Okay I went with one of my relatives to a hospital where many patients were admitted due to ongoing viral fever season. One of the patient was very sick. Nurse came to us first, and started the new drip in between she had to go to the patient i described. She changed his drip as well without gloves. Then she came to us and started giving injection through butterfly syringe. She also changed the bottle and inserted a new needle for air into that. My concern is that what if there was some blood stain on her hand and with the same hand she did the entire above process. I also tried to look for some blood stains on her hand but couldn't find any. The whole process took place very quickly. Is there any risk of hiv to my relative. We are very concerned.
