What Is the Stomach Flu and How Do You Catch It?

The term “stomach flu” is oftentimes used to describe an infection of the stomach and intestines, but it’s important to note that it is not related to the regular flu (influenza). Stomach flu, also known as gastroenteritis, is caused by an infection that results in symptoms like vomiting, diarrhea, stomach cramps, and sometimes fever. This infection can be caused by a combination of viruses, bacteria, or parasites, and it can spread quickly from one person to another. Understanding how gastroenteritis spreads is key to preventing illness.

In this blog, we’ll help you understand what the stomach flu is, how it spreads, and what steps you can take to avoid getting infected, keeping you and your family healthy.

What Is the Stomach Flu?

Stomach flu, or gastroenteritis, is an infection or inflammation of the stomach and intestines. The most common symptoms of stomach flu are:

• Nausea
• Vomiting
• Diarrhoea
• Stomach cramps
• Occasionally fever

The main causes of stomach flu are usually viruses, especially norovirus and rotavirus. Sometimes, bacteria or parasites can also cause gastroenteritis. These viruses typically spread quickly, especially in crowded places. Symptoms usually start suddenly and can last anywhere from a few hours to a few days. While it’s generally not life-threatening, the symptoms can be unpleasant and lead to dehydration if not managed properly.

How Do You Catch the Stomach Flu?

The stomach flu is highly contagious, and it spreads primarily in the following ways:

1. Person-to-person contact: The virus spreads when an infected person comes directly in contact with someone else, such as through handshakes or touching contaminated surfaces and then touching the mouth.
2. Contaminated food and water: Eating or drinking food or water that has been contaminated by fecal matter can introduce the virus into the digestive system.
3. Contaminated surfaces: The virus can survive on surfaces like door handles, countertops, or shared items like utensils and glasses, making it easy for the virus to spread.

Stomach flu is especially common in places where people are in close contact, such as schools, hospitals, and even cruise ships. Norovirus, a common cause of stomach flu, is known for its rapid spread in such environments. The best way to avoid getting sick is to practice good hygiene. Frequent hand washing with soap and water and avoiding touching your face are simple yet effective ways to reduce the risk.

Who Is Most at Risk?

While anyone can get the stomach flu, some groups are more vulnerable to severe symptoms. These include:

• Young children: Their immune systems are still developing, and they can become dehydrated more quickly.
• Older adults: Age can weaken the immune system, making them more susceptible to severe symptoms.
• People with weak immune systems: Conditions such as HIV/AIDS, or those undergoing treatments such as chemotherapy, can impact the body’s ability to fight off infections.

For these groups, staying hydrated and seeking early care is particularly important. Dehydration can become a serious problem, particularly for infants, young children, and the elderly. If symptoms are severe, seeking medical care is essential.

Preventing the Stomach Flu

Preventing stomach flu revolves around hygiene and safe practices. Here are some simple tips to help you avoid getting sick:

• Wash your hands thoroughly with soap and water, particularly after using the washroom and before eating.
• Avoid sharing food, drinks, or utensils with others to limit contact with germs.
• Clean and disinfect surfaces on a regular basis, especially in shared spaces like kitchens, bathrooms, and living areas.
• Stay home when sick: If you have stomach flu symptoms, stay home to prevent spreading it to others.
• Practice safe food and water practices: Cook food thoroughly and drink clean water to reduce the risk of foodborne illnesses.

By maintaining good hygiene, you can significantly reduce the chances of catching the stomach flu.

What to Do If You Catch the Stomach Flu

If you start experiencing symptoms of the stomach flu, here’s what you can do:

• Rest and drink plenty of fluids like water, clear soups, or oral rehydration solutions to avoid dehydration.
• Eat bland foods once you feel ready to eat, such as toast, bananas, and rice.
• Avoid sugary, fatty, or spicy foods as they can irritate the stomach and worsen symptoms.

In some cases, medical attention may be needed. Seek care if you experience:

• Severe dehydration (signs include dizziness, dry mouth, dark urine, or light-headedness).
• High fever that doesn't go away.
• Blood in stool or vomiting.
• Symptoms lasting more than a few days.

The Bottom Line

While stomach flu is common and typically resolves within a few days, it’s important to take early steps to prevent and manage the illness. By maintaining good hygiene, staying hydrated, and knowing when to seek medical help, you can recover quickly and avoid serious complications. If you have any doubts or if symptoms worsen, don’t hesitate to consult a healthcare professional.
