Patient level records are not public information, and may be shared only with other public health authorities and co-investigators of a health study if they abide by the same confidentiality restrictions required by the Department of Health and Senior Services under sections 192.067, RSMo.

Statistical data can be released to such entities as local public health agencies, community planning partners, health care providers, and the general public in aggregate format. However, in some cases where aggregate data contains certain small numbers (termed small cell data) and may indirectly identify a patient (for example, one case of syphilis in a small rural county), data may be released in an alternate format (e.g., less than five cases, less than ten cases, etc.).
