Detecting a respiratory tract infection (RTI) based on changes in coughing sounds, which can provide an early warning of infection with a disease like COVID- 19 , as well as indications of its progression and severity. In one embodiment, the system includes smartglasses, with sensors mounted thereto, which include an acoustic sensor mounted at a fixed position relative to a user's head, and a movement sensor. A computer receives current measurements of the user, taken with the sensors, while there were head movements that characterize coughing, and also earlier measurements of the user, taken with the sensors, while the user had a known extent of the RTI and while there were head movements that characterize coughing. The computer detects a change relative to the known extent of the RTI based on a difference between the current measurements and the earlier measurements. |
