For example, communications from public health officials shared during outbreaks can motivate people to adhere to disease prevention strategies. Invasive Group A, Streptococcus, But there are other factors that have contributed to its spread, such as unvaccinated travelers returning home from countries that have a large number of measles cases. Reaching out to all of those people may not be possible, especially in urgent situations such as outbreaks. Epidemiology examples include classical, clinical, population, sample, and data-focused types. The challenge is in determining which data is relevant for current epidemiological studies. U.S. National Library of Medicine, What Are Epidemiology Studies? 2001. Epidemiologists use phylogenetic methods to understand the development of pandemics, patterns of disease transmission, and development of antimicrobial resistance or pathogenicity: Basler, C.F., et al. Nurses with research skills and epidemiology knowledge can make an impact by planning and evaluating strategies to prevent the spread of illnesses. World Health Organization, Epidemiology. Conclusions are based on comparisons Clues to aetiology come from comparing disease rates in groups with differing levels of exposure – for example, the incidence of congenital defects before and after a rubella epidemic or the rate of mesothelioma in people with or without exposure to asbestos. Through the multidisciplinary approach known as epidemiology, public health officials can answer key questions about the origins and spread of outbreaks and diseases that affect public health. For example, initial respiratory symptoms might indicate exposure through the upper airways, as in Table 6.2. So a sample population — a smaller group of people representing the entire population — will be selected for the study. Epidemiologists perform various functions as they work to control diseases. Data epidemiology methods enable researchers to achieve three key goals: determine quickly what existing relevant data is available for analysis, identify what data is missing, and establish processes to enable the fast and efficient collection of data. This program provides the knowledge, skills and attitudes to effectively educate the ‘nurse of the future’. To stop the spread of the disease, it is important to determine the factors behind its re-emergence.
