Many countries around the world have invested heavily in the past decade in collecting information about the human immunodefi ciency virus (HIV) and the behaviour that spreads it. The World Health Organization (WHO), the Joint United Nations Programme on HIV/AIDS (UNAIDS) and partner organizations have supported this investment and have developed guidelines detailing the principles of what is now known as second-generation HIV surveillance. Second-generation surveillance includes biological surveillance of HIV and other sexually transmitted infections (STIs) as well as systematic surveillance of the behaviour that spreads them. It aims to use these data together to build up a comprehensive picture of the HIV/AIDS epidemic.
