🧬 What Is Influenza Flu?
Influenza, commonly known as the flu, is a contagious respiratory illness caused by certain viruses. It affects the nose, throat, and sometimes the lungs. The flu spreads mostly through droplets from coughing, sneezing, or talking. The influenza flu virus symptoms often appear suddenly and may last from a few days to two weeks.
There are mainly four types of influenza viruses – A, B, C, and D.
- Influenza A & B are responsible for the majority of flu cases in the U.S.
- Influenza flu type B generally causes milder illness but still affects many people every year.
- Influenza C causes mild symptoms and is not a major concern.
- Influenza D mostly affects animals, not humans.
📅 Influenza Flu Season in USA
The influenza flu season in USA usually starts in October and peaks between December and February, though cases may continue until May. Doctors recommend getting the influenza flu vaccine before the season begins. During the peak months, hospitals often report a noticeable influenza flu outbreak in multiple states, especially in colder regions.
Early Influenza Flu Virus Symptoms to Watch
The influenza flu virus symptoms appear within 1 to 4 days after exposure. They come suddenly and may include:
| Common Symptoms | Other Possible Symptoms |
| High fever | Headache & eye pain |
| Dry cough | Nausea or vomiting |
| Sore throat | Shortness of breath |
| Body pain | Chest discomfort |
| Fatigue | Appetite loss |
Many patients report severe body aches and tiredness, which makes daily tasks difficult. When influenza virus B symptoms occur, recovery may take longer in children and elderly individuals.
Difference Between Influenza and Common Cold
People often confuse the common cold with influenza. But both infections are different:
| Feature | Influenza | Common Cold |
| Onset | Sudden | Gradual |
| Fever | High | Mild or none |
| Body Pain | Severe | Less common |
| Fatigue | Strong | Mild |
| Risk of Complications | Higher | Lower |
Understanding influenza flu virus symptoms early helps prevent serious illness. Cold symptoms are mild, while flu symptoms may require medical attention.

Some people are at higher risk during an influenza flu outbreak, including:
- Adults over 65 years

For these individuals, recognizing influenza virus B symptoms quickly is important for safety.

- Persistent cough

Children and seniors may face more complications from influenza flu type b infections. Regular hydration, rest, and medical care ensure smooth recovery.
