Influenza, or the flu, is common a respiratory viral infection. Each year there are about 10% – 15% cases of influenza, affecting 250.000 – 500.000 people. The flu often begins suddenly and goes away after 7 to 10 days. The flu can be dangerous to some people, especially if they are infected with more advance types of flu virus.
Influenza often begins suddenly, lasts for 7 to 10 days, and goes away for most people. Most people recover completely. However, the elderly, the very young, and those with weak immune system can have a more severe course and even die from complications.
Influenza is extremely common and can affect patients at any age. An adult may get influenza at least 2-3 times/year and 6-7 times/year for children. The flu is most common in the fall – the flu season. It can be managed by reducing your risk factors. Please discuss with your doctor for further information.

In most cases, the flu can be self-diagnosed. You might recognize it from its symptoms, such as fever and fatigue. There is a test called the Flu Test (or Rapid Flu Test and Influenza Antigen Test) designed to identify influenza virus.
This test is often used in the flu season to control the spreading. The Flu Test may involve taking a sample of liquid from a runny nose or using a blood sample. The doctor may also order a chest x-ray to check for pneumonia – a complication of influenza.
Testing is recommended in particular for people who are hospitalized, have weakened immune systems, or are otherwise at an increased risk of serious complications.
If influenza has already been identified in the community, a health practitioner may order a flu test to confirm the diagnosis and validate possible antiviral treatment.
Most people who get the flu can treat themselves at home and often don’t need to see a doctor. The best treatment is rest. Most people misunderstand that ani-biotics can cure the flu. However, taking anti-biotic will not make the flu any better, but also will increase your risk of building anti-biotic resistance.
If the symptoms make you feel uncomfortable, you can talk to your doctor about taking medication to treat specific symptoms. You can find some of these medication over-the-counter. Non-aspirin medicines, such as acetaminophen and ibuprofen, are used for pain relief; cough syrups to control the sore throat and coughing; and decongestants for stuffy nose.
