How to Prevent Stomach Flu

stomach flu, also known as Norovirus Infection, a contagious disease that affects people regardless of age. The infectious disease usually spreads in areas where people have been in close contact for long periods of time, such as cruise ships or prisons.

Because there are many different types of norovirus, it is possible to contract the virus multiple times in a lifetime. Preventing this very spreadable disease can be challenging, but there are steps you can take to try and prevent it.

This article will explain how stomach flu spreads, different prevention strategies, how to treat it at home, and when to see a doctor.

What is it?

Norovirus or stomach flu is an infectious disease. Although it’s commonly called the stomach flu, it’s not related to the seasonal flu virus. Its symptoms are primarily gastrointestinal (related to the digestive system) and include:

  • diarrhea
  • nausea and vomiting
  • stomach pain or cramping
  • fever
  • body pain
  • headache

These symptoms occur because the virus causes inflammation of the gastrointestinal tract. In some people, severe diarrhea and vomiting can lead to dehydration (loss of body fluids).

Symptoms appear soon after exposure, usually within 12 to 48 hours. It can affect anyone, but people who work with children or have close contact with other infected people are more likely to contract the virus.

Older adults and people with underlying medical conditions or weakened immune systems may experience more severe symptoms than others.

Is it contagious?

Norovirus is highly contagious. You get stomach flu by ingesting infected feces or vomit particles. Even tiny infected substances can spread disease. Often, people come into contact with infected particles through contaminated food or water. This is called the fecal-oral route of transmission.

This could be caused by:

  • People preparing or cooking food are not washing their hands properly before doing so.
  • Food preparation areas are contaminated with infectious particles.
  • Food is grown or washed with contaminated water.

Being in close contact with an infected person and sharing cups, utensils or food with them can also cause you to get stomach flu.
