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.

BACKGROUND
In East Africa, fishing communities are considered most-at-risk populations for the acquisition of HIV. We estimated HIV prevalence and assessed progress towards the UNAIDS 90–90-90 targets along the HIV treatment cascade in 12 fishing communities surrounding Lakes Edward and George, Uganda.
METHODS
We conducted a cross-sectional household-based survey between September and November 2016. All adults between 15 and 69 years old were eligible to participate. Children below 15 years old were eligible for HIV testing if either parent was HIV-positive. Viral load testing was done for all HIV-infected individuals. Logistic regression models adjusted for sociodemographic-behavioral variables were used to assess the association between occupation and HIV positivity.
RESULTS
Overall, 1738 adults (959 women, 779 men) and 148 children were included. Adult inclusion rate was 96.0%. Of the men, 58% reported to be fishermen. The HIV-prevalence among adults was 17.5% (95%CI: 15.8–19.4) and 6.1% (95%CI: 3.1–11.4) among HIV-exposed children. HIV prevalence was higher among women than among men (20.9% vs. 13.5%, p < 0.001). Among men, fishermen had a higher HIV prevalence (18.7%; 95%CI: 15.1–22.3) and a higher risk of being HIV-positive (aOR: 4.2; 95%CI: 2.0–9.1) than men of other occupations (p < 0.001). Progress towards the UNAIDS 90–90-90 targets was as follows: 86.5% (95%CI: 82.3–90.1%) of the HIV-positive participants were diagnosed, 98.7% (95%CI: 96.1–99.6%) of those aware were on antiretroviral therapy (ART), and 87.3% (95%CI: 82.3–91.0%) of those on ART were virally suppressed. Overall, 73% of all HIV-positive individuals were virally suppressed. Viral suppression was lower among individuals 15–24 years (45.5%) than among those 25–44 years (74.0%) and 45–69 years (85.0%), p < 0.001. Fishermen did not to have significant differences in the HIV cascade of care compared to men with other occupations.
CONCLUSIONS
HIV prevalence was high in these fishing communities, particularly among women and fishermen. Important progress has been made along the HIV treatment cascade, and the UNAIDS goal for viral suppression in population was achieved. However, gaps remain and HIV care strategies focusing on young people are urgently needed. HIV preventive interventions should target particularly women, young people and fishermen though HIV preventive and care services should remain available to the whole fishing communities.

Background: Expanding access to antiretroviral therapy (ART) in sub-Saharan Africa requires implementation of alternative care delivery models to traditional physician-centered approaches. This longitudinal analysis compares outcomes of patients initiated on antiretroviral therapy (ART) by non-physician and physician providers. Methods: Adults (≥15 years) initiating ART between September 2007 and March 2010, and with >1 follow-up visit were included and classified according to the proportion of clinical visits performed by nurses or by clinical officers(≥80% of visits). Multivariable Poisson models were used to compare 2-year program attrition (mortality and lost to follow-up) and mortality by type of provider. In sensitivity analyses only patients with less severe disease were included. Results: A total of 10,112 patients contributed 14,012 person-years to the analysis: 3386 (33.5%) in the clinical officer group, 1901 (18.8%) in the nurse care group and 4825 (47.7%) in the mixed care group. Overall 2-year program retention was 81.8%. Attrition was lower in the mixed care and higher in the clinical officer group, compared to the nurse group (adjusted incidence rate ratio [aIRR]=0.54, 95%CI 0.45-0.65; and aIRR=3.03, 95%CI 2.56-3.59,respectively). While patients initiated on ART by clinical officers in the mixed care group had lower attrition(aIRR=0.36, 95%CI 0.29-0.44) than those in the overall nurse care group; no differences in attrition were found between patients initiated on ART by nurses in the mixed care group and those included in the nurse group (aIRR=1.18, 95%CI 0.95-1.47). Two-year mortality estimates were aIRR=0.72, 95%CI 0.49-1.09 and aIRR=5.04,95%CI 3.56-7.15, respectively. Slightly higher estimates were observed when analyses were restricted to patients with less severe disease. Conclusion: The findings of this study support the use of a mixed care model with well trained and regularly supervised nurses and medical assistants to provide HIV care in countries with high HIV prevalence.

Age and gender disparities within the HIV cascade of care are critical to focus interventions efficiently. We assessed gender-age groups at the highest probability of unfavorable outcomes in the HIV cascade in five HIV prevalent settings. We performed pooled data analyses from population-based surveys conducted in Kenya, South Africa, Malawi and Zimbabwe between 2012 and 2016. Individuals aged 15–59 years were eligible. Participants were tested for HIV and viral load was measured. The HIV cascade outcomes and the probability of being undiagnosed, untreated among those diagnosed, and virally unsuppressed (≥1,000 copies/mL) among those treated were assessed for several age-gender groups. Among 26,743 participants, 5,221 (19.5%) were HIV-positive (69.9% women, median age 36 years). Of them, 72.8% were previously diagnosed and 56.7% virally suppressed (88.5% among those treated). Among individuals 15–24 years, 51.5% were diagnosed vs 83.0% among 45–59 years, p<0.001. Among 15–24 years diagnosed, 60.6% were treated vs 86.5% among 45–59 years, p<0.001. Among 15–24 years treated, 77.9% were virally suppressed vs 92.0% among 45–59 years, p<0.001. Among all HIV-positive, viral suppression was 32.9% in 15–24 years, 47.9% in 25–34 years, 64.9% in 35–44 years, 70.6% in 45–59 years. Men were less diagnosed than women (65.2% vs 76.0%, p<0.001). Treatment among diagnosed and viral suppression among treated was not different by gender. Compared to women 45–59 years, young people had a higher probability of being undiagnosed (men 15–24 years OR: 37.9, women 15–24 years OR: 12.2), untreated (men 15–24 years OR:2.2, women 15–24 years OR: 5.7) and virally unsuppressed (men 15–24 years OR: 1.6, women 15–24 years OR: 6.6). In these five Eastern and Southern Africa settings, adolescents and young adults had the largest gaps in the HIV cascade. They were less diagnosed, treated, and virally suppressed, than older counterparts. Targeted preventive, testing and treating interventions should be scaled-up.

Accurately identifying individuals who are on antiretroviral therapy (ART) is important to determine ART coverage and proportion on ART who are virally suppressed. ART is also included in recent infection testing algorithms used to estimate incidence. We compared estimates of ART coverage, viral load suppression rates and HIV incidence using ART self-report and detection of antiretroviral (ARV) drugs and we identified factors associated with discordance between the methods.
