I just flew in from Washington State many people with cold virus and flu ..now I am very sick..what to do and what virus am I dealing with?
You'll need your doctor diagnose exactly what is causing your symptoms.
Not only do cold and flu have some symptoms in common, but there are other conditions that can be mistaken for cold & flu. You can try this respiratory illness assessment to help give you an idea of what may be bothering you -- but you will need to see your doctor for an official diagnosis.
Keep in mind that if you have an infection of some kind, it may be bacterial and not viral.
Good luck and please come back if you have more questions!
