The flu, sometimes called influanza, is a contagious disease caused by a virus. The virus is present year round, but is rarely caught. Possible explanations are that the cold air and reduce the immune system that places less ventilated in winter, would promote the transmission of the virus.
It is wrong to believe that you ''catch a cold'' by not being sufficiently clothed triggers flu. On the other hand, if it is true that the cold reduces immunity, is better to keep warm.
The virus moves in quickly (between 24 and 48 hours) and then the infected person has a fever, chills and a feeling of muscle pain. Typically, the fever disappears after 3 or 5 days, but fatigue can last up to two weeks.
In rare cases, influenza can be complicated by attacking the lungs or the nervous system. When the viral infection is accompanied by bacteria, complications such as pneumonia, bronchitis or ear infection can occur. When influenza is complicated or protracted, it is best to consult a doctor.
From one year to another, the virus is changing. It can sometimes be deadly if it is of type A such as the Spanish flu. Type B is less severe and Type C, symptoms, lower, like the common cold.
To prevent flu, you should wash your hands regularly and avoid, when possible, public places during flu. The vaccine is recommended for those most at risk: impaired immune system, a senior, a baby ...
There is no treatment or medication to cure influenza. In a pinch, a drug may relieve symptoms. If the flu is lined with a bacterial infection, the doctor may prescribe an antibiotic.
Do not give medicines to a child without the advice of a doctor. Often, some drugs relieve symptoms but can cause side effects.
