- How are acute, chronic, and latent infections different from one another?
Step by step
Solved in 3 steps
- How does a latent infection differ from a chronic infection?Is this a graph of an acute, chronic or latent disease?Pathogenic infections induce damage to the host by a variety of mechanisms. While many mechanisms are direct effects of the pathogen, some damaging mechanisms result from the immune response to the infection. Examples of damage caused by the host immune response are: a) Exotoxin production, endotoxin b) Cell-mediated inmunity, direct cytopathic effect c) Endotoxin, inmmunune complexes d) Direct cythopathic effect, endotoxin e) Cell-mediated inmunity, inmmunune complexes
- What are healthcare-associated infections?How is it that we are not in a state of continuous infection from the microbes we encounter every day?Normal microbiota provide protection from infection in each of the following ways EXCEPT: Question 3 options: A) they produce antibacterial chemicals. B) they compete with pathogens for nutrients. C) they make the chemical environment unsuitable for nonresident bacteria. D) they produce lysozyme.
- How do the diagnoses and treatments of infectious diseases differ globally and culturally within different regions of the world and how does economics affect a country’s ability to prevent and treat infections?Which type of infection is the MOST easily spread to the largest number of people? Question 3 options: a) gastrointestinal b) vector-borne c) respiratory d) sexually transmittedWhat does it mean to refer to a disease as a “syndrome,” as with AIDS?
