What is Flu?
Flu, also known as influenza, is an infectious respiratory condition. It occurs due to viruses that affect the throat, nose, and even the lungs. Although it can sometimes be mistaken for cold, the flu is relatively different. Besides, the symptom of flu can vary slightly from those of cold and can last for an extended period.
Flu can subside or heal on its own in some people. But in other cases, it can result in life-threatening complications. Everyone is at risk of developing the condition. Hence, the best method of preventing it is through annual flu vaccination.
Most healthy people recover completely within a few days of infection, although complications such as pneumonia and mortality occur in some high-risk populations. Young children, the elderly, the immunocompromised, and pregnant women are among these categories.
