The flu, otherwise called influenza, is a viral infection that affects your nose, throat, and lungs. It is often confused with a common cold. However, it is a distinct condition that is more serious than a common cold.
Influenza viruses changing constantly, with new strains coming up regularly. If you have suffered from influenza earlier, your body many have already made antibodies to fight that specific virus strain. If future influenza viruses are similar to those you have encountered in the past (either by having had the disease or by getting vaccinated), those antibodies can prevent infection or reduce its severity. However, antibody levels may decline over time.

As many people die from the flu every year, it is important to treat the infection and prevent complications from developing. If serious complications occur, they can be treated with medical care.
Complications of the flu are quite rare. However, some of them, like pneumonia, can be deadly, and so it is best to diagnose and treat the complications, if you have any, immediately. Some of them are:

The flu is an infection that usually resolves on its own. Taking rest, drinking plenty of fluids, and eating healthy foods is extremely crucial during the infection.
You may pass or receive the flu if you touch your nose, eyes, or mouth after touching a contaminated object. You can also get it if an affected person near you sneezes or coughs.
2. Is there a vaccination for bird flu?
No, there is no vaccination for bird flu. Influenza vaccines do not provide protection from avian flu.
3. What are the causes of the flu?
Influenza is caused by the flu virus. It can spread easily by contact and air. If you touch a contaminated surface and bring your hand to your nose, eyes, or mouth, you may acquire the disease. The same happens when you breathe in contaminated air, for instance, when someone sneezes next to you and you breathe in the contaminated air.
