Chinese epidemiologists are closely monitoring the appearance of people infected with a new virus, Langya virus, in the east of the country.
In a correspondence toscientists from Beijing Institute of Microbiology and Epidemiology, in China, share a news that recalls the beginning of the of Covid-19. In the provinces of Henan and Shandong, 35 people have been infected with a new virus of the genus Henipavirus, called Langya (LayV), between January 2019 and January 2021.
A novel RNA virus of its kind Henipavirus
It is a viruswrapped whose makes about 18,000 and code six structural. Among the 35 patients, 26 were only infected with the Langya virus – the others had other infectious diseases. Thus, the analysis of the symptoms caused by the virus was only made on these 26 patients. All patients presented with fever (100%), followed by fatigue, cough and muscular for half of them. Some also suffered from nausea, headaches and vomiting.
Although the Langya virus appears to be solely responsible for the symptoms presented by the patients, it does not fulfill all the criteria of theof Koch, a set of rules issued by in the 19the century and readapted since, which make it possible to identify with certainty the etiological agent of a disease.
No proven human-to-human contamination
No human-to-human transmission has been demonstrated at this stage. The cases identified are not geographically restricted and the survey of patients does not reveal close contact with other patients. On the other hand, theappears to be of animal origin. Three goats and four among the hundreds tested, have directed against the Langya virus. On the other hand, studies carried out on the wild designate shrews as the natural reservoir of the virus.
Genre Henipavirus is not unknown to epidemiologists since it contains two other zoonotic viruses known to cause severe and even fatal disease in someof which the human being: the and Hendra, both present naturally .
