The flu is one of the most common illnesses faced by people during the cold season. The flu, which is short for influenza, is a contagious respiratory illness. It is caused by the influenza virus, and it can cause mild to severe symptoms.

Some people are more likely to be hospitalized if they are infected with the flu virus. In this article, we will discuss who is most likely to be hospitalized because of the flu virus.

What is Influenza?

Influenza, or flu, is a contagious respiratory illness that is common during the winter months. It is caused by influenza viruses that infect the nose, throat, and sometimes the lungs.

People of any age can get the flu, but it is especially dangerous for young children, older adults, and individuals with weakened immune systems. There are three types of influenza viruses: A, B, and C. Influenza A and B are the most common types that cause flu epidemics.

What are the Symptoms of Flu?

The symptoms of flu can range from mild to severe. Common symptoms of the flu include:.

Fever
Cough
Sore throat
Headache
Muscle aches
Fatigue
Chills
Runny or stuffy nose

How is Flu Spread?

The flu is highly contagious and can spread from person to person through respiratory droplets when someone talks, coughs, or sneezes. The flu virus can also live on surfaces such as doorknobs and tables for up to 24 hours.

You can get infected with the flu virus by touching a surface contaminated with the virus and then touching your mouth, nose, or eyes.

Who is Most Likely to be Hospitalized for Flu?

Although anyone can get the flu, some groups are more likely to be hospitalized for the flu. These groups include:.

Adults over the age of 65
Pregnant women and women who have recently given birth
People with chronic medical conditions, such as asthma, diabetes, and heart disease
People with weakened immune systems, such as those undergoing chemotherapy or living with HIV

Why Are These Groups More Likely to be Hospitalized?

There are many reasons why these groups are more likely to be hospitalized for the flu. Children under the age of 5 have not yet developed a strong immune system, which makes them more vulnerable to the flu.

Adults over the age of 65 may have weakened immune systems, making it harder for them to fight off the flu virus. Pregnant women are also more vulnerable to the flu because their immune systems are suppressed during pregnancy. Additionally, the flu can have serious complications for people with chronic medical conditions and weakened immune systems.

What Are the Complications of Flu?

Complications of the flu can include:.

Pneumonia
Bronchitis
Sinus infections
Ear infections
Dehydration
Worsening of chronic medical conditions, such as asthma and heart disease

It is recommended for everyone over the age of 6 months, especially those who are at higher risk for complications from the flu. Additionally, you can protect yourself from the flu by:.

Washing your hands frequently with soap and water
Covering your mouth and nose when you cough or sneeze
Avoiding close contact with people who are sick
Cleaning and disinfecting surfaces that may be contaminated with the flu virus
