Let’s pretend this particular strain of hantavirus is some new variant that could potentially spread rapidly to people just in your proximity.
It’s not, but let’s pretend.
Hantavirus is typically contracted by inhaling airborne particles from infected rodent urine, droppings, or saliva. It also doesn’t spread from human to human. Except for one rare type called the Andes variant, which only infects person to person from prolonged exposure. Significant close contact.
So hypothetically, if this hantavirus “outbreak” is a variant that not only spreads from human to human, but is also contagious enough that it doesn’t require prolonged exposure, then the odds of it being manmade would be fairly high.
At least that’s my take on it. It doesn’t seem like it’s even scientifically possible for this to happen based on what I’ve read about it, so unless humans tampered with it in a lab, there’s basically zero chance of this becoming a pandemic or even an issue worthy of attention.
