An influenza pandemic--an outbreak of a novel influenza virus that spreads around the world--is a real threat. To predict the spread of an influenza pandemic across the whole of Japan, this study applies a real individual-based model (ribm) to the whole of Japan and simulates how a single case of influenza could spark pandemic influenza throughout Japan. We(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.
