And a more scientific treatment of the outbreak so far:
Clinical features of patients infected with 2019 novel coronavirus in Wuhan, China
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 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.

From that article:
The most 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 (coughing up blood) (two [5%] of 39), and diarrhoea (one [3%] of 38; table 1). More than half of patients (22 [55%] of 40) developed dyspnoea (labored breathing).
The median duration from illness onset to dyspnoea was 8·0 days (IQR 5·0–13·0). The median time from onset of symp-toms to first hospital admission was 7·0 days (4·0–8·0), to shortness of breath was 8·0 days (5·0–13·0), to ARDS was 9·0 days (8·0–14·0), to mechanical ventilation was 10·5 days (7·0–14·0), and to ICU admission was 10·5 days (8·0–17·0; figure 2).
The blood counts of patients on admission showed leucopenia (reduced white blood cell count)(white blood cell count less than 4×10â¹/L; ten [25%] of 40 patients) and lymphopenia (reduced lymphocytes, one of three types of white blood cells) (lymphocyte count <1·0×10â¹/L; 26 [63%] patients; table 2).
Comments in italics are mine, to translate medicalese a little.
