    Transmitted through the infectious bite of mosquitoes of the Aedes genus, dengue virus infects 390 million people worldwide each year. However, 75% of infected persons show no or mild clinical symptoms.

    Scientists at the Institut Pasteur du Cambodge, the Institut Pasteur in Paris and the CNRS provided proof that people infected by dengue virus without clinical symptoms can actually infect mosquitoes that bite them.

    These findings, published in the journal PNAS, on the 9 of November, question established theories that these asymptomatic or mildly symptomatic infections are not involved in the transmission of dengue virus.
