The interesting (and concerning) part is that hantavirus was previously believed not to be transmissible from person to person. But with the recent outbreak, this understanding might have to be updated.
No, the Andes virus is known to be the only hantavirus that is transmissible from human to human. A South African lab confirmed the British passenger was infected by Andes virus.
This strain was already known for person to person transmission. In the south of Argentina we had a big outbreak after a sick person went to a birthday party in 2019.
