  It is shown that various symptoms could remain in the stage of post-acute
sequelae of SARS-CoV-2 infection (PASC), otherwise known as Long COVID. A
number of COVID patients suffer from heterogeneous symptoms, which severely
impact recovery from the pandemic. While scientists are trying to give an
unambiguous definition of Long COVID, efforts in prediction of Long COVID could
play an important role in understanding the characteristic of this new disease.
Vital measurements (e.g. oxygen saturation, heart rate, blood pressure) could
reflect body's most basic functions and are measured regularly during
hospitalization, so among patients diagnosed COVID positive and hospitalized,
we analyze the vital measurements of first 7 days since the hospitalization
start date to study the pattern of the vital measurements and predict Long
COVID with the information from vital measurements.
