Any flu infection will not start showing symptoms from the very moment of infection. the virus will take at least a minimum of two to three days to activate fully in the body, spread copiously and multiply before the infected body starts showing any kind of response or symptom for it. In most of the cases, the first symptom of the infection is chills. You either have spells pf chills or you just feel chilly in general. However, it would not be surprising or quite uncommon if your chills were to be accompanied with a fever, in many cases quite a high fever. Many a times. The very first symptom of a flu is the fever which comes and grips you. You will have fever of around thirty nine degree Celsius or approximately a hundred, hundred three degree Fahrenheit. But, this is just the starting, within one or two days, or in certain cases, within a few hours, your fever may scale up severely leading you to be bed ridden for a long time. However, just fever accompanied by chills is not the only thing that you suffer from in these times, there will be agonising crams and severe body and muscular pain. The pain is the most in the legs, especially around the lymph nodes and in the back. However, exposure to sunlight for a few hours daily, in such a situation, may help get relief to some extent because sunlight stalls the infection.

The symptoms of flu with which you will identify it, are:

Severe headache alongwith extreme fatigue, coldness accompanied with fever and aching of the body at the joints and throat especially. Other than these, you may also experience, watering eyes which are at the same time very irritated with getting reddened, reddening of the skin around the areas of your buccal cavity like the nose or the throat etc and some GI problems in kids who have been infected with it. Now, talking of kids, if any child is infected with flu caused by the influenza B virus strain then there are much problems to be handled. In such cases the most prominent symptom would be diarrhoea and severe abdominal pain.

The basic problem in determining flu is in the fact that the symptoms are so very close to that of a common cold. Fever and throat pain and coughing are very clichéd experiences in any common cold. Therefore it is usually difficult to distinguish between the two. However, remember, a flu will always have a sudden onset of high fever which in common cold you will just be feeling feverish at the onset. Also, extreme cases of fatigue accompanied with the high shot fever are very common symptoms of the flu.
