Mayaro virus (MAYV) is an arbovirus that is endemic to tropical forests in Central and South America, particularly within the Amazon basin. In recent years, concern has increased regarding MAYV’s ability to invade urban areas and cause epidemics across the region. We conducted a systematic literature review to characterise the evolutionary history of MAYV, its transmission potential, and exposure patterns to the virus. We analysed data from the literature on MAYV infection to produce estimates of key epidemiological parameters, including the generation time and the basic reproduction number, R 0 . We also estimated the force-of-infection (FOI) in epidemic and endemic settings. Seventy-six publications met our inclusion criteria. Evidence of MAYV infection in humans, animals, or vectors was reported in 14 Latin American countries. Nine countries reported evidence of acute infection in humans confirmed by viral isolation or reverse transcription-PCR (RT-PCR). We identified at least five MAYV outbreaks. Seroprevalence from population based cross-sectional studies ranged from 21% to 72%. The estimated mean generation time of MAYV was 15.2 days (95% CrI: 11.7–19.8) with a standard deviation of 6.3 days (95% CrI: 4.2–9.5). The per-capita risk of MAYV infection (FOI) ranged between 0.01 and 0.05 per year. The mean R 0 estimates ranged between 2.1 and 2.9 in the Amazon basin areas and between 1.1 and 1.3 in the regions outside of the Amazon basin. Although MAYV has been identified in urban vectors, there is not yet evidence of sustained urban transmission. MAYV’s enzootic cycle could become established in forested areas within cities similar to yellow fever virus.

Introduction: Second-line drugs such as linezolid and daptomycin are used for treatment of vancomycin-resistant Enterococcus (VRE) infections. Objective: A systematic review to evaluate treatment of VRE bacteremia with linezolid versus daptomycin. Methods: A search was done in the databases of Pubmed, Embase, Scopus, ScienceDirect, CENTRAL, Lilacs and Google Scholar to identify studies comparing treatment with daptomycin or linezolid of patients infected by VRE up to July 2015. Result: Only 15 studies were included of a total of 1.307 records. There were no differences between daptomycin and linezolid with respect to mortality at 30 days. Microbiological cure was better with daptomycin (OR: 0.64; 95 % CI: 0.45-0.92), whereas there was no difference between the two antibiotics with respect to clinical cure, need to ICU admission, and the occurrence of adverse effects such as thrombocytopenia, neutropenia and renal failure. Conclusions: No significant differences were observed between daptomycin and linezolid in reference to mortality of patients infected with VRE, although daptomycin treatment produced a faster microbiological cure.

RESUMEN Introducción: para el tratamiento de las infecciones por Enterococcus resistente a vancomicina (ERV) se emplean fármacos de segunda línea como daptomicina y linezolid. Objetivo: hacer una revisión sistemática para evaluar el tratamiento de la bacteriemia por ERV, con daptomicina o linezolid. Metodología: búsqueda electrónica en las bases de datos de Pubmed, Embase, Scopus, ScienceDirect, CENTRAL, Lilacs y Google Académico, para identificar estudios anteriores a julio de 2015 que hayan comparado los tratamientos con daptomicina o linezolid de pacientes infectados por ERV. Resultados: se incluyeron 15 estudios de 1307 registros. No hubo diferencias entre daptomicina y linezolid con respecto a la mortalidad a 30 días. Con la daptomicina se logró más tempranamente el control microbiológico (OR: 0,64; IC95 %: 0,45-0,92). No hubo diferencias entre los dos antibióticos en cuanto a la mejoría clínica, la necesidad de admisión a la UCI o la aparición de efectos adversos como trombocitopenia, neutropenia e insuficiencia renal. Conclusiones: no encontramos diferencias entre daptomicina y linezolid en cuanto a la mortalidad de pacientes infectados por ERV, aunque con la daptomicina se logró una cura microbiológica más rápida.
