Physiological conditions of a plurality of individuals are monitored by using signals provided by sensors on each individual. Each individual has, positioned in close proximity to the individual, one or more sensors for sensing a physiological condition of the individual. A control module is capable of communicating with an external communication station and with the sensors. A wireless networked communication link is established between the control module and the external communication station. Indications of the physiological conditions for a plurality of individuals or physiological conditions derived from the physiological sensors, are transmitted on the wireless networked communication link to the external communication station.
