On March 19, Commissioner John W. Hellerstedt, M.D., of the Texas Department of State Health Services, declared a state of public health disaster for the entire state of Texas. The authority to do so and explanation of what that means can be explored in the Communicable Disease Prevention and Control Act, which is located in Texas Health and Safety Code Chapter 81, Communicable Diseases. The legislation was enacted by SB 1064, 68R. A few years later, the Act was added to the Health and Safety Code as part of statutory revision. (Previously it was found in VACS Art. 4419b-1.)
