The report HIV/AIDS Prevention in Vietnam from 2001 summarizes work on interventions geared toward sex workers and their clients that raise awareness in a high-risk area of Vietnam's Mekong Delta, the dusty two-lane road that is National Highway 80. 

Working closely with the National AIDS Standing Bureau and provincial AIDS authorities, FHI aims to use public awareness messages to reduce the risk of HIV among vulnerable populations here. "The condom tunnel is having a major impact, not only on the highway but over a broader area," says Thomas Kane, PhD, FHI's country director in Vietnam.
