城市环境污染，是当今人类面临的一个重要问题，已经被世界各国所公认和重视。我国上至中央，下至区县的各级基层单位，都设有专门机关和专职人员，按照国家颁布的环境管理法规进行监督管理。唯有与人体接触频繁的各种公共用品，如公用电话、人民币、交通工具、理发工具、手等，怎样不受病源性微生物的污染或受到污染后如何及时清除、防疫，目前尚未被重视，列入议事日程。这是目前值得注意和重视的一大公共卫生研究课题。特别是在病毒性肝炎、艾滋病、肠道菌传染较为普遍存在，且在有发展趋势的城市，加强这方面的预防应用研究，显得更加迫切和突出。
Urban environmental pollution is an important issue facing mankind today, which has been recognized and valued by all countries in the world. Our country’s grass-roots units at all levels from the central government down to the districts and counties have specialized agencies and full-time staff to supervise and administer according to the environmental regulations promulgated by the state. Only with the frequent contact with the human body a variety of public goods, such as public telephone, RMB, transport, barber tools, hand, how to be free from pathogenic microorganisms or contaminated timely clearance, epidemic prevention, has not been valued, Included in the agenda. This is a major public health research project that deserves our attention and attention at present. Especially in the viral hepatitis, AIDS, intestinal infection is more prevalent, and in cities where there is a trend of development, to strengthen prevention and application research in this area, more urgent and prominent.
