Epidemiology and Transmission of Infectious Mononucleosis More than 90 percent of adults worldwide show serologic evidence of Epstein Barr virus infection. Most common time to develop clinical infectious mononucleosis: Freshman year in college. Incubation period for infectious mononucleosis: four to eight weeks.

Social epidemiology is defined as the study of the distribution of health outcomes and their social determinants ( 1 ). It builds on the classic epidemiologic triangle of host, agent, and environment to focus explicitly on the role of social determinants in infectious disease transmission and progression. The Epidemiologic Triangle. The epidemiologic triangle can be used to study the issues surrounding this disease. To begin with, the agent that causes the disease is a bacterium known as Mycobacterium tuberculosis. The bacterium is capable of surviving in moist air. The bacterium can be transmitted from one person to another through coughing or sneezing.

Dengue is widespread throughout the tropics, with risk factors influenced by local spatial variations of rainfall, temperature, relative humidity, degree of urbanization and quality of vector control services in urban areas. Before 1970, only nine countries had experienced severe dengue epidemics.

When the inflammation is caused by infection with the hepatitis A virus (HAV), the disease is called hepatitis A. Hepatitis A ranges in severity from a mild disease lasting several weeks to a severe disease lasting several months. Se hela listan på news-medical.net Jhung MA, Swerdlow D, Olsen SJ, et al.

Among the simplest of these is the epidemiologic triad or triangle, the traditional model for infectious disease. The triad consists of an external agent, a susceptible host, and an environment that brings the host and agent together.

This concept arose more than 60 years ago when George McNew, a plant pathologist at the Boyce Thompson Institute for Plant Research, diagrammed the fact that an epidemic arises from the interaction of three factors – a susceptible host, a virulent pathogen and a hospitable environment. This model of investigation is called the epidemiological triangle because the epidemiologist must analyze the following three elements: agent, host, and environment (Figure 5-1). The disease triangle Disease outbreaks depend on the “disease triangle,” Scholthof said. This concept arose more than 60 years ago when George McNew, a plant pathologist at the Boyce Thompson Institute for Plant Research, diagrammed the fact that an epidemic arises from the interaction of three factors – a susceptible host, a virulent pathogen and a hospitable environment. This model of investigation is called the epidemiological triangle because the epidemiologist must analyze the following three elements: agent, host, and environment . The development of disease is dependent on the extent of the host’s exposure to an agent, the strength or virulence of the agent, and the host’s genetic or immunological susceptibility.
