Summary: This study explored the relationship between seasonal climate variability and dengue fever (DF) in Brazil using temperature-based models. The results showed that areas with higher mosquito survival probabilities and shorter extrinsic incubation periods (EIPs) were more likely to have DF case reports, but with significant intra-annual variability. The study also extrapolated the findings to the Americas, mapping the seasonal change in the range of areas suitable for dengue virus transmission and the population living in those areas using climate data from the past decade (2010-2019).

Summary: This review explores the correlations between temperature and dengue epidemics, including the distribution and development of Aedes mosquitoes, the structure of DENV, and the vector competence of Aedes mosquitoes. Additionally, it discusses the immune and metabolic mechanism through which temperature affects the vector competence of Aedes mosquitoes to transmit DENV.

Summary: Dengue is an acute tropical infectious disease transmitted by mosquitoes, posing a major challenge to global public health. The lack of clinically proven specific drugs for prevention and treatment is mainly due to the incomplete understanding of the pathogenesis of dengue fever.

Summary: Epidemiological models that consider arthropod vectors can help reduce the use of insecticides and social costs, and studying dengue is important in this context.

Summary: This study analyzed the relationship between climate change and dengue fever, and found that there is a correlation between increasing temperatures and the rise in dengue cases as well as its geographical expansion. This suggests that climate change is an important driver of the continuous spread of dengue fever in Argentina.

Summary: Aedes aegypti, the main mosquito vector for dengue and other arboviral infectious diseases, has developed high levels of pyrethroid resistance in populations collected from Vietnam and Cambodia. This resistance could pose a serious threat to the control of dengue fever and other Aedes-borne infectious diseases.

Summary: The management of mosquito-borne diseases, particularly dengue fever, is a major challenge in southern coastal Ecuador, especially in Machala where dengue cases are historically high. This study combined mosquito survey data with human dengue infection data to identify household risk factors for dengue in Machala. Certain household characteristics were linked to increased mosquito presence or dengue infections, while the presence of female Aedes aegypti did not predict dengue infections. These findings contribute to improving mosquito control and surveillance efforts in southern Ecuador.

Summary: Dengue fever is not only a major health issue in large urban tropical areas, but is also observed in rural regions. Studies have shown that the physical landscape and sociodemographic factors can influence vector populations and dengue virus incidence rates. Research findings indicate that rural spatial organization can help explain disease risk, with Afro-Ecuadorian households being more susceptible to symptomatic dengue fever compared to Indigenous Chachi households, a relationship that can be attributed to vegetation proximity and distance to public spaces like football fields.

Summary: This article presents a technique using recurrent neural networks to forecast Ae. aegypti mosquito counts, with Earth Observation data inputs as proxies. The method involves a clustering step before model definition, aggregating mosquito count sequences with similar temporal patterns to simplify the task. The model is validated and compared with other state-of-the-art models using in situ data in Brazilian cities.

Summary: Dengue is becoming an increasing global threat in rapidly growing urban areas. This study analyzes nine years of dengue case data in Medellin, Colombia and finds that changes in accessibility and usage of public transit are correlated with changes in the spread and magnitude of localized outbreaks. Locations closer to and with greater utilization of public transit have higher dengue incidence, with a stronger effect observed in lower socioeconomic status areas. These results emphasize the importance of public health services in conjunction with urban growth.

Summary: Various control interventions have shown effectiveness to some extent against arthropod vectors, but sustained control remains a global challenge. Insecticide-based formulations, particularly synthetic pyrethroid deltamethrin, have been found useful, emphasizing the importance of proper delivery of active molecules to target vectors. The microencapsulation of deltamethrin in emulsion binder has shown promising long-term effectiveness against dengue vectors, providing up to 18 months of efficacy.

Summary: This study used data from reported dengue cases and entomological indicators to evaluate the spatial and temporal association between vector infestation and the occurrence of dengue cases. The findings showed low correlation between Ae. aegypti and dengue incidence, and the entomological indexes were not effective in providing dengue risk alerts. Further investigation is needed to understand the variation of factors in areas with and without correlation.

Summary: Dengue Fever (DF) is a viral disease transmitted by mosquitoes, and an outbreak occurred in the Afar Region, Ethiopia in 2019. The study found that Aedes aegypti mosquitoes were responsible for transmitting DF, and most cases occurred in individuals aged 15-49. The results emphasize the need for control measures targeting Aedes mosquitoes and improved entomological surveillance to prevent future outbreaks.

Summary: This study aimed to identify sociodemographic and environmental risk factors for the occurrence of Zika, dengue, and chikungunya in adolescents. The study found that adolescents with better socioeconomic conditions had a lower risk of infection. Additionally, a higher risk of arboviral diseases was associated with a high mosquito infestation index in the school's region. These findings can contribute to the implementation of control measures in population groups and priority locations.
