Worried about bro's "flu"?

There's nothing unusual about his symptoms - they are typical of a common cold. The severity of cold symptoms varies substantially from person to person, and many times people also have bacterial infection at the same time. Colds usually take 10-14 days to clear up completely. The only thing to watch out for right now is a fever of 103 F or higher and a stiff neck - these things indicate more serious complications and people should seek immediate medical attention.
