Step by step
Solved in 5 steps
- What are the similarities and differences between airborne and direct disease transmission? Discuss the vehicles and methods for transmission prevention.What is epidemiology? there are several ways pathogens can be transmitted including direct contact, indirect contact, via respiratory droplets, vehicle, and through a vector. Describe each mode IN DETAIL and give an example of a pathogen that can be transmitted each way.Explain what is meant by systemic infection and localised infection giving examples from practice of both terms
- Describe the factors that contribute to the emergence or re-emergence of disease.Research the following communicable diseases (flu/cold, HIV, salmonella and malaria) and provide an explanation comparing: 1. Disease profile 2. The microorganism/pathogen responsible 3. Causation 4. Disease transmission 5. Treatment and any risk factors (You may wish to present your information as a table)Define the terms primary pathogen, opportunist, and virulence.
- Discuss how a pathogen causes an infection. Include definitions for primary pathogen, opportunistic pathogen, infection, disease (caused by a living organism), and various stages of pathogenesis. You can choose a specific organism to describe (like Orthomyxovirus and Influenza) or discuss a generalized infection.Explain in details epidemiology and the environmental factors that contribute to the spread of disease.Please discuss What is the use of personal protective equipment in helping to reduce the spread of infection?.
- Below are a list of virulence factors/ strategies paired with an example of an organism that utilizes them. How do each of the following strategies contribute to the virulence of the pathogen? Strategy - Causes the host to produce more receptors (Organism - Rhinovirus) Strategy - Produces gas as a product of fermentation (Organism - Clostridium perfringens) Strategy - Produces a capsule (organism - Klebsiella pneumonia) Strategy - Ability to move between adjacent cells (organism - Cytomegalovirus) Strategy - Ability to use pilus as a motility structure (organism - Pseudomonas aerogenosa)identify one type of pathogen or infectious agent. Describe ways to prevent the spread of the diseases this type of pathogen can cause and explain why these preventative measures are important.Compare subclinical infection and chronic infection.
