The influenza virus, commonly known as the flu, is a contagious respiratory illness that causes mild to severe illness, and at times can lead to death. Characterized by fever, cough, sore throat, and other symptoms, the flu can spread from person to person through respiratory droplets produced when an infected person coughs or sneezes. Understanding the Flu Virus The influenza virus is categorized into three main types: A, B, and C. Influenza A and B viruses are responsible for the annual flu epidemics, while influenza C viruses typically cause mild, illness similar to the common cold. Symptoms of the Flu The flu typically begins with a sudden onset of symptoms, including:

• Fever
• Cough
• Sore throat
• Runny or stuffy nose
• Muscle or body aches
• Headaches
• Fatigue (tiredness)
• Some people may also have vomiting and diarrhea, though this is more common in children than adults.

Complications of the Flu While the flu is usually self-limiting, it can lead to serious complications, especially in young children, older adults, and people with chronic health conditions. These complications include:

• Pneumonia
• Bronchitis
• Ear infections
• Sinusitis
• Dehydration
• Worsening of chronic health conditions

Prevention and Control of the Flu The most effective way to prevent the flu is to get an annual influenza vaccine. The vaccine is recommended for everyone 6 months of age and older, but it is especially important for people at high risk of flu complications. Other measures to prevent and control the flu include:

• Frequent handwashing with soap and water or an alcohol-based hand sanitizer
• Covering your mouth and nose when coughing or sneezing
• Avoiding close contact with sick people
• Staying home when you are sick

Treatment of the Flu Most people with the flu can recover at home without medical care. Treatment typically focuses on relieving symptoms and preventing complications. This may include:

• Rest
• Plenty of fluids
• Over-the-counter pain relievers
• Fever reducers

In some cases, antiviral medications may be prescribed to help shorten the duration of the illness and reduce the risk of complications. When to Seek Medical Care If you experience any of the following, seek medical care immediately:

• Difficulty breathing or shortness of breath
• Bluish lips or face
• Persistent vomiting or diarrhea
• Fever in a child under 2 months old
• Fever of 103°F (39.4°C) or higher in an older child or adult

Recovery from the Flu Most people who get the flu recover within a week or two. However, it may take several weeks for your energy to return completely.
