Yellow fever is an acute mosquito-borne flavivirus infection characterized in its full-blown form by fever, jaundice, albuminuria, and haemorrhage. Two forms are distinguished: urban yellow fever in which the virus is spread from person to person by peridomestic Aedes aegypti mosquitoes and jungle (sylvan) yellow fever transmitted by tree-hole breeding mosquitoes between non-human primates and sometimes humans. Yellow fever is endemic and epidemic in tropical areas of the Americas and Africa but has never appeared in Asia or the Pacific region. Prevention and control are effected principally through yellow fever vaccination.

RESUMOObjetivo: identificar os desafios enfrentados pelos agentes comunitários de saúde e agentes de combate a endemias na prevenção e controle da disseminação do mosquito Aedes aegypti. Método: estudo qualitativo realizado com 12 agentes comunitários de saúde e sete agentes de combate a endemias. Os dados foram produzidos a partir de entrevista semiestruturada e analisados com a técnica do Discurso do Sujeito Coletivo. Resultados: verificou-se que as maiores dificuldades enfrentadas por estes agentes são o descaso, a falta de compromisso e a conscientização da comunidade, além da gestão, que não se apresenta de modo efetivo no processo. Conclusão: propõe-se, assim, uma maior efetivação das ações de educação em saúde junto à população, investimento em educação permanente e sensibilização da gestão pública. Descritores: Prevenção e controle; Participação da Comunidade; Saúde Pública; Vírus da Dengue; Zika Vírus; Vírus Chikungunya.ABSTRACT Objective: to identify the challenges faced by community health agents and agents to combat endemic diseases in the prevention and control of the spread of the Aedes aegypti mosquito. Method: a qualitative study carried out with 12 community health agents and seven agents to combat endemic diseases. The data were produced from a semi-structured interview and analyzed using the Collective Subject Discourse technique. Results: it was verified that the greatest difficulties faced by these agents are the neglect, lack of commitment and awareness of the community, besides the management, that is not presented in an effective way in the process. Conclusion: it is proposed, therefore, a greater effectiveness of the actions of health education with the population, investment in permanent education and public management awareness.

Dengue is the most important mosquito-borne viral infection to affect humans. It is an RNA virus in the Flavivirus genus, family Flaviviridae. There are four closely related but serologically distinct viral serotypes, all of which may cause disease. Following infection with one serotype there is lifelong immunity to that serotype but the possibility of more severe disease during a subsequent infection with a different serotype. The primary mosquito vector is Aedes aegypti. Recent estimates suggest around 100 million symptomatic, and many more asymptomatic, infections occur annually worldwide. The disease is hyperendemic in many large Asian cities, and is also a significant problem in the Pacific region and in the Americas.

Dengue Haemograffic fever is a vector borne disease which caused outbreaks and death. There is no applied vaccine until now, so the effort of prevention and control is to terminate chain of infection mosquito breeding. Factors which influenced  the female mosquitoe to lay their eggsare type of container, color, water, temperature, water source, humidity and environment condition. This study was conducted to determine the preferences of Ae. aegypti mosquitoes to lay aggs in various colors ovitrap in the laboratory of Balai Litbang P2B2 Donggala, January until March 2015. Three repetitions with plastic cup black, blue, white, yellow and pink have been performed with water and filter pappers. 30 mosquitoes blood saturation included in the containers with various colors. The result showed that most of female mosquito laid their eggs in plastic cup black (53,2%). ANOVA analysis showed that the diversity of colors ovitrap produce different the number of eggs Ae. aegypti in each type of countainer color. It is recommended to use black ovitrap for controling populations of Ae, aegypti in environment with regular monitoring.

Objectives. This scoping review aimed to support a landscape analysis to identify lessons learned about intersectoral collaborations (ISCs) by describing their existing models in the context of dengue, malaria and yellow fever. Methods. A scoping review following the methodology of Joanna Briggs Institute was performed using the following inclusion criteria: studies involving humans; studies discussing intersectoral collaborations, malaria/dengue/yellow fever, and prevention or control at any level; and studies in countries endemic for the aforementioned diseases. Studies were screened using Covidence, while data were extracted using NVivo. Results. Of the 7,535 records retrieved, 69 were included in the qualitative analysis. Most ISCs were initiated by multilateral organizations and ministries of health, and none by communities. Strategies included advocacy, health education, research, public health measures, resource mobilization, service delivery and training; mostly employed on a community level. Monitoring and evaluation were mostly formative, ongoing, and participatory. Gaps included administrative and policy barriers, resource shortages, and inadequate research and training. Conclusions. Multiple models of ISC exist in the literature. There is a need to develop a comprehensive framework for an effective and sustainable multisectoral approach for the prevention and control of VBDs ensuring adequate resources, active stakeholders, and strategies that span the entire socio-ecological spectrum.
