| Four of the 11 patients who developed anthrax in 2001 initially were misdiagnosed with viral syndrome, bronchitis, or gastroenteritis. |
| Gene sequencing showed that it was derived from the porcine transmissible gastroenteritis virus by the loss of a sizeable chunk of RNA from one of its genes. |
| One parent said her daughter and classmates had suffered several bouts of gastroenteritis, due to the lack of soap and hand driers. |
| Acute diarrhoea was rare in these sections, and no outbreaks of gastroenteritis were recorded. |
| In most cases, gastroenteritis is a mild illness caused by a viral infection and clears up without the need for medical treatment. |
| The only acute illnesses not detected were acute gastroenteritis, gastrostomy infection and seizure. |
