Keeping food safe is vital to stop stomach viruses. We need to handle and prepare food correctly:

• Wash fruits and vegetables thoroughly before eating
• Cook shellfish well to kill viruses
• Avoid eating food or drinks made by sick people
• Keep food at the right temperature to stop bacteria from growing

When eating out, pick places with good hygiene scores. If you’re cooking for others, stay home if you’re sick.

Environmental Cleaning and Disinfection

Cleaning and disinfecting the environment is important to fight norovirus. Use 1:10 bleach to water to clean surfaces, where sick people have been. Focus on:

• Toilet handles and nearby areas
• Door handles and light switches
• Kitchen counters and sinks
• Any surface that may have come into contact with vomit or feces

Cleaning and disinfecting often can lower the risk of spreading the virus. Wash clothes and bedding that got vomit or feces in hot water and detergent.

By using these prevention steps, we can fight the 2025 stomach virus wave together. Staying informed and acting early are key to keeping ourselves and others healthy.

Treatment Options for Current Gastrointestinal Infections

Norovirus and other GI viruses are on the rise. It’s key to manage symptoms and know when to see a doctor. Knowing the treatment options for GI infections is vital for good care.

Managing Symptoms at Home

For norovirus and GI infections, treating symptoms at home is the first step. Staying hydrated is critical to avoid dehydration. Drink lots of water, clear broths, or oral rehydration solutions.

Rest well and eat a bland diet. Avoid spicy or fatty foods that can upset your stomach.

Over-the-counter meds can help. Anti-diarrheal meds can lessen diarrhea, and anti-nausea meds can stop vomiting. But, always check with a doctor before taking any meds, esp. for kids or those with health issues.

When to Seek Medical Attention

Most GI infections can be treated at home. But, some cases need a doctor’s help. Look for signs of severe dehydration like too much thirst, dark urine, or feeling dizzy.

Also, watch for bloody stools, severe belly pain, or a fever over 101.5°F (38.6°C). Certain groups, like older adults, young kids, pregnant women, and those with weak immune systems, should see a doctor quickly.

Knowing how to handle symptoms at home and when to see a doctor helps us deal with GI virus outbreaks.
