For the past two decades, Bangladesh has faced recurrent dengue outbreaks, with the most recent occurring in 2023. We investigated the socioeconomic, clinical, and laboratory aspects of patients diagnosed with dengue during this outbreak. This observational study was conducted from July to September 2023 at Dhaka Medical College Hospital and Chittagong Medical College Hospital, and included 450 confirmed cases of dengue. Sociodemographic information was collected via face-to-face interviews, clinical examinations, and laboratory testing, which was done within 24 hours of admission. Dengue severity was classified according to the 2009 WHO dengue guidelines. Notably, 17% of patients experienced severe dengue, and 89% of those with nonsevere cases exhibited at least one warning sign. Most patients were young adults (mean age, 33 years), with a nearly equal male-to-female ratio. Common clinical presentations included fever (95%), myalgia (62%), and headache (58%), whereas warning signs such as vomiting (54%) and abdominal pain (39%) were prevalent. Plasma leakage indicators, including ascites, pleural effusion, and edema, were found predominantly in severe cases. Laboratory findings revealed leukopenia, thrombocytopenia, and elevated hepatic enzymes (alanine aminotransferase and aspartate aminotransferase) in nearly half the patients. An elevated hematocrit level was associated with severe dengue. We report that a substantial number of patients developed severe dengue during the epidemic in 2023, and provide detailed clinical-epidemiological profiles of the patients, offering valuable insight into management of dengue cases.

Dengue is an increasing threat to individuals living in or visiting endemic countries. Effective vaccines have become available, but their use in travelers is typically only recommended to individuals with documented prior infection. We present a fatal case of severe dengue in an unvaccinated traveler without known prior dengue virus infection but longitudinal serologic and molecular evidence for secondary infection.

Background: Previously we identified a complex of non-structural protein (NS) 1 - Thrombin (NST) in dengue infected patients. Here, we investigated how the concentration of NS1 and NST differ in various dengue severity levels as well as their demographic and clinical features. Several comorbid (hypertension, diabetes, and chronic renal failure) often found in dengue patients were also measured and analyzed.

Dengue infection poses a significant public health challenge in tropical countries. In Thailand, children ages 5-14 years are among the groups with the highest incidence of dengue. This study aimed to determine the prevalence of gastrointestinal (GI) manifestations in children with dengue infection and assess prognostic factors for severe dengue.

Dengue fever, caused by the dengue virus and transmitted by mosquitoes, poses a significant global health threat, particularly in tropical and subtropical regions. Severe cases can manifest as dengue hemorrhagic fever (DHF) or dengue shock syndrome, leading to complications such as plasma leakage, fluid accumulation, respiratory distress, severe bleeding, and organ impairment. Among these complications, gastrointestinal (GI) bleeding is particularly concerning due to its potential to rapidly deteriorate the patient's condition.

Dengue, a hyperendemic arbovirus thriving in tropical and sub-tropical climates globally, has seen a significant surge in Brazil over the past 5 years. Presently, the country faces an epidemic, posing a huge challenge to Public Health authorities due to the potentially lethal nature of severe infections. Based on Hahnemannian concepts and on the historically reported efficacy of homeopathy in fighting epidemics, this study aimed to provide supporting evidence for a homeopathic genus epidemicus approach to prevent severe forms of dengue.
