1 day ago · Dengue is the most prevalent arthropod-borne viral infection, annually affecting between 100–400 million individuals worldwide, with roughly half of the world’s population at risk of contracting the disease [1,2]. Dengue is caused by dengue virus (DENV), which, like other mosquito-borne viruses of medical relevance including Zika, Japanese ...
May 1, 2024 · The global burden of the mosquito-borne dengue virus continues to increase with an estimated 3.9 billion people at risk of infection [].During the last two decades, the number of reported dengue cases has increased by more than eightfold to over 4 million in 2019, particularly in tropical and sub-tropical regions in the Americas and Asia [].

May 14, 2024 · Key points. Dengue virus RNA can usually be detected by nucleic acid amplification tests (NAAT) for the first 7 days of illness. A positive NAAT (e.g. RT-PCR) result confirms current dengue virus infection. A negative NAAT result does not rule out infection.
Apr 24, 2024 · Our findings suggest that dengue disease risk is determined by a highly nuanced picture, where the specific impact of an infecting virus on patterns of disease will depend on both the characteristics of that virus and the immunity derived from previous circulations of antigenically different viruses, with the effect of a particular virus being ...
Apr 23, 2024 · Most people with dengue have mild or no symptoms and will get better in 1–2 weeks. Rarely, dengue can be severe and lead to death. If symptoms occur, they usually begin 4–10 days after infection and last for 2–7 days. Symptoms may include: high fever (40°C/104°F) severe headache. pain behind the eyes.
Apr 25, 2024 · Dengue is an acute febrile illness viral infection caused by dengue virus (DENV), which is transmitted to humans through the bite of an infected Aedes mosquito 1,2,3.There are four genetically ...
4 days ago · Dengue virus (DENV) is currently causing epidemics of unprecedented scope in endemic settings and expanding to new geographical areas. It is therefore critical to track this virus using genomic surveillance. However, the complex patterns of viral genomic diversity make it challenging to use the existing genotype classification system. Here we propose adding two sub-genotypic levels of virus ...
