Prevalence and distribution of Taeniasis and Cysticercosis
No full textTaenia saginata and Taenia solium are found through the whole world, especially in developing countries. These tapeworms live in the small intestines of humans. Cattle and pigs are the intermediate animal hosts. Serious signs and symptoms are found if T. solium is infecting the central nervous system. Cases with epileptic seizures and abnormal behavior are often found in endemic areas. In Mexico among 68.754 human serum samples 0,06-2,97% were found positive for cysticercosis. Apparently there was an association between high sero prevalence rates and low socio-economic conditions. In several countries in Latin America, prevalences were between 0,1-8,7%, whereas prevalences between 0,05-10,4% were detected in Asia and Africa. In Indonesia taeniasis/cysticercosis are mostly found in three provinces i.e. North Sumatra, Bali and Irian Jaya. Cases were also discovered in North Sulawesi, Southeast Sulawesi, East Nusa Tenggara and West Kalimantan. The prevalences of taeniasis/cysticercosis in Indonesia were between 1,0-42,7%. The highest prevalence rate was in Irian Jaya (Papua). Not many reports are available for cysticercosis in cattle and in pigs in the world, including Indonesia. The collection of epidemiological data such as on prevalence rates and distribution are needed for a successful control program. In addition community health education should be implemented in control programs
Evidence-based control of canine rabies: a critical review of population density reduction
Get PDFControl measures for canine rabies include vaccination and reducing population density through culling or sterilization.
Despite the evidence that culling fails to control canine rabies, efforts to reduce canine population density continue in many parts of the world.
The rationale for reducing population density is that rabies transmission is density-dependent, with disease incidence increasing directly with host density. This may be based, in part, on an incomplete interpretation of historical field data for wildlife, with important implications for disease control in dog populations. Here, we examine historical and more recent field data, in the context of host ecology and epidemic theory, to understand better the role of density in rabies transmission and the reasons why culling fails to control rabies.
We conclude that the relationship between host density, disease incidence and other factors is complex and may differ between species. This highlights the difficulties of interpreting field data and the constraints of extrapolations between species, particularly in terms of control policies.
We also propose that the complex interactions between dogs and people may render culling of free-roaming dogs ineffective irrespective of the relationship between host density and disease incidence.
We conclude that vaccination is the most effective means to control rabies in all species
