In march 2020, a pandemic of respiratory infection due to the SARS-CoV2 is underway, dengue fever epidemics are at the same time present in many regions of the inter-equatorial zone. We report the first cases of covid19-dengue co-infection, which occurred in Mayotte, a French island in the Indian Ocean.

In march 2020, a pandemic of respiratory infection due to the SARS-CoV2 is underway, dengue fever epidemics are at the same time present in many regions of the inter-equatorial zone. We report the first cases of covid19-dengue co-infection, which occurred in Mayotte, a

French island in the Indian Ocean. 

reported, mostly DENV1 serotypes. It is therefore likely that the patient acquired dengue upon returning from France, as the incubation time for COVID-19 is 3 to 5 days in general, but can be up to 14 days, as it is 2 to 7 days for dengue fever, being up to 14 days as well.

To our knowledge, COVID19 and dengue virus co-infection has not been reported yet, In the present case, it was not the biological assessment which challenged the clinicians, but the occurrence of a diffuse exanthema, which prompted the search for dengue fever. In

Thailand, at the beginning of the epidemics, a case was reported describing a COVID-19 patient who initially presented with a skin rash, which was initially considered as a dengue infection, before the diagnosis was corrected. 5 In Lombardy, Italy, erythematous rash was the most common lesion among 88 patients with proved COVID-19 infection. Thus, COVID-19 may present with cutaneous manifestations, which could be confused with dengue fever.

To conclude, COVID1-19 and dengue virus epidemics occur at the same time in tropical areas and lead to 2 major challenges: the misdiagnosis of two infections with similar presentation and the risk of greater severity.
