The school-based surveillance system monitors principally common communicable diseases among school children. Elementary schools are places of high population density and school children tend to have lower resistance to diseases. The outbreak of a disease in class can easily reach epidemic proportion. For the purpose of effectively detecting and controlling the spread of communicable diseases on school grounds, the Centers for Disease Control (CDC) launched a pilot program for schools to monitor and report infectious diseases since February 2001. Starting out with 20 reporting schools, there are now 634 elementary schools taking part in the program that aims to grasp the long-term trends of communicable diseases in school children, in order to facilitate early detection of pathogen and prevention of epidemics. |
