Fever is the number one symptom of influenza. Even though fevers can also be caused by many other diseases, influenza is the number one cause. With a fever, your body temperature rises up to an uncomfortable and sometimes even dangerous temperature. It usually takes about 3-4 days for the fever to reduce. Typically, fevers don’t go higher than 41 to 42 °C. From these temperatures, it becomes life-threatening, and you should see a doctor.


Feeling chilly is a symptom of influenza, but is actually caused by fever. Even though your body temperature is high, you might feel cold. It feels as if, even though you’re packed with blankets, you can’t get warm. In reality, your body is way too warm, and wrapping yourself with thick blankets won’t make you feel any better.

Extreme Perspiration

Extreme perspiration is also a symptom that is caused by fever but also indicates that you’re suffering from influenza. It can cause you to feel uncomfortable and gross, but that’s nothing a shower can’t solve. Make sure to hydrate if you suffer from this symptom because extreme perspiration can cause dehydration, which can have life-threatening complications.
