Abstract: A method includes identifying a first user device associated with local status information indicating a need for medical attention and establishing a biological threat event for the first user device. The method further includes establishing event timeline information of the biological threat event to include time information of historical geographic location coordinate information of the first user device. The method further includes identifying a second user device potentially associated with the biological threat event based on time information of historical geographic location coordinate information of the second user device. The method further includes identifying a third user device potentially associated with the biological threat event based on the time information of the historical geographic location coordinate information of the second user device and time information of historical geographic location coordinate information of the third user device.

Abstract: A method includes identifying a first user device potentially associated with a biohazard and identifying a geographic area associated with the biohazard based on previous location information of the first user device. The method further includes identifying another user device potentially associated with the biohazard based on the geographic area associated with the biohazard and previous location information of the other user device. The method further includes issuing a safety notification to the other user device, where the safety notification includes one or more of the geographic area associated with the biohazard, a safety status request, a safety status level of the first user device, a subset of the previous location information of the first user device, and a subset of the previous location information of the other user device.

Abstract: A method includes identifying a first user device potentially associated with a biological threat event and establishing a relevant time period of the biological threat event. The method further includes identifying geographic location coordinates associated with the biological threat event based on the relevant time period of the biological threat event and geographic location coordinate information of the first user device for the relevant time period. The method further includes identifying a second user device potentially associated with the biological threat event based on the geographic location coordinates associated with the biological threat event and geographic location coordinate information of the second user device for the relevant time period. The method further includes issuing status information to the second user device, where the status information includes the relevant time period of the biological threat event.

Abstract: A method begins with identifying a geographic area associated with an adverse condition and identifying a plurality of user devices of a social network potentially associated with the identified geographic area. The method continues with issuing a safety notification to the plurality of user devices. The method continues with receiving a first safety status response from a first user device and a second safety status response from a second user device, where the responses include location information of a first and second safe location. The method continues with issuing evacuation information to at least some of the plurality of user devices based on the location information of the first and second safe locations.
