“…Regarding the urban zoonotic transmission of YF and this case of a YFV-infected marmoset, several factors must be taken into account: the presence of favorable conditions for the exposure of susceptible people; unvaccinated susceptible individuals; most marmosets usually have a low viral load, and their role in the maintenance and transmission of YF is not fully understood; and others ( 1 , 4 , 25 , 27 ). Therefore, it is crucial to consider the risk of infected vector mosquitoes in the YFV transmission and maintenance in urbanized marmoset populations and also in the zoonotic viral spread for unvaccinated humans in natural parks and forested areas in the cities.…”

“…Coinfections can significantly impact the transmission, clinical progression, and control of human infectious diseases, such as in the case of immunocompromised patients (such as those with AIDS) experiencing acute toxoplasmosis or being exposed to multiple other opportunistic infections. To date, coinfection of the YFV with other pathogens has not been reported in humans worldwide, but it is important to include it in the differential diagnosis of other icterohemorrhagic diseases such as acute leptospirosis ( 27 ).…”

Free-ranging non-human primates (NHP) can live in anthropized areas or urban environments in close contact with human populations. This condition can enable the emergence and transmission of high-impact zoonotic pathogens. For the first time, we detected a coinfection of the yellow fever (YF) virus with Toxoplasma gondii in a free-ranging NHP in a highly urbanized area of a metropolis in Brazil. Specifically, we observed this coinfection in a black-tufted marmoset found dead and taken for a necropsy by the local health surveillance service. After conducting an epidemiological investigation, characterizing the pathological features, and performing molecular assays, we confirmed that the marmoset developed an acute fatal infection caused by T. gondii in coinfection with a new YF virus South American-1 sub-lineage. As a result, we have raised concerns about the public health implications of these findings and discussed the importance of diagnosis and surveillance of zoonotic agents in urbanized NHPs. As competent hosts of zoonotic diseases such as YF and environmental sentinels for toxoplasmosis, NHPs play a crucial role in the One Health framework to predict and prevent the emergence of dangerous human pathogens.

Purpose of Review The aim of this study was to compile all cases of yellow fever (YF) recorded in the Guiana Shield (GS), a region located on the northeastern shore of South America. Recent Findings Yellow fever causes several deaths in French Guiana during the last years. In this context, we wanted to know if it was due to a lack of vaccination or a reemergence of YF as in Brazil and if it was the same trouble in the neighborhood countries. Summary People living in or returning from the GS with YF-compatible symptoms confirmed by reverse transcriptase polymerase chain reaction between 1990 and 2022 were included. In French Guiana (FG), patients were identified through results from the National Reference Center for Arboviruses at the Pasteur Institute in FG and hospital medical charts. For the other countries, medical literature and the WHO database were reviewed. Public health and infectious diseases specialists were solicited to identify unknown and unpublished cases. Nine patients were identified in the study period: five in FG, two in Venezuela, one in Suriname, one in Brazil, including six autochthonous people, Guiana Shield native, and three tourists. The case fatality rate was 7/9 (78%) within 8 days (range: 7–11 days). The M/F sex ratio was 6/3 (2). They had severe liver involvement progressing to multivisceral failure in 89% of cases. Only the two native Amerindian patients in FG had previously benefited from a YF vaccination in childhood and/or for more than 10 years. In conclusion, the sylvatic cycle of the YF virus is likely to persist in this region. Absence of vaccination or unknown immunization status was documented in most patients (78%). The mortality rate of this case series was high thus highlighting the need to strengthen vaccination coverage for the population and travelers to the GS.
