The incidence and mortality of kala-azar (KA, visceral leishmaniasis) in India have fallen drastically in the past few years, and in 2023 the reported KA incidence reached the threshold for elimination as a public health problem (<1 case/10 000 of population at subdistrict level). One of the strategies adopted by India's kala-azar elimination program (KAEP) was the regular independent assessment of the program implementation by teams of experts. We present the findings of assessments undertaken in 2019, 2021 and 2023, when the KAEP was in the last mile of elimination. Factors that contributed to its success were political commitment, intensified implementation, a strong network of KA partners and committed donors. Bottlenecks were observed in disease surveillance, data utilization, vector-control operations and program management at implementation. To sustain the gains and achieve validation of elimination, the KAEP should continue the following minimal essential services: optimized active and passive case detection and management of KA, post-KA dermal leishmaniasis, KA-HIV coinfection and relapse supported by vector-control interventions. Long-term measures that will sustain elimination are overall socioeconomic development, including improved living conditions, parallel with efficient surveillance and operational research that is aligned with the changing epidemiology of the disease.

BACKGROUND
We performed a systematic review to generate evidence on the association between cumulative human immunodeficiency virus (HIV) viraemia and health outcomes.
METHODS
Quantitative studies reporting on HIV cumulative viraemia (CV) and its association with health outcomes among people living with HIV (PLHIV) on antiretroviral treatment (ART) were included. We searched MEDLINE via PubMed, Embase, Scopus and Web of Science and conference abstracts from 1 January 2008 to 1 August 2022.
RESULTS
The systematic review included 26 studies. The association between CV and mortality depended on the study population, methods used to calculate CV and its level. Higher CV was not consistently associated with greater risk of acquire immunodeficiency syndrome–defining clinical conditions. However, four studies present a strong relationship between CV and cardiovascular disease. The risk was not confirmed in relation of increased hazards of stroke. Studies that assessed the effect of CV on the risk of cancer reported a positive association between CV and malignancy, although the effect may differ for different types of cancer.
CONCLUSIONS
CV is associated with adverse health outcomes in PLHIV on ART, especially at higher levels. However, its role in clinical and programmatic monitoring and management of PLHIV on ART is yet to be established.

BACKGROUND
Outbreaks of unknown aetiology in complex settings pose challenges and there is little information about investigation methods. We reviewed investigations into such outbreaks to identify methods favouring or impeding identification of the cause.
METHODS
We used two approaches: reviewing scientific literature and soliciting key informants. Case studies were developed through interviews with people involved and triangulated with documents available from the time of the investigation.
RESULTS
Ten outbreaks in African or Asian countries within the period 2007–2017 were selected. The cause was identified in seven, of which two had an unclear mode of transmission, and in three, neither origin nor transmission mode was identified. Four events were caused by infectious agents and three by chemical poisoning. Despite differences in the outbreaks, similar obstacles were noted: incomplete or delayed description of patients, comorbidities confounding clinical pictures and case definitions wrongly attributed. Repeated rounds of data collection and laboratory investigations were common and there was limited capacity to ship samples.
DISCUSSION
It was not possible to define activities that led to prompt identification of the cause in the case studies selected. Based on the observations, we conclude that basing case definitions on precise medical observations, implementing initial comprehensive data collection, including environmental, social and behavioural information; and involving local informants could save precious time and hasten implementation of control measures.

BACKGROUND
The burden of advanced HIV disease (AHD) and predictors of outcomes among people living with HIV (PLHIV) re-engaging in care are not well known.
METHODS
We conducted a retrospective cohort study of PLHIV who re-engaged in care after being lost to follow-up (LFU), from 2003 to 2019, in Myanmar. We calculated the incidence rates of attrition after re-engagement and performed Cox regression to identify risk factors for attrition.
RESULTS
Of 44 131 PLHIV who started antiretroviral treatment, 12 338 (28.0%) were LFU at least once: 7608 (61.6%) re-engaged in care, 4672 (61.4%) with AHD at re-engagement. The death and LFU rates were 2.21-fold (95% CI 1.82 to 2.67) and 1.46-fold (95% CI 1.33 to 1.61) higher among patients who re-engaged with AHD (p>0.001). Death in patients who re-engaged with AHD was associated with male sex (adjusted HR [aHR] 2.63; 95% CI 1.31 to 5.26; p=0.006), TB coinfection (aHR 2.26; 95% CI 1.23 to 4.14; p=0.008) and sex work (aHR 7.49, 95% CI 2.29 to 22.52; p<0.001). History of intravenous drug use was identified as a predictor of being LFU.
CONCLUSIONS
Re-engagement in HIV care in Myanmar is frequent and those who re-engage carry a high burden of AHD. As AHD at re-engagement is associated with higher attrition rates, implementation of differentiated interventions that enable earlier linkage to care and prompt identification and management of AHD in this population is necessary.

In sub-Saharan Africa models of care need to adapt to support continued scale up of antiretroviral therapy (ART) and retain millions in care. Task shifting, coupled with community participation has the potential to address the workforce gap, decongest health services, improve ART coverage, and to sustain retention of patients on ART over the long-term. The evidence supporting different models of community participation for ART care, or community-based ART, in sub-Saharan Africa, was reviewed. In Uganda and Kenya community health workers or volunteers delivered ART at home. In Mozambique people living with HIV/AIDS (PLWHA) self-formed community-based ART groups to deliver ART in the community. These examples of community ART programs made treatment more accessible and affordable. However, to achieve success some major challenges need to be overcome: first, community programs need to be driven, owned by and embedded in the communities. Second, an enabling and supportive environment is needed to ensure that task shifting to lay staff and PLWHA is effective and quality services are provided. Finally, a long term vision and commitment from national governments and international donors is required. Exploration of the cost, effectiveness, and sustainability of the different community-based ART models in different contexts will be needed.

BACKGROUND
Trauma is a leading cause of death and represents a major problem in developing countries where access to good quality emergency care is limited. Médecins Sans Frontières delivered a standard package of care in two trauma emergency departments (EDs) in different violence settings: Kunduz, Afghanistan, and Tabarre, Haiti. This study aims to assess whether this standard package resulted in similar performance in these very different contexts.
METHODS
A cross-sectional study using routine programme data, comparing patient characteristics and outcomes in two EDs over the course of 2014.
RESULTS
31 158 patients presented to the EDs: 22 076 in Kunduz and 9082 in Tabarre. Patient characteristics, such as delay in presentation (29.6% over 24 h in Kunduz, compared to 8.4% in Tabarre), triage score, and morbidity pattern differed significantly between settings. Nevertheless, both EDs showed an excellent performance, demonstrating low proportions of mortality (0.1% for both settings) and left without being seen (1.3% for both settings), and acceptable triage performance. Physicians' maximum working capacity was exceeded in both centres, and mainly during rush hours.
CONCLUSIONS
This study supports for the first time the plausibility of using the same ED package in different settings. Mapping of patient attendance is essential for planning of human resources needs.

BACKGROUND
In developing countries such as Pakistan, poor training of mid-level cadres of health providers, combined with unregulated availability of labour-inducing medication can carry considerable risk for mother and child during labour. Here, we describe the exposure to labour-inducing medication and its possible risks in a vulnerable population in a conflict-affected region of Pakistan.
METHODS
A retrospective cohort study using programme data, compared the outcomes of obstetric risk groups of women treated with unregulated oxytocin, with those of women with regulated treatment.
RESULTS
Of the 6379 women included in the study, 607 (9.5%) received labour-inducing medication prior to reaching the hospital; of these, 528 (87.0%) received unregulated medication. Out of 528 labour-inducing medication administrators, 197 (37.3%) traditional birth attendants (also known as dai) and 157 (29.7%) lady health workers provided unregulated treatment most frequently. Women given unregulated medication who were diagnosed with obstructed/prolonged labour were at risk for uterine rupture (RR 4.1, 95% CI 1.7–9.9) and severe birth asphyxia (RR 3.9, 95% CI 2.5–6.1), and those with antepartum haemorrhage were at risk for stillbirth (RR 1.8, 95% CI 1.0–3.1).
CONCLUSIONS
In a conflict-affected region of Pakistan, exposure to unregulated treatment with labour-inducing medication is common, and carries great risk for mother and child. Tighter regulatory control of labour-inducing drugs is needed, and enhanced training of the mid-level cadres of healthcare workers is required

Although user fees are a common form of healthcare financing in resource-poor countries, there is growing consensus that their use compromises health service utilisation and population health. Between 2003 and 2006, Médecins sans Frontières (MSF) conducted population-based surveys in Burundi, Sierra Leone, Democratic Republic of Congo, Chad, Haiti and Mali to determine the impact of user fees on healthcare-seeking behaviour and access. For general and disease-specific conditions, MSF also measured the impact of (i) reduced payment systems in Chad, Mali, Haiti and Burundi and (ii) user fee abolition for certain population groups in Burundi and Mali. User fees were found to result in low utilisation of public health facilities, exclusion from health care and exacerbation of impoverishment, forcing many to seek alternative care. Financial barriers affected 30-60% of people requiring health care. Exemption systems targeting vulnerable individuals proved ineffective, benefiting only 1-3.5% of populations. Alternative payment systems, requiring 'modest' fees from users (e.g. low flat fees), did not adequately improve coverage of essential health needs, especially for the poorest and most vulnerable. Conversely, user fee abolition for large population groups led to rapid increases in utilisation of health services and coverage of essential healthcare needs. Abolition of user fees appears crucial in helping to reduce existing barriers to health care. The challenge for health authorities and donor agencies is around working creatively to remove the fees while addressing the financial consequences of improved access and providing quality care.

BACKGROUND
In 2015, more than 1 million refugees arrived in Europe. During their travels, refugees often face harsh conditions, violence and torture in transit countries, but there is a lack of quantitative evidence on their experiences. We present the results of a retrospective survey among refugees in the 'Jungle' of Calais, France, to document their health problems and the violence they endured during their journeys.
METHODS
We conducted a cross-sectional population-based survey in November and December 2015. The sample size was set at 402 individuals, and geospatial simple random sampling was used. We collected data on demographics, routes travelled, health status, violence and future plans.
RESULTS
Departures from the country of origin increased beginning in September 2015. Sixty-one percent of respondents reported having at least one health problem, especially while in Calais. Overall, 65.6% (95% CI 60.3-70.6) experienced at least one violent event en route; 81.5% of refugees wanted to go to the UK.
CONCLUSIONS
This first quantitative survey conducted among refugees in Europe provides important socio-demographic data on refugees living in Calais and describes the high rate of violence they encountered during their journeys. Similar documentation should be repeated throughout Europe in order to better respond to the needs of this vulnerable population.
