Influenza, commonly known as the flu, is a contagious respiratory illness that affects the nose, throat, and lungs. It is especially common during the fall and winter months and can affect people of all ages. Although many people recover within a week or two, the flu can sometimes lead to serious complications, especially in young children, older adults, pregnant women, and people with certain medical conditions.
Understanding the symptoms of influenza and knowing how to prevent its spread can help protect you and your family.
What Are the Symptoms of the Flu?
Flu symptoms often appear suddenly and may include:
- Fever or chills
- Cough and sore throat
- Runny or stuffy nose
- Headaches and body aches
- Extreme tiredness or weakness
- Occasionally, vomiting or diarrhea, especially in children
The flu can feel similar to a common cold, but symptoms are often more intense and develop more quickly. Not everyone with influenza will have a fever.
How Is Influenza Diagnosed?
If you experience flu-like symptoms, visiting a primary care clinic can help you determine the cause of your illness. A healthcare professional may evaluate your symptoms and recommend an influenza swab test to check for the flu virus.
Flu testing can help guide treatment decisions, particularly for people at higher risk of complications. Depending on your symptoms and medical history, your provider may also consider testing for other respiratory illnesses, such as COVID-19.
How Is the Flu Treated?
Most people with the flu can recover at home with proper rest and supportive care. Helpful steps include:
- Getting plenty of rest.
- Drinking enough fluids to prevent dehydration.
- Using appropriate over-the-counter medications to relieve fever and body aches, as advised by a healthcare professional.
- Staying home while sick to avoid spreading the virus to others.
In some cases, a healthcare provider may prescribe antiviral medication. These medications work best when started early, ideally within the first 48 hours after symptoms begin. People at higher risk of complications or with severe or worsening illness should contact a healthcare professional promptly, even if more than 48 hours have passed.
Antibiotics do not treat influenza because the flu is caused by a virus, not bacteria.
How Can You Prevent the Flu?
Taking preventive steps can reduce your risk of getting sick and spreading influenza to others.
- Get your annual flu vaccine. Vaccination is one of the best ways to reduce your risk of influenza and its complications.
- Wash your hands frequently with soap and water.
- Cover your coughs and sneezes with a tissue or your elbow.
- Avoid close contact with sick individuals whenever possible.
- Improve ventilation and avoid touching your eyes, nose, and mouth with unwashed hands.
- Stay home when you are sick and take precautions around people who may be at higher risk.
When Should You Seek Medical Attention?
Contact your healthcare provider if your symptoms are severe, are getting worse, or do not improve as expected. Early medical advice is especially important for young children, older adults, pregnant women, and people with chronic health conditions.
Seek emergency medical care if you experience difficulty breathing, persistent chest pain or pressure, confusion, severe dehydration, or other serious symptoms.
Protect Your Health This Flu Season
Influenza can spread quickly, but recognizing symptoms early and taking preventive measures can make a difference. If you think you may have the flu, a primary care clinic can evaluate your symptoms, provide testing when appropriate, and help determine the best treatment for your needs.
