Emerging and reemerging diseases pose global challenges for public health. Pneumonia of unknown origin, given the name COVID-19, began in China in December 2019. On March 11, 2020, the WHO declared it to be a pandemic. Currently, the disease is booming rapidly and impacting the well-being of people and the economy of countries globally. Observational studies have somewhat highlighted clinical findings of the disease, but there are still no decisive data about its global trends. The purpose of this review is to bring to light the huge disparities in the clinical presentation of the disease among countries. The data for this review were obtained from studies pertaining to clinical, laboratory, and imaging features obtained from various journals. It was found that occurrence of the most frequently seen features ranged as – fever (98%–35%), cough (88%–25%), dyspnea (88%–4.8%), and sore throat (61%–8%). A definite reason for this is still obscure. This calls for more conclusive studies to investigate the possible causes of these trends. This might go a long way in increasing our understanding of the disease and improve its diagnosis and treatment.
