If it progresses to bronchitis you probably do need antibiotics, because that is the sign of a bacterial infection in TOP of whatever virus set it all in motion...

Now I KNOW I don't need to say this but I have seen people on their bikes smoking, so I will say it anyway! IF anyone smokes, and has had bronchitis repeatedly, it is a sign that they are heading into emphysema which is a chronic lifelong debilitating disease. Please don't smoke!

And I second the request that you work out in your own space rather than around others who might catch what you have!

I love hand sanitizer - especially at the gym!
