I found a syringe in my housing estate . fearing children may pick it up i Picked it up and brought it home and disguarded it in a bin at the back of my house. When I picked it up I was wearing gloves made of wool or some synthetic material. After I took off my gloves I washed my hands with hand soap. Later I put my gloves on and went to my brothers to return his cell phone which he left at my house. I had not washed the gloves after picking up the syringe (theatre was blood in the syringe but I m not sure if there was blood on the outside) I am worried that my brothers phone might be contaminated with HIV, hepatitis or something else and that he or his wife and young family are at risk from. I also left my unwashed gloves on their counter top and after taking off my gloves handled his cell phone and touched things in their home. Also I discarded the syringe into my normal household waste bin , is this ok? Will it pose risk after the waste bin is emptied at the refuse/bin centre? Considering all I wrote, is there any risk of anything? Please advise me what to do.
