A non-contact body temperature detection system of a vehicle includes: a thermography camera configured to generate an image of a user within a passenger cabin of the vehicle; a head detection module configured to determine a first area of the image including a head of the user; an eye detection module configured to determine a second area of the first area of the image including an eye of the user; a tear duct detection module configured to determine a third area of the second area of the image including a tear duct of the user; a temperature module configured to determine a body temperature of the user based on pixels of the third area of the image; and an indicator module configured to indicate whether the user has an elevated body temperature when the body temperature of the user is greater than a temperature threshold.
