The flu is a contagious respiratory illness caused by the influenza virus. It can lead to serious complications, including hospitalization and even death. While most people recover from the flu with rest and over-the-counter medications, some may need medical attention.
Flu symptoms typically start within one to four days after exposure to the virus and can last up to two weeks. Common symptoms include:
- Fever, chills, and cough
- Sore throat and runny or stuffy nose
- Headache, fatigue, and muscle aches
- Diarrhea and vomiting in children under the age of 10
- Loss of appetite and feeling weak
Some people are at higher risk for flu complications, including:
- Pregnant women
- Young children under the age of 5
Seek medical attention if you experience any of the following:
- Persistent or severe symptoms that worsen over time
- Fever above 102°F (39°C)
- Chest pain or difficulty breathing
- Severe headache or confusion
The best way to prevent the flu is through vaccination. The Centers for Disease Control and Prevention (CDC) recommends a yearly flu vaccine for everyone 6 months of age and older.
Preventing the spread of flu requires good hygiene practices, including:
- Avoiding close contact with people who are sick
- Wearing a mask to cover your mouth and nose when coughing or sneezing
- Covering your mouth and nose with a tissue when coughing or sneezing
- Washing your hands frequently with soap and water
You can also treat the flu at home with over-the-counter medications, such as pain relievers and decongestants. However, it’s essential to follow the instructions on the label and consult with a healthcare professional if you have any concerns.
