BACKGROUND Real-time surveillance is fundamental for effective control of disease outbreaks, but the official sentinel surveillance in Japan collects information related to disease activity only weekly and updates it with a 1-week time lag. OBJECTIVE To report on a prescription surveillance system using electronic records related to prescription drugs(More)
Objectives In Japan, a rubella outbreak occurred from early 2012 to late 2013, primarily among adult males aged 20-49 years. We conducted this study to predict the number of congenital rubella syndrome (CRS) cases in Japan in 2014. Methods The probability of CRS when a pregnant woman is infected with rubella depends on the gestational age of the fetus. The(More)
BACKGROUND Contact patterns and vaccination decisions are fundamental to transmission dynamics of infectious diseases. We report on age-specific contact patterns in Japan and their effect on influenza vaccination behaviour. METHODS Japanese adults (N=3146) were surveyed in Spring 2011 to assess the number of their social contacts within a 24 h period,(More)
Much discussion has surrounded the association between the administration of neuraminidase inhibitors (NI) and severe abnormal behaviors, including sudden running away and jumping from a high place, which can be life-threatening if no one intervenes. Using data on the number of abnormal behaviors and patients who had been prescribed NI in Japan, we(More)
Rubella usually is a mild, febrile rash illness in children and adults; however, infection early in pregnancy, particularly during the first 16 weeks, can result in miscarriage, stillbirth, or an infant born with birth defects (i.e., congenital rubella syndrome [CRS]) (1). As of 2013, goals to eliminate rubella have been established in two World Health(More)
Syndromic surveillance, including prescription surveillance, offers a rapid method for the early detection of agents of bioterrorism and emerging infectious diseases. However, it has the disadvantage of not considering definitive diagnoses. Here, we attempted to definitively diagnose pathogens using polymerase chain reaction (PCR) immediately after the(More)
reproduction in any medium, provided the original work is properly cited. Objective So far, it is difficult to show the incidence rate of influenza in the official sentinel surveillance in Japan. Hence we construct the system which record infectious diseases at schools, kindergartens, and nursery schools, and then can show the accurate incidence rate of(More)
