Abstract objective Since the 1980s, dengue incidence has increased 30-fold. However, in 2017, there was a noticeable reduction in reported dengue incidence cases within the Americas, including severe and fatal cases. Understanding the mechanism underlying dengue’s incidence and decline in the Americas is vital for public health planning.

Scientists from the Institut Pasteur in Paris and the Institut Pasteur in Cambodia, in collaboration with teams from the CNRS and Inria, have demonstrated that asymptomatic dengue infection in children is associated with activation of the immune system via control mechanisms, resulting in the elimination of viral infection without excessive immune activation.
Nov 17, 2017 · Dengue fever is caused by a mosquito-transmitted flavivirus resembling Zika virus. Both viruses can cause severe diseases in humans with catastrophic sequelae. It has been suspected in humans, and shown in animal models, that the host's immune responses can make disease worse. Katzelnick et al. examined data from a long-term study of Nicaraguan children exposed to dengue virus (see the ...
engue virus (DENV) infection is the most important arthropod-borne human viral disease worldwide. An estimated 390 million infections occur each year, of which 500,000 cases develop severe dengue and 20,000 die (1). DENV is a single-stranded RNA virus with four serotypes (DENV-1 to -4). Infection by any DENV serotype induces a
