Description: CDC works to save lives and protect people during major public health events. In an effort to support these processes, CDC established CTS, which is maintained within the Division of Informatics Solutions and Operations (DISO), in the Public Health Informatics and Technical Program Office (PHITPO). CTS consists of four system components, which interoperate to improve communications and event response efficiency while still functioning independently, recognizing the unique requirements and use cases for each system. Collectively, the data consolidated from these systems can show population coverage, numbers of untreated individuals, drug and equipment shortages, need for resupply and more. The web-based applications are deployed centrally at CDC and use the CDC's secure data access method for security.
