Although awareness of the Zika virus has existed since the 1950s, only recently has it attracted the interest of the international community. In 2015 and 2016, the virus spread throughout Brazil and suspicions on the possible relation between parallel increases in neurological disorders and the infection arose. By November 2015, this concern had developed into a National Public Health Emergency. On February 1, 2016, WHO formally declared its suspicion that this was a Public Health Emergency of International Concern (PHEIC), and sent a response in accordance with International Health Regulations (2005). Zika is present in almost all South American countries, and PAHO/WHO, Unasur, and Mercosur are developing responsive actions to the epidemic. The aim of this article is to present a critical analysis of the regional South American and Brazilian responses of February through September 2016, in respect of this PHEIC announcement, utilizing qualitative methodologies via bibliographical examination and document analysis. In this context, the PAHO/WHO played a prominent role as compared with the other organizations. Moreover, the political environment of the region also played a major role in the instability of both Mercosur and Unasur, which could impact the capacity and effectiveness of the response.
Infection with the zika virus had a great impact not only on pregnant women and newborns, but also on public health, on popular ideas about Aedes aegypti and with respect to women's social rights. The objective of this paper is to identify this impact and the historical, social and health changes of the disease and the legacy of the zika virus. Interventions by researchers from different specialties foster conditions for more comprehensive investigations into future epidemic threats in Brazil and Latin America. This dialogue took place after the seminar "Aedes aegypti: past and future health emergencies," organized by the Casa de Oswaldo Cruz, when we talked with some speakers and other leading researchers about the history and challenges of Aedes aegypti and zika.
La estrategia institucional de propagación de la Covid-19 implementada por el gobierno federal brasileño es una expresión radical del neoliberalismo en el campo de la salud, definida como neoliberalismo epidemiológico. Esta promoción de la inmunización masiva por contagio, considerada científicamente equivocada y éticamente inaceptable, se opone de manera frontal a las recomendaciones de la Organización Mundial de la Salud (oms). La renuncia al liderazgo pretérito de Brasil en temas de salud global y de cooperación regional en salud se explica también por el carácter ideológico de su nueva política exterior y a la militarización del Ministerio de la Salud.
