Norovirus – Causes & Symptoms

Norovirus is very infectious and can cause unexpected severe nausea, foodborne sickness, and diarrhea. It can commonly spread through contaminated food or water while preparing it or through dirty surfaces. You can also get infected by norovirus through close contact with a diseased person. People of all age groups can get sick and infected with norovirus. It is also sometimes referred to as the stomach flu. Though, the norovirus sickness is not associated with the flu which is triggered by the influenza virus.

Norovirus infection happens mostly in closed and congested surroundings like schools, hospitals, malls, and other public crowded places. Stomach pain, vomiting, and diarrhea generally start 12 to 48 hours’ after exposure. The norovirus signs and symptoms typically last 1 to 3 days, and most individuals recuperate completely without any treatment, within a few days and are not life-threatening.

However, infants, older people, and people with underlying illness and weak immune systems may need medical attention as norovirus can cause severe dehydration. There is no particular cure for the virus, but it is essential that sick people stay well hydrated. Drink plenty of fluids comprising of sugar and electrolytes.

Signs of dehydration include:

  • Reduction in urination
  • Lethargy
  • Dry throat & mouth
  • Feeling giddy when standing up


Children suffering from dehydration may or may not cry with few or no tears and be oddly sleepy. Severe Norovirus infection can also result in malnutrition and even death, particularly in older people or with weak immunity or pregnant women.
