The Symptoms of Norovirus

Norovirus is the main trigger of most viral gastroenteritis outbreaks in the world. It can spread from animals or people with the infection. Common ways of contracting the virus include consuming contaminated water, eating contaminated foods, or touching your mouth with a hand that just touched a contaminated surface or a person with the virus. It is hard to get rid of the viruses as they would survive in both cold and hot temperatures. Below are some typical symptoms of norovirus that you need to know.

Nausea and Vomiting

Nausea and vomiting are among the common signs of norovirus infection. It occurs when the body is trying to get rid of the virus. Scientists are still unknown what are the main reasons behind this development. However, excessive vomiting may be dangerous as it leads to a loss of fluids and nutrients. If you keep vomiting for more than 2 days, then it is better to visit your healthcare provider to get medical intervention. Doctors often suggest intravenous drips or oral fluid replacement to prevent dehydration. [1]


In addition to vomiting, diarrhea is another way of eliminating the virus from the system in people with a norovirus infection. It is characterized by watery and loose stools. You also need to have a bowel movement more frequently. In mild cases, diarrhea tends to disappear after a few days without the need for treatments. However, when it persists, dehydration may occur and lead to further complications. If you notice blood in your stool, make sure to visit your doctor as it indicates more serious issues. [2]
