An internet-based disease monitoring system includes a patient-operated device, such as a spirometer, that includes a sensor producing input signals responsive to a patient condition, and a transmitter coupled to the sensor and producing output signals corresponding to the input signals produced by the sensor. A mobile communication device responsive to receipt of the output signals from the patient-operated device forwards the output signals to a predetermined network address. A remote server at the network address is responsive to the output signals received from the mobile communication device and analyzes the output signals and produces analysis signals representing the results of the analysis. The remoter server further transmits the results of the analysis to predetermined recipients associated with the patient-operated device.
