What Is Norovirus and How Long Does It Last?

Norovirus, also known as the winter vomiting bug, is a highly contagious virus that causes unpleasant gastrointestinal symptoms.

Norovirus infections last between 1-3 days. While most people will recover from norovirus infection within a few days, some people may experience more severe symptoms and require medical attention.

Recovery is usually complete within 2-3 days, although some people may take up to 10 days to fully recover. Norovirus is responsible for outbreaks in several areas like hospitals, cruise ships, and daycare centres and is the leading cause of gastroenteritis worldwide.

The most common causes of norovirus infection include contact with an infected person, eating contaminated food or drinking contaminated water. People may experience symptoms like nausea, vomiting, diarrhoea, abdominal pain, fever, headaches, body aches, and a general feeling of fatigue.

Preventative measures to avoid exposure to norovirus, include: washing hands frequently, avoiding contact with infected individuals, and eating only properly cooked food or drinks from sealed containers.

There is no specific treatment or vaccination available for Norovirus infections. The best approach to treatment is a combination of interventions, like enhanced hygiene, improved cleaning and disinfection, education and training of healthcare personnel, and improved food safety practices.
