The cases of Langya virus, a new type of henipavirus, were documented from 2018 to 2021. There are no signs of human-to-human spread.
But the virus infecting the patient was genetically distinct from the other henipaviruses scientists had seen before. It came from a novel pathogen now known as Langya virus.
Still, other henipaviruses that spread from animals to humans can cause severe outcomes. Hendra virus, which can lead to respiratory illness or brain inflammation, has a"This is from a family of viruses that we know are concerning, and it appears that this group has now added a new lineage of viruses that are capable of severe disease," said Vaughn Cooper, an evolutionary biology professor at the University of Pittsburgh who wasn’t involved in the research.
"There are clearly repeated transmission events from what looks to be a common reservoir in shrews," Cooper said."The team did a very nice job of evaluating alternatives and finding that as the most likely explanation." Flying foxes are fruit bats, and Hendra and Nipah virus are known to originate in them. In the case of Hendra virus, the virus is usually passed from bats to horses; it then infects humans through the animals' excretions or bodily fluids.
