Despite more than 25 documented outbreaks of Ebola since 1976, our understanding of the disease is limited, in particular the social, political, ecological, and economic forces that promote (or limit) its spread. In the following study, we seek to provide new ways of understanding the 2013-2016 Ebola pandemic. We use the term, 'pandemic,' instead of 'epidemic,' so as not to elide the global forces that shape every localized outbreak of infectious disease. By situating life histories via a biosocial approach, the forces promoting or retarding Ebola transmission come into sharper focus. We conclude that biomedical and culturalist claims of causality have helped obscure the role of human rights failings (colonial legacies, structural adjustment, exploitative mining companies, enabled civil war, rural poverty, and the near absence of quality health care, to name but a few) in the genesis of the 2013-16 pandemic. From early 20th century smallpox and influenza outbreaks to 21st century Ebola, transnational relations of inequality continue to be embodied as viral disease in West Africa, resulting in the preventable deaths of hundreds of thousands of people.

OBJECTIVE

To examine how the time from HIV testing to care referral and from referral to care linkage influenced time to care engagement for newly diagnosed HIV-infected adolescents.

METHODS

We evaluated the Care Initiative, a care linkage and engagement program for HIV-infected adolescents in 15 US clinics. We analyzed client-level factors, provider type, and intervals from HIV testing to care referral and from referral to care linkage as predictors of care engagement. Engagement was defined as a second HIV-related medical visit within 16 weeks of initial HIV-related medical visit (linkage).

RESULTS

At 32 months, 2143 youth had been referred. Of these, 866 were linked to care through the Care Initiative within 42 days and thus eligible for study inclusion. Of the linked youth, 90.8% were ultimately engaged in care. Time from HIV testing to referral (eg, ≤7 days versus >365 days) was associated with engagement [adjusted odds ratio = 2.91; 95% confidence interval (CI): 1.43 to 5.94] and shorter time to engagement (adjusted hazard ratio = 1.41; 95% CI: 1.11 to 1.79). Individuals with shorter care referral to linkage intervals (eg, ≤7 days versus 22-42 days) engaged in care faster (adjusted hazard ratio = 2.90; 95% CI: 2.34 to 3.60) and more successfully (adjusted odds ratio = 2.01; 95% CI: 1.04 to 3.89).

CONCLUSIONS

These data address a critical piece of the care continuum and can offer suggestions of where and with whom to intervene to best achieve the care engagement goals outlined in the US National HIV/AIDS Strategy. These results may also inform programs and policies that set concrete milestones and strategies for optimal care linkage timing for newly diagnosed adolescents.
