Hi, I had a nasal endoscopy done in a mega city in China, where they put a thin fiber tube into my nose and all the way to the throat to check a nasal odor condition. After the doctor pulled the tube out, my nose bled, a few big drops initially, then seeped for 10 minutes. They seem to go through a patient every 5 - 10 minutes, and it was a huge government owned hospital. I am quite concerned about infection risks and now regret my decision to get a nasendoscopy when I was there. I went at around 2pm, so there could have been up to 72 patients they saw before me that day? I'd be surprised if they did nothing to clean the tubes, but it didn't seem they'd have enough time to clean it thoroughly between patients. I was not able to see or determine if they had done any cleaning or if there was any blood on the tube before they used it on me. I am a bit paranoid about it, even though the wound healed without any apparent complications. This happened a year ago, and I don't feel any problems, except I seem to be more susceptible to the flu and cold viruses this year than years past? Could you advise on the risk of infection of HIV or other diseases? for example, I heard hepatitis C stays alive for a long time and is hard to kill? What was the risk if they had done simple alcohol wiping or no cleaning at all? What other serious diseases that are without symptoms after a year could be transmitted this way? thanks!
