“…Arboviruses have posed a major challenge to public health due to weather and environmental changes and deforestation, which favor viral spread and transmission, as well as transposition of the barrier between species [6]. Arbovirus contamination and the growing numbers registered throughout the country bring proof that an epidemic is currently underway, especially dengue, chikungunya, and zika.…”

Objective: Survey the prevalence of arbovirus infections among pregnant women accessing care at a maternity hospital school in Recife, Pernambuco, Brazil.Method: Descriptive, cross-sectional, retrospective, and quantitative study, carried out with data collected from the notification forms filled in during obstetric screening between August 2015 and July 2016. Collected data about age, sex, place of residence, color, education level, if pregnant, municipality of the occurrence, clinical data related to disease or injury and the information on the achievement and results of the laboratory tests that are used as criteria of confirmation.Results: Positive serology was found for arboviruses in 40.2% of the 103 suspected cases. Serology was not performed or it showed inconclusive results in 59.8% of the cases. Dengue fever occurred in 44% of the cases, chikungunya in 34%, and zika fever in 22%. Infections were more frequent among pregnant women over 20 years old (60,2%) and 39,8% was between 15 and 19 years old. They had low income family and low schooling levels, living in Recife (48.5%) and Olinda (24.3%), Pernambuco, Brazil. The most frequently mentioned symptoms were arthralgia (94%), exanthema (82%), and fever (78%). Infections occurred within the first trimester of pregnancy (54.5%), 63.3% of the pregnant had to be hospitalized, and 45.4% of them did not undergo morphological ultrasonography. Most babies were born full-term and they had adequate weight. The prevalence of microcephaly was 9.7% when considering cases of arboviruses and 62.5% when considering specific cases of zika fever.

“…Brazil has a large land area, located in a predominantly tropical zone, providing suitable sites for vector existence, thus it favors the occurrence of arboviruses. Regarding Aedes aegypti, the vector is observed in all Brazilian regions, in more than 4,000 municipalities [2][3][4][5][6].…”

“…However, detailed studies of feeding behavior and biology of the group are still incipient (Forattini 2002). In Brazil, the genus Wyeomyia may be involved in the natural transmission of arbovirus Ilheus, causing fever and encephalitis (Lopes et al 2014). However, the species of this genus are not yet listed as important vectors of viral agents.…”

“…Ecological and epidemiological studies show the increasing number of recipients in urban areas as a result of waste discarded by modern society . Consequently, providing sites for mosquitoes of Aedes (Stegomyia) Theobald, in urban areas (Cunha et al 2002), being responsible for transmitting dengue, Chikungunya, zika virus and yellow fever throughout the Americas, Africa and Asia (Marcondes & Ximenes 2016, Lopes et al 2014.…”

The community of Diptera (Insecta) colonizing axils of Alocasia macrorrhizos (L.) G.Don (Araceae), with records of Aedes aegypti (L.) and Aedes albopictus (Skuse) in urban areas of Manaus, Amazonas

Alocasia macrorrhizos (L.) G.Don grows and proliferates in shaded areas in several forest fragments in urban zones. The adult plant has axils that accumulate rain water (phytotelmata) and serve as breeding sites for several families of aquatic insects. The objective of this study was to determine the composition of the entomofauna associated with water accumulations in axils of A. macrorrhizos in urban areas of Manaus, Brazil. Individuals of A. macrorrhizos were sampled in five forest fragments, between April/2005 and March/2007 in urban areas of Manaus, totaling 184 sampling units. A manual suction hose was used for the removal of entomofauna. A total of 1,941 immatures of Diptera were collected representing the following families: Culicidae (96.5%), Chironomidae (2%), Psychodidae (0.7%), Ephydridae (0.7%) and Corethrellidae (0.1%). Five Culicidae species were identified: Wyeomyia melanocephala Dyar & Knab, 1906 (91.7%), Wy. ypsipola Dyar, 1922 (4.3%), Aedes albopictus (Skuse, 1894) (2.3%), Ae. aegypti (Linnaeus, 1762) (1.5%) and Johnbelkinia longipes (Fabricius, 1805) (0.1%). The members of Culicidae were the most abundant, confirming the importance of this group in communities associated with phytotelmata, with a positive relation to the volume of water (p < 0.05). The occurrence of Ae. aegypti and Ae. albopictus in axils of A. macrorrhizos demonstrates the potential of this Araceae as a breeding site of these medically important species. However, the real contribution of this Araceae in the maintenance and dispersion of populations of these two species of mosquitoes throughout the year should be further studied.

“…This term is used not only because the viruses are carried and spread by arthropods, but mainly for the fact that part of their replication cycle occurs in insects and that it is transmitted to human beings by the bite of hematophagous arthropods [7]. There are at least 135 arboviruses known to cause disease in the human being [8].…”
