More than 3.65 million people have recovered.[8] Common symptoms include FEVER, COUGH, fatigue, shortness of breath, and loss of smell and taste.[5][6][13] While the majority of cases result in mild symptoms, some progress to acute respiratory distress syndrome (ARDS) possibly precipitated by CYTOKINE storm,[14] multi-organ FAILURE, septic shock, and blood clots.[15][16][17] The time from exposure to onset of symptoms is typically around five days, but may range from two to fourteen days.[5][18]
