Stomach Bug Season: What's Going Around and When to Visit Urgent Care

Norovirus and stomach viruses are surging this winter here's what you need to know

If it seems like everyone around you is dealing with a stomach bug, you're not imagining it. Winter is peak season for norovirus and other stomach viruses, and cases are climbing across Texas, Arkansas, Oklahoma, and Louisiana.

At HealthCARE Express, we're seeing an uptick in patients with nausea, vomiting, diarrhea, and stomach cramps. Here's what you need to know about the stomach bugs going around, how to care for yourself at home, and when it's time to seek medical attention.

What's Going Around Right Now?

Norovirus: The Winter Vomiting Bug

Norovirus is the most common cause of stomach bugs, especially during winter months. Often called "stomach flu" (though it's not related to influenza), norovirus is highly contagious and spreads rapidly through families, schools, workplaces, and communities.

Key facts about norovirus:

Peak season: December through April
Highly contagious (just 10-100 viral particles can cause infection)
Spreads through contaminated food, water, surfaces, and person-to-person contact
Can survive on surfaces for days or even weeks
No vaccine or specific antiviral treatment available

Other Stomach Viruses

While norovirus is the most common culprit, other viruses can cause similar symptoms:

Rotavirus (more common in children)
Adenovirus
Astrovirus

Common Symptoms of Stomach Bugs

Stomach virus symptoms typically come on suddenly and can include:

Nausea and vomiting (often severe and sudden onset)
Diarrhea (watery, non-bloody)
Stomach cramps and abdominal pain
Low-grade fever (usually under 102°F)
Body aches
Headache
Fatigue and weakness
Chills

Typical timeline:

Symptoms appear 12-48 hours after exposure
Illness usually lasts 24-72 hours
You can be contagious for up to 2 weeks after symptoms resolve

Stomach Bug vs. Food Poisoning: How to Tell the Difference

Both can cause similar symptoms, but there are some key differences:

Stomach Bug (Viral Gastroenteritis)

Symptoms develop 12-48 hours after exposure
Lasts 1-3 days
Often affects multiple people over several days
Vomiting is usually prominent

Food Poisoning (Bacterial)

Symptoms develop 1-6 hours after eating contaminated food
Can last several days to a week
Usually affects people who ate the same food at the same time
Diarrhea is often more severe
May include bloody stool or high fever

If you're unsure which you're dealing with, our team at HealthCARE Express can help determine the cause and appropriate treatment.

Home Care: How to Treat a Stomach Bug

Most stomach bugs resolve on their own with supportive care at home. Here's what to do:

1. Stay Hydrated (Most Important!)

Vomiting and diarrhea can quickly lead to dehydration. Focus on:

Small, frequent sips of clear liquids (water, ice chips, clear broth)
Electrolyte drinks (Pedialyte, sports drinks, oral rehydration solutions)
Avoid sugary sodas, fruit juices, and caffeinated beverages (can worsen diarrhea)

Hydration goal: Aim for at least 8-10 cups of fluid per day, more if you're losing fluids rapidly

2. Rest Your Stomach

Wait 15-30 minutes after vomiting before trying to drink
Start with small sips (1-2 tablespoons every 15 minutes)
Gradually increase as tolerated

3. Ease Back Into Eating

Once vomiting subsides (usually after 8-12 hours), try the BRAT diet:

Bananas
Rice
Applesauce
Toast

Other gentle foods:

Plain crackers
Plain pasta
Boiled potatoes
Chicken broth
Oatmeal

Avoid for 24-48 hours:

Dairy products
Fatty or fried foods
Spicy foods
Raw fruits and vegetables
Caffeine and alcohol

4. Get Plenty of Rest

Your body needs energy to fight the virus. Rest as much as possible and avoid strenuous activity until you're fully recovered.

5. Manage Symptoms

Use a heating pad or warm compress for stomach cramps
Take acetaminophen (Tylenol) for fever or body aches if needed
Avoid ibuprofen or aspirin on an empty stomach (can irritate the stomach lining)
