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: 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: Dengue remains a significant public health concern in Latin America and the Caribbean, with both horizontal and vertical transmission contributing to its spread. While there have been reports of vertical transmission of the dengue virus, its epidemiological significance is still debated.

Summary: A study conducted in a high-risk dengue area in Sri Lanka detected comparatively high rates of VT of DENV in Ae. albopictus and Ae. aegypti larvae, with a shift in the predominant DENV serotype observed from December 2015 to March 2017.

Summary: Global urbanization is leading to the spread of major diseases, including dengue, which requires targeted control strategies. Access to tap water is identified as a key risk factor for exposure to dengue virus, with wealthier areas having higher burden of dengue cases. Improving access to tap water and focusing on mosquito control in winter in socially disadvantaged areas could lead to a reduction in dengue transmission.

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: Dengue viruses (DENVs) cause the greatest public health burden globally among arthropod-borne viruses, with transmission risk expanding from tropical to subtropical regions due to the increasing range of its principal mosquito vector, Aedes aegypti. In Florida, focal outbreaks of dengue fever (dengue) have increased since 2009, and the study found that low passage DENVs were more infectious to and had higher transmission potential by Ae. aegypti mosquitoes. Vector competence across all DENV serotypes was greater for mosquitoes from areas with the highest dengue incidence in south FL compared to north FL, indicating a targeted mosquito-plus-pathogen screening approach could help estimate DENV transmission risk more accurately.

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 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 study investigated the transmission of dengue virus from mildly ill individuals to mosquitoes. The researchers found that transmission risk was highest on the second day of illness, rather than on the first day as previously reported. The level of viremia and the duration of the extrinsic incubation period in mosquitoes were identified as important factors influencing transmission probability. Understanding the variation in infectiousness and contributing factors is crucial for disease surveillance and prevention strategies.

Summary: This study investigated the distribution of pyrethroid resistance mutations in Aedes aegypti in four neighborhoods in Posadas, Argentina. The results showed that approximately 70% of adult females had enhanced resistance to pyrethroids. The distribution of resistance mutations varied between neighborhoods, possibly due to different public health interventions, social habits, and insecticide use.

Summary: From 2010 to 2020, approximately 30,000 cases of dengue were reported in the US territories, with the highest incidence during outbreak years. Children and adolescents aged <20 years were disproportionately affected, highlighting the need for interventions tailored for this population. Ongoing education for healthcare providers and dengue case surveillance and serotyping are important for improving patient outcomes and guiding future control measures.

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: In an increasingly interconnected society, preventing epidemics has become a major challenge. Using an agent-based model, the authors investigated the network morphology of a dengue endemic region considering different serotypes and a small population. The simulation results indicate that the spread of dengue is primarily driven by human-to-human and human-to-mosquito interaction, reinforcing the importance of controlling the vector to prevent episodes of epidemic outbreaks.
