The Center for Disease Control and Prevention reports that the amount of norovirus cases is the highest they've seen in the past year.

Norovirus is a highly contagious stomach bug that spreads very quickly and easily.

The virus can spread from hands, surfaces, food and water.

Doctors say handwashing is key to avoiding norovirus.

They also recommend you rinse your fruits and vegetables and cook shellfish thoroughly.

Of course, if you are not feeling well, the CDC recommends staying home for at least two days after symptoms stop.

The CDC says cases have been trending upwards this winter – especially in the Northeast with a 15.059 % positivity rate reported in the region on Feb. 25, according to a CDC surveillance report. 

The positive tests this year exceed last year's peak.
