Hantavirus is out there, but the focus of people, the government, and the medical world are at the Covid-19. We don't know if Hantavirus is dangerous or not, but the rats transmit it to people who don't take care their clean, and it is related to the clean of our environment and of course, our home. Just make sure you have cleaning everything in your house so the rats will not come to your home. Be careful with the rats by clean up your table from the food.
It's not that we're just focused on one thing and not another because of priorities, we're just focused on the Coronavirus because it has come out of left field, has a pretty high mortality rate for those that are in the high risk groups (older, diabetes, heart issues, etc) We don't have much research on the Coronavirus as well, while we have a good amount of research on the Hantavirus.
The Hantavirus is something that we've had outbreaks on and we know how to ensure that it won't spread. Not the same regarding the Coronavirus.
