<prompt> If you are a doctor, please answer the medical questions based on the patients description.HelloDear doctor, is it possible to infect someone in such a situation: I squeezed somebodys pimple and insignificant amount of blood certainly got under my nail. Then in few minutes I was biting my nails and picking in nose. I didnt wash my hands previously. Is it dengerous?  <response>: What you have described is an unhygienic practice. While it is unlikely that you may have infected yourself, you should certainly avoid such practices of other reasons:1. Biting nails is aesthetically unpleasant;2. Nose picking can cause epistaxis bleeding from the nose.3. Remote possibility of infection. Handwashing after touching a potentially infected site is a very good practice and should be followed.
