After patients are seen by a healthcare provider, a "Self-isolation/Self-quarantine and Controlled Movement Agreed Order" is signed. Included in the 10-part agreement obtained by ABC News, it states, "I acknowledge that if I cannot or will not comply with all of the control measures listed . . . LMPHW shall obtain a court order from Jefferson County Circuit Court to enforce the terms of the agreed order."
