diarrhea is not a symptom that is consistent with influenza. influenza is a respiratory disease with fever (yes it can be as high as 103) and coughing; body aches chills etc. if your daughter is having severe diarrhea influenza is not the cause and a flu vaccine would not have prevented this gastroenteritis. she most definitely picked up a pathogen of some sort usually a virus but she will need to see a medical provider for a proper examination.
can an adult have 103 fever with the flu? . my 40 year old daughter came back from israel warsaw and jordan saturday evening. started feeling sick monday morning had 102 fever monday evening had severe diarrhea tuesday went down last night to 99 with taking advil every 6 hours. this morning wednesday she has 103. 1 fever. she had the flu shot. do adults run that high a fever with the flu? do you think she picked up something when out of the country? i am very worried.
