RESUMO
RESUMEN El mosquito Aedes aegypti es una especie antropoflica que se ha adaptado a entornos urbanos y es el principal vector de enfermedades como el dengue, la fiebre de Zika, la enfermedad del Chikungunya y la fiebre amarilla, lo que representa una importante carga al sistema de salud, en especial en países tropicales donde es endèmico. Ejercer apropiadamente la vigilancia en salud pública es fundamental para la prevención de estas enfermedades mediante sistemas de información. El propósito de este trabajo es proporcionar una plataforma de tecnologias de la información (TI), integrando tecnologias abiertas Web GIS y mHealth para la vigilancia entomológica del vector a partir de colaboración abierta distribuida para la generación de mapas de infestación. Se realizó un piloto con un grupo focal de 23 estudiantes del curso de epidemiologia, que permitió registrar l20 elementos en 55 reportes en la Universidad de los Llanos para la generación automática de 21 mapas de calor de sintomas, zancudos y criaderos, y un mapa global de infestación. Este trabajo sugiere una perspectiva novedosa de interacción y participación colaborativa de la comunidad con las autoridades de salud soportado por las TI.
ABSTRACT The Aedes aegypti mosquito is an anthropophilic species that has adapted to urban environments and it is the main vector of diseases such as dengue, Zika fever; Chikungunya disease and yellow fever; which represents a significant burden on the health system, especially in tropical countries where it is endemic. Properly exercising public health surveillance is essential for the prevention of these diseases through information systems. The purpose of this work is to provide an information technology (IT) platform, integrating open technologies Web GIS and mHealth for the entomological surveillance ofthe vector; based on crowdsourcing for the generation of infestation maps. A pilot was carried out with a focus group of 23 students from the epidemiology course, which allowed the registration of l20 elements in 55 reports at the Universidad de los Llanos for the automatic generation of 2l heatmaps of symptoms, mosquitoes and breeding sites, and a global infestation map. This work suggests a novel perspective of interaction and collaborative participation of the community with health authorities supported by IT

O exercício adequado da vigilância em saúde pública è essencial para a prevenção dessas doenças por meio de sistemas de informação. O objetivo deste trabalho è fornecer uma plataforma de tecnologia da informação (TI), integrando tecnologias abertas Web GIS e mHealth para a vigilância entomológica do vetor com base em uma colaboração aberta distribuída para a geração de mapas de infestação. Um piloto foi realizado com um grupo focal de 23 estudantes do curso de epidemiologia, que permitiu o registro de l20 elementos em 55 relatórios na Universidad de los Llanos para a geração automática de 2l mapas de calor de sintomas, mosquitos e criadouros, e um mapa de infestação global. Este trabalho sugere uma nova perspectiva de interação e participação colaborativa da comunidade com autoridades de saúde apoiadas por TI.
RESUMO
The present research evaluated the seroprevalence of anti-zika virus (anti-ZIKV) antibodies by virus neutralization test (VNT) in 529 bovines from Andradina city, São Paulo state, Brazil. The reading was performed in an inverted optical microscope, considering reagents when the antibodies were capable to neutralize the ZIKV. Of the 529 samples, 53 (10.01%) were reagents. The animals were healthy at the time of collection. The samples were collected in February 2018, a favorable period for the multiplication of the vector and the highest risk of disease transmission. None of the animals showed anti-bovine viral diarrhea virus (anti-BVDV) antibodies, ruling out a possible cross-reaction, reinforcing the possible contact of the bovine with the ZIKV. In the herd, 88 pregnant females were evaluated; of these, 12 cows were reactive, with no history of reproductive problems or fetal malformations. This is the first research on the seroprevalence of ZIKV in cattle in Brazil, and studies should continue to evaluate cattle as a possible host of this arbovirus and its possible consequences for unique health and agribusiness.

OBJECTIVE@#To assess the knowledge on Zika virus infection among healthcare providers (doctors) in Aceh province, Indonesia.@*METHODS@#A self-administered internet based survey was conducted from 3 May to 3 June 2016 among the members of doctor organizations in Aceh province. A set of validated, pre-tested questionnaire was used to measure knowledge regarding Zika infection and to collect a range of explanatory variables. A two-steps logistic regression analysis was employed to assess the association of participants' demographic, workplace characteristics and other explanatory variables with the knowledge.@*RESULTS@#A total of 442 participants included in the final analysis and 35.9% of them (159) had a good knowledge on Zika infection. Multivariate model revealed that type of occupation, type of workplace, availability of access to medical journals and experience made Zika disease as differential diagnose were associated with knowledge on Zika infection. In addition, three significant source of information regarding Zika were online media (60%), medical article or medical news (16.2%) and television (13.2%).@*CONCLUSION@#The knowledge of the doctors in Aceh regarding Zika infection is relatively low. Doctors who have a good knowledge on Zika infection are more confident to established Zika disease as differential diagnosis in their clinical setting. Therefore, such program to increase healthcare providers' knowledge regarding Zika infection is needed to screen potential carriers of Zika infection.

RESUMO
Los virus causan importante morbilidad y mortalidad, experiencia que se ha manifestado a través de la historia. Un caso específico es el SIDA (Síndrome de Inmunodeficiencia Adquirida), causado por el VIH, que llega a ser mortal sin tratamiento adecuado. Otras enfermedades graves como hepatitis o encefalitis son también causadas por virus. En este contexto llama la atención la reaparición de enfermedades virales en países tropicales, amenazando con convertirse en pandemias, específicamente las fiebres del Zika y Chikungunya. Entre los países más afectados de América del Sur destacan Brasil y Colombia; de ahí la necesidad de realizar una revisión para evidenciar el número de afectados, la sintomatología y los tratamientos realizados, resaltando lo que falta por determinar de estas enfermedades. Se analizaron las acciones preventivas propuestas por la Organización Mundial de la Salud y el Instituto Nacional de Salud y se revisaron los avances en el desarrollo de vacunas efectivas.
Viruses cause significant morbidity and mortality, an experience that has manifested itself throughout history. A specific case is AIDS (Acquired Immune Deficiency Syndrome) caused by HIV, which becomes deadly without proper treatment. Other serious diseases such as hepatitis or encephalitis are also caused by viruses. In this context, the recurrence of viral diseases in tropical countries is threatening to become pandemics, specifically the fevers of Zika and Chikungunya. Among the most affected countries in South America are Brazil and Colombia, hence the need to carry out a review to show the number of people affected, the symptoms and the treatments performed, highlighting what remains to be determined of these diseases. We analyzed the preventive actions proposed by the World Health Organization and the National Institute of Health and reviewed the progress in the development of effective vaccines
