“…In Brazil, when analyzing the correlation between the total number of insects collected and Ae . aegypti house indices (HI) in relation to climatic variables of temperature, humidity, rainfall, among others, regardless of locality, these variables had a direct influence on the distribution and presence of mosquitoes [ 44 , 45 ]. Therefore, it is important to highligth that mosquito populations can change, to better adapt to local environmental conditions [ 46 , 47 ].…”

The high infestation of Aedes aegypti populations in Urabá, Antioquia, Colombia represents a risk factor for increased dengue morbidity and mortality. This study aimed to determine the risk of dengue transmission by estimating the population of Ae. aegypti using entomological indices, density of females per dwelling and inhabitant, and virological surveillance in two municipalities in Colombia. A cross-sectional study was conducted with quarterly entomological surveys in three neighborhoods of Apartadó and Turbo between 2021 and 2022. Aedes indices and vector density per dwelling and per inhabitant were calculated. The Kernel method was used for spatial analysis, and correlations between climatic variables and mosquito density were examined. Virus detection and serotyping in mosquitoes was performed using single-step reverse transcription polymerase chain reaction. The housing, reservoir, and Breteau indices were 48.9%, 29.5%, and 70.2%, respectively. The mean density of Ae. aegypti was 1.47 females / dwelling and 0.51 females / inhabitant. The overall visual analysis showed several critical points in the neighborhoods studied. There was significant correlation of vector density and relative humidity and precipitation in the neighborhoods 29 de noviembre and 24 de diciembre. Additionally, serotypes DENV-1 and DENV-2 were found. The overall indices for dwellings, reservoirs, and Breteau were lower than those recorded in 2014 in Urabá. The vector density results in this study were similar to those reported in other studies conducted in Latin America, and vector infection was detected. The Aedes and density indices are complementary, emphasizing the importance of continuous surveillance of Ae. aegypti to inform appropriate control strategies and prevent future dengue outbreaks in these municipalities.

“…[3,5,6] Its transmission is made by the mosquito Aedes aegypti, the principal vector, which generally uses artificial containers for vector proliferation, making this species predominantly urban. [5][6][7] According to estimations by the World Health Organization (WHO), 80 million people are infected annually, with approximately 550,000 hospitalizations and 20,000 deceases. [8,9] Of these, approximately 50 million are found in tropical and subtropical regions, taking into consideration that currently, 2.5 to 3 billion people live at risk of being infected by this arbovirus.…”

The objective of this paper is to report a clinical case of a patient who after installing an orthodontic mini-implant returned to the dental office seven days later with a severe hemorrhage where it was inserted. Because of the severe character of the hemorrhage, the mini-implant was removed, local compression was performed, medication to control bleeding was given and some lab tests were requested. The patient returned in 24 hours with diagnosis of dengue hemorrhagic fever (DHF). The patient was referred to the specialized hematology service where the diagnosis was confirmed. Past the critical period, a new mini-implant was inserted to continue the orthodontic treatment. It can be concluded from this account that despite the mini-implants being devices of simple installation and easy removal, it is important that the patient's systemic conditions are optimal for their overall effectiveness. Keywords Dengue; Hemorrhage; Orthodontic Anchorage Procedures.

“…Disorderly growth of cities, absence of adequate basic sanitation conditions, and large variations in weather patterns are factors that favor the proliferation of Aedes aegypti in all regions of Brazil 6 . In Mato Grosso State, distribution and abundance of vector populations are influenced by the environmental complexity and the geographic confluence of Pantanal, Cerrado and Amazon biomes 7 .…”

Infections caused by arboviruses that have mostly impacted the Brazilian morbidity and mortality are caused by the same vector, Aedes aegypti. Preventive actions related to the vector are the most effective strategies in the prevention and control of these diseases. This study aimed to associate the knowledge on the vector that transmits dengue, Zika and chikungunya with the sociodemographic and behavioral preventive practices towards Aedes aegypti in the municipality of Tangara da Serra, Mato Grosso State, in the Brazilian Legal Amazon. A probabilistic urban population sampling was obtained by clusters: census sectors and households. The sample size calculation considered 10% of loss and a 1.5 design effect. This is a cross-sectional research carried out through a household survey in February and March 2018. There were 583 participants. The study variables were knowledge on the vector, sociodemographic characteristics and preventive practices related to the vector. The statistical analysis was based on a bivariate analysis and Poisson multiple regressions. Inadequate or insufficient knowledge on the vector Aedes aegypti remained associated with education in the categories illiterate (p<0.001) and 8 years of study or less (p<0.001), in addition to not adopting practices of capping and cleaning the water tank (p=0.002) and not using insecticides at home (p=0.007). It is concluded that there is a need for health communication actions that consider characteristics the population, especially the level of education and previous knowledge on the vector, allowing a dialogical approach and enabling the community participation in preventive practices and control of the vector Aedes aegypti.
