A. The department, or local health authority may isolate or quarantine a person or group of persons through a written directive without first obtaining a written order from the court if any delay in the isolation or quarantine of the person would pose an immediate and serious threat to the public health. The directive shall:

1. 1. Specify the identity of the person or persons subject to isolation or quarantine, the premises subject to isolation or quarantine, the date and time at which isolation or quarantine commences, the suspected highly contagious and fatal disease, if known, and that a state of emergency has been declared by the governor.
2. 2. Be given to the person or persons to be isolated or quarantined. If the directive applies to groups of persons and it is impractical to provide individual copies, it may be posted in a conspicuous place in the isolation or quarantine premises.

B. Within ten days after issuing the written directive, or when any delay in the isolation or quarantine of a person or group of persons will not pose an immediate and serious threat to the public health, the department or local health authority shall file a petition for a court order authorizing the initial or continued isolation or quarantine of a person or group of persons. The petition shall specify the following:

1. 1. The identity of the person or group of persons subject to isolation or quarantine.
2. 2. The premises subject to isolation or quarantine.
3. 3. The date and time at which isolation or quarantine commences.
4. 4. The suspected contagious disease, if known.
5. 5. A statement of compliance with the conditions and principles for isolation and quarantine.
6. 6. A statement of the basis on which isolation or quarantine is justified pursuant to this article.

G. A court order authorizing isolation or quarantine may do so for a period not to exceed thirty days. The order must:

1. 1. Identify the isolated or quarantined person or group of persons by name or shared or similar characteristics or circumstances.
2. 2. Specify factual findings warranting isolation or quarantine pursuant to this article, including any conditions necessary to ensure that isolation or quarantine is carried out within the stated purposes and restrictions of this article.
3. 3. Be served on an affected person or group of persons in accordance with the rules of civil procedure.

N. In any proceedings brought pursuant to this section, to promote the fair and efficient operation of justice and having given due regard to the rights of the affected persons, the protection of the public's health, the severity of the emergency and the availability of necessary witnesses and evidence, the court may order the consolidation of individual claims into groups of claims if:

1. 1. The number of persons involved or to be affected is so large as to render individual participation impractical.
2. 2. There are questions of law or fact common to the individual claims or rights to be determined.
3. 3. The group claims or rights to be determined are typical of the affected person's claims or rights.
4. 4. The entire group will be adequately represented in the consolidation.
