Winter Vomiting Bug

The winter vomiting bug, also known as norovirus, is a highly contagious virus that causes gastrointestinal illness.

Causes and Transmission

Norovirus is spread through:

• Close contact with someone who has the virus
• Contaminated food and water
• Touched surfaces or objects that have the virus on them, and then touching your mouth

Symptoms

Common symptoms of norovirus include:

• Sudden onset of vomiting
• Diarrhea
• Stomach cramps
• Fever
• Headache
• Chills

Incubation Period

The incubation period of norovirus, which is the time between exposure to the virus and the onset of symptoms, is typically 24-48 hours.

Treatment and Management

Treatment for norovirus is focused on managing symptoms and preventing dehydration:

• Drinking plenty of fluids, such as water, clear broth, or electrolyte-rich beverages like sports drinks
• Resting and avoiding strenuous activities
• Avoiding solid foods for a few hours after vomiting stops
• Gradually introducing bland foods, such as crackers, toast, and plain rice

Complications

Norovirus can lead to complications, especially in vulnerable populations, such as:

• Dehydration, which can be severe and require hospitalization
• Malnutrition, particularly in young children and older adults

Prevention

To prevent the spread of norovirus:

• Wash your hands frequently with soap and water, especially after using the bathroom or before handling food
• Avoid close contact with someone who has the virus
• Clean and disinfect contaminated surfaces and objects
• Avoid sharing food, drinks, or utensils with someone who has the virus
