This is an old found virus. Transmitted from Rodents. It has not shown as contagious behavior as per data available. There are vaccines also for it. There were many records of it in past also.
Don't panic & don't forward.
So they spread mainly by rodents.
There are no documentation of HPS Human to Human transmission. Whereas HFRS Human to Human Transmission are rare. Which means mostly non-contagious.
All sourced from CDC.
So many virus from this family are there. Again some vaccines are already there; depending upon which virus eg Hantavax. Some Hantavirus vaccine trials are still ongoing.
