Norovirus are a typical cause of non-bacterial episodes of abdomen problems. Gastroenteritis, often termed as "winter vomiting sickness or “stomach flu,” is a typical sickness. It should not be puzzled with influenza, which is known as the “flu.”
Where does the virus come from and how is it spread?
The virus is easily circulated. The main source of the virus is poops (feces) and throw up from attacked persons. The virus is most often propagated from person-to-person on filthy hands. The Virus can also be propagate by meals, water or ice that has been prepared by a sick individual. Throwing up may propagate the virus through the air. The malware can survive on surfaces such as counter tops or drain faucets for a long period. Episodes of Norovirus have been caused by meals (including shellfish) and water attacked with the malware.
What are the symptoms?
The main signs are rapid start of throwing up and nausea or vomiting (common in the young), diarrhoea (more typical in adults), stomach pain, muscle pain, exhaustion, frustration and low grade high temperature. Symptoms generally last between 24 and 48 hours. Liquid loss caused by throwing up and diarrhoea can cause serious problems, especially for the seniors and the very younger.
Is there a treatment available?
Drinking lots of clear fluids while ill is important. If diarrhea or vomiting lasts more than two to three days, see a doctor. If three or more persons are ill at the same time, this should be reported to your local public health unit.
How can this illness be prevented?
There is no vaccine or medicine that can prevent Norwalk virus infection. Also there are different types of Norwalk-like viruses, so people who have had it once can get the illness again.
Hand washing is the key to reducing person-to-person spread of Norwalk virus. A proper hand wash requires warm running water, soap and rubbing hands together for about 30 seconds.
Stay home if you're ill and avoid going to work until 48 hours after symptoms disappear (especially if you are a food handler or caregiver). Even after they are well, people can carry the virus in their stool for a few days, so careful hand washing should continue.
Frequent disinfection with a dilute bleach solution (at least one part household bleach to 50 parts water) of high traffic areas and commonly touched items including:
