Abstract__ HIV-1 epidemic in India is largely driven by subtype C but other subtypes or recombinants have also been reported from several states of India. This is mainly due to the co-circulation of other genetic subtypes that potentially can recombine to generate recombinant mosaic genomes. In this study we report detail genetic characterization of HIV-1 envelope sequences from North India Delhi and neighboring regions . Six of .
