As the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) pandemic continues to expand, healthcare resources globally have been spread thin. Now, disease is rapidly spreading across South America, with deadly consequences in areas already weakened public health systems. The Amazon region particularly susceptible widespread devastation from 2019 (COVID-19) because of its immunologically fragile native Amerindian inhabitants and epidemiologic vulnerabilities. Herein, we discuss...
Traditionally, there has been a frequent, yet incorrect assumption that phlebotomine vectors, animal reservoirs, and human hosts are susceptible to Leishmania infection by single parasite species. However, current evidence supports these new vector-parasite-reservoir associations lend vectors reservoirs greater permissiveness certain species, thus promoting the appearance of coinfection events, particularly in disease-endemic regions.
Chagas Disease (CD), a chronic infection caused by the Trypanosoma cruzi parasite, is Neglected Tropical endemic to Latin America. With re-emergence in Venezuela during past two decades, spread of CD has proved susceptible to, and inhibitable digital, real-time surveillance system effectuated Citizen Scientists communities throughout country. The #TraeTuChipo (#BringYourKissingBug) campaign implemented January 2020, served as such strategy counting on community engagement define current...
Keratomycosis or mycotic keratitis is recognized as one of the major causes ophthalmic morbidity worldwide. The most common organisms linked to keratomycosis include Candida spp., Fusarium and Aspergillus spp. However, varieties saprobic fungi have been reported causative agents keratomycosis. Amongst these are members genus Colletotrichum. Herein we present first case C. chlorophyti infection in a post-corneal transplant patient, suggesting an increasing role for Colletotrichum species...
Persistent headache is a frequent symptom after coronavirus disease 2019 (COVID-19) and there currently limited knowledge about its clinical spectrum predisposing factors. A subset of patients may be experiencing new daily persistent (NDPH) COVID-19, which among the most treatment-refractory primary syndromes.We conducted cross-sectional study in Latin America to characterize individuals with severe acute respiratory syndrome 2 (SARS-CoV-2) infection identify factors associated NDPH....
Fifty-two febrile patients living in Barquisimeto, Venezuela, were screened for arbovirus infection by virus culture during an outbreak of what was thought to be Zika infection. We report identification Mayaro (MAYV) on plasma from one patient, 18-year-old woman with acute illness, arthralgias, and psoriasiform rash. The strain sequenced found most closely related a 1999 French Guiana, which, turn, two 2014 strains Haiti. By contrast, previously reported outbreak-related MAYV sylvatic area...
To date, there is no specific literature available on the determinants for therapeutic failure (TF) with meglumine antimoniate (MA) in Northwestern-Argentina. This study aimed to identify epidemiological, clinical, and treatment-related factors that could be involved TF.We performed a case-control study. Cases were represented by patients who showed TF after administration of first course MA treatment, whereas, controls determined as evolved towards healing cycle received. Crude Odds Ratios...
Numerous reports of neuropsychiatric symptoms highlighted the pathologic potential severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and its relationship onset and/or exacerbation mental disease. However, disease 2019 (COVID-19) treatments, themselves, must be considered as catalysts for new-onset in COVID-19 patients. To date, immediate long-term complications following SARS-CoV-2 infection are currently unknown. Here we report on five patients with possible associated...
ObjectivesTo evaluate the genomic epidemiology of SARS-CoV-2 from Venezuelan migrants living in Colombia.MethodsThis study sequenced 30 clinical specimens collected migrants. Genomes were compared with Wuhan reference genome to identify polymorphisms, reconstruct phylogenetic relationships and perform comparative analyses. Geographic, sociodemographic data also studied across genotypes.ResultsThis demonstrated presence six distinct lineages circulating among migrants, as well a close...
ABSTRACT Introduction Venezuela and Colombia both adopted measures of containment early in response to the COVID-19 pandemic. However, Venezuela’s ongoing humanitarian crisis has decimated its health care system, forced millions Venezuelans flee through porous border with Colombia. The extensive shared border, illegal cross-border transit improvised trails between two countries are major challenges for public authorities. We report first SARS-CoV-2 genomes from Venezuela, present a snapshot...
Due to the necessity control human-to-human spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), overwhelming majority generated data on this virus was solely related genomic characteristics strains infecting humans; conversely, work aimed recover and analyze diversity viral genomes from non-human sources. From a set 3595 publicly available SARS-CoV-2 genome sequences, 128 lineages were identified in hosts, represented by variants concern Delta (n = 1105, 30.7%) Alpha 466,...
We report a rare presentation of Pott's disease caused by M. bovis, suggesting transmission from infected cattle, and only the second case described so far in scientific reports. Noteworthy this was that strain isolated on Stonebrink medium, sodium pyruvate-containing culture medium for isolation mycobacteria. This is frequently ignored diagnostic laboratories laboratory manuals most international health organizations. In general use contains glycerol, carbon substrate considered inhibitory...
