Epizootiology, epizoology, or veterinary epidemiology is the study of disease patterns within animal populations. [1]
Epidemiology is the study and analysis of the distribution, patterns and determinants of health and disease conditions in a defined population.
The science of epidemiology has matured significantly from the times of Hippocrates, Semmelweis and John Snow. The techniques for gathering and analyzing epidemiological data vary depending on the type of disease being monitored but each study will have overarching similarities.
In pathology, pathogenesis is the process by which a disease or disorder develops. It can include factors which contribute not only to the onset of the disease or disorder, but also to its progression and maintenance. The word comes from Ancient Greek πάθος (pathos) 'suffering, disease' and γένεσις (genesis) 'creation'.
In epidemiological research, recall bias is a systematic error caused by differences in the accuracy or completeness of the recollections retrieved ("recalled") by study participants regarding events or experiences from the past. It is sometimes also referred to as response bias, responder bias or reporting bias.
Dermatophytosis, also known as tinea and ringworm, is a fungal infection of the skin, that may affect skin, hair, and nails. Typically it results in a red, itchy, scaly, circular rash. Hair loss may occur in the area affected. Symptoms begin four to fourteen days after exposure. The types of dermatophytosis are typically named for area of the body that they affect. Multiple areas can be affected at a given time.
The Epidemic Intelligence Service (EIS) is a program of the United States' Centers for Disease Control and Prevention (CDC). The modern EIS is a two-year, hands-on post-doctoral training program in epidemiology, with a focus on field work.
Computational epidemiology is a multidisciplinary field that uses techniques from computer science, mathematics, geographic information science and public health to better understand issues central to epidemiology such as the spread of diseases or the effectiveness of a public health intervention. Computational epidemiology traces its origins to mathematical epidemiology, but began to experience significant growth with the rise of big data and the democratization of high-performance computing through cloud computing.
Landscape epidemiology draws some of its roots from the field of landscape ecology. Just as the discipline of landscape ecology is concerned with analyzing both patterns and processes in ecosystems across time and space, landscape epidemiology can be used to analyze both risk patterns and environmental risk factors. This field emerges from the theory that most vectors, hosts, and pathogens are commonly tied to the landscape as environmental determinants control their distribution and abundance. In 1966, Evgeniy Pavlovsky introduced the concept of natural nidality or focality, defined by the idea that microscale disease foci are determined by the entire ecosystem. With the recent availability of new computing technologies such as geographic information systems, remote sensing, statistical methods including spatial statistics and theories of landscape ecology, the concept of landscape epidemiology has been applied analytically to a variety of disease systems, including malaria, hantavirus, Lyme disease and Chagas' disease.
The UCLA Jonathan and Karin Fielding School of Public Health is the graduate school of public health at UCLA, and is located within the Center for Health Sciences building on UCLA's campus in the Westwood neighborhood of Los Angeles, California. The UCLA Fielding School of Public Health has 690 students representing 25 countries, more than 11,000 alumni and 247 faculty, 70 of whom are full-time.
Genetic epidemiology is the study of the role of genetic factors in determining health and disease in families and in populations, and the interplay of such genetic factors with environmental factors. Genetic epidemiology seeks to derive a statistical and quantitative analysis of how genetics work in large groups.
Neuroepidemiology is a science of incidence, prevalence, risk factors, natural history and prognosis of neurological disorders, as well as of experimental neuroepidemiology, which is research based on clinical trials of effectiveness or efficacy of various interventions in neurological disorders.
Pharmacoepidemiology is the study of the uses and effects of drugs in well-defined populations.
Anal dysplasia is a pre-cancerous condition which occurs when the lining of the anal canal undergoes abnormal changes. It can be classified as low grade squamous intraepithelial lesions (LSIL) and high-grade squamous intraepithelial lesions (HSIL). Most cases are not associated with symptoms, but people may notice lumps in and around the anus.
Clinical epidemiology is a subfield of epidemiology specifically focused on issues relevant to clinical medicine. The term was first introduced by virologist John R. Paul in his presidential address to the American Society for Clinical Investigation in 1938. It is sometimes referred to as "the basic science of clinical medicine".
An infection rate or incident rate is the probability or risk of an infection in a population. It is used to measure the frequency of occurrence of new instances of infection within a population during a specific time period.
Filicollis anatis is an endoparasite in the Polymorphidae family of thorny-headed worms. Adults have been found to occur in waterbirds such as ducks, where they cause a condition known as filicollosis. Larval stages occur in invertebrate hosts such as crayfish.
Reduvius sonoraensis is a species of assassin bug in the family Reduviidae. It is found in Central America and North America. It can have two types that are discernably different by the fifth instar: those with short wing pads and those with long wing pads.
Salmonid herpesvirus 2 (SalHV-2) is a species of virus in the genus Salmonivirus, family Alloherpesviridae, and order Herpesvirales.
Kirsten Tackmann is a German politician. Born in Schmalkalden, Thuringia, she represents The Left. Kirsten Tackmann has served as a member of the Bundestag from the state of Brandenburg since 2005.
Janina Oyrzanowska-Poplewska was a Polish academic and veterinarian. A professor at the Warsaw University of Life Sciences, she specialized in epizootiology but her main area of research concerned viral diseases of canines, which led to the development of the first vaccine for canine distemper in Poland.
