SummaryBackgroundDengue is a vector-borne viral disease impacting millions across the globe. Nevertheless, akin to many other diseases, reports indicated a decline in dengue incidence and seroprevalence during the COVID-19 pandemic (2020-22). This presumably could be attributed to reduced treatment-seeking rates, under-reporting, misdiagnosis, disrupted health services and reduced exposure to vectors due to lockdowns. Scientific evidence on dengue virus (DENV) disease during the COVID-19 pandemic is limited globally.MethodsA cross-sectional, randomized cluster sampling community-based survey was carried out to assess anti-dengue IgM and IgG and SARS-CoV-2 IgG seroprevalence across all 38 districts of Tamil Nadu, India. The prevalence of DENV in the Aedes mosquito pools during 2021 was analyzed and compared with previous and following years of vector surveillance for DENV by real-time PCR.FindingsResults implicate that both DENV-IgM and IgG seroprevalence and mosquito viral positivity were reduced across all the districts. A total of 13464 mosquito pools and 5577 human serum samples from 186 clusters were collected. Of these, 3·76% of mosquito pools were positive for DENV. In the human sera, 4·12% were positive for DENV IgM and 6·4% were positive for DENV IgG. The anti-SARS-CoV-2 antibody titres correlated with dengue seropositivity with a significant association whereas vaccination status significantly correlated with dengue IgM levels.InterpretationContinuous monitoring of DENV seroprevalence, especially with the evolving variants of the SARS-CoV-2 virus and surge in COVID-19 cases will shed light on the transmission and therapeutic attributes of dengue infection.

“…Dengue fever can present with increasing severity, requiring hospital admission and the support of vital organs (Paz-Bailey et al, 2024). The main mechanisms involved in dengue severity comprises dehydration and coagulation disorders (Burattini et al, 2016; Paz-Bailey et al, 2024; Werneck et al, 2018), both conditions which can be aggravated by ambient temperature (Kenney et al, 2014; Schneider et al, 2017). Although the literature is clear regarding the association between temperature and dengue transmission, there is a lack of evidence regarding the association between ambient temperature and dengue severity.…”

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.

“…Its causative agent is the Dengue virus (DENV), with four serotypes in humans (DENV 1-4). 1 , 2 , 3 , 4 , 5 , 6 The pathogenesis of Dengue initiates upon viral entry into the bloodstream, targeting and infecting key cells such as endothelial cells, macrophages, and monocytes. This provokes an immune response and release of a variety of inflammatory mediators.…”
