Cochrane has released a new Special Collection: Coronavirus (COVID-19): Infection control and prevention measures. This Cochrane Library Special Collection pulls together the Cochrane Reviews that are identified as most directly relevant to the prevention of infection. The 2019 Coronavirus outbreak (COVID-19) was declared a global Public Health Emergency by the World Health Organization (WHO) on 30th January 2020. In order to ensure immediate access to Cochrane Reviews of potential relevance, this Cochrane Library Special Collection assembles Cochrane Reviews identified as most directly relevant to the prevention of infection. It includes reviews that evaluate the effects of interventions referenced in the WHO interim guidance for the 2019 coronavirus outbreak (28 January 2020), as well as other potentially relevant reviews from three Cochrane Networks: Cochrane Public Health and Health Systems; Cochrane Musculoskeletal, Oral, Skin and Sensory; and Cochrane Acute and Emergency Care. Many reviews in this collection have associated Cochrane Clinical Answers (CCAs), with links provided. This Special Collection will be updated to ensure it remains applicable as the situation changes, and as WHO guidance evolves. It will also draw on the knowledge of Cochrane groups in affected regions. The different natures of pathogens and their modes of transmission compared with what is currently known about COVID-19 may limit the applicability of the evidence summarized in these reviews. Please note that the reviews included in this Special Collection summarize evidence, and their inclusion does not mean that the interventions reviewed have been shown to be an effective prevention measure.
