(2020-04-07)Objective: • To provide recommendations on the management of dead bodies in the context of the novel coronavirus (COVID-19) in healthcare facilities. These recommendations are preliminary and subject to review as new ... -
Decline in global transmission rates of COVID-19 through May 6 2020
(2020-05-22)We analyzed COVID-19 data through May 6th, 2020 using a partially observed Markov process. Our method uses a hybrid deterministic and stochastic formalism that allows for time variable transmission rates and detection ... -
Decontamination and Reuse of Filtering Facepiece Respirators
(2020-04)Disposable filtering facepiece respirators (FFRs) are not approved for routine decontamination and reuse as standard of care. However, FFR decontamination and reuse may need to be considered as a crisis capacity strategy ... -
Decreased mortality associated with respiratory viral infections 3 between December 2019 and March 2020 compared to previous year, Southeast France
(2020-03)We observed 39% less deaths associated with common respiratory viruses during colder months of 2019-2020 compared to 2018-2019. Excess mortality associated with influenza virus infections is estimated to be 5.9 per 100,000 ... -
Decreased mortality in COVID-19 patients treated with Tocilizumab: a rapid systematic review and meta-analysis of observational studies
(2020-09-23)Background: We systematically reviewed the literature to answer the following research questions: 1) does IL-6 (receptor) antagonist therapy reduce mortality in COVID-19 patients compared to patients not treated with IL-6 ... -
Demand Analysis and Management Suggestion: Sharing Epidemiological Data Among Medical Institutions in Megacities for Epidemic Prevention and Control
(2020-04-07)During the prevention of coronavirus disease 2019 (COVID-19), epidemiological data is essential for controlling the source of infection, cutting off the route of transmission, and protecting vulnerable populations. Following ... -
Dengue, chikungunya and Zika co-infection in a patient from Colombia
(2016)In Latin America, until 2014, dengue (DENV) was the only virus transmitted significantly by Aedes spp. [1]. Unfortunately since that year, chikungunya (CHIKV) arrived as a relevant secondary arboviral disease, with the ... -
Depression and loneliness during COVID-19 restrictions in the United States, and their associations with frequency of social and sexual
(2020-05-20)To estimate the prevalence of depression and loneliness during the US COVID-19 response, and examine their associations with frequency of social and sexual connections. Methods: We conducted an online cross-sectional survey ... -
