First, we analyzed the group of COVID-19-related nervous system phenotypes, which includes loss of smell (anosmia), loss of taste (parageusia), and headache ( Figure 1 ). To further study the relation between different comorbidity phenotypes and disease outcomes, we survey the disease data from the literature and compared the incidences of specific comorbidity phenotypes in severe or non-severe COVID-19 patients. In severe disease patients, the incidence of diabetes or kidney failure was higher than that in non-severe patient groups (The X-axis is country/city, report date, number of cases). Based on the HP classification, we systematically analyzed 17 clinical phenotypes of COVID-19 in case reported.	./cache/cord-217201-lvefk7qx.txt	./txt/cord-217201-lvefk7qx.txt
