South Africa has a long-standing malaria programme aimed at controlling both the vector and the parasite of the disease. It has been extremely successful as evidenced by the low mortality rate, the low incidence rate (Strebel et al. 1986, Sharp and le Sueur 1996, Ngxongo 1994) and the large areas of the country freed from epidemics in relation to the situation prior to control (Sharp et al. 198...
There continues to be profound differences in TB incidences as well as in TB treatment and care across Europe in recent years. High TB incidences are observed in Eastern Europe and especially among injecting drug users (IDUs), and there are large overlaps with a HIV epidemic, which is also far from being under control in this region. Further, mortality rates among HIV-positive patients with TB ...
A delayed SIR epidemic model with a generalized incidence rate is studied. The time delay represents the incubation period. The threshold parameter, R0(τ) is obtained which determines whether the disease is extinct or not. Throughout the paper, we mainly use the technique of Lyapunov functional to establish the global stability of both the disease-free and endemic equilibrium.
BACKGROUND AND PURPOSE There is a scarcity of information on the epidemiology and natural course of moyamoya disease. The aim of this study was to investigate the nationwide epidemiological features of moyamoya disease in Korea, including incidence, prevalence, and survival. METHODS We used the data from nationwide, population-based Health Insurance Review and Assessment Service claims databa...
There are two common methods for comparing disease incidence rates (such as cancer) in two populations (such as pulp and paper workers vs non-pulp and paper workers). In cohort studies, the two groups are followed over time and the incidence rates are directly compared. These types of studies can be inefficient for low incidence diseases when very large sample sizes are needed. Case-control met...
BACKGROUND The report of the Ministerial Review of Trauma and Emergency Services in Victoria, Australia, recommended that paramedics be permitted to divert to the closest hospital in incidences of life threatening situations prior to and during transport. An audit of patients that suddenly deteriorated in paramedic care was recommended by the Ministerial Review. The objective of the study was t...
The aim of this study was to survey multiple birth data and to analyze the recent trends of multiple births and its consequences on perinatal problems in Korea from 1991 to 2008. Data were obtained from the Korean Statistical Information Service. The total number of multiple births showed increasing trends. The multiple birth rate was maintained within less than 10.0 for the decade from 1981 to...
OBJECTIVE To describe the epidemiology of illness at the Rio 2016 Summer Paralympic Games. METHODS A total of 3657 athletes from 78 countries, representing 83.5% of all athletes at the Games, were monitored on the web-based injury and illness surveillance system (WEB-IISS) over 51 198 athlete days during the Rio 2016 Summer Paralympic Games. Illness data were obtained daily from teams with th...
During 2000 to 2009, data on people undergoing HIV testing and on those newly diagnosed with HIV were collected in a network of 20 Spanish clinics specialising in sexually transmitted infections and/or HIV testing and counselling. The number of tests performed, overall and disaggregated by different variables, was obtained. HIV prevalence among first-time testers and HIV incidence among repeat ...
