A new coronavirus, designated COVID-19, emerged in Wuhan, China, in December 2019, causing respiratory, digestive and systemic problems that affect human health. In symptomatic patients, the clinical manifestations of the disease usually begin within a week, and consist of fever, cough, nasal congestion, fatigue and airway problems, which can lead to pneumonia. The virus also appears in patients who do not have symptoms, and it is quite difficult to quantify them. In this work, a review of the virological characteristics of COVID-19 has been carried out, both of its clinical sign, its diagnosis and its treatment.
