Flu and its symptoms
Flu symptoms can last anywhere from a few days to two weeks, with most people feeling better within a week or two.
Symptoms of the flu usually come on suddenly, within 1-4 days after exposure to the virus.
The flu typically causes fever, chills, cough, sore throat, runny or stuffy nose, muscle or body aches, headaches, and fatigue.
You're usually contagious from a day before symptoms develop to up to 5-7 days after becoming sick.
In some cases, the flu can cause severe symptoms, such as pneumonia, bronchitis, and sinus and ear infections.
Certain groups, like older adults, young children, and people with chronic health conditions, are at higher risk for serious flu complications.
Antiviral medications can help shorten the duration and severity of symptoms, especially if started within 48 hours of symptom onset.
Getting plenty of rest, staying hydrated, and using over-the-counter medications can help manage symptoms and support recovery.
The flu can lead to complications, such as dehydration, worsening of underlying chronic conditions, and secondary bacterial infections.
If you experience severe symptoms, such as difficulty breathing, chest pain, or severe headache, seek medical attention immediately.
