A person suffering from severe gastroenteritis may need fluids administered intravenously (directly into the bloodstream via a vein – the setup is often referred to as a ‘drip’).
What is the incubation period for most stomach viruses?
After initial (first) exposure, a person will usually get the stomach flu within 12-48 hours. 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.
What is the incubation for the stomach flu?
Infected people usually have an acute onset of vomiting with nonbloody diarrhea. The incubation period is 12–48 hours. Other symptoms include abdominal cramps, nausea, and sometimes a low-grade fever. Illness is generally self-limited, and full recovery can be expected in 1–3 days for most patients.
What IV fluids is best for gastroenteritis?
Ringer’s lactate IV fluid is preferred. If not available, use normal saline or dextrose solution. It is important to measure the amount of IV fluids delivered and measure the fluid lost as diarrhea and vomitus.
Is oral rehydration in pediatric patients with gastroenteritis more effective than parenteral rehydration?
EVIDENCE-BASED ANSWER. Oral rehydration therapy (ORT) results in approximately 4% higher risk of needing additional rehydration treatment compared with intravenous therapy in the inpatient setting, but no difference in the outpatient setting.

What is the importance of incubation period?
Knowing the incubation period of an infectious disease—the time from exposure to the causative agent to when symptoms first appear—can provide important information during an outbreak, including when infected individuals will be symptomatic and most likely to spread the disease.

In severe dehydration, intravenous fluid replacement is preferred, and may be lifesaving. It is especially useful where there is depletion of fluid both in the intracellular space and the vascular spaces.
