In brief: URI contagious

If you have a viral upper respiratory infection, two - three days.
If you have a bacterial respiratory infection, which may follow the viral uri, generally this is not contagious. Bacterial infections generally follow the insult from the virus. Antibiotics will shorten the duration of a bacterial infection. Prednisone speeds up recovery quickest, but should be used with caution.
