Public Health Information Systems (PHIS)

Public Health information systems (PHIS) are used by public health agencies (PHA) to collect, manage, store, and transmit STD data. CDC is leveraging HIS to better understand the impact of STDs in the United States and improve disease surveillance reporting.

In the United States, there are seven main information systems currently used by states, territories, and project areas. All the systems are web-based.
