Abstract: 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.

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.
