After seeing some rat dropping in the nesting boxes and food I tried to clean it out. I didn’t have on a mask at first and I am really hoping I haven’t exposed myself to hantavirus. Can anyone calm my fears about this? Do most people get it after heavy exposure or can you get it more easily than that? I have done some research and think they were roof rats. Are they the most common type of rat in Texas? Do they carry the virus?? Near Austin. Please help I’m very worried!
