Introduction So as to develop more effective countermeasures against influenza, timely and precise information about influenza activity at schools, kindergartens, and nursery schools may be helpful. At the Infectious Diseases Surveillance Center of the National Institute of Infectious Diseases, a School Absenteeism Surveillance System (SASSy) has been in operation since 2009. SASSy monitors the...

Advances in surveillance science have supported public health agencies in tracking and responding to disease outbreaks. Increasingly, epidemiologists have been tasked with interpreting multiple streams of heterogeneous data arising from varied surveillance systems. As a result public health personnel have experienced an overload of plots and charts as information visualization techniques have n...

Many aberration detection algorithms are used in infectious disease surveillance systems to assist in the early detection of potential outbreaks. In this study, we explored a novel approach to adjusting aberration detection algorithms to account for the impact of seasonality inherent in some surveillance data. By using surveillance data for hand-foot-and-mouth disease in Shandong province, Chin...

Background: Dengue, chikungunya, and Zika viruses are emerging infectious disease threats wherever suitable vectors, hosts, and habitat are present. The aim of the present study was to use the bioagent transport and environmental modeling system (BioTEMS) to identify the potential for arbovirus-infected Aedes species to invade the Chabahar area in southeastern Iran. Methods: ArcGIS geospatial a...

OBJECTIVE Research studies show that social media may be valuable tools in the disease surveillance toolkit used for improving public health professionals' ability to detect disease outbreaks faster than traditional methods and to enhance outbreak response. A social media work group, consisting of surveillance practitioners, academic researchers, and other subject matter experts convened by the...

in the present study, 360 male day-old broiler chicks were used to determine the effect of mixed livevaccines of newcastle disease (nd) and infectious bronchitis (ib) on serum and local antibody responses toib. chicks were randomly divided into 12 treatment groups of 3 replicates and reared for 40 days on floorpens. groups 1 to 5 received mixed nd and ib vaccine. groups 7 to 11 received ib vacc...

introduction: regarding the cross contamina-tion, prevention from infection is of high prior ity. the aim of this research was assessment of knowledge and attitude of dental students toward infection control in endodontics depart ment of faculty of dentistry, babol uni versity of medi cal sciences. materials and methods: the study was accom plished among 8th, 10th and 12th grade dental students...

infectious bursal disease virus (ibdv) infects young chickens and causes serious lose to the poultry industry, worldwide. previous attempts using purified bacterially expressed ibdv vp2 failed to elicit a protective immune response to the virus. this study was designed to investigate if the initial expressed protein contained neutralizing epitopes but became nonfunctional during purification st...

the main purpose of this paper has been to discuss the effects of psychological stress and other environmental factors on incidence of diseases. we were specifically concerned with stress that increased susceptibility of uninfected hosts when exposed to infection. if such stresses also reduced resources, fecundity and/or survivorship, there was a reduction in the host carrying capacity. in addi...

Formed in 2008, the Southern African Centre for Infectious Disease Surveillance (SACIDS) is a One Health consortium of academic and research institutions involved with infectious diseases of humans and animals. Operating in partnership with world-renowned centres of research in industrialised countries, its mission is to harness innovations in science and technology for improving southern Afric...
