Classification: CPC G  A | IPC A  G

Claim 0:
1. A computer-implemented method comprising:
generating, by one or more processors, a contact graph for a user in a group of users in an area, based on a pre-defined distance measurement between the user and another user in a same timestamp during a pre-defined time period;
building, by one or more processors, a profile for the user based on the contact graph, the profile including a probability model corresponding to the contact graph to estimate an infection probability for the user;
calculating, by one or more processors, an initial route for the user from a first location to a second location in the area;
analyzing, by one or more processors, an infection risk for the user based on the profile and other users within a pre-defined distance to the user in the initial route; and
updating, by one or more processors, the initial route based on the analysis to minimize the risk to be infected.
