Scientists display a remarkable solicitude as they discover a new, animal-derived virus in states of Eastern China, which already happened to have infected over 35 patients in the northeastern provinces of Shandong and Henan, since 2018.

This virus has been found in throat swab samples from pyretic patients. According to the reports, manly farmers seemed to have been infected. Others have shown signs of blood cell abnormalities and liver and kidney damage.

Novel Langya Virus

There is no evidence so far about its transmission among human beings. The virus has also not caused any death yet.

The virus seemed to have been transmitted through zoonosis. Researchers tested goats, dogs, pigs, and cattle living in the villages of infected patients for antibodies against Langya Henipavirus (LayV) and took tissue and urine samples from 25 species of wild small animals. They found LayV antibodies in a handful of goats and dogs and identified LayV viral RNA in 27% of the 262 sampled shrews. This suggested that shrews are the reservoir of the virus.

The LayV genome is most closely related to Mojiang Henapivirus, which was first isolated in rats. Henipavirus has a single-stranded RNA genome with a negative orientation. It belongs to the family of viruses which also includes measles, mumps, and other respiratory viruses that infect people. It also forms an emerging cause of zoonosis in the Asia Pacific region. The virus holds a biosafety Level 4 virus classification with a 40-75% fatality rate.

Throughout the study period, researchers found ranging symptoms,

  • Pneumonia
  • Fever
  • Fatigue
  • Loss of appetite
  • Aches
  • Irritability
  • Anorexia
  • Myalgia
  • Nausea


Even though scientists could find the origin of the virus, the origin of transmission is still unclear. A lot of research is still required to be more certain. Besides, scientists did not find any strong evidence of it spreading among people and also didn’t find anything alarming. But still, some scientists urge the need for a global surveillance system to check for more such zoonotic virus spillovers.
