Yes, I had RSV 2 Christmas's ago. There was nothing they could do for it, I just had to let it run it's course. Just be very diligent with Nebs and treatments. The only thing I was put on for it was Nebulized Albuterol instead of the puffer that I usually do. I was doing treatments 4 times a day which consisted of the vest for 30 minutes each time, or longer depending on how much I could take. Really push the liquids.... Hope he or she feels better soon.....
