Novel Langya henipavirus (LayV) has been detected in China; it has affected 35 human beings. Henipavirus are classified as biosafety level 4 pathogens; they can also cause severe illness in animals and humans. There are no licensed drugs or vaccines for humans.
The Henipavirus types identified before this included Hendra, Nipah, Cedar, Mojiang, and the Ghanian bat virus. According to the US CDC, the Cedar virus, Ghanian bat virus, and Mojiang virus are not known to cause any disease in humans. Still, Hendra and Nipah have affected humans and caused severe illness too.
This disease is known to cause fever, but scientists call for a deeper investigation of associated human illness. According to the scientist, Langya's genome organization is "identical to that of other Henipaviruses, and closely related to the Mojiang Henipavirus, which was discussed in Southern China."
And the symptoms of this disease are fever, fatigue, cough, nausea, headache, and vomiting.
