It was identified in 35 patients from 2018 to August 2022 (average age 60) causing symptoms such as fever, fatigue and cough[2][4],[5]. More than a third of patients also have liver failure[6]. No deaths due to LayV have been reported (August 2022)[7][8]. Langya virus affects species such as humans, dogs, goats and its presumed original host, shrews (a quarter of which carry the virus)[2],[9]. The 35 cas were not in contact with each other and it is not known as of August 2022 if the virus was capable of human-to-human transmission[8],[10].
