Background: HIV testing at birth may improve early treatment, but concerns remain about feasibility and retention of infants in care. In 2017, point-of-care (POC) HIV birth testing was introduced into routine care at 3 high-volume maternity health facilities in Eswatini. Methods: POC birth testing was offered to HIV-exposed infants (HEI) born at, or presenting to, 3 maternities within 3 days of birth. Data were collected from a project-specific EID test request form and routine registers on all tests conducted from August 1, 2017 to November 30, 2018, including retesting at 6-8 weeks for infants testing negative at birth and six-month retention in HIV care and viral load suppression among infants testing HIV-positive at birth. Results: Of 4322 eligible HEI, 3311 (76.6%) were tested. Twenty-six HIV-infected infants were identified (positivity rate 0.8%) and 25 initiated on antiretroviral therapy (ART) (96.1%). The median time from sample collection to ART initiation was 20.50 days (IQR 14-45). Twenty-one (84%) ART-initiated infants were on ART at 6 months after initiation. Nineteen infants (90.5%) had viral load test information at 6 months and 16 (84.2%) were virally suppressed. Of 3126 HEI testing negative at birth, 3004 (96.1%) were linked to laboratory databases and 2744 (91.3%) were retested at 6-8 weeks, with 9 (0.3%) additional infants testing HIV-positive. Conclusions: Uptake of POC birth testing was high in Eswatini with low HIV positivity. Almost all infants identified HIV-positive at birth were initiated on ART, with high retention in care and viral suppression. Birth testing did not seem to significantly reduce subsequent 6-8-week testing.
BackgroundInvestigation of household contacts exposed to infectious tuberculosis (TB) is widely recommended by international guidelines to identify secondary cases of TB and limit spread. There is little data to guide the use of contact investigations outside of the household, despite strong evidence that most TB infections occur outside of the home in TB high burden settings. In older adolescents, the majority of infections are estimated to occur in school. Therefore, as part of a project to increase active case finding in Swaziland, we performed school contact investigations following the identification of a student with infectious TB.MethodsThe Butimba Project identified 7 adolescent TB index cases (age 10–20) with microbiologically confirmed disease attending 6 different schools between June 2014 and March 2015. In addition to household contact investigations, Butimba Project staff worked with the Swaziland School Health Programme (SHP) to perform school contact investigations. At 6 school TB screening events, between May and October 2015, selected students underwent voluntary TB screening and those with positive symptom screens provided sputum for TB testing.ResultsAmong 2015 student contacts tested, 177 (9%) screened positive for TB symptoms, 132 (75%) produced a sputum sample, of which zero tested positive for TB. Household contact investigations of the same index cases yielded 40 contacts; 24 (60%) screened positive for symptoms; 19 produced a sputum sample, of which one case was confirmed positive for TB. The odds ratio of developing TB following household vs. school contact exposure was significantly lower (OR 0.0, 95% CI 0.0 to 0.18, P = 0.02) after exposure in school.ConclusionSchool-based contact investigations require further research to establish best practices in TB high burden settings. In this case, a symptom-based screening approach did not identify additional cases of tuberculosis. In comparison, household contact investigations yielded a higher percentage of contacts with positive TB screens and an additional tuberculosis case.
Background: Testing for HIV at birth has the potential to identify infants infected in utero, and allows for the possibility of beginning treatment immediately after birth; point of care (POC) testing allows rapid return of results and faster initiation on treatment for positive infants. Eswatini piloted birth testing in three public maternities for over 2 years. Methods: In order to assess the acceptability of POC birth testing in the pilot sites in Eswatini, interviews were held with caregivers of HIV-exposed infants who were offered birth testing (N = 28), health care workers (N = 14), and policymakers (N = 10). Participants were purposively sampled. Interviews were held in English or SiSwati, and transcribed in English. Transcripts were coded by line, and content analysis and constant comparison were used to identify key themes for each respondent type. Results: Responses were categorized into: knowledge, experience, opinions, barriers and challenges, facilitators, and suggestions to improve POC birth testing. Preliminary findings reveal that point of care birth testing has been very well received but challenges were raised. Most caregivers appreciated testing the newborns at birth and getting results quickly, since it reduced anxiety of waiting for several weeks. However, having a favorable experience with testing was linked to having supportive and informed family members and receiving a negative result. Caregivers did not fully understand the need for blood draws as opposed to tests with saliva, and expressed the fears of seeing their newborns in pain. They were specifically grateful for supportive nursing staff who respected their confidentiality. Health care workers expressed strong support for the program but commented on the high demand for testing, increased workload, difficulty with errors in the testing machine itself, and struggles to implement the program without sufficient staffing, especially on evenings and weekends when phlebotomists were not available. Policymakers noted that there have been challenges within the program of losing mothers to follow up after they leave hospital, and recommended stronger linkages to community groups. Conclusions: There is strong support for scale-up of POC birth testing, but countries should consider ways to optimize staffing and manage demand.
