We can use more real-time daily surveillance of infectious diseases other than PS and NOSSID, which were used for this study. For example, Nursery School Absenteeism Surveillance System ((N)SASSy) has been monitoring the health situation, diagnosed diseases or symptoms, of more than five million students or nursery school kids every day. It is a computerized system comprising a network of information shared among concerned organizations and individuals [10] [11] [12] . We can therefore use (N)SASSy as a form of syndromic surveillance in Japan. In short, all information related to children's health conditions is integrated in (nursery) schools. It was developed by a research group headed by Dr. Ohkusa, one author of this paper. It has been funded by the MHLW since 2007. It has retained its copyright to the present day.
