In time of epidemic or threatened epidemic, or when a dangerous communicable disease is unusually prevalent, the Board of Health, after a personal investigation by the members or executive officer thereof to establish the facts in the case, and not otherwise, may impose a quarantine on railroad cars or other public or private vehicles conveying persons, baggage or freight, or used for such purposes. The Board may make and enforce such rules and regulations as it deems prudent and necessary for the protection of the health of the people of the City, but the running of any train or car on any railroad or other means of conveyance shall not be prohibited. A true copy of such quarantine rules and regulations adopted by the Board shall be immediately furnished by it to the State Department of Health; thereafter, no change shall be made except by order of the State Department of Health or by the Board to meet a new and sudden emergency.
