A presença de Aedes albopictus (Skuse) em área urbana representa um risco potencial do inter-relacionamento dessa espécie de mosquito com a população. Este estudo teve como objetivo identificar as formas imaturas de Ae. albopictus encontradas nos depósitos e imóveis do município de Miguel Pereira. O estudo foi realizado no período de 12 meses, ano de 2007, em 27 locais do município de Miguel Pereira, Estado do Rio de Janeiro. As larvas encontradas foram identificadas em laboratório e a análise dos dados foi calculada pelos índices de infestação predial e índice de Breteau. Os tipos de imóveis positivos foram residências (79,44% do total); terrenos baldios (2,56%); comércios (2,56%) e outros tipos de imóveis (15,04%) para Ae. albopictus, e residências (72,72% do total); comércios (6,06%); terrenos baldios (3,03%); e outros tipos de imóveis (18,18%) para Aedes aegypti (L.). Das 3731 larvas, 3562 (95,5%) eram de Ae. albopictus e 169 (4,5%) de Ae. aegypti. O mosquito Ae. albopictus mostrou-se mais presente nos criadouros que Ae. aegypti. A média do índice de infestação predial (IFP) e índice de Breteau (IB) para Ae. albopictus foi 1,0 e 1,9 e para Ae. aegypti de 0,1 e 0,1, respectivamente. As formas imaturas mais abundantemente encontradas no Município de Miguel Pereira no ano de 2007 foram de Ae. albopictus podendo futuramente se tornar um problema de saúde pública. Incidence of Aedes albopictus (Skuse) Immature Form in Miguel Pereira, RJ, Brazil. Abstract. The presence of Aedes albopictus (Skuse) in urban areas represents a potential risk of inter-relationship of this species of mosquito with the population. This study aimed to evaluate the presence of the Ae. albopictus immature forms in deposits and building at Miguel Pereira city, Rio de Janeiro State. The study was carried in the last 12 months, 2007, in 27 locations in Miguel Pereira city. The larvae were identified in laboratory and data analysis was calculated by indicators of building infestation index and the Breteau index. The positive buildings were: residential (79.44% of total); waste land (2.56%), shopping (2.56%) and other types of buildings (15.04%) to Ae. albopictus, and homes (72.72% of total), shopping (6.06%); waste land (3.03%) and other types of buildings (18.18%) to Ae. aegypti (L.). The larvae (3731) collected, 3562 (95.5%) were Ae. albopictus and 169 (4.5%) were Ae. aegypti. The Ae. albopictus are more present in breeding that Ae. aegypti. The average rate of building infestation index (IFP) and Breteau index (IB) for Ae. albopictus was 1.0 and 1.9 and for Ae. aegypti was 0.1 and 0.1, respectively. The Ae. albopictus immature larvae forms were more abundantly found in the Miguel Pereira city in 2007; in future it may become a public health problem.

Resumo. A presença de Aedes albopictus e Aedes aegypti em área urbana representa um risco potencial do inter-relacionamento dessa espécie de mosquito com a população. Este estudo teve como objetivo avaliar a presença do Ae. albopictus (S.) e de Ae. aegypti (L.) no município de Paracambi, Estado do Rio de Janeiro, Brasil. As amostras foram obtidas através de coletas das formas imaturas em depósitos e/ou criadouros (caixas d’água, cisternas, tanques, ocos de árvores, lixo, pneus, etc) em três áreas do município (urbana, rural e área de transição) no período de 12 meses. Os resultados mostraram que Ae. albopictus distribuiu-se igualmente nas áreas urbanas e rurais. A área urbana e a área de transição apresentaram uma maior positividade para Ae. aegypti. Os produtos de descartes, caracterizados por depósito de letra I = outros (artificiais especiais), foram os preferenciais para ambas as espécies de mosquito.   Study of the preferred areas and deposits of Aedes albopictus (Skuse, 1894) and Aedes aegypti (Linnaeus, 1762) in the Paracambi city, Rio de Janeiro, Brazil.   Abstract. The presence of Aedes albopictus (S.) and Aedes aegypti (L.) in urban areas represents a potential risk of inter-relationship of this species of mosquito with the population. This study aimed to evaluate the presence of Ae. albopictus and Ae. aegypti in the Paracambi city, Rio de Janeiro State, Brazil. Samples were obtained from collections of immature forms in deposits (water tanks, cisterns, tanks, hollow trees, trash, tires, etc.) in three areas of the city (urban, rural and the transition area) in the last 12 months. The results showed that Ae. albopictus is also distributed in urban and rural areas. The urban area and the area of transition had a higher positive for Ae. aegypti. They refused material that is the distinguished mark of letter I = other (artificial special) deposit has been preferred for both species of mosquito.

Aedes aegypti is almost completely restricted to human-modified environments, especially urban areas, and rarely invades forests. Ovitraps were utilized in a reserve (Bom Retiro) in Rio de Janeiro state. Eggs of A. aegypti, genetically not differentiable from those of urban mosquitoes, were obtained at a location more than 700 m inside the border of the forest and 900 m away from a trail at the entrance to the forest. The presence of A. aegypti in a primary forest indicates its ability to adapt to sylvatic environments in Brazil, suggesting great potential for the transmission of several arboviruses due to the difficulty in controlling these mosquitoes.

Aedes aegypti (Linnaeus) e Aedes albopictus (Skuse) são vetores de diversas arboviroses entre elas a febre amarela urbana e a dengue, sendo a última um dos maiores problemas no mundo em cidades que possuem clima quente e úmido. Diante dos consecutivos casos de dengue em Vassouras-RJ foi importante averiguar a presença e comportamento do vetor nas diversas épocas do ano e sua predominância no município. Neste estudo observou-se a presença de Ae. aegypti em 10,44% e Ae. albopictus em 89,56% dos 364 ovos que se tornaram viáveis, e sendo o bairro Matadouro, ponto 4, local com maior presença destes culicídeos. Estes dados mostraram que Ae. albopictus está cada vez mais presente na área urbana. Ovitraps for evaluating the presence of Aedes aegypti (Linnaeus) and Aedes albopictus (Skuse) in Vassouras City, State of Rio de Janeiro Abstract. Aedes aegypti (Linnaeus) and Aedes albopictus (Skuse) are vectors of many arboviruses including urban yellow fever and dengue, the latter being one of the biggest problems in the world in cities that have hot and humid climate. Having the consecutive cases of dengue in Vassouras, RJ it was important to ascertain the presence and behavior of the vector in different seasons of year and their predominance in the city. In this study we observed the presence of 10.44% Ae. aegypti and 89.56% Ae. albopictus of the 364 viable eggs and being the Matadouro neighborhood (point 4), the local with the largest presence of these culicids. These data showed that Ae. albopictus is ever more present in urban areas.

Mosquitoes of Aedes species are vectors of several arboviral diseases which continue to be a major public health problem in Nigeria. This study among other things, morphologically identified Aedes mosquitoes collected from Nsukka LGA and used an allele specific PCR amplification for discrimination of dengue vectors. Larval sampling, BG-sentinel traps and modified human landing catches were used for mosquito sampling in two selected autonomous communities of Nsukka LGA (Nsukka and Obimo). A total of 124 Aedes mosquitoes consisting of five (5) different species were collected from April to June, 2019 in a cross-sectional study that covered 126 households, under 76 distinct geographical coordinates. Larvae was mainly collected from plastic containers 73% (n=224), metallic containers 14% (n=43), earthen pots 9% (n=29) and used car tyres 3% (n=9), reared to adult stage 69.35% (n=86), and all mosquitoes were identified using standard morphological keys. Five (5) Aedes mosquito species were captured; Aedes aegypti 83(66.94%), Aedes albopictus 33(26.61%), Aedes simpsoni (4.48%), Aedes luteocephalus (≤1%) and Aedes vittatus (≤1%). Nsukka autonomous community had higher species diversity than Obimo. Allele specific amplification confirmed dengue vectors, Aedes aegypti and Aedes albopictus species on a 2% agarose gel. Since the most recent re-emergence of arboviral diseases is closely associated with Aedes species, findings of this study, therefore, give further evidence about the presence of potential arboviral vectors in Nigeria and describe the role of a simple PCR in discriminating some. Further entomological studies should integrate PCR assays in mosquito vector surveillance.

Growth and development in childhood need to be considered to shape future generations are healthy, intelligent and qualified. Maintenance of children's health is carried out since fetus until age of 18 years. Meanwhile, children at the age of first 5 years of life have a low immune system that is susceptible to various diseases including pulmonary TB disease. One effort to maintain maternal and child health is by giving exclusive breastfeeding. The decline in the use of exclusive breastfeeding in developing countries, especially in urban areas, is the result of socio-cultural changes in the community. Pulmonary TB is a public health problem that is one of the global commitments in the MDG’s that must be controlled. Pulmonary TB is an infectious disease caused by an infection of the Mycobacterium tuberculosis and has attacked almost one-third of the world's population. Children's pulmonary TB is a TB disease that usually attacks children aged 0-14 years. Of the 9 million new cases of TB that occur worldwide each year, an estimated 1 million (11%) of them occur in children under 15 years.

Dengue Hemorrhagic Fever (DHF) is transmitted by Aedes aegypti and Ae. albopictus. Aedes aegypti chooses to live indoors and Ae. albopictus in outdoors. Aedes aegypti has been proven to play a role in dengue transmission in urban areas. It is assumed that suburbs dominated by gardens, so it is possible that Ae. albopictus acts as a vector. The study aimed to analyze the relationship between Ae. albopictus and DHF incidence in suburban area. The study was conducted in Godean, Sleman Regency. 280 ovitrap were placed indoors and outdoors at across seven villages. Each village was represented by one hamlet, so there were 40 ovitrap of each hamlet. The proportion of ovitrap containing Ae. aegypti and Ae. albopictus larvae was calculated. The results showed that Ae. aegypti larvae was more indoors (78.50%) than outdoors (21.45%) in all villages and negatively correlates with DHF (p=0.036; r=-0.776). Aedes albopictus larvae is more commonly found in gardens (80.64%) than in homes (19.36%) and does not correlate with DHF (p = 0.702). It was concluded that in suburban endemic area of ​​Sleman Regency, Ae. aegypti larvae was more indoors and negatively correlated with DHF. Aedes albopictus larva was more in the garden and did not correlate with DHF incidence.

Abstract: Dengue Hemorrhagic Fever (DHF) has become a public health problem in Indonesia because of its high prevalence and ability to spread more widely. In North Sulawesi itself Case Fatality Rate of carrying dengue is increasing from year to year. The local village Malalayang has a high potential for spreading this disease. The result of an  entomology survey on adult mosquitos showed that Aedes sp was found in 40 houses of 80 house samples. From these 40 houses we got 71 mosquito samples. From these 71 samples tested and identified, we found three species: Aedes aegypti (30 samples, 42.25%), Aedes albopictus (22 samples, 30.99%), and Culex sp (19 samples, 26.76%). Mosquito density can be seen from the indices of the resting rates, which were 0.375 for Aedes aegypti, 0.275 for Aedes albopictus, and 0.65 for Aedes sp. Key words: density, adult mosquito, Aedes sp., resting rate.   Abstrak: Demam Berdarah Dengue (DBD) merupakan penyakit yang menjadi masalah kesehatan masyarakat di Indonesia karena prevalensinya yang tinggi dan penyebarannya semakin luas.

A disposição inadequada dos resíduos sólidos, atualmente, constitui um problema para a sociedade, tendo em vista os impactos ambientais que provoca, alterando a qualidade do solo, do ar e dos corpos aquáticos, e representando um risco para a saúde pública. Este artigo aborda aspectos do gerenciamento de resíduos sólidos na região Metropolitana II do Estado do Rio de Janeiro, discutindo ações desenvolvidas nesta área, da coleta à destinação final. Mais especificamente, analisa aspectos relacionados às classes de resíduos, resíduos sólidos gerados e triados, à situação atual da destinação final e ao gerenciamento de resíduos hospitalares, traçando-se, ao final, um panorama da situação do gerenciamento dos resíduos sólidos local. Durante os meses de janeiro a junho de 2008, foram realizadas visitas aos locais de destinação final dos resíduos sólidos - os aterros controlados e lixão, bem como entrevistas com técnicos responsáveis pelas ações de gerenciamento dos resíduos sólidos das Secretarias Municipais do Meio Ambiente, de Obras e de vigilância ambiental em saúde das Secretarias de Saúde, dos municípios da Região Metropolitana II, a saber: Niterói, São Gonçalo, Itaboraí, Maricá, Tanguá, Rio Bonito e Silva Jardim. A região Metropolitana II do Estado do Rio de Janeiro, embora composta por municípios com realidades bastante diferenciadas em termos de desenvolvimento social e econômico, possui grande parcela da população vivendo em condições precárias e sem acesso aos serviços públicos de saneamento, saúde e educação, vulnerável aos impactos ambientais. Verifica-se que a disposição final com o tratamento adequado dos resíduos sólidos constitui importante problema, não só para os governos e políticas públicas locais, mas também para as populações que convivem com os lixões. Destaca-se o importante papel dos catadores informais pelas cidades, muitos se organizando em pequenas cooperativas e grande parte operando em áreas urbanas onde o lixo é armazenado, aguardando coleta pública, ou, ainda, em alguns dos aterros controlados e no lixão da região. Há urgência de implantação de aterros sanitários ou aterro consorciado, desativando-se as áreas atuais de lixões e/ou aterros controlados, com ações de remediação de áreas degradadas, e, enfim, que se adotem soluções que dêem conta dessa importante parcela do saneamento básico, minimizando o impacto negativo dos solos e águas subterrâneas contaminados, visando-se a sustentabilidade da saúde e do ambiente, e o bem-estar das pessoas. Palavras-chave: Resíduos sólidos, Gerenciamento de resíduos sólidos Abstract The inadequate disposal of the solid residues, nowadays, is a social problem, concerning to suffered environmental impact, changing the quality of the soil, the air and of the water, being a risk to the public health. This article is about aspects of solid residues management at Metropolitana II region of the Rio de Janeiro state, discussing the development of actions on this area, from the collect to the final destination. More specifically, we analyze aspects related to the classes of residues, solid residues that were generated and discriminated, the actual situation of the final destination and to the management of the hospitals residues, constructing, at the end, a view of the local management of the solid residues. From January to June of 2008, visits were made at the locals of the final destination of the solid residues – the controlled landfills and the disposal waste areas, as well interviews with responsible technicians about actions of solid residues management of the environmental municipal secretaries, of Metropolitana II region: Niterói, São Gonçalo, Itaboraí, Maricá, Tanguá, Rio Bonito e Silva Jardim. The Metropolitana II region of the Rio de Janeiro state, although composed of very different realities between the municipals, concerning to economic and social development, has great portion of the population living in precarious conditions and without access to sanitary public services, health and education, vulnerable to the environmental impacts. We verify that the final disposal with adequate treatment of the solid residues constitute import problem, not only to the government and local public policies, but also to the population that live within waste. We mark the important function of the informal garbage pickers in the cities, many of them organized in small co-operative societies and a great part acting in urban areas where the trash is stored, waiting public collecting, or at some controlled landfill and disposal waste area. It's urgent the implementation of the sanitary landfills or partnership landfills, discarding the actual areas of waste disposal and/or controlled landfill, with remediation actions on the deteriorate areas, and, finally, solutions must be adopted to solve this important portion of the basic sanitation, minimizing the negative impact of the soil and contaminated subterranean water, aiming the health and the environmental support, and the well being of people. Keywords: Solid waste, Solid waste management

Abstract: Dengue hemorrhagic fever (DHF) is a viral disease that can cause death within a very short time (a few days). The main vector of DHF is Aedes aegypti mosquito, whereas the potential vector is Aedes albopictus. In the context of prevention of DHF, environmental data associated with bionomics mosquito vector of DHF, the Maya Index, are needed. DHF is still a public health problem. And for the case that there is in the city of Manado in 2013, in this case in the district of Singkil, acquired as many as 43 cases of dengue hemorrhagic fever. This study aimed to describe the Maya Index at the houses of dengue hemorrhagic fever patients in the village of West Kombos, Singkil districts. Maya Index is based on hygiene risk index (HRI) and breeding risk index (BRI). This was a descriptive study. Samples were houses of patients with DHF in 2015 from January to December. The results showed that there were four patients during the year 2015. Observation of the four houses and calculation of the data indicated that two houses were in low category of Maya Index, one house in medium category of Maya Index, and one house in high category of Maya Index. Keywords: dengue hemorrhagic fever, Maya index Abstrak: Demam berdarah dengue (DBD) adalah penyakit virus yang berbahaya karena dapat menyebabkan kematian dalam waktu yang sangat singkat (beberapa hari).
