Interestingly, although about half of the states had relatively clear language related to how and when information could be disclosed by public health officials, some of these states also had statutes pertaining explicitly to HIV, STIs, and tuberculosis. We also found that although the statutory language seemed clear on its face, there were almost no court cases, very few definitions, and few regulations to guide interpretation of the statutes. This finding may be contributing to confusion and uncertainty among public health officials about how and when public health information should be or is disclosed.
