Contribution of Research in the West Indies and Northeast Amazonia to Knowledge of the 2014 –2015 Chikungunya Epidemic in the Americas

The objective of this review is to describe the contributions of research on chikungunya virus infection gained from epidemic in the West Indies and the Guiana Shield.Recent FindingsPrevalence data were similar to those found in the Indian Ocean or Asia during epidemics. Clinically, there is now a better understanding of the typical, atypical, and severe forms. Several studies have insisted on the presence of neurological forms of chikungunya infection, such as encephalitis or Guillain –Barré syndrome. Cases of septic shock due to chikungunya virus as well as thrombotic thrombocytopenic purpura were described for the first time. Given the magnitude of the epidemic and the large number of people affected, this has led to a better description and new classifications of chikunguny a virus infections in specific populations such as pregnant women, the elderly, and children. Several studies also described the behavior of populations faced with an emerging disease.SummaryCurrent epidemiological data from tropical regions highlights the risk of spreading emerging diseases at higher latitudes, especially concerning arboviruses, since the vectorAedes albopictus is already established in many parts of northern countries. A better understanding of the disease and its epidemic dynamics will foster better management, the crucial importance of which was demonstrated during the COVID-19 epidemic.

Health care systems have encountered unprecedented challenges during the coronavirus disease-2019 (COVID-19) pandemic, such as standardizing care in the absence of high-quality data. As an emblematic example, preliminary data and early anecdotal experience suggested that a major driver of COVID-19 pathophysiology was hypercoagulability, suggesting the need for aggressive anticoagulation. In this article, we describe the rapid guidance process for the development of an anticoagulation protocol for COVID-19. Preliminary evidence was collected from multidisciplinary experts within our institution to inform the first protocol ...

AbstractThe COVID-19 pandemic has called for and generated massive novel government regulations to increase social distancing for the purpose of reducing disease transmission. A number of studies have attempted to guide and measure the effectiveness of these policies, but there has been less focus on the overall efficiency of these policies. Efficient social distancing requires implementing stricter restrictions during periods of high viral prevalence and rationing social contact to disproportionately preserve gatherings that produce a good ratio of benefits to transmission risk. To evaluate whether U.S. social distancing ...
