“…The proposed plans should encompass comprehensive protocols for case management, vector control, and communication techniques. Considering the significant impact of climate on the spread of dengue, 21 , 80 it is imperative for nations to include climate change adaptation methods in their endeavors to mitigate dengue. Surveillance of climate patterns, predicting disease outbreaks, and adjusting vector control strategies in response to evolving environmental circumstances.…”

BackgroundDengue, the world's fastest‐growing vector‐borne disease, has skyrocketed in the 21st century. Dengue has harmed human health since its first known cases among Spanish soldiers in the Philippines to its 21st‐century outbreaks in Southeast Asia, the Pacific, and the Americas. In light of the current circumstances, it is imperative to investigate its origin and prevalence, enabling the implementation of effective interventions to curb the upsurge.MethodsOur study examines the history of dengue outbreaks, and evolving impact on public health, aiming to offer valuable insights for a more resilient public health response worldwide. In this comprehensive review, we incorporated data from renowned databases such as PubMed, Google Scholar, and Scopus to provide a thorough analysis of dengue outbreaks.ResultsRecent dengue outbreaks are associated with rapid urbanization, international travel, climatic change, and socioeconomic factors. Rapid urbanization and poor urban design and sanitation have created mosquito breeding places for dengue vectors. Also, international travel and trade have spread the pathogen. Climate change in the past two decades has favored mosquito habitats and outbreaks. Socioeconomic differences have also amplified the impact of dengue outbreaks on vulnerable communities. Dengue mitigation requires vector control, community engagement, healthcare strengthening, and international cooperation.ConclusionClimate change adaptation and urban planning are crucial. Although problems remain, a comprehensive vector control and community involvement plan may reduce dengue epidemics and improve public health in our interconnected world.

“…The rapid spread of Zika in tropical countries between 2013 and 2016 is an unequivocal demonstration of the presence of the Aedes vector in these parts of the world, as well as the ability of the virus to circulate through infected people, facilitated by air and ground transport 5,6 . Several studies have also shown the in uence of increased temperature and precipitation on the occurrence of dengue outbreaks as reviewed by Damtew (2023) 7 , which may be related to global processes such as climate change.…”

Dengue is rapidly expanding its transmission area across Brazil and much of South America. In this study, data-mining techniques were used to identify climatic and sociodemographic indicators that could explain this trend. The previous circulation of the virus, urbanization, and the occurrence of thermal anomalies for a prolonged period were the main factors that led to increased incidence of dengue in the central region of Brazil. Regions with high altitudes, which previously consisted of a barrier for dengue transmission, became areas of high incidence rates. The algorithm that was developed in this study can be utilized to assess future climate scenarios and plan preventive actions.

“…Dengue incidence is influenced by climate variables, particularly with temperature and rainfall, due to mosquito life cycle and human behaviour changes, resulting in increased transmission risk (Bhatt et al, 2013; Campbell et al, 2015; Colón-González et al, 2021; Lee et al, 2021; Lowe et al, 2021; Suaya et al, 2009; Wibawa et al, 2024). A systematic review and meta-analysis published in 2023 pooled 106 studies evaluating the association between high temperature and heatwaves with dengue incidence (Damtew et al, 2023). There was sufficient evidence to show increased relative risk for high temperatures (pooled RR 1.13 (95% CI, 1.11-1.16, for 1°C increase in temperature), however limited evidence for heatwave events (pooled RR 1.08, 95% CI, 0.95-1.23).…”

“…The majority of articles used a monthly time resolution of the exposure, usually exploring lag effects up to one year. The magnitude of the association reported seemed to depend on the climate zone, showing a greater incidence risk in the tropical monsoon and humid subtropical climate zones (Damtew et al, 2023). In this scenario, projections show that dengue incidence, as well as other mosquito-borne diseases such as Zika, can have increased epidemic potential with the global rising temperature due to climate change (Colón-González et al, 2021; Van Wyk et al, 2023).…”

Background: Climate factors are known to influence seasonal patterns of dengue transmission However, little is known about the effect of extreme heat on the severity of dengue infection, such as hospital admission. We aimed to quantify the effect of ambient temperature on dengue hospitalisation risk in Brazil Methods: We retrieved daily dengue hospitalisation counts by each of 5,570 municipalities across the 27 states of Brazil from 1st of January 2010 to 31st of December 2019, from the Brazilian Public Hospital Admission System (SIH). We obtained average daily ambient temperature for each municipality from the ERA5-land product reanalysis. We combined distributed lag non-linear models with time stratified design model framework to pool an estimate for dose-response and lag-response structures for the association of Dengue hospitalisation relative risk (RR) and temperature. We estimated the overall dengue hospitalisation RR for the whole country as well as for each of the five macro-regions by meta- analysing state level estimates. Findings: 579,703 hospital admissions due to dengue occurred over the 10 years period of 2010 to 2019. We observed a positive association between high temperatures and high risk of hospitalisation for Brazil and each of the five macro-regions. The overall RR for dengue hospitalisation was at the 50th percentile of temperature distribution 1.40 (95% IC 1.27-1.54) and at 95th percentile of temperature the RR was 1.50 (1.38-1.66) for Brazil, relative to the minimum temperature, which was the one with the lowest risk. We also found lagged effects of heat on hospitalisation, particularly observed on the same day (lag 0) both at the 50th percentile and 95th. Interpretation: High temperatures are associated with an increase in the risk of hospitalisation by dengue infection. These findings may guide preparedness and mitigation policies during dengue season outbreaks, particularly on the health-care demand.
