Norovirus, sometimes referred to as the “winter vomiting bug”, is a very contagious virus. It is the most common cause of gastroenteritis (stomach flu) in the world and causes diarrhea, vomiting, and stomach pain. Norovirus is commonly spread through contact with an infected person, consuming contaminated food or water, or touching contaminated surfaces. It can also be spread through the air when an infected person vomits.
Transmission
Norovirus is highly contagious and is spread by direct contact with an infected person or through contaminated food or water. It can also be spread through contact with contaminated surfaces, such as countertops or doorknobs. In addition, the virus can be spread through the air when an infected person vomits.
Symptoms
Norovirus symptoms usually begin to appear within 12 to 48 hours after exposure. The most common symptoms of norovirus are diarrhea, vomiting, nausea, stomach cramps, and low-grade fever. Other symptoms may include fatigue, headache, body aches, and loss of appetite. Symptoms usually last for 1 to 3 days.
Treatment
There is no specific treatment for norovirus and most people will recover without medical intervention. However, it is important to drink plenty of fluids to prevent dehydration. Over-the-counter medications may be used to treat the symptoms of norovirus, such as anti-diarrheal medications and pain relievers. If symptoms persist, it is important to seek medical attention.
