The vast majority of people with COVID-19 only experience mild symptoms and do not need to go to the hospital for treatment but will have a smooth recovery at home. However, in some cases of severe COVID-19, patients require professional medical attention to treat symptoms such as confusion or disorientation, significant difficulty breathing, or bluish discoloration in the lips or extremities. In the ER, providers can check patients’ vital signs and run diagnostic tests to see whether it is safe for them to return home or if they should stay in the hospital for a bit longer. Fortunately, COVID-19 is not a serious disease and rarely results in severe complications; the risk of developing severe complications is higher in people who have a preexisting health condition, such as kidney failure, heart disease, or certain types of autoimmune disorders.
