The
Miniopterus bat is a bent-winged bat found throughout Asia and the Middle East. Isolates of Miniopterus Bat CoV-1 have not been found in humans. Bat-CoV-1A and 1B have been also isolated from
Miniopterus magnater and
Miniopterus pusillus in Hong Kong. Phylogenetic analysis revealed that these group 1 bat coronaviruses have descended from a common ancestor. The four different but closely related group 1 alphacoronaviruses (bat-CoV 1A, 1B, HKU7 and HKU8), have been isolated from otherwise healthy bats which suggests that these viruses are well established in these species. ==Transmission==
