The severity of symptoms is related to the severity of the fever. Fever and systemic symptoms typically last 3 days, occasionally up to 4-8 days, and gradually diminish; however, cough and malaise may persist for more than 2 weeks. Second fever spikes are rare. The physical findings are summarised in table 3. Full recovery may take 1-2 weeks, or longer, especially in the elderly. Table 3. Physical findings of uncomplicated influenza. Fever: rapidly peaking at 38-40Â°C (up to 41Â°C, especially in children), typically lasting 3 days (up to 4-8 days), gradually diminishing; second fever spikes are rare.
Types of flu - A can affect humans as well as animals, B is so far only present in humans, type C is a mild version of the flu which also affects both, and then there's bird flu, which is the one we don't want - thats H5N1. It takes about 7 up to 14 days to get over the main illness. There's still considerable weakness that can last for a few weeks after. Most people don't feel 100% until about 3-5 weeks have passed. Rest is the most important thing you can do. Taking vitamin C, eating soups and easy foods, eating fruits all helps. Keep warm - even a small chill can lengthen the time of recovery. And do not do any physical exercise - and especially do not overexert yourself.
