Hantaviral sequences were recovered from the lung tissue of an Asian house rat ( captured in Serang, Indonesia. Phylogenetic analysis of partial L, M and S segment sequences showed that they belonged to a novel hantavirus provisionally named Serang virus (SERV). Notably, SERV is distinct from the hantaviruses associated with rodents of the species : Seoul virus associated with worldwide and Gou virus isolated from in China. Instead SERV appeared more closely related to Thailand virus (THAIV) carried by the great bandicoot rat (). These results suggest the possibility that SERV originated via host-switching, with a possible scenario of (pre)-THAIV ‘jumping’ from (pre)bandicoots to rats and colonizing this new host species.
