Tested negative for strep have a real bad sore throat high fever for 2 days what type of virus is this? and how do i beat it.

Sore throat: It could be any kind of virus causing the symptoms described by you. It usually takes more than 2 days to disappear. I would wait at least another couple of days to see if you need further work up. Until then, push fluids, salt water gargles. Acetaminophen or Ibuprofen for pain and fever and rest if you need. Soft foods, avoid hot/cold liquids or anything hard to swallow.
