Dear Sir,I am from India and this is regarding an injection I took from a doctor while I was down with fever,I am not sure of the quality of the syringe\needle.I asked him whether it is a new one or not,he confirmed it is a new one,and he uses 2 needles ,one for drawing one for injection.All I remember is he pushing the air bubble out of the syringe with some of the medicine just before injecting,Even if the syringe\needle is a reused one ,used on an hiv person,will this action of pumping out air kill any virus left in the syringe, I know I am highly hypochondriac w.r.t this,but when I browse the net ,I see WHO saying 9pct of new infection in South Asia is through this route,this makes me scared of being unlucky.I am afraid to go for testing again as I am worried on the same again,Is this purely irrational thinking.Should I worry at all.The Doctor is a registered govt doctor ,who provides house calls when ever asked for,He came to my place.Because he came with his kit,I did not check the status of needle.
