Surveillance is critical for both early detection and a timely public health response to infectious diseases. Electronic information systems have been widely adopted by pharmacies in Japan. The aim of this study is to evaluate the feasibility of using prescription data for influenza surveillance in Japan to facilitate the development of a daily reporting(More)
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)
The Infectious Disease Surveillance Center, National Institute of Infectious Diseases, Japan, has developed a fully automatic system for daily reporting of ILI (influenza-like illness) patients prescribed Oseltamivir and Zanamivir. The system collected data on the number of prescriptions from approximately 3,350 pharmacies, which account for almost 7% of(More)
A seventh round behavioral and serological surveillance found that the HIV epidemic had remarkably increased to 7% among intravenous drug users (IDU) in Central Bangladesh, indicating the urgent need to increase prevention. The main purposes of this study were to find out, by collecting data and the necessary information from sero-surveillances, published(More)
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)
OBJECTIVE Immunization for varicella is not currently included in routine immunizations in Japan. This study was conducted to assess test its cost-effectiveness when it becomes a routine. METHODS We surveyed and collected information for the year beginning 15th June 2004 in one area. Almost all 11 pediatric clinics or hospitals in the area cooperated in(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)
Currently, an individual-based model is a basic tool for creating a plan to prepare for the outbreak of pandemic influenza. However, even if we can construct the model as finely as possible, it cannot mimic the real world precisely. Therefore, we should use real data for transportation modes and locations, and simulate the diffusion of an infectious disease(More)
OBJECTIVE Mumps immunization is not included in routine immunization in Japan. We measured the cost-effectiveness of routine immunization. METHODS We surveyed outpatients prospectively from June 15, 2004, for 19 months in an area with a population of 100,000. Almost all of the 11 pediatric clinics and hospitals in this area cooperated. In 2006, we(More)
