What is Influenza?
Influenza, commonly known as the flu, is a viral infection affecting the respiratory system. It is generally seen in autumn and winter months, but can also be effective in other periods of the year. The most common types are Influenza A and B; as these types change annually, different virus subtypes are encountered each season. This means our immune system is constantly exposed to new threats. Influenza is transmitted through the respiratory tract; it spreads particularly through droplets released into the air during coughing, sneezing, and speaking. The risk of transmission also increases when touching surfaces contaminated with the virus and then touching the mouth, nose, or eyes with hands.

Symptoms and Course
Influenza typically presents with a sudden onset of high fever. Body aches, headache, dry cough, sore throat, and extreme fatigue are common symptoms. Some individuals may also experience loss of appetite, nausea, and rarely vomiting. Influenza can be much more severe in groups with weakened immune systems, such as children and the elderly. Complications like pneumonia, bronchitis, and sinusitis can develop, especially in individuals with chronic diseases. Therefore, it is important for individuals in risk groups to seek medical attention without delay when disease symptoms begin. Although the flu and the common cold are often confused, the flu is generally more severe and lasts longer.
Prevention and Treatment
The most effective way to protect against the influenza virus is to get the flu vaccine annually. The World Health Organization particularly recommends vaccination for risk groups. Vaccines are prepared according to the virus types expected to circulate in that season. Besides vaccination, frequent hand washing, avoiding crowded and enclosed environments, regular sleep, adequate fluid intake, and a balanced diet also play a protective role by strengthening immunity. After the disease begins, treatment generally focuses on alleviating symptoms. Antiviral medications, when used in the early stages (within the first 48 hours), can reduce symptoms and shorten the duration of the illness. However, these medications must be used with a doctor's prescription. Antibiotics are ineffective against the flu, which is a viral infection; they should only be used under medical supervision if a secondary bacterial infection develops. Resting, drinking plenty of water, and consuming foods rich in vitamin C contribute to the recovery process.
