IntroductionSwaziland’s severe HIV epidemic inspired an early national response since the late 1980s, and regular reporting of program outcomes since the onset of a national antiretroviral treatment (ART) program in 2004. We assessed effectiveness outcomes and mortality trends in relation to ART, HIV testing and counseling (HTC), tuberculosis (TB) and prevention of mother to child transmission (PMTCT).MethodsData triangulated include intervention coverage and outcomes according to program registries (2001-2010), hospital admissions and deaths disaggregated by age and sex (2001-2010) and population mortality estimates from the 1997 and 2007 censuses and the 2007 demographic and health survey.ResultsBy 2010, ART reached 70% of the estimated number of people living with HIV/AIDS with CD4<350/mm3, with progressively improving patient retention and survival. As of 2010, 88% of health facilities providing antenatal care offered comprehensive PMTCT services. The HTC program recorded a halving in the proportion of adults tested who were HIV-infected; similarly HIV infection rates among HIV-exposed babies halved from 2007 to 2010. Case fatality rates among hospital patients diagnosed with HIV/AIDS started to decrease from 2005–6 in adults and especially in children, contrasting with stable case fatality for other causes including TB. All-cause child in-patient case fatality rates started to decrease from 2005–6. TB case notifications as well as rates of HIV/TB co-infection among notified TB patients continued a steady increase through 2010, while coverage of HIV testing and CPT for co-infected patients increased to above 80%.ConclusionAgainst a background of high, but stable HIV prevalence and decreasing HIV incidence, we documented early evidence of a mortality decline associated with the expanded national HIV response since 2004. Attribution of impact to specific interventions (versus natural epidemic dynamics) will require additional data from future household surveys, and improved routine (program, surveillance, and hospital) data at district level.

In Swaziland, where one in four adults is HIV positive, identifying and addressing barriers to a strong referral system is critical to ensure continuity of care for HIV positive individuals. This study examines the referral system from the perspectives of health providers, community health workers, traditional healers, clients seeking facility-based care, and managers of private health organizations. Structured and semi-structured questionnaires were administered to 52 senior providers, 161 providers, and 307 clients in 52 health facilities. In 82 randomly selected communities, 81 traditional healers and 247 CHWs also participated. Staff from private health agencies providing HIV-related care were also interviewed.Referral is commonly understood as sending clients to seek care at higher level facilities and is an individualized process dependent on various factors. Providers sending clients rarely hear back on any regular basis about those clients. Referrals and linkages for certain services are particularly weak including nutrition support, psychosocial support, palliative care and homebased care. Many providers recommended that referral protocols with improved communication tools are needed and said referred clients should be given priority at referral-receiving sites. Policy recommendations include: referral form redesign; formalizing or reforming the referral protocol; strengthening communication and linkages between community-and facility-based providers; and improving patient-flow at referral sites.

Background In resource-limited settings where anti-retroviral treatment (ART) is being scaled-up, the World Health Organization (WHO) recommends the surveillance of transmitted HIV drug resistance (HIVDR). We used the WHO's HIVDR threshold survey method to assess transmitted HIVDR in three antenatal clinic (ANC) sites along the corridor between the two most populous cities in Swaziland, where ART was introduced in 2003. Methods From July–August 2006, remnant sera were aliquoted from HIV serosurvey specimens collected from 70 primagravidas <25 years old attending ANC during the national HIV serosurvey. Genotyping was performed at the National Institute for Communicable Diseases, South Africa. Transmitted resistance was defined by the WHO's surveillance list of mutations. HIVDR prevalence was categorized using the WHO's threshold survey binomial sequential sampling method. Results Among the 70 eligible specimens, 61 were sequenced – 60 (98%) were identified as subtype C and one as subtype B. No major nucleoside or non-nucleoside reverse transcriptase inhibitor mutations occurred among the first 34 consecutive specimens, which supported a transmitted resistance categorization to these drug classes as <5%. One protease inhibitor mutation, M46I, was seen among the first 44 specimens, supporting a categorization of PI resistance as <5%. Conclusion Our survey indicates that prevalence of transmitted HIVDR among recently infected pregnant women along the Manzini-Mbabane corridor is low (<5%). Surveys will be carried out in this area biannually and may be extended to other areas. Surveys for transmitted resistance make up one element among a spectrum of activities to assess and support minimization of HIVDR.
