La importancia de los derechos humanos en la respuesta ante el avance de la epidemia de la infección por el virus del Zika

[RESUMEN]. A fines del 2015, un aumento del número de lactantes nacidos con microcefalia en comunidades pobres del nordeste de Brasil dio lugar a una investigación en la cual se determinó que la causa era la infección prenatal por el virus del Zika. Actualmente, este virus circula en 69 países y ha afectado embarazos en 29 países. Los funcionarios de salud pública, los responsables de las políticas y los organismos internacionales están considerando intervenciones para abordar las consecuencias para la salud de la epidemia de la infección por el virus del Zika. Hasta la fecha, las respuestas de salud pública se han centrado en la erradicación de mosquitos vectores, los servicios de salud sexual y reproductiva, el conocimiento y la tecnología (como las pruebas de diagnóstico y el desarrollo de vacunas), y la preparación del sistema de salud. En este artículo resumimos las respuestas que tuvieron lugar hasta la fecha y aplicamos principios de derechos humanos y otros conexos, como la no discriminación, la participación, el contexto jurídico y de políticas, y la rendición de cuentas para detectar las deficiencias y ofrecer sugerencias de respuestas más equitativas, eficaces y sostenibles.

[ABSTRACT]. In late 2015, an increase in the number of infants born with microcephaly in poor communities in northeast Brazil prompted investigation of antenatal Zika infection as the cause. Zika now circulates in 69 countries, and has affected pregnancies of women in 29 countries. Public health officials, policymakers, and international organizations are considering interventions to address health consequences of the Zika epidemic. To date, public health responses have focused on mosquito vector eradication, sexual and reproductive health services, knowledge and technology including diagnostic test and vaccine development, and health system preparedness. We summarize responses to date and apply human rights and related principles including nondiscrimination, participation, the legal and policy context, and accountability to identify shortcomings and to offer suggestions for more equitable, effective, and sustainable Zika responses.

Barriers along the care cascade of HIV-infected men in a large urban center of Brazil.

Global and national HIV/AIDS policies utilize the care cascade to emphasize the importance of continued engagement in HIV services from diagnosis to viral suppression. Several studies have documented barriers that men experience in accessing services at specific stages of care, but few have analyzed how these barriers operate along the care cascade. Brazil offers a unique setting for analyzing barriers to HIV care because it is a middle-income country with a large HIV epidemic and free, universal access to HIV/AIDS services. Semi-structured interviews were conducted in 2011 with HIV-infected men (n = 25) receiving care at the only HIV/AIDS state reference center in Salvador, Brazil, the third largest city in the country. Interviews were transcribed and coded for analysis. Researchers identified barriers to services along the care cascade: health service-related obstacles (poor-quality care, lengthy wait times, and drug supply problems); psychosocial and emotional challenges (fear of disclosure and difficulty accepting HIV diagnosis); indirect costs (transportation and absenteeism at work or school); low perceived risk of HIV; and toxicity and complexity of antiretroviral drug (ARV) regimens. The stages of the care cascade interrupted by each barrier were also identified. Most barriers affected multiple, and often all, stages of care, while toxicity and complexity of ARV regimens was only present at a single care stage. Efforts to eliminate more prevalent barriers have the potential to improve care continuity at multiple stages. Going forward, assessing the relative impact of barriers along one's entire care trajectory can help tailor improvements in service provision, facilitate achievement of viral suppression, and improve access to life-saving testing, treatment, and care.

Quality, not just quantity: lessons learned from HIV testing in Salvador, Brazil.

Studies have demonstrated that an early HIV diagnosis is a critical first step towards continued engagement in care. We examined HIV testing experiences in Salvador, Brazil, to understand how a focus on quality services can inform service provision more generally in the post-2015 global health agenda. Seventeen semi-structured interviews were conducted with HIV-positive pregnant women in Salvador, a large urban centre of north-east Brazil. Interviews were transcribed, translated and coded for analysis. Deductive codes confirmed factors identified in the literature review. Inductive codes highlighted new factors emerging from the initial coding. 'Quality' was defined according to global and national guidelines as HIV testing with informed and voluntary consent, counselling and confidentiality (3Cs). No pregnant woman experienced all elements of the 3Cs. Three women did not experience any informed and voluntary consent, counselling or confidentiality. Few women provided consent overall and none received pre-test counselling. Post-test counselling and confidentiality of services were more consistently provided. This study suggests that testing in Salvador - the third-largest city in the country - is not of the quality called for by global and national guidelines, despite the fact that HIV testing is being routinely provided for HIV-positive pregnant women in Brazil. Going forward, additional clarity around the 3Cs is necessary to improve how the quality, not just the quantity, of HIV services is measured.

Contemplating abortion: HIV-positive women's decision to terminate pregnancy.

Research on pregnancy termination largely assumes HIV status is the only reason why HIV-positive women contemplate abortion. As antiretroviral treatment (ART) becomes increasingly available and women are living longer, healthier lives, the time has come to consider the influence of other factors on HIV-positive women's reproductive decision-making. Because ART has been free and universally available to Brazilians for more than two decades, Brazil provides a unique context in which to explore these issues. A total of 25 semi-structured interviews exploring women's pregnancy termination decision-making were conducted with women receiving care at the Reference Centre for HIV/AIDS in Salvador, Brazil. Interviews were transcribed, translated into English and coded for analysis. HIV played different roles in women's decision-making. In all, 13 HIV-positive women did not consider terminating their pregnancy. Influential factors described by those who did consider terminating their pregnancy included fear of HIV transmission, fear of HIV-related stigma, family size, economic constraints, partner and provider influence, as well as lack of access to pregnancy termination services and abortifacients. For some HIV-positive women in Brazil, HIV can be the only reason to consider terminating a pregnancy, but other factors are significant. A thorough understanding of all variables affecting reproductive decision-making is necessary for enhancing services and policies and better meeting the needs and rights of HIV-positive women.

"I did not feel like a mother": the success and remaining challenges to exclusive formula feeding among HIV-positive women in Brazil.

Exclusive and safe formula feeding can eliminate the risk of vertical HIV transmission due to breastfeeding. Therefore, many countries advise all HIV-positive women to avoid breastfeeding their infants. However, little research explores the experiences of women attempting to exclusively formula feed in countries with free and universal access to highly active antiretroviral therapy (HAART). This article examines the success of Brazil in supporting HIV-positive women as engage in exclusive formula feeding (EFF). We conducted in-depth interviews with 30 HIV-positive women receiving care at the primary facility for HIV/AIDS in Salvador, Brazil about their attitudes and practices related to EFF as well as challenges with adhering to EFF. All interviews were recorded, professionally transcribed and translated, and then analyzed. Our results showed that one woman reported both breastfeeding and formula feeding her infant; all others reported EFF. Postpartum counseling regarding the risk of HIV transmission through breastfeeding was the primary motivation for EFF. Challenges included difficulty reconciling their perceptions that breastfeeding is an important maternal responsibility, trouble accepting that breastfeeding can cause potential to harm their infants, confronting HIV-related stigma associated with EFF, and unexpected financial burdens due to EFF. We conclude that HIV-positive women adhered to national guidelines recommending EFF; this phenomenon has likely contributed to declining rates of vertical transmission in Brazil. Despite this success, many women experienced challenges with EFF. Greater support services may enhance Brazil's success in empowering HIV-positive women and eliminating vertical HIV transmission via breastfeeding.

Engaging patients via mobile phone technology to assist follow-up after hospitalization in Quito, Ecuador.

OBJECTIVE: Disease management following hospital discharge is difficult in most low-resourced areas, posing a major obstacle to health equity. Although mobile phones are a ubiquitous and promising technology to facilitate healthcare access, few studies have tested the acceptability and feasibility of patients themselves using the devices for assisting linkages to healthcare services. We hypothesized that patients would use mobile phones to help manage postdischarge problems, if given a communication protocol. We developed a mobile phone-based program and investigated its acceptability and feasibility as a method of delivering posthospitalization care. SUBJECTS AND METHODS: A consecutive cohort of adult patients in a public hospital in Quito, Ecuador was enrolled over a 1-month period. A hospital-based nurse relayed patients' discharge instructions to a community-based nurse. Patients corresponded with this nurse via text messaging and phone calls according to a protocol to initiate and participate in follow-up. RESULTS: Eighty-nine percent of eligible patients participated. Ninety-seven percent of participants completed at least one contact with the nurse; 81% initiated contact themselves. Nurses completed 262 contacts with 32 patients, clarifying discharge instructions, providing preventive education, and facilitating clinic appointments. By this method, 87% of patients were successfully linked to follow-up appointments. CONCLUSIONS: High levels of patient participation and successful delivery of follow-up services indicate the mobile phone program's acceptability and feasibility for facilitating posthospitalization follow-up. Patients actively used mobile phones to interact with nurses, enabling the provision of posthospitalization medical advice and facilitate community-based care via mobile phone.
