Influenza, also known as the flu, is a highly contagious respiratory illness caused by influenza viruses. The flu primarily affects the respiratory system, including the nose, throat, and lungs.
Symptoms of influenza typically include:
Fever or feeling feverish/chills
Cough
Sore throat
Runny or stuffy nose
Muscle or body aches
Headaches
Fatigue (tiredness)
Sometimes vomiting and diarrhea (more common in children than adults)
The severity of flu symptoms can vary from mild to severe, and in some cases, can lead to complications such as pneumonia or bronchitis, especially in high-risk groups such as young children, elderly people, pregnant women, and those with underlying medical conditions.
To prevent the spread of influenza, it is recommended to practice good hygiene, such as washing hands frequently, covering your mouth and nose when coughing or sneezing, avoiding close contact with sick people, and staying home if you are sick. Vaccination is also an effective way to prevent the flu and reduce its severity if contracted
