What is Norovirus?
According to the Center for Disease Control and Prevention, the Norovirus is contagious and causes vomiting and diarrhea.
It usually takes 12 to 48 hours to develop symptoms of the virus. Symptoms include: diarrhea, vomiting, stomach pain, fever, headache and body aches.
How does Norovirus spread?
There are several ways the Norovirus can spread, according to the CDC.
You could become ill with the virus if you have direct contact with someone who has it. This includes sharing food or utensils, eating food handled by them, or caring for them.
If you eat anything that is contaminated with Norovirus, you could get sick.
Anyone suffering from Norovirus can spread the virus for two weeks or longer after feeling better.
What makes up a Norovirus outbreak?
The New Jersey Health Department explained that the way ‘outbreak’ is defined depends on where it’s being reported.
For example, in a school, an outbreak is defined as ‘an occurrence of two or more similar illnesses resulting from a common exposure that is either suspected or laboratory-confirmed to be caused by norovirus.’
For long-term care facilities, an outbreak is defined as ‘one laboratory-confirmed positive case of norovirus along with other cases of gastrointestinal illness in the facility,’ or ‘A sudden increase over the normal background rate of acute gastrointestinal illness, with or without lab confirmation.’
