It is now known as apandemic and a global crisis due to rapid human‑to‑human transmission with the vast expansionthat has affected almost all countries. The primary source of the disease is still unknown, but it ispossible that the virus was transmitted through bat to an intermediate host and then to humans.The main and early symptoms of COVID‑19 infection are fatigue, fever, dry cough, myalgia, anddyspnea. The incubation period of the disease is about 2–14 days, which is one of the importantparameters for planning to prevent disease outbreak. PT‑polymerase chain reaction test is used todiagnose the disease; chest computed tomography scan, chest X‑ray, blood tests, and symptomsare also very helpful in diagnosing the disease. There is a strong emphasis on controlling infectionsand hand hygiene to prevent the transmission of the disease. There is not enough knowledge aboutthis disease yet, and there are no specific vaccines or medications available to prevent and treat thisdisease. The current review study uses articles indexed on databases of Embase, Elsevier, PubMed,and World Health Organization and Centers for Disease Control and Prevention, and keywords ofcoronavirus, COVID‑19, acute respiratory distress syndrome and China.
