This evidence was often compiled very rapidly during a fast-moving response and should be viewed in this context. The paper presented here is the best assessment of the evidence at the time of writing, and the conclusions were formed on this basis. As new evidence or data emerges, SAGE updates its advice accordingly. Therefore, some of the information in this paper may have been superseded at a later date.
