diarrhea incubation period - transmission to symptoms
Incubation Period, Diagnosis/Symptoms and Immunity â¢ After initial (first) exposure, a person will usually get the stomach flu within 12-48 hours. â¢ The stomach flu is diagnosed based mostly on symptoms, including nausea, vomiting, diarrhea, muscle aches, abdominal cramps, and no fever or a low-grade fever. Vomiting and diarrhea can occur separately or together. Symptoms usually last 24-60 hours, but the virus may be present in a personâs stool for up to two weeks longer. Complications, including death, are rare. They usually occur in elderly persons with underlying chronic diseasesâand most often are due to dehydration.
