Mo. Rev. Stat. § 199.180
A person found to have tuberculosis shall follow the instructions of the local board, shall obtain the required treatment, and shall minimize the risk of infecting others with tuberculosis. When a person with active tuberculosis, or a person who is a potential transmitter, violates the rules, regulations, instructions, or orders promulgated by the department of health or the local board, and is thereby conducting himself or herself so as to expose other persons to danger of infection, after having been directed by the local board to comply with such rules, regulations, instructions, or orders, the local board may institute proceedings by petition for commitment, returnable to the circuit court of the county in which such person resides, or if the person be a nonresident or has no fixed place of abode, then in the county in which the person is found. Strictness of pleading shall not be required and a general allegation that the public health requires commitment of the person named therein shall be sufficient.
