Abstract

Background A recent cluster of pneumonia cases in Wuhan, China, was caused by a novel betacoronavirus, the 2019 novel coronavirus (2019-nCoV). We report the epidemiological, clinical, laboratory, and radiological characteristics and treatment and clinical outcomes of these patients. Methods All patients with suspected 2019-nCoV were admitted to a designated hospital in Wuhan. We prospectively collected and analysed data on patients with laboratory-confirmed 2019-nCoV infection by real-time RT-PCR and next-generation sequencing. Data were obtained with standardised data collection forms shared by WHO and the International Severe Acute Respiratory and Emerging Infection Consortium from electronic medical records. Researchers also directly communicated with patients or their families to ascertain epidemiological and symptom data. Outcomes were also compared between patients who had been admitted to the intensive care unit (ICU) and those who had not. Findings By Jan 2, 2020, 41 admitted hospital patients had been identified as having laboratory-confirmed 2019-nCoV infection. Most of the infected patients were men (30 [73%] of 41); less than half had underlying diseases (13 [32%]), including diabetes (eight [20%]), hypertension (six [15%]), and cardiovascular disease (six [15%]). Median age was 49·0 years (IQR 41·0-58·0). 27 (66%) of 41 patients had been exposed to Huanan seafood market. One family cluster was found. Common symptoms at onset of illness were fever (40 [98%] of 41 patients), cough (31 [76%]), and myalgia or fatigue (18 [44%]); less common symptoms were sputum production (11 [28%] of 39), headache (three [8%] of 38), haemoptysis (two [5%] of 39), and diarrhoea (one [3%] of 38). Dyspnoea developed in 22 (55%) of 40 patients (median time from illness onset to dyspnoea 8·0 days [IQR 5·0-13·0]). 26 (63%) of 41 patients had lymphopenia. All 41 patients had pneumonia with abnormal findings on chest CT. Complications included acute respiratory distress syndrome (12 [29%]), RNAaemia (six [15%]), acute cardiac injury (five [12%]) and secondary infection (four [10%]). 13 (32%) patients were admitted to an ICU and six (15%) died. Compared with non-ICU patients, ICU patients had higher plasma levels of IL2, IL7, IL10, GSCF, IP10, MCP1, MIP1A, and TNFα. Interpretation The 2019-nCoV infection caused clusters of severe respiratory illness similar to severe acute respiratory syndrome coronavirus and was associated with ICU admission and high mortality. Major gaps in our knowledge of the origin, epidemiology, duration of human transmission, and clinical spectrum of disease need fulfilment by future studies.

  • Myocardial damage similar to myocarditis was one of the first complications reported from patients with COVID-19 in Wuhan, China, at the beginning of the pandemic.

    “Myocardial damage similar to myocarditis was one of the first complications reported from patients with COVID19 in Wuhan, China, at the beginning of the pandemic.”

    From COVID-19, Myocarditis and Pericarditis (2023) · cites this paper as [66]

    The Results report acute cardiac injury as a complication in five of 41 patients in the early Wuhan cohort. The Methods define cardiac injury by elevated biomarkers or new ECG or echocardiographic abnormalities; the paper does not characterize it as myocarditis-like. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • The most common clinical presentation of severe COVID-19 is viral pneumonia featuring fever, cough, dyspnoea, hypoxemia, and bilateral infiltrates on chest radiographs.

    “Evidence shows that the most common clinical presentation of severe COVID-19 is viral pneumonia featuring fever, cough, dyspnoea, hypoxemia, and bilateral infiltrates on chest radiographs [2–4].”

    From Effects of short-term breathing exercises on respiratory recovery in patients with COVID-19: a quasi-experimental study (2022) · cites this paper as [2]

    The Results report pneumonia in all 41 patients, frequent fever and cough, dyspnoea in 12 of 13 ICU patients, and bilateral chest-radiograph involvement in all 13. The paper reports refractory hypoxaemia in only two patients and describes a small hospitalised cohort; it does not establish that the full combination is the most common presentation of severe COVID-19 generally. (LLM, conf=0.84)

  • Coronavirus disease 2019 (COVID-19) is a highly infectious respiratory tract disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

    “Coronavirus disease 2019 (COVID-19) is a highly infectious respiratory tract disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) [1, 2].”

    From Effects of short-term breathing exercises on respiratory recovery in patients with COVID-19: a quasi-experimental study (2022) · cites this paper as [2]

    The Introduction identifies 2019-nCoV in lower respiratory tract samples from patients with pneumonia, supporting the claim that a novel coronavirus caused respiratory disease. The Discussion says evidence indicated human transmission but describes efficient human transmission as a concern, not an established finding; it does not support calling the disease “highly infectious.” The paper uses the earlier name 2019-nCoV rather than SARS-CoV-2. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • COVID-19 patients rapidly deteriorate to acute respiratory failure.

    “This is because the respiratory problems experienced by patients with COVID-19 significantly differ from other respiratory conditions (e.g., dry cough is common [4, 19]) and COVID-19 patients' rapid deterioration to acute respiratory failure [2–4].”

    From Effects of short-term breathing exercises on respiratory recovery in patients with COVID-19: a quasi-experimental study (2022) · cites this paper as [2]

    The Discussion reports that patients with severe illness developed acute respiratory distress syndrome (ARDS), in some cases as soon as two days after admission. The Results show ARDS in 12 of 41 patients (29%). This supports rapid deterioration in a subset of the hospitalized cohort, but not the unqualified implication that COVID-19 patients generally deteriorate to acute respiratory failure. (LLM, conf=0.86)

  • Severe respiratory symptoms can cause respiratory failure (ARDS), which can lead to death unless promptly managed using ventilation at ICU.

    “As mentioned before, severe respiratory symptoms can cause respiratory failure (ARDS), which can lead to death unless promptly managed using ventilation at ICU [2, 3, 6].”

    From Effects of short-term breathing exercises on respiratory recovery in patients with COVID-19: a quasi-experimental study (2022) · cites this paper as [2]

    The Discussion reports that severely ill patients developed ARDS and required ICU admission and oxygen therapy; the Results report mechanical ventilation in four patients and six deaths. The paper does not establish that prompt ICU ventilation prevents death or that death follows unless it is provided. (LLM, conf=0.86)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
