I went to the er and the doctor said i have a viral how long do viral last cause i feel really bad they said up to two week or more is that true?

Viral syndrome: Yes, some viral illnesses can last two weeks or longer while others are of shorter duration. Unfortunately, there typically aren't any treatments for most, especially if you're referring to the common cold or upper respiratory illness. Other viruses such as hepatitis, HIV & hpv can last a lifetime w/some treatment now available. Still prevention via vaccination & risk reduction is best if possible.
