To the editor: The recently described (1) human immunodeficiency virus type 2 (HIV-2) is distinct but related to HIV-1 by its structure and preferential CD4 tropism and cytopathic effect on these cells. The two viruses share a similar genomic organization but differ significantly in terms of nucleotide and animo-acid identity sequence. The gag and pol genes respectively show only a 56% and 60% nucleotide sequence homology and both less than 60% amino-acid identity (2). The overall nucleotide homology of HIV-1 and HIV-2 is about 42% (2). Serologic studies showed that the gag and pol but not the env proteins
