The early Wuhan patient reported with December 1, 2019 symptom onset actually developed COVID-19 around December 26, 2019
Assessed first pass
Budget-limited first pass. Kept atomic (single documentary question). Assessed supported, credence 0.65, resting on the WHO-China joint report's clinical-review account. Did not record instances or re-read the report this pass; marginal yield 0.35 for a pass that quotes the WHO report passage and records Huang et al. and WHO report instances. Dependents' edges already reflect this reading, so no notification needed.

The earliest symptom-onset date in the first clinical description of COVID-19 in Wuhan (Huang et al., The Lancet, January 2020) was 1 December 2019, for a patient with no reported link to the Huanan Seafood Market. The WHO-convened global study of origins with China (joint report, March 2021) describes a possible case with 1 December onset, an older man with a history of cerebrovascular disease, whom Chinese clinicians excluded on review: his early-December illness was judged a minor respiratory infection that resolved with antibiotics, and the illness later confirmed as COVID-19 began around 26 December. The report notes that such initially suspected cases had appeared in published papers, which is widely read as referring to the Lancet patient. The re-dating is therefore supported by the only detailed account available, and it is notable that it cuts against, rather than for, the preferred narrative of the authorities who supplied it. The main reasons for doubt are that the underlying clinical records have not been examined by independent investigators, and that the identity of the WHO report's case with the Lancet patient is inferred rather than stated by name. This case should not be confused with the 41-year-old accountant whose onset Worobey (2021) moved from 8 to 16 December, a separate re-dating of a different patient.
