Abstract
Widespread testing for the respiratory syndrome coronavirus-2 (SARS-CoV-2) will represent an important part of any strategy designed to safely reopen societies from lockdown. Healthcare settings have the potential to become reservoirs of infectivity, and therefore many hospital trusts are beginning to carry out routine screening of staff and patients. This could promote the effective cohorting of patients and reduce the rate of nosocomial infection. However, for various reasons, some individuals may refuse this testing. Here we highlight this as an emergent ethicolegal issue which we expect to become increasingly relevant as testing becomes ubiquitous. We explore this position from an ethical and legal perspective, determining whether refusal of testing is acceptable under UK law. Individual patients refusing testing could undermine a hospital's testing strategy; therefore clinicians and policy makers must prospectively determine the best course of action if this were to occur.

Abstract
Encephalitis, inflammation of the brain, is most commonly caused by a viral infection (especially herpes simplex virus [HSV] type 1 in the UK) although autoimmune causes, such as N-methyl D-aspartate receptor (NMDAR) antibody encephalitis, are increasingly recognised. Most patients present with a change in consciousness level and may have fever, seizures, movement disorder or focal neurological deficits. Diagnosis hinges crucially on lumbar puncture and cerebrospinal fluid (CSF) examination, but imaging and electroencephalography (EEG) may also be helpful. Treatment of HSV encephalitis with aciclovir dramatically improves outcome, but the optimal management of autoimmune encephalitis is still uncertain. Many patients with encephalitis are left with residual physical or neuropsychological deficits which require long-term multidisciplinary management. Here we review assessment of patients with suspected encephalitis, general aspects of management and areas of ongoing research.

Abstract
OBJECTIVE To quantify and characterise missed opportunities for earlier HIV diagnosis in patients diagnosed with advanced HIV. DESIGN A retrospective observational cohort study. SETTING A central tertiary medical centre in Israel. MEASURES The proportion of patients with advanced HIV, the proportion of missed opportunities to diagnose them earlier, and the rate of clinical indicator diseases (CIDs) in those patients. RESULTS Between 2010 and 2015, 356 patients were diagnosed with HIV, 118 (33.4%) were diagnosed late, 57 (16%) with advanced HIV disease. Old age (OR=1.45 (95% CI 1.16 to 1.74)) and being heterosexual (OR=2.65 (95% CI 1.21 to 5.78)) were significant risk factors for being diagnosed late. All patients with advanced disease had at least one CID that did not lead to an HIV test in the 5 years prior to AIDS diagnosis. The median time between CID and AIDS diagnosis was 24 months (IQR 10-30). 60% of CIDs were missed by a general practitioner and 40% by a specialist. CONCLUSIONS Missed opportunities to early diagnosis of HIV occur in primary and secondary care. Lack of national guidelines, lack of knowledge regarding CIDs and communication barriers with patients may contribute to a late diagnosis of HIV.

Late Presentation of HIV Infection: Prevalence, Trends, and the Role of HIV Testing Strategies in Guangzhou, China, 2008-2013. BIOMED RESEARCH INTERNATIONAL 2016; 2016:1631878. [PMID: 27761466 PMCID: PMC5059519 DOI: 10.1155/2016/1631878] [Citation(s) in RCA: 19] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 06/07/2016] [Revised: 08/10/2016] [Accepted: 09/06/2016] [Indexed: 12/13/2022]
Abstract
Background. The prevalence, trends, and the role of different HIV testing strategies in late presentation of HIV infection in China were unknown. Methods. Data of newly reported HIV cases in Guangzhou between 2008 and 2013 was analyzed to examine the prevalence, trends, and characteristics of late presentation of HIV infection by three types of HIV testing strategies. Results. Overall, 53.2% (1412/2653) and 27.3% (724/2653) met the criteria of late presentation and presentation with advanced HIV disease. The overall trend of late presentation of HIV infection within the study period was declining. Late presentation was 62.9% in 2008 and dropped to 43.3% in 2013 (P < 0.001); presentation with advanced HIV disease was 40.3% in 2008 and dropped to 15.2% in 2013 (P < 0.001). Of the three testing strategies, PITC presented higher odds of both late presentation [AOR (95% CI): PITC versus VCT: 1.37 (1.09, 1.73); PITC versus MHT: 3.09 (2.16, 4.42)] and presentation with advanced HIV disease [AOR (95% CI): PITC versus VCT: 1.65 (1.29, 2.11); PITC versus MHT: 13.14 (8.47, 20.39)]. Conclusions. Although the late presentation of HIV infection was declining, it was still high in Guangzhou. The worse situation among PITC cases urges the policy adjustment in medical settings to increase early HIV diagnosis.

Factors associated with spontaneous clearance of chronic hepatitis C virus infection. J Hepatol 2016; 65:266-72. [PMID: 27155531 DOI: 10.1016/j.jhep.2016.04.030] [Citation(s) in RCA: 43] [Impact Index Per Article: 5.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/26/2015] [Revised: 04/25/2016] [Accepted: 04/26/2016] [Indexed: 02/08/2023]
Abstract
BACKGROUND & AIMS Spontaneous clearance of chronic hepatitis C virus (HCV) infection (CHC) is rare. We conducted a retrospective case-control study to identify rates and factors associated with spontaneous clearance of CHC. METHODS We defined cases as individuals who spontaneously resolved CHC, and controls as individuals who remained chronically infected. We used data obtained on HCV testing between 1994 and 2013 in the West of Scotland to infer case/control status. Specifically, untreated patients with ⩾2 sequential samples positive for HCV RNA ⩾6months apart followed by ⩾1 negative test, and those with ⩾2 positive samples ⩾6months apart with no subsequent negative samples were identified. Control patients were randomly selected from the second group (4/patient of interest). Case notes were reviewed and patient characteristics obtained. RESULTS 25,113 samples were positive for HCV RNA, relating to 10,318 patients. 50 cases of late spontaneous clearance were identified, contributing 241 person-years follow-up. 2,518 untreated, chronically infected controls were identified, contributing 13,766 person-years follow-up, from whom 200 controls were randomly selected. The incidence rate of spontaneous clearance was 0.36/100 person-years follow-up, occurring after a median 50months' infection. Spontaneous clearance was positively associated with female gender, younger age at infection, lower HCV RNA load and co-infection with hepatitis B virus. It was negatively associated with current intravenous drug use. CONCLUSIONS Spontaneous clearance of CHC occurs infrequently but is associated with identifiable host and viral factors. More frequent HCV RNA monitoring may be appropriate in selected patient groups. LAY SUMMARY Clearance of hepatitis C virus infection without treatment occurs rarely once chronic infection has been established. We interrogated a large Scottish patient cohort and found that it was more common in females, patients infected at a younger age or with lower levels of HCV in the blood, and patients co-infected with hepatitis B virus. Patients who injected drugs were less likely to spontaneously clear chronic infection.

Abstract
BACKGROUND Hepatitis B (HBV), hepatitis C (HCV), and HIV blood-borne viruses (BBV) are associated with chronic ill health and mortality. Early diagnosis reduces disease transmission, delays progression, and improves outcomes. Routine opt-out testing for BBV in primary care may be viable in identifying unknown disease. AIM To assess the viability and yield of routine opt-out testing for BBV. DESIGN AND SETTING A multicentre, prospective, routine opt-out testing study of BBV in primary care between September 2014 and February 2015 across four sites in Dublin, Ireland. METHOD All adult patients attending for routine blood tests were offered an additional BBV test during a 6-month period. All individuals were given an information leaflet before phlebotomy and were given the choice to opt out of BBV testing. RESULTS In total, 1188 patients were invited to participate in the study and 1063 (89.5%) opted to be tested (95% confidence interval [CI] = 87.7% to 91.2%). A total of 125 patients (10.5%) opted out. There were 10 positive results, four new diagnoses, and six previously known. There were two new HBV and two new HCV diagnoses, a yield of four per 1000 (95% CI = 0.9 to 7.5 cases per 1000). No new HIV cases were diagnosed. CONCLUSION This study indicates that testing for BBV in patients presenting for routine blood tests in primary care is viable. The yield of HBV and HCV suggests that opt-out testing should be considered in primary care to increase detection rates of BBV.

Abstract
Adolescence is a time of sexual risk-taking and experimentation but also vulnerability. Young people may present to general physicians with systemic symptoms of sexually transmitted infections (STIs), such as arthritis, hepatitis or rash, but may not necessarily volunteer information about sexual activity. It is important for physicians to ask directly about sexual risks and if appropriate test for STIs and pregnancy. Knowing how to take a sexual history and consent a patient for an HIV test are core medical skills that all physicians should be trained to competently perform. Safeguarding young people is the responsibility of all healthcare professionals who come into contact with them, and young victims of abuse may present with physical symptoms such as abdominal pain or deliberate self-harm. We must all be aware of indicators of both child sexual exploitation and HIV infection and not be afraid to ask potentially awkward questions. If we don't we may miss vital opportunities to prevent or minimise harm to young people.

Abstract
OBJECTIVES Kaposi's sarcoma (KS), invasive cervical carcinoma (ICC) and non-Hodgkin lymphoma (NHL) have been listed as AIDS-defining cancers (ADCs) by the Centers for Disease Control and Prevention since 1993. Despite this, HIV screening is not universally mentioned in ADC treatment guidelines. We examined screening practices at a tertiary centre serving a population where HIV seroprevalence is 0.4%. METHODS Patients with KS, ICC, NHL and Hodgkin lymphoma (HL), treated at Lausanne University Hospital between January 2002 and July 2012, were studied retrospectively. HIV testing was considered part of the oncology work-up if performed between 90 days before and 90 days after the cancer diagnosis date. RESULTS A total of 880 patients were examined: 10 with KS, 58 with ICC, 672 with NHL and 140 with HL. HIV testing rates were 100, 11, 60 and 59%, and HIV seroprevalence was 60, 1.7, 3.4 and 5%, respectively. Thirty-seven patients (4.2%) were HIV-positive, of whom eight (22%) were diagnosed at oncology work-up. All newly diagnosed patients had CD4 counts < 200 cells/μL and six (75%) had presented to a physician 12-236 weeks previously with conditions warranting HIV testing. CONCLUSIONS In our institution, only patients with KS were universally screened. Screening rates for other cancers ranged from 11 to 60%. HIV seroprevalence was at least fourfold higher than the population average. As HIV-positive status impacts on cancer patient medical management, HIV screening should be included in oncology guidelines. Further, we recommend that opt-out screening should be adopted in all patients with ADCs and HL.

Abstract
BACKGROUND UK HIV guidelines identify 37 clinical indicator conditions for adult HIV infection that should prompt an HIV test. However, few data currently exist to show their predictive value in identifying undiagnosed HIV. AIM To identify symptoms and clinical diagnoses associated with HIV infection and assess their relative importance in identifying HIV cases, using data from The Health Improvement Network (THIN) general practice database. DESIGN AND SETTING A case-control study in primary care. METHOD Cases (HIV-positive patients) were matched to controls (not known to have HIV). Data from 939 cases and 2576 controls were included (n = 3515). Statistical analysis assessed the incidence of the 37 clinical conditions in cases and controls, and their predictive value in indicating HIV infection, and derived odds ratios (ORs) for each indicator condition. RESULTS Twelve indicator conditions were significantly associated with HIV infection; 74.2% of HIV cases (n = 697) presented with none of the HIV indicator conditions prior to diagnosis. The conditions most strongly associated with HIV infection were bacterial pneumonia (OR = 47.7; 95% confidence interval [CI] = 5.6 to 404.2) and oral candidiasis (OR = 29.4; 95% CI = 6.9 to 125.5). The signs and symptoms most associated with HIV were weight loss (OR = 13.4; 95% CI = 5.0 to 36.0), pyrexia of unknown origin (OR = 7.2; 95% CI = 2.8 to 18.7), and diarrhoea (one or two consultations). CONCLUSION This is the first study to quantify the predictive value of clinical diagnoses related to HIV infection in primary care. In identifying the conditions most strongly associated with HIV, this study could aid GPs in offering targeted HIV testing to those at highest risk.

Abstract
The aim of the 2010 BHIVA audit was to assess the impact of the 2008 UK HIV testing guidelines on clinical practice. Here, we report one aspect of the audit comprising a survey of local testing policy and practice at centres providing adult HIV services across the UK. Selected recommendations from the 2008 national HIV testing guidelines were assessed as target outcomes and the percentages of sites and subjects meeting these recommendations were calculated. One hundred and thirty-two sites responded to the survey and many are actively promoting HIV testing locally. Sites report HIV testing is routine in genitourinary (GU) medicine and antenatal services but offered selectively in other clinical areas. Encouragingly, 21 (16%) report some local general practitioner practices are offering testing routinely to new patients at registration. However, the time to receive non-urgent HIV test results exceeds 72 hours in 29% of sites. In conclusion, HIV testing needs to continue to expand across clinical settings to reduce the number of patients living with undiagnosed infection. Laboratory turnaround time needs to improve to ensure non-urgent HIV test results are available within 72 hours.

Abstract
Background Initiating therapy with a low CD4 cell count is associated with a substantially greater risk of disease progression and death than earlier initiation. We examined factors associated with late presentation of HIV using the new European consensus definition (CD4 cell count <350 cells/mm3) and mortality. Methods Patients newly diagnosed with HIV infection at a UK clinic were recruited from January 1996 to May 2010. Factors associated with late presentation were assessed using logistic regression. Factors associated with mortality rates were analysed using Poisson regression. Results Of the 1536 included in the analysis, 86% were male and 10% were aged 50 years and older. Half the cohort (49%) had a CD4 cell count below 350 cells/mm3 at presentation (“late presentation”). The frequency of late presentation was highest in those aged 50 years or older and remained unchanged over time (64.3% in 1996-1998 and 65.4% in 2008-2010). In contrast, among those aged less than 50 years, the proportion with late presentation decreased over time (57.1% in 1996-1998 and 38.5% in 2008-2010). Other factors associated with late presentation were African ethnicity and being a male heterosexual. The mortality rate was 15.47/1000 person-years (pyrs) (95%-CI: 13.00-18.41). When compared with younger adults, older individuals had a higher mortality, after adjusting for confounders (rate ratio (RR) = 2.87; 95%-CI: 1.88-4.40). Conclusions Older adults were more likely to present late and had a higher mortality. Initiatives to expand HIV testing in clinical and community setting should not neglect individuals aged over 50.

Abstract
Human immunodeficiency virus-related oral lesions (HIV-OLs), such as oral candidiasis (OC) and oral hairy leukoplakia (OHL), have been recognized as indicators of immune suppression since the beginning of the global HIV epidemic. The diagnosis and management of HIV disease and spectrum of opportunistic infection has changed over the past 30 years as our understanding of the infection has evolved. We investigated the following controversial topics: (i) Are oral manifestations of HIV still relevant after the introduction of highly active antiretroviral therapy (HAART)? (ii) Can we nowadays still diagnose HIV infection through oral lesions? (iii) Is the actual classification of oral manifestations of HIV adequate or does it need to be reviewed and updated? (iv) Is there any novelty in the treatment of oral manifestations of HIV infection? Results from extensive literature review suggested the following: (i) While HAART has resulted in significant reductions in HIV-OLs, many are still seen in patients with HIV infection, with OC remaining the most common lesion. While the relationship between oral warts and the immune reconstitution inflammatory syndrome is less clear, the malignant potential of oral human papillomavirus infection is gaining increasing attention. (ii) Effective antiretroviral therapy has transformed HIV from a fatal illness to a chronic manageable condition and as a result expanded screening policies for HIV are being advocated both in developed and in developing countries. Affordable, reliable, and easy-to-use diagnostic techniques have been recently introduced likely restricting the importance of HIV-OLs in diagnosis. (iii) The 1993 EC-Clearinghouse classification of HIV-OLs is still globally used despite controversy on the relevance of periodontal diseases today. HIV-OL case definitions were updated in 2009 to facilitate the accuracy of HIV-OL diagnoses by non-dental healthcare workers in large-scale epidemiologic studies and clinical trials. (iv) Research over the last 6 years on novel modalities for the treatment of HIV-OLs has been reported for OC and OHL.

Abstract
BACKGROUND Through migration, diversity of chronic hepatitis B virus (HBV) infection has changed, affecting disease burden and control. We describe clinical and viral characteristics of chronic HBV in the United Kingdom. METHODS A total of 698 individuals with chronic HBV infection were recruited from referral liver centers. Demographic, clinical, and laboratory data were collected. RESULTS Sixty-one percent of patients were male, 80% were not born in the United Kingdom, and the largest ethnicity was East/Southeast Asian (36%). Twenty-two percent were hepatitis B e antigen (HBeAg) seropositive; 20.4% (59/289) had cirrhosis and 10 (1.7%) had hepatocellular carcinoma. Genotype D was most common (31%) followed by A, C, B, and E (20%, 20%, 19%, and 9%, respectively). Genotype was significantly associated with country of birth, length of time in the United Kingdom, HBeAg status, and precore and basal core promoter mutations. One-third were on treatment, with men independently more likely to be treated. Only 18% of those on treatment were on recommended first-line therapies, and 30% were on lamivudine monotherapy. Among treated individuals, 27% had antiviral drug resistance. Testing rates for human immunodeficiency virus, hepatitis C virus, and delta coinfections were low. CONCLUSIONS We demonstrated diversity of chronic HBV infections in UK patients, suggesting that optimal management requires awareness of the variable patterns of chronic HBV in countries of origin. We also found less-than-optimal clinical management practices, possible gender-based treatment bias, and the need to improve testing for coinfections.

Abstract
The late diagnosis of HIV in patients across the UK is an increasing problem. Here, we report on a retrospective case-notes audit carried out to assess the impact of the 2008 UK HIV testing guidelines on clinical practice and identify missed opportunities for HIV testing. The audit was carried out in 2010 and focussed on patients with newly diagnosed HIV at centres providing adult HIV services across the UK. Data were collected on 1,112 patients, of whom 52.2% were found to have a late HIV diagnosis as defined as a CD4 T lymphocyte count of <350 cells/mm3. Most patients (62.6%) were diagnosed in traditional settings, with a significant increase in those diagnosed with HIV in non-traditional settings (33%) compared with the 2003 audit (18.5%) (p<0.001). The most frequent indicator conditions that patients had experienced were chronic diarrhoea or weight loss, sexually transmitted infection, blood dyscrasia or lymphadenopathy. A quarter of patients were identified as having had a missed opportunity for earlier diagnosis. Based on our results, we suggest that HIV testing needs to continue to expand across clinical settings to reduce the number of patients living with undiagnosed HIV infection.

Abstract
In the 1980s the outcome of patients with herpes simplex encephalitis was shown to be dramatically improved with aciclovir treatment. Delays in starting treatment, particularly beyond 48 h after hospital admission, are associated with a worse prognosis. Several comprehensive reviews of the investigation and management of encephalitis have been published. However, their impact on day-to day clinical practice appears to be limited. The emergency management of meningitis in children and adults was revolutionised by the introduction of a simple algorithm as part of management guidelines. In February 2008 a group of clinicians met in Liverpool to begin the development process for clinical care guidelines based around a similar simple algorithm, supported by an evidence base, whose implementation is hoped would improve the management of patients with suspected encephalitis.

Abstract
BACKGROUND Early diagnosis of HIV infection reduces morbidity and mortality associated with late presentation. Despite UK guidelines, the HIV testing rate has not increased. We have introduced universal HIV screening in an open-access returning traveller clinic. METHODS Data were prospectively recorded for all patients attending the open-access returning traveller clinic between August 2008 and December 2010. HIV testing was offered to all patients from May 2009; initially testing with laboratory samples (phase 1) and subsequently a point-of-care test (POCT) (phase 2). RESULTS A total of 4965 patients attended the clinic; 1342 in phase 0, 792 in phase 1 and 2831 in phase 2. Testing rates for HIV increased significantly from 2% (38 of 1342) in phase 0 to 23.1% (183 of 792) in phase 1 and further increased to 44.5% (1261 of 2831) during phase 2 (P < 0.0001). Two new diagnoses of HIV-1 were identified in phase 1 (1.1% of tested); seven patients had a reactive POCT test in phase 2, of whom five (0.4% of those tested) were confirmed in a 4th generation assay. The patients with false reactive tests had a concurrent Plasmodium falciparum infection. Patients travelling to the Middle East and Europe were less likely to accept an HIV test with POCT. CONCLUSIONS A nurse-delivered universal point-of-care HIV testing service has been successfully introduced and sustained in an acute medical clinic in a low-prevalence country. Caution is required in communicating reactive results in low-prevalence settings where there may be alternative diagnoses or a low population prevalence of HIV infection.

Abstract
The aims of this study were to observe trends in testing for HIV between 2004 and 2007 in one London, UK, hospital and to observe the seroprevalence of HIV within subgroups. Tests were grouped according to source and reason for testing. A total of 58,720 tests were considered (HIV-1 seroprevalence 0.9%). The majority (75.4%) of tests were performed as part of routine and opt-out protocols including antenatal and genitourinary (GU) screening. Among people specifically seeking HIV testing, the HIV seroprevalence was 3.5%. Medical specialties performed fewer tests but a high HIV seroprevalence was observed, including infectious disease (seroprevalence 4.4%) and other medical specialties (seroprevalence 3.4%). A small number of specialties performed few HIV tests. HIV testing was cost-effective in virtually all settings. This study suggests that more HIV tests could be performed, for example, in acute medicine, and training might increase the number of tests offered in some settings. The most effective way of increasing testing appears to be opt-out testing.

Abstract
The objective of this study was to offer HIV testing to all patients attending the acute medical admissions unit (AMU) in Newcastle upon Tyne to assess feasibility, acceptability and point prevalence in accordance with the 2008 UK National HIV testing guidelines. A prospective audit was performed offering HIV testing to all patients with the capacity to give verbal consent who attended the AMU. In total, 3,753 eligible patients were admitted during the audit period and 586 (15.6%) were considered for testing. Of those approached, 108 (18.4%) were clinically ineligible to test and 478 were offered a test. In the 396 patients who consented (82.8%), there were two new HIV diagnoses (point prevalence 0.5%). Offering HIV testing in an AMU setting is feasible and acceptable to patients. The high uptake rate but low proportion of admissions tested suggests a lack of confidence of medical staff in offering a test. Misconceptions regarding HIV testing remain and greater education is required for healthcare workers.

Abstract
Minimum accuracy of HIV diagnostic tests is considered the pillar on which testing strategies for all settings must be based. Systematic reviews and meta-analyses have shown that performance of the same test in different settings may vary according to several factors, resulting in different confidence intervals for sensitivity and specificity. Prevalence of HIV infection may influence observed test accuracy. The purpose of this article is to use the knowledge from meta-analyses of general diagnostic tests to inform the specific field of HIV diagnostic strategies. We propose the 'Bayesian' thinking: considering the pretest probability (i.e., prevalence, risk factors) and understanding test limitations to estimate a post-test probability of HIV diagnosis. Cost-effectiveness analysis, patient preferences and ethical issues must also be considered in HIV testing strategies.

Abstract
OBJECTIVES In the UK, one-third of human immunodeficiency virus (HIV)-infected individuals are unaware of their diagnosis, and of those diagnosed a similar proportion have late stage disease. To address this National guidelines have been introduced promoting HIV testing across all medical specialities. We investigated HIV testing patterns in an inner London area with high local HIV prevalence, to identify missed opportunities for HIV testing and its consequences. METHODS All human immunodeficiency virus (HIV) tests performed in 2008 at Guys and St Thomas' NHS Trust virology department were reviewed. Tests were stratified for location of request. Case-note review was carried out on all hospital HIV-positive diagnoses outside the genitourinary medicine (GUM) or screening settings to establish the circumstances surrounding the test, and missed opportunities for previous HIV testing. RESULTS A total of 40,883 HIV tests were performed in 36,395 individuals. Three hundred and fifty-four (1%) tested positive. Excluding those from GUM or screening settings, 34 (2.8%) of the 1225 inpatients, 17 (0.3%) of the 5303 outpatients and 68 (1.12%) of the 5746 from primary care tested positive. Nineteen (41%) of 46 evaluable hospital diagnoses had presented to local healthcare services within the previous 12 months, 17 (37%) with an HIV indicator condition, but had not been tested. Of the 5303 outpatient tests conducted, 3148 (59%) were performed by either fertility or renal specialist teams. Other specialties conducted relatively few tests. The mean cost of admission for those diagnosed as an inpatient was £36,625 (range £331-223,000). The total cost for the 12 inpatients, who had presented to services in the preceding year but had not been tested was £439,500. CONCLUSION Despite large numbers of HIV tests as screening tests in GUM and antenatal settings, relatively few tests occurred elsewhere with profound costs. Missed opportunities to access this high-prevalence HIV population is concerning and urgent engagement of primary, secondary and tertiary healthcare systems to increase HIV testing and prevent late-stage diagnoses is underway.
