N.H. Rev. Stat. § 141-C:1
The outbreak and spread of communicable disease cause unnecessary risks to health and life, interfere with the orderly workings of business, industry, government, and the process of education, and disrupt the day-to-day affairs of communities and citizens. Because the control of communicable disease may be attained by personal actions, the timely intervention of medical practices, and cooperation among health care providers, federal, state, and municipal officials, and other groups and agencies, it is hereby declared to be the policy of this state that communicable diseases be prevented, and that such occurrences be identified, controlled, and, when possible, eradicated at the earliest possible time by application of appropriate public health measures and medical practices.
