The global scientific research response to the public health emergency of Zika virus infection.

BACKGROUND: Science studies have been a field of research for different knowledge areas, and they have been successfully used to analyse the construction of scientific knowledge, practice and dissemination. In this study, we aimed to verify how the Zika epidemic has moulded the scientific articles published worldwide by analysing international collaborations and the knowledge landscape through time, as well as research topics and country involvement. METHODOLOGY: We searched the Web of Science (WoS), Scopus and PubMed for studies published up to 31st December 2018 on Zika using the search terms "zika", "zkv" or "zikv". We analysed the scientific production regarding which countries have published the most, on which topics, as well as country level collaboration. We performed a scientometric analysis of research on Zika focusing on knowledge mapping and the scientific research path over time and space. FINDINGS: We found two well defined research areas divided into three subtopics accounting for six clusters. With regard to country analysis, the USA and Brazil were the countries with the highest numbers of publications on Zika. China entered as a new player focusing on specific research areas. When we took into consideration the epidemics and reported cases, Brazil and France were the leading research countries on related topics. As for international collaboration, the USA followed by England and France stand out as the main hubs. The research areas most published included public health-related topics from 2015 until the very beginning of 2016, followed by an increase in topics related to the clinical aspects of the disease in 2016 and the emergence of laboratory research in 2017/2018. CONCLUSIONS: Mapping the response to Zika, a public health emergency, demonstrated a clear pattern of the participation of countries in the scientific advances. The pattern of knowledge production found in this study represented varying country perspectives, research capacity and interests based first on their level of exposure to the epidemic and second on their financial positions regarding science.

SEASONAL DISTRIBUTION OF MALARIA VECTORS (DIPTERA: CULICIDAE) IN RURAL LOCALITIES OF PORTO VELHO, RONDÔNIA, BRAZILIAN AMAZON.

We conducted a survey of the malaria vectors in an area where a power line had been constructed, between the municipalities of Porto Velho and Rio Branco, in the states of Rondônia and Acre, respectively. The present paper relates to the results of the survey of Anopheles fauna conducted in the state of Rondônia. Mosquito field collections were performed in six villages along the federal highway BR 364 in the municipality of Porto Velho, namely Porto Velho, Jaci Paraná, Mutum Paraná, Vila Abunã, Vista Alegre do Abunã, and Extrema. Mosquito captures were performed at three distinct sites in each locality during the months of February, July, and October 2011 using a protected human-landing catch method; outdoor and indoor captures were conducted simultaneously at each site for six hours. In the six sampled areas, we captured 2,185 mosquitoes belonging to seven Anopheles species. Of these specimens, 95.1% consisted of Anopheles darlingi, 1.8% An. triannulatus l.s., 1.7% An. deaneorum, 0.8% An. konderi l.s., 0.4 An. braziliensis, 0.1% An. albitarsis l.s., and 0.1% An. benarrochi. An. darlingi was the only species found in all localities; the remaining species occurred in sites with specific characteristics.

Foi realizado levantamento de vetores de malária na área que compreende a construção da linha de transmissão entre os municípios de Porto Velho e Rio Branco, estados de Rondônia e Acre, respectivamente. Os dados aqui apresentados mostram os resultados do levantamento da fauna dos Anopheles realizado em Rondônia. As capturas foram realizadas no município de Porto Velho em seis aglomerados populacionais ao longo da rodovia federal BR 364, denominados Porto Velho, Jaci Paraná, Mutum Paraná, Vila Abunã, Vista Alegre do Abunã e Extrema. As capturas ocorreram em três diferentes pontos de cada uma das localidades nos meses de fevereiro, julho e outubro de 2011, seguindo a metodologia de coleta por atração humana protegida em dois ambientes, sendo no intradomicílio e no peridomicílio simultaneamente com duração de seis horas. Nas áreas amostradas foram capturados 2.185 anofelinos pertencentes a sete espécies de Anopheles sp. dos quais 95,1% foram identificados como Anophels darlingi, 1,8% An. triannulatus l.s., 1,7% An. deaneorum, 0,8% An. konderi l.s., 0,4 An. braziliensis, 0,1% An. albitarsis l.s., e 0,1% An. benarrochi. Anopheles darlingi foi a única espécie amostrada em todas as localidades enquanto as demais espécies, ocorreram em locais com características singulares.
