Without antibiotics, you may be contagious for two or three weeks; most people who take them, however, are no longer contagious 24 hours after the start of treatment. Other people also experience relief from the symptoms of strep once they've started taking antibiotics.

Evidently the flu doesnt need fever to be contagious in the beginning.
