Brief Answer: unlikely to be the flu Detailed Answer: Hi,thanks for using healthcare magic Though it is understandable to be concerned regarding her possible exposure, based on the symptoms given, it is unlikely to be the H1N1 virus that caused your daughter's symptoms. H1N1 is a type of flu virus. At present, you stated that she is feeling better,the flu virus would produce symptoms for a lot longer. In addition, since it is a flu virus, there would normally be symptoms such as sore throat, cough, muscle aches and pain. Diarrhoea can occur as a result of the flu virus but normally in conjunction with the above symptoms. Diarrhoea can occur with other illnesses the most common are food intolerance or viral or bacterial infections of the gastrointestinal tract. The other causes are celiac disease, lactose intolerance, inflammatory bowel disease, hyperthyroidism. The fact that the illness lasted at 2 to 3 days makes flu unlikely and make it likely that is was related to a viral infection of the gastrointestinal tract. This would also cause a fever. I hope this helps, feel free to ask any other questions
