Besides, better estimation of populations at risk (i.e., those currently injecting drugs, or sex partners of IDUs and populations coming to be at risk), and a better understanding of the dynamics of drug utilization and social association of drug use are all necessary for targeting interventions efficiently.

Populations in Bangladesh are moving across land and sea borders in increasing numbers. International trade supports this growth in population mobility, international border between India and Bangladesh, more than 500 trucks come daily. Also occurring in Bangladesh are high levels of maritime trade, and seamen on fishing vessels travel widely in the region, enabling the transmission of HIV to populations in areas where the virus was previously unfamiliar.

Crossing land or sea borders often requires overnight stays, leaving the individual with idle time and opportunities to visit drinking and gambling establishments and brothels. HIV surveillance data for female sex workers, male STD clinic patients and young males at two sea ports – Cittagong & Mongla --show a clustering of high prevalence sites.
