Association of same-sex criminalisation laws and national HIV policies with HIV testing in African MSM: an ecological single-level and multilevel cross-sectional study of sub-Saharan African countries.

BACKGROUND: HIV incidence among men who have sex with men (MSM) in sub-Saharan Africa (SSA) remains high compared with the general population. Many countries in the region still criminalise consensual homosexual relationships, and some are yet to adopt WHO-recommended interventions for MSM into national HIV policies. This study examines how HIV testing of adult MSM in SSA varies according to the legal climate and presence of targeted HIV policy using data from the cross-sectional 2019 Global LGBTI Internet Survey study. METHODS: Using data from 3191 MSM in 44 SSA countries, we assessed associations of legal climate and HIV policy with ever and recent HIV testing using linear ecological and logistic multilevel analyses. From the single-level analysis, we can compare our findings to previously reported data, then, extending to a two-level multilevel analysis, we account for the hierarchical structure of the population and simultaneously adjust for differences in context and composition in each country. We then test the sensitivity of our analyses to excluding countries from the model. RESULTS: We find evidence that legalised same-sex relationships were associated with increased odds of ever testing (OR=2.00, 95% CI 1.04, 3.82) in multilevel analyses. We also find evidence of an association of targeted HIV policies with increased odds of ever testing (OR=2.49, 95% CI 1.12, 5.52). We did not find evidence of an association of the legal climate (OR=1.01, 95% CI 0.69, 1.46) and targeted HIV policies (OR=1.26, 95% CI 0.78, 2.04) with recent testing. CONCLUSIONS: This study suggests elimination of discriminatory laws and policies might be important for increasing HIV status awareness of MSM, an important first step in epidemic control. Additionally, we highlight heterogeneity between South Africa and other SSA countries, which has implications for studying SSA countries as a homogeneous group.

Is Internalised Homonegativity associated with HIV testing and HIV risk behaviours of men who have sex with men: a multilevel cross-sectional study of sub-Saharan African countries.

OBJECTIVES: This study assessed the associations of Internalised Homonegativity (IH) with HIV testing and risk behaviours of adult men who have sex with men (MSM) in sub-Saharan Africa (SSA) and effect modification by the legal climate. DESIGN: We used data from the cross-sectional 2019 Global Lesbian, Gay, Bisexual, Transgender and Intersex (LGBTI+) Internet survey study. SETTING AND PARTICIPANTS: Overall, the 2019 Global LGBTI Internet Survey collected data from 46 SSA countries. In this secondary analysis, we included data from 3191 MSM in 44 SSA countries as there were no eligible MSM responses in the 2 countries excluded. OUTCOME MEASURES: Our response variables were self-reported binary indicators of ever tested for HIV, recently tested in the past 6 months (from those who reported ever testing), transactional sex (paying for and being paid for sex in the past 12 months), and unprotected anal sex (that is without a condom or pre-exposure prohylaxis (PrEP)) with a non-steady partner (in the past 3 months). RESULTS: Our findings showed high levels of IH (range 1-7) in MSM across SSA (mean (SD)=5.3 (1.36)). We found that MSM with higher IH levels were more likely to have ever (adjusted OR (aOR) 1.18, 95% CI 1.03 to 1.35) and recently tested (aOR 1.19, 95% CI 1.07 to 1.32) but no evidence of an association with paying for sex (aOR 1.00, 95% CI 0.89 to 1.12), selling sex (aOR 1.06, 95% CI 0.95 to 1.20) and unprotected sex (aOR 0.99, 95% CI 0.89 to 1.09). However, we observed that a favourable legal climate modifies the associations of IH and paying for sex (aOR 0.75, 95% CI 0.60 to 0.94). Increasing levels of IH had a negative association with paying for sex in countries where same-sex relationships are legal. We found no associations of IH with unprotected anal sex in the population surveyed. CONCLUSIONS: We confirm that IH is widespread across SSA but in countries that legalise same-sex relationships, MSM were less likely to engage in transactional sex compared with those in countries where homosexuality is criminalised.

Assessment and determinants of depression and anxiety on a global sample of sexual and gender diverse people at high risk of HIV: a public health approach.

BACKGROUND: Sexual and gender diverse people face intersecting factors affecting their well-being and livelihood. These include homophobic reactions, stigma or discrimination at the workplace and in healthcare facilities, economic vulnerability, lack of social support, and HIV. This study aimed to examine the association between such factors and symptoms of anxiety and depression among sexual and gender diverse people. METHODS: This study is based on a sample of 108,389 gay, bisexual, queer and questioning men, and transfeminine people from 161 countries collected through a cross-sectional internet survey. We developed a multinomial logistic regression for each group to study the associations of the above factors at different severity scores for anxiety and depression symptoms. RESULTS: Almost a third (30.3%) of the participants reported experiencing moderate to severe symptoms of anxiety and depression. Higher severity scores were found for transfeminine people (39%), and queer or questioning people (34.8%). Severe symptoms of anxiety and depression were strongly correlated with economic hardship for all groups. Compared to those who are HIV-negative, those living with HIV were more likely to report severe symptoms of anxiety and depression, and the highest score was among those who do not know their HIV status. Transfeminine people were the most exposed group, with more than 80% higher risk for those living with HIV suffering from anxiety and depression. Finally, homophobic reactions were strongly associated with anxiety and depression. The relative risk of severe anxiety and depression was 3.47 times higher for transfeminine people facing transphobic reactions than those with no symptoms. Moreover, anxiety and depression correlate with stigma or discrimination in the workplace and healthcare facilities. CONCLUSIONS: The strong association between the severity of anxiety and depression, and socioeconomic inequality and HIV status highlights the need for concrete actions to meet the United Nations' pledge to end inequalities faced by communities and people affected by HIV. Moreover, the association between stigma or discrimination and anxiety and depression among sexual and gender diverse people is alarming. There is a need for bold structural public health interventions, particularly for transfeminine, queer and questioning people who represent three communities under the radar of national HIV programmes.

The health inequity and socioeconomic inequality faced by adolescent girls and women on the move living with or at high risk of HIV infection, during the COVID-19 pandemic in Nigeria.

BACKGROUND: We assessed if women and girls on the move living with or at high risk of HIV faced increased health inequity and socioeconomic inequalities during the COVID-19 pandemic compared with other vulnerable women and girls. METHODS: We used data collected through a survey conducted in Nigeria between June and October 2021. Women and girls living with or at risk of HIV were recruited voluntarily, using a combination of venue-based and snowball sampling. We performed multivariable logistic regression models per mobility and HIV status to determine associations between health inequity, socioeconomic inequalities and macrosocial characteristics. FINDINGS: There were 3442 participants, of which 700 were on the move. We found no statistical difference between HIV-negative women and girls on the move and those not on the move. On the opposite, we found substantial differences in health inequity and socioeconomic inequalities between women and girls on the move living with HIV and those not on the move living with HIV. There are very strong associations between being a woman or girl on the move living with HIV and facing economic precarity (aOR 6.08, 95% CI 1.94 to 19.03), food insecurity (aOR 5.96, 95% CI 2.16 to 16.50) and experiencing more gender-based violence since COVID-19 started (aOR 5.61, 95% CI 3.01 to 10.47). INTERPRETATION: Being a woman or girl on the move and living with HIV compound increased health and socioeconomic vulnerabilities. The COVID-19 crisis seems to have exacerbated inequalities and gender-based violence. These findings call for more feminist interventions to protect women on the move living with HIV during health crises.

Socioeconomic inequality, health inequity and well-being of transgender people during the COVID-19 pandemic in Nigeria.

BACKGROUND: We aimed to explore socioeconomic inequality, health inequity, and the well-being of transgender people during the COVID-19 crisis in Nigeria. METHODS: Between June and December 2021, a cross-sectional survey was conducted collaboratively with community-based organisations in Nigeria. Participants living with or at risk of HIV were recruited voluntarily, online and face-to-face, using a combination of venue-based and snowball sampling. We assessed the association between gender identity (transgender and vulnerable cisgender women), and (i) socioeconomic inequality measured with socioeconomic status, social status, economic vulnerability, macrosocial vulnerability; (ii) health inequity measured with self-assessment of health, recency of HIV test, access to HIV and sexual and reproductive health services, gender-affirming care, financial and non-financial barriers to accessing health services; and (iii) well-being, measured with gender-based violence, mental health, psychoeconomic preferences. We used multivariable logistic regressions and controlled for interactions and confounders. RESULTS: There were 4072 participants; 62% were under 30, and 47% reported living with HIV. One in ten (11.9%; n = 485) was transgender, and 56.5% reported living with HIV. Compared to vulnerable cisgender women, the results showed significantly higher odds (aOR:3.80) of disruption in accessing HIV services in transgender participants; gender-based violence (aOR:2.63); severe (aOR:2.28) symptoms of anxiety and depression. Among the barriers to accessing health and HIV services, transgender had three-time higher odds of reporting additional non-official fees compared to vulnerable cisgender women. The disclosure of their gender identity or sexual orientation was the most important non-financial barrier to accessing health services (aOR:3.16). Transgender participants faced higher housing insecurity (aOR: 1.35) and lower odds of using drugs (aOR:0.48). Importantly, they are more likely to have performed a recent HIV test and less likely to not know their HIV status (aOR:0.38) compared to vulnerable cisgender women. CONCLUSIONS: Socioeconomic inequality, health and well-being inequity in transgender people appear to be exacerbated by the COVID-19 pandemic in Nigeria. Interventions are necessary to mitigate socioeconomic challenges, address structural inequality, and ensure equitable access to health services to meet the Sustainable Development Goals for transgender people.

Impact of COVID-19 public health responses on income, food security and health services among key and vulnerable women in South Africa.

Globally, COVID-19 has impacted lives and livelihoods. Women living with HIV and/or at high risk of acquiring HIV are socially and economically vulnerable. Less is known of the impact of COVID-19 public health responses on women from key and vulnerable populations. The purpose of this cross-sectional survey conducted in four South African provinces with a high burden of HIV and COVID-19 from September to November 2021 was to advance understanding of the socio-economic and health care access impact of COVID-19 on women living with HIV or at high risk of acquiring HIV. A total of 2 812 women >15 years old completed the survey. Approximately 31% reported a decrease in income since the start of the pandemic, and 43% an increase in food insecurity. Among those accessing health services, 37% and 36% reported that COVID-19 had impacted their access to HIV and family planning services respectively. Economic and service disruptions were enhanced by living in informal housing, urbanisation and being in the Western Cape. Food insecurity was increased by being a migrant, having fewer people contributing to the household, having children and experience of gender-based violence. Family planning service disruptions were greater for sex workers and having fewer people contributing to the household. These differentiated impacts on income, food security, access to HIV and family planning services were mediated by age, housing, social cohesion, employment and household income, highlighting the need for improved structural and systemic interventions to reduce the vulnerability of women living with HIV or at high risk of acquiring HIV.

The effects of COVID-19 on food insecurity, financial vulnerability and housing insecurity among women and girls living with or at risk of HIV in Nigeria.

Aim: Women and girls living with or at high risk of acquiring HIV (WGL&RHIV) in Africa are economically vulnerable. This study aims to advance understanding of the economic impact of COVID-19 on WGL&RHIV and to identify the factors associated with this insecurity.Methods: Data were collected from a cross-sectional survey conducted among a convenience sample of WGL&RHIV in Nigeria between May and September 2021. Logistic regressions enabled the study of the role of HIV status, mental health and macrosocial characteristics (people with disability, transgender women, sex workers, persons engaged in transactional sex, substance users, and people on the move) on economic vulnerability, measured by food, financial and housing insecurity, since the COVID-19 pandemic began. The model accounted for the possible interactions between the macrosocial characteristics and controlled for confounders.Results: There were 3 313 (76.1%) of 4 355 respondents facing food insecurity, 3 664 (83.6%) of 4 385 with financial vulnerability and 1 282 (36.2%) of 3 544 with housing insecurity. Being a member of the key and vulnerable groups was strongly associated with food insecurity, financial vulnerability and housing insecurity, regardless of HIV serostatus. For example, WGL&RHIV engaging in transactional sex were more than four times more likely (aOR 4.42; 95% CI 2.57-7.59) to face housing insecurity and more than twice more likely to face food insecurity (aOR 2.47, 95% CI 1.35-4.52) and financial vulnerability (aOR 2.87, 95% CI 1.39-5.93). This economic vulnerability may reduce their negotiating power for safer sex or the use of HIV prevention methods, exposing them to increased risks of HIV infection. Poor mental health was also associated with the three forms of economic vulnerability.Conclusions: As the long-term impact of the COVID-19 crisis on African economies unfolds, HIV programmes at the country level must include economic vulnerability and mental unwellness mitigation activities for WGL&RHIV.

Associations between COVID-19 vaccine hesitancy and the experience of violence among women and girls living with and at risk of HIV in Nigeria.

Aim: Women and girls living with and at high risk of HIV (WGL&RHIV) had an increased risk for gender-based violence (GBV) during COVID-19. The study aimed to assess the associations between vaccine hesitancy and GBV, HIV status and psychological distress among these vulnerable women and girls in Nigeria.Methods: This cross-sectional study collected data from WGL&RHIV in 10 states in Nigeria between June and October 2021. The dependent variable was vaccine hesitancy. The independent variables were the experience of physical, sexual, economic and emotional GBV, HIV status and psychological distress during the COVID-19 pandemic. We conducted a multivariable logistics regression analysis to test the associations between vaccine hesitancy and the independent variables and covariates.Results: Among the 3 431 participants, 1 015 (22.8%) were not willing to be vaccinated against COVID-19. Not knowing or willing to disclose HIV status (aOR 1.40) and having mild (aOR 1.36) and moderate (aOR 1.38) symptoms of anxiety and depression were significantly associated with higher odds of vaccine hesitancy. Being a survivor of intimate partner physical violence (aOR 5.76), non-intimate partner sexual violence (aOR 3.41), as well as emotional abuse (aOR 1.55) were significantly associated with respectively more than five, three and one and half times higher odds of vaccine hesitancy. One positive outcome is that HIV-positive women and girls appeared to be more likely to get the COVID-19 vaccine when available.Conclusions: Sexual and gender-based violence, low socio-economic status, psychological distress and an unknown HIV status are essential determinants of COVID-19 vaccine hesitancy among vulnerable women and girls in Nigeria. National authorities and civil society organisations need to better integrate COVID-19 mitigation activities with HIV and gender-based violence interventions through a more feminist approach that promotes gender equality and the empowerment of women and girls in all their diversity for better access to health services.

Factors associated with poor access to HIV and sexual and reproductive health services in Nigeria for women and girls living with HIV during the COVID-19 pandemic.

Aim: To determine the proportion of women and girls living with HIV (WGLHIV) who had poor access to HIV, tuberculosis and sexual and reproductive health (SRH) services in Nigeria during the COVID-19 pandemic and associated factors.Methods: This was a cross-sectional study that recruited WGLHIV with six categories of vulnerability (sex work, transactional sex, injecting or using illegal drugs, people on the move, transgender women and people with a disability) through an online survey conducted in ten Nigerian states between june and October 2021. The associations between the limited access to HIV, tuberculosis and SRH services due to COVID-19, the categories of vulnerability and the financial and non-financial barriers to these services were determined using multivariable logistics regression analysis.Results: Over 6 in 10, almost 2 in 10, and almost 4 in 10 WGLHIV had limited access to HIV, tuberculosis and SRH services respectively during the COVID-19 pandemic. Transgender women had 3.59 (95% CI 2.19-5.91) higher odds, women who engaged in sex work had 4.51 (95% CI 2.28-8.42) higher odds, and women who inject or use illegal drugs had 2.39 (95% CI 1.47-32.90) higher odds of facing limited access to sexual and reproductive health services when it was needed. In addition, the direct consequences of the COVID-19 crisis, such as the closure of HIV services and SRH service points, exacerbated pre-existing barriers significantly. Having no money, having to pay additional unofficial fees and the lack of security on the road to the health facility were the barriers with the greatest impact on access to health services.Conclusions: The COVID-19 pandemic had a negative impact on the access of WGLHIV to essential health services. This impact was disproportionately higher for marginalised groups. WGLHIV need non-discriminatory and affordable access to essential health services during the pandemic.

Impact of COVID-19 public health responses on income, food security and health services among key and vulnerable women in South Africa

The effects of COVID-19 on food insecurity, financial vulnerability and housing insecurity among women and girls living with or at risk of HIV in Nigeria

Aim: Women and girls living with or at high risk of acquiring HIV (WGL&RHIV) in Africa are economically vulnerable. This study aims to advance understanding of the economic impact of COVID-19 on WGL&RHIV and to identify the factors associated with this insecurity.Methods: Data were collected from a cross-sectional survey conducted among a convenience sample of WGL&RHIV in Nigeria between May and September 2021.

This economic vulnerability may reduce their negotiating power for safer sex or the use of HIV prevention methods, exposing them to increased risks of HIV infection. Poor mental health was also associated with the three forms of economic vulnerability.Conclusions: As the long-term impact of the COVID-19 crisis on African economies unfolds, HIV programmes at the country level must include economic vulnerability and mental unwellness mitigation activities for WGL&RHIV

Evidence-based policymaking when evidence is incomplete: The case of HIV programme integration.

Jan Hontelez and co-authors discuss the use of different types of evidence to inform HIV program integration.

Integrating HIV services and other health services: A systematic review and meta-analysis.

BACKGROUND: Integration of HIV services with other health services has been proposed as an important strategy to boost the sustainability of the global HIV response. We conducted a systematic and comprehensive synthesis of the existing scientific evidence on the impact of service integration on the HIV care cascade, health outcomes, and cost-effectiveness. METHODS AND FINDINGS: We reviewed the global quantitative empirical evidence on integration published between 1 January 2010 and 10 September 2021. We included experimental and observational studies that featured both an integration intervention and a comparator in our review. Of the 7,118 unique peer-reviewed English-language studies that our search algorithm identified, 114 met all of our selection criteria for data extraction. Most of the studies (90) were conducted in sub-Saharan Africa, primarily in East Africa (55) and Southern Africa (24). The most common forms of integration were (i) HIV testing and counselling added to non-HIV services and (ii) non-HIV services added to antiretroviral therapy (ART). The most commonly integrated non-HIV services were maternal and child healthcare, tuberculosis testing and treatment, primary healthcare, family planning, and sexual and reproductive health services. Values for HIV care cascade outcomes tended to be better in integrated services: uptake of HIV testing and counselling (pooled risk ratio [RR] across 37 studies: 1.67 [95% CI 1.41-1.99], p < 0.001), ART initiation coverage (pooled RR across 19 studies: 1.42 [95% CI 1.16-1.75], p = 0.002), time until ART initiation (pooled RR across 5 studies: 0.45 [95% CI 0.20-1.00], p = 0.050), retention in HIV care (pooled RR across 19 studies: 1.68 [95% CI 1.05-2.69], p = 0.031), and viral suppression (pooled RR across 9 studies: 1.19 [95% CI 1.03-1.37], p = 0.025). Also, treatment success for non-HIV-related diseases and conditions and the uptake of non-HIV services were commonly higher in integrated services. We did not find any significant differences for the following outcomes in our meta-analyses: HIV testing yield, ART adherence, HIV-free survival among infants, and HIV and non-HIV mortality. We could not conduct meta-analyses for several outcomes (HIV infections averted, costs, and cost-effectiveness), because our systematic review did not identify sufficient poolable studies. Study limitations included possible publication bias of studies with significant or favourable findings and comparatively weak evidence from some world regions and on integration of services for key populations in the HIV response. CONCLUSIONS: Integration of HIV services and other health services tends to improve health and health systems outcomes. Despite some scientific limitations, the global evidence shows that service integration can be a valuable strategy to boost the sustainability of the HIV response and contribute to the goal of 'ending AIDS by 2030', while simultaneously supporting progress towards universal health coverage.

Ending AIDS as a public health threat by 2030: Time to reset targets for 2025.

Paul De Lay and co-authors introduce a Collection on the design of targets for ending the AIDS epidemic.

The economic returns of ending the AIDS epidemic as a public health threat.

BACKGROUND: In 2016, countries agreed on a Fast-Track strategy to "end the AIDS epidemic by 2030". The treatment and prevention components of the Fast-Track strategy aim to markedly reduce new HIV infections, AIDS-related deaths and HIV-related discrimination. This study assesses the economic returns of this ambitious strategy. METHODS: We estimated the incremental costs, benefits and economic returns of the Fast-Track scenario in low- and middle-income countries, compared to a counterfactual defined as maintaining coverage of HIV-related services at 2015 levels. The benefits are calculated using the full-income approach, which values both the changes in income and in mortality, and the productivity approach. FINDINGS: The incremental costs of the Fast-Track scenario over the constant scenario for 2017-2030 represent US$86 billion or US$13.69 per capita. The full-income valuation of the incremental benefits of the decrease in mortality amounts to US$88.14 per capita, representing 6.44 times the resources invested for all countries. These returns on investment vary by region, with the largest return in the Asia-Pacific region, followed by Eastern and Southern Africa. Returns using the productivity approach are smaller but ranked similarly across regions. INTERPRETATION: In all regions, the economic and social value of the additional life-years saved by the Fast-Track approach exceeds its incremental costs, implying that this strategy for ending the AIDS epidemic is a sound economic investment.

A socioecological measurement of homophobia for all countries and its public health impact.

Background: Measuring homophobia at country level is important to guide public health policy as reductions in stigma are associated with improved health outcomes among gay men and other men who have sex with men. Methods: We developed a Homophobic Climate Index incorporating institutional and social components of homophobia. Institutional homophobia was based on the level of enforcement of laws that criminalise, protect or recognise same-sex relations. Social homophobia was based on the level of acceptance and justifiability of homosexuality. We estimated the Index for 158 countries and assessed its robustness and validity. Results: Western Europe is the most inclusive region, followed by Latin America. Africa and the Middle East are home to the most homophobic countries with two exceptions: South Africa and Cabo Verde. We found that a 1% decrease in the level of homophobia is associated with a 10% increase in the gross domestic product per capita. Countries whose citizens face gender inequality, human rights abuses, low health expenditures and low life satisfaction are the ones with a higher homophobic climate. Moreover, a 10% increase in the level of homophobia at country level is associated with a 1.7-year loss in life expectancy for males. A higher level of homophobia is associated with increased AIDS-related death among HIV-positive men. Conclusion: The socioecological approach of this index demonstrates the negative social, economic and health consequences of homophobia in low- and middle-income countries. It provides sound evidence for public health policy in favour of the inclusion of sexual minorities.

The macroeconomic consequences of renouncing to universal access to antiretroviral treatment for HIV in Africa: a micro-simulation model.

AIM: Previous economic literature on the cost-effectiveness of antiretroviral treatment (ART) programs has been mainly focused on the microeconomic consequences of alternative use of resources devoted to the fight against the HIV pandemic. We rather aim at forecasting the consequences of alternative scenarios for the macroeconomic performance of countries. METHODS: We used a micro-simulation model based on individuals aged 15-49 selected from nationally representative surveys (DHS for Cameroon, Tanzania and Swaziland) to compare alternative scenarios : 1-freezing of ART programs to current levels of access, 2- universal access (scaling up to 100% coverage by 2015, with two variants defining ART eligibility according to previous or current WHO guidelines). We introduced an "artificial" ageing process by programming methods. Individuals could evolve through different health states: HIV negative, HIV positive (with different stages of the syndrome). Scenarios of ART procurement determine this dynamics. The macroeconomic impact is obtained using sample weights that take into account the resulting age-structure of the population in each scenario and modeling of the consequences on total growth of the economy. RESULTS: Increased levels of ART coverage result in decreasing HIV incidence and related mortality. Universal access to ART has a positive impact on workers' productivity; the evaluations performed for Swaziland and Cameroon show that universal access would imply net cost-savings at the scale of the society, when the full macroeconomic consequences are introduced in the calculations. In Tanzania, ART access programs imply a net cost for the economy, but 70% of costs are covered by GDP gains at the 2034 horizon, even in the extended coverage option promoted by WHO guidelines initiating ART at levels of 350 cc/mm(3) CD4 cell counts. CONCLUSION: Universal Access ART scaling-up strategies, which are more costly in the short term, remain the best economic choice in the long term. Renouncing or significantly delaying the achievement of this goal, due to "legitimate" short term budgetary constraints would be a misguided choice.

Macroeconomic impact of HIV: the need for better modelling.

PURPOSE OF REVIEW: To critically evaluate the recent literature on macroeconomic repercussions of the HIV pandemic and the response to it. The review focuses on the impacts of HIV through both its health consequences and its impact on the accumulation of human capital. RECENT FINDINGS: So far, most studies have found a moderate impact of the HIV epidemic on macroeconomic growth. However, recent studies tend to emphasize the fact that HIV undermines human capital and implies a long-term detriment for economic development. Availability of data from Demographic and Health Surveys offers opportunities for better understanding the relationship between the HIV epidemic and economic growth through pathways linking its microeconomic and macroeconomic impacts. SUMMARY: The macroeconomic impact of HIV observed so far appears moderate. Our analysis of recent literature, however, points out three important issues that may have been previously underestimated. First, the most important effects may occur in the longer run, through changes in the accumulation of human capital. Second, aggregate impact often masks an unequal impact among different economic groups. Third, the empirical evidence on which current macroeconomic models are based remains weak, in particular in the way it takes into account responses to HIV at the households' level. Microsimulation models and the recently increasing availability of robust datasets at households' level offer promising opportunities to address these issues.
