Table 3 Validation of putative superinfection cases

From: Superinfection with drug-resistant HIV is rare and does not contribute substantially to therapy failure in a large European cohort

  1. Results of the validation of 14 cases of putative superinfection and 4 controls. Samples where thawed, amplified and pol and env regions where sequenced as described in the Methods. Full circles indicate confirmed superinfection cases. Notes: 1the sample before the superinfection event was unavailable, an alternative was used; 2neither of the original samples were available and two alternatives were used. An asterisk (*) indicates that subtype could not be determined uniquely. Abbreviations: IVDU - intravenous drug users; HET - heterosexuals; MSM - men having sex with men; VERT - vertical transmission; NA - unknown; F - Female; M - Male.
