It is the duty of the city health officer, upon the appearance of any dangerous, contagious or infectious disease within the city immediately to investigate all circumstances concerning such diseases, and to make a full report thereof as above required and at all times, promptly, to take such measures for the prevention, suppression and control of such diseases as may be needful and proper. He shall have the power to remove to and restrain in a pest house or isolation hospital or to quarantine or isolate any person sick with any dangerous, contagious or infectious disease until such person has thoroughly recovered and been disinfected; provided that no person shall be removed to or restrained in a pest house or isolation hospital until such person has been examined by the city health officer or a medical deputy. He shall also quarantine, isolate, restrain, vaccinate or disinfect any person or persons exposed to any dangerous, contagious or infectious disease in such a manner and for such time as he may deem best or the State Board of Health may direct. He shall disinfect any room, house or building and the contents thereof or any clothing, bedding, furniture or other articles that may be infected in such a manner that the danger of conveying any disease by such means is destroyed.
