Common symptoms, self-isolation and treatment information, and when to seek medical help
Symptoms of influenza include:
- Fever
- Cough
- Sore throat
- Body aches
- Fatigue
- Headache
- Chills
- Diarrhea, nausea, or vomiting (sometimes)
Most patients experience a moderate respiratory illness and recover completely without medical intervention
If you have the flu...
- Self-isolate: This means you should avoid close contact with other people until 24 hours after your fever has resolved and your body temperature has remained normal without fever-reducing drugs such as acetaminophen and ibuprofen. Self-isolation keeps you from spreading the illness to others.
- Take fever-reducing drugs such as acetaminophen or ibuprofen. You won't need prescription antiviral drugs such as Tamiflu or Relenza unless you are severely ill or have a medical condition that puts you at risk for serious complications from the flu.
Seek medical help if your symptoms become worse or are serious.
