the at least one processor is configured to execute the instructions to specify, as the high-risk user, each user who visited the outbreak region during a predetermined period as the date and time if the infected user visited is to be a reference date and time.

7 . The health management device according to claim 5 , wherein the at least one processor is configured to execute the instructions to:

determine whether or not one or more of a shape and color of a facial area is abnormal, using a face image of the user;

determine whether or not a body temperature of the user is equal to or greater than a threshold value; and

determine, by using a machine learning model trained to output whether or not an initial symptom of the disease appearing on a face in response to an input of the face image, whether or not the initial symptom is appeared using the face image of the user,

wherein using respective results of determining whether or not whether or not one or more of a shape and color of a facial area is abnormal, determining whether or not a body temperature of the user is equal to or greater than a threshold value, determining whether or not the initial symptom is appeared, the symptom of the user is specified, a probability that the user is infected with the disease is calculated, and the disease name is estimated.

8 . The health management device according to claim 1 , wherein the environmental information includes one or more of:
