          Abstract

          Background

          We aimed to investigate the epidemiological and clinical features, and medical care-seeking process of patients with the 2019 coronavirus disease (COVID-19) in Wuhan, China, to provide useful information to contain COVID-19 in other places with similar outbreaks of the virus.

          Methods

          We collected epidemiological and clinical information of patients with COVID-19 admitted to a makeshift Fangcang hospital between 7 and 26 February, 2020. The waiting time of each step during the medical care-seeking process was also analysed.

          Results

          Of the 205 patients with COVID-19 infection, 31% had presumed transmission from a family member. 10% of patients had hospital-related transmission. It took as long as a median of 6 days from the first medical visit to receive the COVID-19 nucleic acid test and 10 days from the first medical visit to hospital admission, indicating early recognition of COVID-19 was not achieved at the early stage of the outbreak, although these delays were shortened later. After clinical recovery from COVID-19, which took a mean of 21 days from illness onset, there was still a substantial proportion of patients who had persistent SARS-CoV-2 infection.

          Conclusions

          The diagnostic evaluation process of suspected patients needs to be accelerated at the epicentre of the outbreak and early isolation of infected patients in a healthcare setting rather than at home is urgently required to stop the spread of the virus. Clinical recovery is not an appropriate criterion to release isolated patients and as long as 4 weeks' isolation for patients with COVID-19 is not enough to prevent the spread of the virus.

          Abstract

          Early identification and isolation of infected patients in a healthcare setting rather than at home is urgently required to stop the spread of SARS-CoV-2. Clinical recovery is not an appropriate criterion to release isolated patients. https://bit.ly/3dXKBLV

          Clinical features of patients infected with 2019 novel coronavirus in Wuhan, China

          Summary 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.

            A Novel Coronavirus from Patients with Pneumonia in China, 2019

            Summary In December 2019, a cluster of patients with pneumonia of unknown cause was linked to a seafood wholesale market in Wuhan, China. A previously unknown betacoronavirus was discovered through the use of unbiased sequencing in samples from patients with pneumonia. Human airway epithelial cells were used to isolate a novel coronavirus, named 2019-nCoV, which formed a clade within the subgenus sarbecovirus, Orthocoronavirinae subfamily. Different from both MERS-CoV and SARS-CoV, 2019-nCoV is the seventh member of the family of coronaviruses that infect humans. Enhanced surveillance and further investigation are ongoing.

              Clinical Characteristics of 138 Hospitalized Patients With 2019 Novel Coronavirus–Infected Pneumonia in Wuhan, China

              In December 2019, novel coronavirus (2019-nCoV)-infected pneumonia (NCIP) occurred in Wuhan, China. The number of cases has increased rapidly but information on the clinical characteristics of affected patients is limited.
