Norovirus is one of the most common causes of viral gastroenteritis, often referred to as the “stomach bug.” It spreads easily through contaminated food, water, and surfaces. While it’s usually short-lived, the symptoms can be pretty unpleasant. Many people wonder: does norovirus require medical treatment? The good news is that most cases resolve on their own, but symptoms can be severe, and knowing when to seek medical attention is crucial.

If you’re feeling under the weather and experiencing symptoms of norovirus, AFC Urgent Care Waltham is here to help. Although there is no medication or treatment for norovirus other than symptom support, our board-certified medical providers can assist with symptom management and support for complications such as severe dehydration. The clinic is open every day from 8am to 8pm. Simply walk in when it’s convenient or save your spot online in advance below.

Understanding Norovirus

Norovirus is a highly contagious virus that inflames the stomach and intestines, leading to sudden vomiting and diarrhea. It’s notorious for spreading quickly in enclosed spaces such as schools, hospitals, cruise ships, and nursing homes. The infection can occur year-round, but is most common during the colder months.

Once exposed, symptoms typically appear within 12 to 48 hours. The virus can survive on surfaces for days, making hand hygiene and disinfection essential to prevent further spread.

Symptoms

Norovirus symptoms can appear abruptly and include:

• Nausea and vomiting
• Watery diarrhea
• Stomach cramps or pain
• Mild fever
• Muscle aches and fatigue
• Headache

Most people recover within two to three days, but dehydration is a key concern. Signs of dehydration include dizziness, dry mouth, decreased urination, and, in children, fewer wet diapers or crying without tears.

Managing Symptoms at Home

Norovirus doesn’t require antibiotics, since it’s a viral infection. However, it can cause severe dehydration, particularly in young children, older adults, and people with weakened immune systems. In most cases, norovirus can be managed at home with supportive care. The main goal is to stay hydrated and replace lost fluids and electrolytes.

At-home care tips to manage norovirus symptoms include:

• Drink plenty of fluids such as water, oral rehydration solutions, or clear broths
• Avoid caffeine, alcohol, and sugary drinks, which can worsen dehydration
• Eat bland foods like toast, bananas, rice, and applesauce once vomiting subsides
• Rest to help your immune system recover
• Keep good hygiene by washing hands frequently and disinfecting surfaces
• Over-the-counter medications like anti-diarrheal drugs should only be taken under a doctor’s advice, especially for children or older adults

Prevention and Protection

Preventing norovirus infection starts with good hygiene and food safety practices.

Some helpful tips include:

• Wash your hands thoroughly with soap and water, especially before eating or preparing food
• Disinfect contaminated surfaces using a bleach-based cleaner
• Wash fruits and vegetables properly
• Avoid preparing food for others if you’re feeling unwell
• Launder contaminated clothing and bedding immediately
