Dengue is a viral disease transmitted by mosquitoes that are primarily found in tropical and subtropical regions. The disease is caused by four closely related dengue viruses (DEN-1, DEN-2, DEN-3, and DEN-4) and can result in a wide range of symptoms, from mild fever and flu-like symptoms to severe complications such as dengue hemorrhagic fever and dengue shock syndrome. Research in the field of dengue focuses on understanding the epidemiology, transmission dynamics, pathogenesis, diagnosis, and treatment of the disease. This includes studies on mosquito control, vaccine development, and strategies to prevent and manage outbreaks. Additionally, research in this area often explores the impact of climate change, urbanization, and globalization on the spread of dengue. Overall, research on dengue is crucial for developing effective prevention and control measures to reduce the burden of this disease on public health.
