ABSTRACT

In many areas, the introduction of HIV-1 into the local population of injecting drug users (IDUs) was followed by extremely rapid dissemination within this group. Rapid HIV-1 spread has occurred both in industrialized and developing countries, and in very large cities such as New York (Des Jarlais et al., 1989), moderate-sized cities such as Edinburgh (Robertson et al., 1986) and in semirural areas such as the state of Manipur, India (Naik et al., 1991) (also see: Des Jarlais et al., 1992; Friedman and Des Jarlais, 1991).
