Symptoms of influenza

Usually, the onset of influenza is relatively sudden, with shivering, headache, high fever, muscle and joint pain, low back pain, fatigue and other obvious systemic symptoms. This is because the flu virus flows to the whole body with the circulation of blood.

After the general infection of the virus will remain in the body for several years without the onset of the disease. The virus mutates in the body, making the previous immune system useless.
