Specific factors precipitating disease emergence can be identified in virtually all cases.
These include ecological, environmental, or demographic factors that place people at increased contact with a previously unfamiliar microbe or its natural host or promote dissemination.
What factors contribute to the emergence of an infectious disease?
Factors that have contributed to these changes are population growth, migration from rural areas to cities, international air travel, poverty, wars, and destructive ecological changes due to economic development and land use.
What factors contribute to the emergence of an infectious disease quizlet?

What are the 3 factors that cause disease?

What are the factors that influence disease transmission?
Six factors are involved in the transmission of communicable diseases: the infectious agent, the reservoir, route of exit, mode of transmission, route of entry, and the susceptible host. A reservoir is a human, another animal, or a non-living thing (such as soil), where the infectious agent normally lives.
What are three factors that influence the spread of emerging diseases?
Many factors are contributing to disease emergence, including climate change, globalization and urbanization, and most of these factors are to some extent caused by humans. Pathogens may be more or less prone to emergence in themselves, and rapidly mutating viruses are more common among the emerging pathogens.
What are the 5 major types of infectious agents?
A variety of microorganisms can cause disease. Pathogenic organisms are of five main types: viruses, bacteria, fungi, protozoa, and worms. Some common pathogens in each group are listed in the column on the right. Infectious agents can grow in various body compartments, as shown schematically in Fig.
Which two factors are largely responsible for the re emergence of infectious diseases?
Responsible factors include ecological changes, such as those due to agricultural or economic development or to anomalies in climate; human demographic changes and behavior; travel and commerce; technology and industry; microbial adaptation and change; and breakdown of public health measures.
What is an emerging infectious disease quizlet?
