What is the Flu?
The flu, also called influenza, is a common illness caused by the influenza virus. Every year, many people get sick with the flu, especially during the colder months. Although most people recover, the flu can sometimes lead to serious problems, especially for young children, older adults, and those with health issues. Understanding the flu helps you stay safe and healthy.
Symptoms of the Flu
Flu symptoms often appear quickly. While some symptoms are mild, others can make you feel very sick. For example, you may notice:
However, not everyone with the flu will have a fever. If you notice these symptoms, it is important to rest and watch for any changes.
Causes and How the Influenza Virus Spreads
The flu is caused by the influenza virus. This virus spreads easily from person to person. For instance, when someone with the flu coughs, sneezes, or talks, tiny droplets go into the air. If you breathe in these droplets, you can get sick. Also, touching a surface with the virus and then touching your mouth, nose, or eyes can spread the flu.
Because the flu spreads quickly, it is common to see more cases in schools, offices, and crowded places. According to the CDC, flu season in the United States usually starts in the fall and peaks in winter.
Diagnosis of the Flu
Doctors often diagnose the flu by looking at your symptoms and asking about recent contact with others who are sick. Sometimes, they may use a quick test by swabbing your nose or throat. These tests can help find out if you have the flu or another illness. Early diagnosis helps you get the right treatment and avoid spreading the virus to others.
Treatment Options
Most people with the flu get better at home with rest and care. However, some may need medicine. Here are common treatment steps:
