Coronavirus disease 2019 (COVID-19), pandemic caused by the novel coronavirus SARS-CoV-2, has caused marked morbidity and mortality globally. The clinical spectrum of COVID-19 can be classified as asymptomatic, mild, moderate and severe disease. Majority of the symptomatic patients complain of fever, dry cough, sore throat and shortness of breath, while others present with non-specific symptoms like altered sense of smell or taste, myalgia, lethargy, diarrhoea and other gastrointestinal disturbances.


Though COVID-19 mainly affects the respiratory system, disease may cause widespread systemic and organ specific symptoms involving gastrointestinal, neurological, cardiovascular, immunological, cutaneous, hematological and coagulation systems. Minority of patients present with large vessel strokes, rare neurological syndromes like Guillain-Barre syndrome and Miller Fisher syndrome, which may be the sole manifestation of the disease. Some of the clinical presentations and pathogenesis of COVID are yet to be unraveled.
