I am confused. If you have been exposed to a risk for Hep C and HIV, and co-infection can affect the results of the tests, how are you supposed to know if you are infected with these diseases? Should you go ahead and have a HIV duo test at 28 days, or is it a waste of time, given that if you are co-infected the results are not reliable?
How common is co-infection, is it something commonplace amongst HIV + people or is it rare???
