May a health director issue a standing order for isolation to a community partner to prevent someone suspected of being infected from leaving against medical advice and creating a public health risk?

Original question: "May the state health director or a local health director issue a 'standing order' for isolation to a community partner, such as a hospital, to prevent an individual suspected of being infected from leaving against medical advice and creating a risk to the public health?"

There is no authority to issue standing orders and such orders may well be an improper delegation of the public health official’s police power. The better practice would be for the health director to identify in advance other appropriate public officials who may exercise the isolation and quarantine authority when the director is unavailable and ensure that community providers have a means to reach such persons by telephone at any hour of any day. The person may issue an oral order over the telephone if necessary, and follow it with a written order as soon as practicable.
