The United States puts immediate quarantines on imported products if a contagious disease is identified and can be traced back to a certain shipment or product. All imports will also be quarantined if the disease appears in other countries. According to Title 42 U.S.C. §§264 and 266 , these statutes provide the Secretary of Health and Human Services peacetime and wartime authority to control the movement of people into and within the United States to prevent the spread of communicable disease.
