This week I have some very minor signs of a cold. A test came back showing it to be RSV - a respiratory virus similar to the common cold but at higher risk of causing pneumonia. The doctors concluded the safest thing to do is treat it now as a prevention so is doesn't spread to my lungs. The treatment is called Ribavarin treatment. It's done in the hospital 3 times a day, 2 hours each time. They put an enclosed clear plastic square "bubble" over the bed and run ventilator that humidifies the medicine and I wear a mask to breath it in. Not sure how many days I'll be here, but sounds like at least 5 days or so. I started last night.
