Presence of multiple non-B subtypes and divergent subtype B strains of HIV-1 in individuals infected after overseas deployment

Abstract

In the group of HIV-1-infected individuals that we studied and who were deployed overseas, 63.4% were infected with non-B strains. In addition, the subtype A, B and C viruses in this population were very heterogeneous. Due to the routine occurrence of international travel and deployment, the predominance of subtype B HIV-1 viruses may change in European countries. However, the possible implications on the dynamics of the HIV-1 epidemic needs further follow-up.
