Key Factors Contributing To The Emergence And Re-emergence Of Infectious Diseases Include:?

What are the factors contributing to 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 factors contribute to the emergence of an infectious disease quizlet?

What are the six factors involved in the emergence of these diseases? world population, urbanization, deforestation, climate changes, natural disasters, and technological advances.

How do humans contribute to the emergence of new infectious 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 factors contribute to the emergence of a new zoonosis?

Many elements can contribute to the emergence of a new zoonotic disease: microbial/virologic determinants, such as mutation, natural selection, and evolutionary progression; individual host determinants, such as acquired immunity and physiologic factors; host population determinants, such as host behavioral

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.

What are three factors that influence the spread of emerging 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.

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?

Newly emerging: Not previously recognized in humans or is just being recognized. What diseases can these animals be reservoirs for infectious diseases.

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.

How does disease spread through a population?

Some infections are spread when an infected person talks, coughs or sneezes small droplets containing infectious agents into the air. Due to their size, these droplets in the air travel only a short distance (around a metre) from the infected person before falling.

What are the three major factors of the epidemiologic triangle?

The epidemiologic triangle is made up of three parts: agent, host and environment.

  • Agent. The agent is the microorganism that actually causes the disease in question.
  • Host. The agent infects the host, which is the organism that carries the disease.
  • Environment.
  • HIV.

How do viruses jump from animals to humans?

In direct zoonosis the disease is directly transmitted from other animals to humans through media such as air (influenza) or through bites and saliva (rabies). In contrast, transmission can also occur via an intermediate species (referred to as a vector), which carry the disease pathogen without getting infected.

Why zoonoses are significant contributors to the emergence of new infectious diseases?

Many emerging diseases arise when infectious agents in animals are passed to humans (referred to as zoonoses). A factor that is especially important in the re-emergence of diseases is antimicrobial resistance – the acquired resistance of pathogens to antimicrobial medications such as antibiotics.

What are the most common zoonotic diseases?

Common zoonotic illnesses include:

  1. Rabies. Rabies is a disease that affects the nervous system of mammals.
  2. Lyme disease and Rocky Mountain spotted fever. Lyme disease is transmitted through tick bites.
  3. Dengue, malaria, and chikungunya.
  4. Salmonella infection.
  5. E.
  6. Psittacosis.
  7. Other types.
