Yesterday night flying insect got into my ear, I tried to pull out using finger , during this finger nail scratch created bleeding wounds, after pouring olive oil insect died, immediately I went to local ENT clinic in midnight they used scissor to pull insect out but didn't worked but syringe splashed saline water worked. Now my doubt is scissor/surgical tool used to pull insect from my ear might not be sterilized in clinic, It might have contaminated with HCV. Do I need to worry? the time duration between scratch wound created and scissor used in my ear is around 15-20 minutes. will this cover wound surface?
