Influenza, also known as the flu, is a highly contagious respiratory illness caused by influenza viruses. Symptoms of influenza can vary in severity and may include:
- Fever
- Cough
- Sore throat
- Runny or stuffy nose
- Body aches
- Headache
- Chills
- Fatigue
Influenza can range from mild to severe and can lead to serious complications, such as pneumonia, which can be life-threatening, especially for young children, older adults, pregnant women, and people with weakened immune systems.
Treatment for influenza includes getting plenty of rest, staying hydrated, and taking over-the-counter medications to relieve symptoms. Antiviral medications, such as Tamiflu or Relenza, may be prescribed by a healthcare provider to help lessen the severity and duration of symptoms, especially if given within the first 48 hours of symptoms.
Prevention is the best way to protect against influenza. The most effective way to prevent influenza is by getting an annual flu vaccine. Other preventive measures include practicing good hand hygiene, covering your mouth and nose when coughing or sneezing, avoiding close contact with sick people, and staying home when you are sick.
Influenza can be dangerous, especially for people who are at high risk of complications, as mentioned above. In some cases, influenza can lead to hospitalization or even death. It is important to take preventive measures and seek medical attention if you develop severe symptoms or are at high risk of complications.
