From the Clinical Characteristics: "In the case of an emerging infectious disease such as COVID-19 [coronavirus disease 2019], it can be difficult for medical practitioners to recognise and diagnose the disease because of the relative lack of knowledge around the presentation of the disease. This section reviews the literature that describe the clinical characteristics of patients with COVID-19, which will hopefully provide health authorities and medical practitioners with a better idea of how COVID-19 presents globally. Where possible, we compare the situation in Singapore to the global situation. Information about Singapore's COVID-19 patients are taken from the case series on the first 18 patients diagnosed between 23 January and 3 February 2020, with onset of symptoms occurring between 14 and 30 January 2020 All of these cases had a travel history to Wuhan city within 14 days prior to developing symptoms."
