BACKGROUND Malaria continues to be a major cause of infectious disease mortality in tropical regions. However, deaths from malaria are most often not individually documented, and as a result overall understanding of malaria epidemiology is inadequate. INDEPTH Network members maintain population surveillance in Health and Demographic Surveillance System sites across Africa and Asia, in which ind...
The present paper reviews the studies of populations living in high background radiation areas (HBRA). Past studies have shown that high background radiation has been repeatedly shown to increase the frequency of chromosome aberrations in the circulating lymphocytes of exposed persons, but its carcinogenic effect is still unproven. A further area of research is whether long term exposure to bac...
BACKGROUND Literature is limited on the effects of high prevalence HIV on fertility in the absence of treatment, and the effects of the introduction of sustained access to antiretroviral therapy (ART) on fertility. We summarize fertility patterns in rural northeast South Africa over 21 years during dynamic social and epidemiological change. METHODS We use data for females aged 15-49 from the ...
The purpose of the study was to determine the utility of general population health surveillance data for evaluating broad policy changes that relate to health promotion. Data were drawn from the United States (US) Behavioral Risk Factor Surveillance System (BRFSS) for one US state, California. Because these data are collected frequently and continually, a quasi-experimental approach to the eval...
Cost-effective surveillance strategies are needed for efficient responses to biological invasions and must account for the trade-offs between surveillance effort and management costs. Less surveillance may allow greater population growth and spread prior to detection, thereby increasing the costs of damages and control. In addition, surveillance strategies are usually applied in environments un...
conclusions addressing and removing explainable patterns of syndromic data on meningitis is necessary to timely and accurately detection of meningitis epidemics. it was concluded that decomposition methods had better performance compared to the model based ones. background meningitis is one of the most disturbing infectious diseases due to mortality, morbidity and its ability to cause epidemic....
lobesia botrana (denis & schiffermüller) (lepidoptera: tortricidae), is an important vineyard-pest in the european and mediterranean areas and it was recently described in argentina and chile. since knowledge on the l. botrana phenology on argentina is still limited, the objective of this study was to develop a phenological model to predict voltinism of l. botrana in argentina through a reg...
Background: Surgical wound infection surveillance is an important facet of hospital infection control processes. There are several surveillance methods for surgical site infections. The objective of this study is to evaluate the accuracy of two different surgical site infection surveillance methods. Methods: In this prospective cross sectional study 3020 undergoing surgey in general surgical w...
Background and Objectives: The Haemophilus influenzae (Hib) conjugate vaccine (HibCV) using a pentavalent formulation was introduced to the Iranian routine immunization program from November 2014. Iran is preparing to include Pneumococcal conjugate vaccines (PCV), as well. Measuring and monitoring the impact of HibCV and PCV are necessary to provide evidence for introduction and sustained admin...
International Circumpolar Surveillance (ICS) is a population-based invasive bacterial disease surveillance network. Participating Canadian regions include Yukon, Northwest Territories, Nunavut, and northern regions of Québec and Labrador (total population 132,956, 59% aboriginal). Clinical and demographic information were collected by using standardized surveillance forms. Bacterial isolates we...
