Coronavirus disease 2019 (COVID-19) is spread through large droplets produced during coughing and sneezing by symptomatic patients as well as asymptomatic individuals before starting of their symptoms. The incubation period of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection is assumed to be 14 days succeeding exposure, mostly around 4 to 5 days. Individuals of all ages can acquire SARS-CoV-2 infection, although middle age and older individuals are the majority. The usual clinical characteristics involve fever, dry cough, fatigue, sore throat, rhinorrhea, conjunctivitis headache, myalgia, dyspnea, nausea, vomiting and diarrhea.

In a subgroup of cases, by the end of the first week COVID-19 disease can develop to pneumonia, pulmonary failure and death. Aim is here to discuss the COVID-19 disease beginning from virology, epidemiology and continuing with clinical manifestations, diagnosis, its complications and to finish with available therapeutic options and conclusion.
