Maternity and child health care in urban China

In China the effort to develop maternal and child health (MCH) care has been ongoing. Initially, attention was directed primarily to promulgating a modern method of delivery in an effort neonatal tetanus and puerperal fever. The next stage was the systematic management of MCH care.
