Determinants of partner and family-based index case HIV testing among adults receiving antiretroviral therapy in Asella, Ethiopia
This facility-based study in Asella, Ethiopia, found that while 71.7% of adults on antiretroviral therapy facilitated HIV testing for partners or family members, this uptake was significantly driven by marital status, HIV status disclosure, provider-led counseling, and good HIV knowledge.

HIV remains a persistent challenge, particularly in sub-Saharan Africa, where the virus continues to spread despite global efforts to contain it. A central goal of modern public health is not just to treat those already infected, but to find those who do not yet know they carry the virus. One powerful strategy for doing this is called index case testing. Instead of waiting for people to walk into a clinic on their own, this approach asks a person who is already living with HIV and receiving treatment to help identify their close contacts—spouses, children, and other family members—who may have been exposed. The person already in care, known as the index client, is supported to encourage these contacts to get tested voluntarily. If successful, this method can uncover hidden infections and link new patients to life-saving treatment, effectively closing the gap between those who need care and those who are receiving it.
In the town of Asella, Ethiopia, researchers set out to understand how well this strategy is working in real-world clinics and what factors help or hinder its success. They focused on adults who were already receiving antiretroviral therapy, the daily medication that keeps the virus under control. Between August and September 2023, the team visited three different health facilities in the town: a large referral hospital, a private general hospital, and a local health center. They spoke directly with 410 adults who met the study's criteria, asking them whether they had helped get their partners or family members tested for HIV. The researchers were looking for the specific conditions that made people more likely to take this step, hoping to find ways to improve the system for everyone.
The results showed that the strategy is being used, but there is still room for significant improvement. Out of the 410 adults interviewed, roughly 72 percent reported that at least one family member or sexual partner had been tested through this approach. This means that for nearly three out of every four people in treatment, the network of care extended to their loved ones. However, the study also revealed that for the remaining quarter, this vital link was missing. The researchers found that the likelihood of a partner or family member getting tested depended heavily on a few key factors. People who were married or living with a partner were much more likely to have their contacts tested compared to those who were single. Similarly, those who were divorced or widowed showed an even stronger tendency to have their contacts tested than single individuals.
Perhaps the most powerful drivers of success were communication and knowledge. Adults who had openly shared their HIV status with their loved ones were far more likely to have those loved ones get tested. The study also found that when healthcare providers actively guided the conversation, asking specific questions and offering structured support, the rates of testing jumped significantly. It was not just about the patient deciding on their own; the presence of a trained professional who facilitated the discussion made a profound difference. Furthermore, individuals who possessed a solid understanding of how HIV works and how treatment protects others were more inclined to bring their families into the testing process.
The researchers were careful to note that their study could not prove that one factor caused the other, as they looked at all these elements at a single point in time. They also relied on what the patients told them, rather than checking medical records to confirm if the testing actually happened, which means the numbers might be influenced by how people remember or wish to present their actions. Despite these limitations, the patterns were clear and consistent. The study suggests that to reach more people, health programs need to focus on strengthening the role of healthcare providers in guiding these conversations, supporting patients to disclose their status safely, and ensuring that everyone has a clear understanding of the disease. By addressing these specific areas, clinics in Asella and similar settings can move closer to the goal of ensuring that no one living with HIV or at risk of it remains undiagnosed.
