Epidemiology is the study and analysis of the distribution who, when, and where , patterns and determinants of health and disease conditions in defined populations. It is a cornerstone of public health , and shapes policy decisions and evidence-based practice by identifying risk factors for disease and targets for preventive healthcare. Epidemiologists help with study design, collection, and statistical analysis of data, amend interpretation and dissemination of results including peer review and occasional systematic review. Epidemiology has helped develop methodology used in clinical research , public health studies, and, to a lesser extent, basic research in the biological sciences. Major areas of epidemiological study include disease causation, transmission , outbreak investigation, disease surveillance , environmental epidemiology , forensic epidemiology , occupational epidemiology , screening , biomonitoring , and comparisons of treatment effects such as in clinical trials. Epidemiologists rely on other scientific disciplines like biology to better understand disease processes, statistics to make efficient use of the data and draw appropriate conclusions, social sciences to better understand proximate and distal causes, and engineering for exposure assessment.
Asthma inhalers contain prescription medications that are breathed directly into the lungs to relieve or prevent asthma symptoms. Inhalers may contain a steroid medication that reduces airway inflammation or a bronchodilator medication that opens the airways. Some asthma inhalers contain both. The medications in long-acting inhalers are used to prevent asthma symptoms on an ongoing basis and so often are described as controllers although not all controllers come as inhalers. They work by counteracting the underlying causes of asthma. There are two types of long-acting asthma inhalers: those containing long-acting bronchodilators and those containing corticosteroids sometimes simply called steroids.
