My son was in the hospital for 2 weeks and diagnosed with Human Torovirus. It caused erosions & ulcerations in teh stomach, duodenitis and exudate, & gastritis. All of the above triggered pancreatitis. They found no other positive results in all his testing. I was told that there wasn't a serum antibody test (to check for antibodies fighting the Human Torovirus). Plus, I can't find much about it on the internet. He didn't have diarrhea or fever, just vomiting and stomach pain. What do you know about this virus?
