A study amongst 2443 people in Zambia, recruited from HIV clinics and community organisations, found that social ostracism, rejection by sexual partners and fear of not being able to handle antiretroviral therapy (ART) were the reasons people most often gave for not testing for HIV. A session at the 19th International AIDS Conference (AIDS 2012) in Washington heard that, perhaps surprisingly, in terms of demographic characteristics, people living in cities were far less likely to test than people in rural areas.
