{"doi":"10.1093/bmb/ldad016","title":"Long COVID: what is known and what gaps need to be addressed","abstract":"INTRODUCTION: Long COVID is a chronic condition that follows after acute COVID-19 and is characterized by a wide range of persistent, cyclic symptoms. SOURCES OF DATA: PubMed search for publications featuring 'Long COVID' or 'post-acute sequelae of COVID-19'. AREAS OF AGREEMENT: Long COVID occurs frequently post-acute COVID-19, with a majority of people experiencing at least one symptom (such as cough, fatigue, myalgia, anosmia and dyspnoea) 4 weeks after infection. AREAS OF CONTROVERSY: The specific symptoms and the minimum duration of symptoms required to be defined as Long COVID. GROWING POINTS: There is a consistent reduction in Long COVID incidence amongst vaccinated individuals, although the extent of this effect remains unclear. AREAS TIMELY FOR DEVELOPING RESEARCH: There is an urgent need to understand the causes of Long COVID, especially extreme fatigue more than 6 months after infection. We must understand who is at risk and whether reinfections similarly risk Long COVID.","journal":"British Medical Bulletin","year":2023,"id":323411,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":37,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.8738,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2023-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":1038233,"name":"Mark R.
