Abstract
Since 2018, a dengue epidemic has been ongoing in the French overseas department of Reunion Island, in the Indian Ocean, with more than 25,000 serologically confirmed cases. Currently, three dengue serotypes have been identified in Réunion Island (DENV-1, DENV-2, and DENV-3) progressing in the form of epidemic outbreaks. This arbovirus is mainly transmitted by mosquitoes of the genus Aedes and may be responsible for serious clinical forms. To date, very few cases of kidney transplant-related dengue virus infection have been described. Here we report the first case of severe dengue virus infection related to kidney transplantation from a patient previously infected with dengue. Testing for dengue fever with PCR search in donor's urine may help complete the pretransplant assessment in areas where this disease occurs.
