,这两种病毒反复出现人类感染和暴发流行,病死率高达40%至75%,但从未在我国国内被报告过。亨尼帕病毒属中还有一名成员——墨江病毒,最早于2012年在我国云南省墨江哈尼族自治县被分离出来,当时报告了3名感染者死亡。本次发现的琅琊病毒,是已知的第6种亨尼帕病毒。
