<s>[INST] Hi there, my daughter came home from camp 5 days ago with a nasty stomach bug, two days later she is fine but now my wife is Ill. My wife had the same symptoms,  fever 101/102 dierria and general feeling bad. Today she was feeling much better but this evening right after a refreshing shower her temp spiked to 103. And she had uncontrollable shivers. This lasted about an hour then let up. Her temp is now in the 101.5 range.Whats up with the sudden spike after feeling ok form the better part of the day? Thanks [/INST] Hello, Diarrhoea with high fever and generalized malaise suggest presence of a stomach infection. It requires treatment with antibiotics. If your wife is not allergic to fluoroquinolones group of medicines, I suggest she should start with Norfloxacin 400 mg twice a day for five days. She can take ibuprofen 400 mg or Acetaminophen 500 mg for symptomatic relief from fever. As the infection will resolve, the fever and malaise will disappear. She should stay light on diet for a few days and avoid outside or junk food.  Chat Doctor.  </s>
