Abstract: French Guiana (FG), a French overseas territory in South America, is susceptible to tropical diseases, including arboviruses. The tropical climate supports the proliferation and establishment of vectors, making it difficult to control transmission. In the last ten years, FG has experienced large outbreaks of imported arboviruses such as Chikungunya and Zika, as well as endemic arboviruses such as dengue, Yellow fever, and Oropouche virus. Epidemiological surveillance is challenging due to the differing distributions and behaviors of vectors. This article aims to summarize the current knowledge of these arboviruses in FG and discuss the challenges of arbovirus emergence and reemergence. Effective control measures are h ered by the nonspecific clinical presentation of these diseases, as well as the Aedes aegypti mosquito’s resistance to insecticides. Despite the high seroprevalence of certain viruses, the possibility of new epidemics cannot be ruled out. Therefore, active epidemiological surveillance is needed to identify potential outbreaks, and an adequate sentinel surveillance system and broad virological diagnostic panel are being developed in FG to improve disease management.

Abstract: We investigated two mitochondrial genes ( cytb and cox1 ), one plastid gene ( tufA ), and one nuclear gene ( ldh ) in blood s les from 12 chimpanzees and two gorillas from Cameroon and one lemur from Madagascar. One gorilla s le is related to Plasmodium falciparum , thus confirming the recently reported presence in gorillas of this parasite. The second gorilla s le is more similar to the recently defined Plasmodium gaboni than to the P. falciparum–Plasmodium reichenowi clade, but distinct from both. Two chimpanzee s les are P. falciparum . A third s le is P. reichenowi and two others are P. gaboni . The other chimpanzee s les are different from those in the ape clade: two are Plasmodium ovale , and one is Plasmodium malariae . That is, we have found three human Plasmodium parasites in chimpanzees. Four chimpanzee s les were mixed: one species was P. reichenowi the other species was P. gaboni in three s les and P. ovale in the fourth s le. The lemur s le, provisionally named Plasmodium malagasi , is a sister lineage to the large cluster of primate parasites that does not include P. falciparum or ape parasites, suggesting that the falciparum + ape parasite cluster ( Laverania clade) may have evolved from a parasite present in hosts not ancestral to the primates. If malignant malaria were eradicated from human populations, chimpanzees, in addition to gorillas, might serve as a reservoir for P. falciparum .
