With swine flu - can you have typical flu like symptoms (pyrexia >38.5, myalgia, headache etc) ...but with dominant abdominal symptoms of anorexia and cramps and a minimum of respiratory symptoms? (Other causes for the abdominal symptoms having been reasonably excluded by investigation)

In other words can the route of infection be mainly via the GI tract, rather than the resp tract (as much more commonly occurs) and thus produce a dominant GI picture?

Most animal studies on swine flu patterns of virus spread within the body seem to focus on an initial introduction of the virus into the nasal cavities - rather unsurprisingly the ensuing symptoms and patterns of infection are mainly respiratory. Comments welcome...
