An HIV-1 infected man who experienced rapid disease progression and poor response to therapy after starting a new sexual relationship with an infected partner is known as the 'Ottawa superinfection case'. Subsequent analysis of viral sequences of protease, reverse transcriptase, Gag p17, and Env V3 provided no evidence for the acquisition of genetically divergent viruses before disease progression or drug resistance during virological failure of combination therapy. Whether HIV-1 superinfection contributes to disease progression or the spread of drug-resistant HIV-1 remains unknown.
