Summary: This ecological study in the Brazilian Amazon aimed to explore potential drivers of dengue emergence, with a focus on deforestation. The results showed no significant association between deforestation and dengue incidence, while access to healthcare was found to be the only significant predictor of dengue incidence.

Summary: Diet-induced nutritional stress can impact mosquito traits, infection outcomes, and immune responses, affecting the transmission potential of dengue virus. Inadequate nutrition during both larval and adult stages compromises key life history traits, increases vulnerability to dengue infection, and suppresses the immune response. Understanding the role of nutritional stress is crucial for studying mosquito vector competence for dengue transmission.

Summary: Through studying dengue case data in 13 cities in the Philippines, it was found that indicators such as the mean age of primary infections and the mean age of those reporting with warning signs represent superior indicators of the dengue force of infection compared to crude incidence. This study provides a framework for national dengue surveillance agencies to routinely monitor transmission and target control interventions to the populations most in need.

Summary: The study in Bhutan identified vulnerable areas for dengue and found differences in vulnerability by location and season, with factors such as population density, landscapes, and road connectivity playing a role. The research provides evidence for the National Vector-borne Disease Control programme to optimize resources for surveillance and control strategies.

Summary: In a study on a long-lived bird species, the snow petrel, it was found that maternal age is correlated with reproductive performance and offspring quality. Older females provide better parental care resulting in higher survival rates, larger body size and faster growth of their chicks, but also increased sensitivity to stress.

Summary: Through next-generation sequencing of samples from the 2017 DENV outbreak in Burkina Faso, 29 DENV genomes were isolated, showing the endemic nature of DENV-2 in the region. Discordant diagnostic results were observed, likely due to genetic divergence between these genomes.

Summary: This study aimed to identify factors associated with dengue virus infection among European travelers and assess how surveillance data could support preparedness against outbreaks in Europe. The study found that Asia was the most common region for dengue infection among travelers, with higher infection rates among travelers returning from Asia. There was an association between the incidence rate in the country of infection and the infection rate among travelers, but no association between the number of travel-related cases and occurrence of autochthonous outbreaks in Europe.

Summary: COVID-19-related disruption has significantly reduced the incidence of dengue in southeast Asia and Latin America in 2020. Measures such as school closures and reduced time spent in non-residential areas are strongly associated with reduced dengue risk.

Summary: Within-species variation in animal body size predicts major differences in life history, for example, in reproductive development, fecundity, and longevity. Large size could fuel different life functions, such as reproduction and survival (the energy reserve hypothesis), while demanding more energy for maintenance (the energy demand hypothesis). Disentangling these hypotheses is difficult due to resource availability, but manipulating body size and resource availability in Hydra oligactis, we found evidence supporting the energy reserve hypothesis and observed different responses in males and females.

Summary: Winter is a harsh season for organisms in temperate zones, but the diversity of individuals within social groups can help buffer against starvation and cold temperatures. However, a study manipulating worker size diversity in ant colonies found no significant impact on colony or individual survival during winter, suggesting potential non-adaptive size diversity in social species.

Summary: The study aimed to estimate the impact of future climate change on dengue transmission by developing a Suitable Conditions Index to forecast dengue risk distributions. Results showed that most Southeast Asian countries exhibited either stable or declining suitability for both Aedes aegypti and Ae. albopictus from 2030 to 2070, while temperate areas of China and Australia showed a less stable pattern with both increases and decreases in suitability for each vector.

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: Government-led entomological surveillance in the Guna Yala region of Panama identified gaps in protection, insecticide resistance, and behavioral patterns of Anopheles vectors that contribute to persisting malaria transmission. These findings underscore the importance of continued and targeted entomological surveillance to inform malaria control strategies.

Summary: As gene drive mosquito projects progress to field trials, monitoring requirements must be assessed to ensure effective introduction and detect unintended spread and resistance. Different monitoring needs exist for population replacement and suppression systems, and lessons can be learned from experiences with Wolbachia-infected mosquitoes and genetically sterile male mosquitoes. Optimal traps and sampling frequency are crucial for detecting and managing gene drive alleles, resistance, and non-functional effector genes.

Summary: This study used an Entomological Surveillance Planning Tool (ESPT) to investigate malaria transmission in the Guna Yala region of Panama. The results showed that there are localized foci of transmission and identified gaps in protection. The data from human behavior observations and mosquito sampling were integrated to guide local vector control decision-making.

Summary: Dengue transmission is influenced by various factors such as environment, Aedes aegypti mosquitoes, dengue viruses, and humans. Mosquito sampling was conducted in multiple urban areas in the Arizona-Sonora desert region to study the factors affecting disease transmission. The abundance of potential vectors, mosquito age, and site-specific temperature were analyzed to estimate disease transmission. Results showed differences in vector abundance between endemic and non-endemic regions, with Tucson, Arizona having a higher estimated abundance than dengue endemic regions in Mexico.

Summary: Malaria is a deadly disease that mainly affects Sub-Saharan Africa, causing over half a million deaths annually. Controlling the mosquito vector Anopheles gambiae is an effective method to control disease spread. In this study, a genetic population suppression system called Ifegenia was developed to interrupt the deadly vector's reproduction. The Ifegenia males were shown to be reproductively viable and capable of passing on genetic mutations to suppress the population. Modeling demonstrated that releasing nonbiting Ifegenia males iteratively can be an effective, controllable, and safe method for population suppression and elimination.
