Actual (reported)Correlation between registered coughs per person-hour and incidence of respiratory diseases
The investigators will run an ARIMA analysis with three parallel time series: aggregated incidence of respiratory diseases in the observed cohort, in the entire study area, and aggregated cough data.

All enrolled participants will be asked to install the acoustic surveillance software in their smartphones and use it to record night-time coughs for a minimum 30-day period.
A mobile app that runs in the background of smartphones and detects putative cough sounds.
Registry-reported names are shown in full. Names without a link have not yet been matched to a Syfrah profile.
Participants will be recruited in the Cendea de Cizur, a municipality composed by a cluster of villages south of the city of Pamplona, and the neighbouring town of Cizur Mayor, in the Comunidad Foral de Navarra (Spain), as well as in the different campuses of the University of Navarra. The 4,000 people living in the Cendea de Cizur are served by a public health center which receives 45,000 outpatients visits per year. Of these, approximately 12% are associated with respiratory diseases. The University of Navarra has over 11,000 registered students, 900 professors and over 600 other employees. Both the Cendea de Cizur and the University are served by the Clínica Universidad de Navarra, the largest private health center in the region, which provides medical care to an estimated population of over 100,000 people.
