Influenza, commonly known as the flu, is a viral infection that affects the respiratory system. While most cases of the flu are caused by the influenza A or B viruses, there are other strains of the virus that can cause the illness. In some cases, the cause of the flu may be unknown, leading to a diagnosis of influenza due to an unidentified influenza virus with pneumonia.
Influenza viruses are highly contagious and can be spread through the air when an infected person coughs or sneezes. The virus can also be spread by touching a surface contaminated with the virus and then touching the mouth, nose, or eyes. In some cases, the cause of the flu may be unknown, making it difficult to determine the specific strain of the virus responsible for the illness.
The symptoms of the flu can range from mild to severe and may include fever, cough, sore throat, runny or stuffy nose, body aches, headache, chills, and fatigue. In some cases, the flu can lead to complications such as pneumonia, which can cause severe respiratory symptoms and may require hospitalization.
The treatment for the flu typically involves rest, hydration, and over-the-counter medications to relieve symptoms such as fever and pain. In some cases, antiviral medications may be prescribed to help reduce the severity and duration of the illness. If pneumonia develops as a complication of the flu, treatment may involve antibiotics, oxygen therapy, and other supportive measures to help manage respiratory symptoms.
