Abstract

Arboviruses can be difficult to detect in the field due to relatively low prevalence in mosquito populations. The discovery that infected mosquitoes can release viruses in both their saliva and excreta gave rise to low-cost methods for the detection of arboviruses during entomological surveillance. We implemented both saliva and excreta-based entomological surveillance during the emergence of Zika virus (ZIKV) in French Guiana in 2016 by trapping mosquitoes around households of symptomatic cases with confirmed ZIKV infection. ZIKV was detected in mosquito excreta and not in mosquito saliva in 1 trap collection out of 85 (1.2%). One female Ae. aegyptiL. (Diptera: Culicidae) was found with a ZIKV systemic infection in the corresponding trap. The lag time between symptom onset in a ZIKV-infected individual living near the trap site and ZIKV detection in this mosquito was 1 wk. These results highlight the potential of detection in excreta from trapped mosquitoes as a sensitive and cost-effective method to non invasively detect arbovirus circulation.Graphical Abstract

Abstract

(1) Background: During the COVID-19 outbreak, several studies showed an increased prevalence of extended-spectrum β-lactamase producing Enterobacterales (ESBL-PE) carriage in intensive care units (ICUs). Our objective was to assess the impact of antibiotic prescriptions on the acquisition of ESBL-PE in ICUs during the COVID-19 crisis. (2) Methods: We conducted an observational study between 1 April 2020, and 31 December 2021, in the medical-surgical ICU of the Cayenne General Hospital. We defined two periods: Period 1 with routine, empirical antibiotic use, and Period 2 with no systematic empiric antibiotic prescription. (3) Results: ICU-acquired ESBL-PE carriage was 22.8% during Period 1 and 9.4% during Period 2 (p = 0.005). The main isolated ESBL-PE was Klebsiella pneumoniae (84.6% in Period 1 and 58.3% in Period 2). When using a generalized linear model with a Poisson family, exposure to cefotaxime was the only factor independently associated with ESBL-PE acquisition in ICU (p = 0.002, IRR 2.59 (95% IC 1.42–4.75)). The propensity scores matching estimated the increased risk for cefotaxime use to acquire ESBL-PE carriage at 0.096 (95% CI = 0.02–0.17), p = 0.01. (4) Conclusions: Exposure to cefotaxime in patients with severe COVID-19 is strongly associated with the emergence of ESBL-PE in the context of maximal infection control measures.

Abstract

During the Chikungunya epidemic in the Caribbean and Latin America, pregnant women were affected by the virus in French Guiana. The question of the impact of the virus on pregnancy was raised because of the lack of scientific consensus and published data in the region. Thus, during the Chikungunya outbreak in French Guiana, a comparative study was set up using a cohort of pregnant women. The objective was to compare pregnancy and neonatal outcomes between pregnant women with Chikungunya virus (CHIKV) infection and pregnant women without CHIKV. Of 653 mothers included in the cohort, 246 mothers were included in the case-control study: 73 had CHIKV fever during pregnancy and 173 had neither fever nor CHIKV during pregnancy. The study did not observe any severe clinical presentation of CHIKV in the participating women. There were no intensive care unit admissions. In addition, the study showed no significant difference between the two groups with regard to pregnancy complications. However, the results showed a potential excess risk of neonatal ICU admission of the newborn when the maternal infection occurred within 7 days before delivery. These results suggest that special attention should be paid to neonates whose mothers were infected with CHIKV shortly before delivery. [ABSTRACT FROM AUTHOR]

Abstract

International audience; Among mammals, rodents play a key role in the emergence of viral diseases. In French Guiana, with 36 rodent species recorded in various ecosystems (pristine forests, savannas, anthropized environments), some natural habitats today encounter anthropogenic perturbations that induce changes in community structure and population dynamics. These modifications are sometimes associated with the circulation and emergence of viral pathogens. For 10 years, investigations on the circulation of two rodent-borne viruses, Hantavirus and Mammarenavirus, are underway in rodent populations as well as in humans for hantavirus. These investigations identified viruses from both genera in their potential reservoirs and allow describing the most favourable habitats for the reservoirs of hantavirus where the risk of viral emergence may be higher. We suggest to investigate how anthropic perturbations in rodent communities can drive the emergence of viruses that are currently confined to a small scale and search for evidence of infection in the human population.; Les rongeurs sont décrits comme des réservoirs privilégiés de nom-breuses zoonoses. Du fait de leur forte abondance, de leur dynamique et, pour plusieurs espèces, de leur capacité à coexister avec les populations humaines, les rongeurs jouent un rôle clé dans le maintien et la transmission de pathogènes. En Guyane, 36 espèces de rongeurs ont été recensées et sont présentes aussi bien en forêt primaire et secondaire qu'en savane et en zones urbaines. Certaines populations de rongeurs font face, aujourd'hui, à des perturbations de leurs habitats, du fait des pressions anthropiques. Ces perturbations engendrent des change-ments dans la dynamique des populations et des communautés pouvant avoir un impact sur la circulation et l'émergence des pathogènes. Nous avons récemment identifié des virus appartenant à deux familles virales, Bunyaviridae et Arenavi-dae, dans leurs réservoirs potentiels ainsi que des hantavirus (Bunyaviridae) chez l'homme. De plus, la caractérisation des habitats les plus favorables des espèces réservoirs d'hantavirus a permis de mettre en évidence les zones à plus fort risque d'émergence. Le rôle des communautés de rongeurs doit maintenant être étudié afin de mieux appréhender les mécanismes d'émergence en milieu amazonien.

Abstract

Emerging infectious diseases pose an increasing threat to all nations around the world, including to developed countries. By definition, because they are rare or unknown, public health systems are not well prepared against these emerging diseases. To be fully prepared, countries must have implemented surveillance systems to monitor rare or unusual sanitary events. The capacity of diagnostic laboratories is a key component of surveillance systems since they are in charge of identifying the pathogens responsible for outbreaks in a timely manner. The MediLabSecure project aims at implementing a comprehensive surveillance system for vector-borne diseases around the Mediterranean and Black Sea regions. From 2014 to 2018, the human-virology group of MediLabSecure notably supported the implementation of molecular diagnostic capacities for eight arboviruses and one coronavirus in 19 laboratories of its network through sharing of protocols and reagents, and technical training of the scientific staff of beneficiary laboratories. We report the results of External Quality Assessments for four of these viruses to assess the efficiency of the diagnostic for these threats emerging in the geographic area. The results for these EQA demonstrate the success of the project in the implementation of diagnostic technics for the identification of Dengue, Chikungunya, Zika, and West Niles viruses in laboratories that did not have the capacity before. However, results also show that some work is still to be done to strengthen the newly acquired capacity. The MediLabSecure project deployed an effort to build an efficient capacity in identifying and survey the emergence of arboviruses in the Mediterranean area. Diagnostic technics were successfully implemented in many of the laboratories of the network, but the effort must be maintained over time to strengthen these capacities. [ABSTRACT FROM AUTHOR]

Abstract

Global human health is increasingly challenged by emerging viral threats, especially those observed over the last 20 years with coronavirus-related human diseases, such as the Severe Acute Respiratory Syndrome (SARS) and the Middle East Respiratory Syndrome (MERS). Recently, in late December 2019, a novel Betacoronavirus , SARS-CoV-2, originating from the Chinese city of Wuhan, emerged and was then identified as the causative agent of a new severe form of pneumonia, COVID-19. Real-time genome sequencing in such viral outbreaks is a key issue to confirm identification and characterization of the involved pathogen and to help establish public health measures. Here, we implemented an amplicon-based sequencing approach combined with easily deployable next-generation sequencers, the small and hand-held MinION sequencer and the latest most compact Illumina sequencer, the iSeq100TM system. Our results highlighted the great potential of the amplicon-based approach to obtain consensus genomes of SARS-CoV-2 from clinical samples in just a few hours. Both these mobile next-generation sequencers are proven to be efficient to obtain viral sequences and easy to implement, with a minimal laboratory environment requirement, providing useful opportunities in the field and in remote areas.

Abstract

At the end of 2013, chikungunya virus (CHIKV) emerged in Saint Martin Island, Caribbean. The Asian lineage was identified. Seven months after this introduction, the seroprevalence was 16.9% in the population of Saint Martin and 39.0% of infections remained asymptomatic. This moderate attack rate and the apparent limited size of the outbreak in Saint Martin could be explained by control measures involved to lower the exposure of the inhabitants. Other drivers such as climatic factors and population genetic factors should be explored. The substantial rate of asymptomatic infections recorded points to a potential source of infection that can both spread in new geographic areas and maintain an inconspicuous endemic circulation in the Americas.

Abstract

International audience; A molecular screening of wild-caught rodents was conducted in French Guiana, South America to identify hosts of the hantavirus Maripa described in 2008 in a hantavirus pulmonary syndrome (HPS) case. Over a 9-year period, 418 echimyids and murids were captured. Viral RNA was detected in two sigmodontine rodents, Oligoryzomys fulvescens and Zygodontomys brevicauda, trapped close to the house of a second HPS case that occurred in 2009 and an O. fulvescens close to the fourth HPS case identified in 2013. Sequences from the rodents had 96% and 97% nucleotide identity (fragment of S and M segments, respectively) with the sequence of the first human HPS case. Phylogenetic reconstruc-tions based on the complete sequence of the S segment show that Maripa virus is closely related to Rio Mamore hantavirus. Using environmental descriptors of trapping sites, including vegetation, landscape units, rain, and human disturbance, a maximal entropy-based species distribution model allowed for identification of areas of higher predicted occurrence of the two rodents, where emergence risks of Maripa virus are expected to be higher. Hantaviruses (Bunyaviridae) are distributed worldwide.
