I had gotten Croup as a teen and I now get it every year in the fall im 24, is it still contagious when I have it? And will it ever go away?
At least a week: Most viruses follow the same basic pattern. Viral numbers expand exponentially until our immune systems can generate an effective response (fever is the first attempt). Antibody response to viruses takes 3-5 days and peak infectivity is usually the first week. We continue to shed virus for 1-2 weeks after. Respiratory viruses are spread by droplets which can travel up to 4 feet through the air. ...Read more
