The terms “cold” and “flu” are often used synonymously in the vernacular. However, anyone who has been infected with real influenza (viral flu) can quickly notice certain signs. The course of the virus infection shows clear differences to a simple cold. Typical of the severe form of the flu-like infection is, for example, that it suddenly attacks the sick person with severe complaints.
How to recognize a severe flu
There are usually 24 to 48 hours between infection and the onset of the disease. Then all of a sudden you feel weak and sick. In addition, there is often a strong sensation of cold, chills, sweating as well as headaches and aches and pains. Other typical symptoms can include a dry cough with a sore throat, a runny nose, watery eyes and nausea. Some sufferers lose their appetite, become shy of light or are sensitive to noises.
This is how the body defends itself against the viruses
As a defense reaction to the pathogens, the temperature in the body rises: the patient quickly gets a fever of over 40 ° C. In any case, if you have the flu, see a doctor immediately as soon as you see the first signs. With the appropriate medication, this can alleviate the symptoms and shorten the course of the disease.
