“Stomach flu” is everyday English for viral gastroenteritis — usually norovirus, rotavirus, or adenovirus. It’s not influenza and it’s not food poisoning, though it can look like either. In Cabo, it spreads on cruises, in resorts, and through any setting where dozens of strangers share buffets and pools. A medical IV gets you through the worst of it without losing your vacation.
How to tell stomach flu from food poisoning
It can be hard to tell them apart at the moment you’re sick — both cause vomiting, diarrhea, cramps. A few clues:
- Onset: stomach flu usually 12–48 hours after exposure; food poisoning often within 1–6 hours of the suspect meal.
- Fever: stomach flu commonly has low-grade fever and body aches; food poisoning typically does not (Salmonella excepted).
- Diarrhea: stomach flu is watery and clear; bacterial food poisoning can be bloody.
- Contact: stomach flu often hits multiple people in a group (cruise outbreak); food poisoning usually traces to a meal.
The treatment overlaps significantly, so don’t worry about diagnosing yourself — that’s what the physician is for at intake.
What stomach flu does to your body
The virus inflames the lining of your stomach and small intestine, which both stops absorption and triggers fluid secretion into the bowel. You lose water, sodium, potassium, and chloride. Within hours you can be moderately dehydrated; within a day, severely so — especially in Cabo heat. Children, elderly travelers, and pregnant patients deteriorate fastest.
The IV protocol for viral gastroenteritis
At Cabo Quick Care a stomach-flu IV typically includes:
- 1–2 liters of lactated Ringer’s or normal saline — the volume your body has lost.
- Zofran (ondansetron) IV — prescription anti-nausea that breaks the vomiting cycle within 15–30 minutes.
- Magnesium and B-complex — replaces what you’ve lost; reduces the headache and weakness.
- Famotidine (Pepcid) IV — calms stomach acid and helps the nausea.
- Toradol IV when indicated — for cramping and body aches; not used with bleeding or kidney concerns.
Antibiotics are not part of routine viral gastro treatment. The doctor will only prescribe them if the picture changes to suggest bacterial superinfection.
Mobile IV at your hotel — or come into the clinic
Mobile IV is appropriate for most uncomplicated cases. Come into the clinic (or go to a hospital ER) if you have a fever above 102°F with severe symptoms, no urine output in 8+ hours, severe abdominal pain, bloody output, persistent vomiting beyond 24 hours, pregnancy with significant symptoms, or you are elderly with chronic conditions. The doctor screens for all of these at intake and may escalate to an ER via our medical transport service.
What to do until the IV arrives
- Small sips of water or oral rehydration solution every few minutes.
- Avoid milk, alcohol, fruit juice, soda — they make osmotic diarrhea worse.
- Bland foods (rice, toast, banana) if you can keep them down.
- Rest in a cool room. Cabo heat compounds dehydration fast.
- Wash hands thoroughly. Norovirus is extremely contagious — don’t share towels or food prep.
Stomach flu after a cruise stop in Cabo
Cruise outbreaks are common enough that we keep extra mobile IV slots open during peak weeks. If multiple travelers in your party are sick we can coordinate a group visit. See our cruise passenger IV page and our broader guide on IV for norovirus from a cruise.

Frequently asked questions
How long does stomach flu usually last?
24–72 hours for most adults. With a medical IV the worst hours pass faster, but the underlying virus runs its course.
Will an IV cure the stomach flu?
No — it does not kill the virus. It helps with fluid loss, electrolyte imbalance, nausea, and pain so your body can recover faster. (We don’t use the word cure.)
Can I get an IV at my hotel?
Yes, in most cases. Mobile IV is available across Cabo, the Tourist Corridor, and San José del Cabo with a physician on dispatch.
Is stomach flu contagious?
Highly. Norovirus persists on surfaces for days. Wash hands, isolate the sick person, and use bleach-based cleaning where possible.
