Norovirus: what is it?  Symptoms and treatment

Norovirus is a highly contagious virus that usually causes acute gastrointestinal illness. Just 10 to 100 noroviruses are enough to cause illness.

Norovirus was previously also called Norwalk-like virus. The virus was first detected in 1972 following a viral gastroenteritis outbreak in Norwalk, Ohio.

An infection due to the large loss of fluid is particularly dangerous for children, older people and people who are generally already in poor health.

How do you become infected with norovirus?

The period from infection to the first symptoms, the incubation period, is 6 to 50 hours.

Infection occurs via the “fecal-oral route”. This means that the viruses are excreted in the stool and absorbed orally. This route of infection is also called smear infection. The main cause of the spread of norovirus is poor hand hygiene. The virus is absorbed through food, drinking water or contact with fecally contaminated objects. However, the virus can also be transmitted via droplet infection, because not only the stool but also the vomit contains the norovirus. When vomiting occurs, small droplets are released into the air and can reach the oral cavity. Transmission occurs exclusively from person to person. The disease is not only highly contagious during the period of symptoms. The sick person is still contagious up to 38 hours after symptoms have subsided.

Norovirus Infection: The Diagnosis

The diagnosis is usually made based on the symptoms.

Norovirus can only be definitively detected by detecting it in the stool. Since the examination is complex, it is only carried out if no other cause of diarrhea and/or vomiting is known or if a larger group of people become ill. This can affect facilities such as kindergartens, schools, retirement homes or hospitals.

Symptoms of norovirus infection

If you have been infected with the norovirus, the symptoms will not appear gradually, but suddenly and with complete well-being.

The disease usually begins with severe diarrhea and bouts of vomiting. However, in isolated cases there may just be vomiting or just diarrhea. Abdominal pain and nausea can also occur. The infection is accompanied by a strong feeling of illness. The gastrointestinal complaints are often accompanied by headaches, body aches and fatigue. A real fever is rare with a norovirus infection. However, a slight increase in temperature may occur. The symptoms subside quite quickly. Significant improvement should occur after 12 to 48 hours. The symptoms are usually very pronounced. However, some infected people only experience mild symptoms or have no symptoms at all.

This is how norovirus infection is treated

There is no medication for norovirus infection. Therefore, the symptoms and the possible consequences are treated. It is important to quickly and effectively compensate for fluid and electrolyte losses caused by diarrhea and vomiting. That’s why: drink a lot. Mineral water is just as suitable as unsweetened herbal teas. You should compensate for the loss of energy by eating enough food. Medications against nausea and vomiting, so-called antiemetics, can help against the accompanying nausea. Maintain bed rest. As already mentioned, the loss of fluids and electrolytes is particularly dangerous for infants, small children, pregnant women, the elderly and weakened people. Therefore, you should definitely consult a doctor if you have these patients. If necessary, infusions may be necessary.
