Compare the definitions of Acute Infections and Chronic Infections

Question: Compare the definitions of Acute Infections and Chronic Infections below. Based on what you know about HIV/AIDS at this point, which description most closely matches AIDS? Explain your answer, using evidence from the book to support your position.
What is an acute infection?
1. Produces symptoms and makes a person infectious soon after infection.
2. The infected person may:                                                                                                                                                                                          transmit the disease
die from the infection
recover and develop immunity
3. the acute microorganism
STRIKES QUICKLY
infects entire group (small group)
dies out
What is a chronic infection?
Person may never show symptoms
Person continues to carry infectious agent at a low level
Does NOT mount an effective immune response
Subtopic 4: Controlling infectious disease
Question: Explain what herd immunity is and how it works. Use an example from either the book or the internet to explain your position.
Herd immunity = when all, or nearly all susceptibles are immunized, no new infection can occur. Agent can be eradicated from the population.
Subtopic 5: Modern concepts of Infectious Disease and Koch’s Postulates
From the Oxford Dictionary:
Definition: postulate
verb |ˈpäsCHəˌlāt| [ with obj. ]
1 suggest or assume the existence, fact, or truth of (something) as a basis for reasoning, discussion, or belief: his theory postulated a rotatory movement for hurricanes | [ with clause ] : he postulated that the environmentalists might have a case.
a thing suggested or assumed as true as the basis for reasoning, discussion, or belief: perhaps the postulate of Babylonian influence on Greek astronomy is incorrect.
Robert Koch was a physician/scientist in the 1800s who studied the transmission of infectious disease. He proposed 4 postulates, also known as Koch’s Postulates (p. 12-13) help control the spread of infectious disease.  He proposed that a microorganism can be considered to be a disease if it fulfills certain criteria or conditions. These are listed on p. 12 in the textbook. The book also goes on to describe how these postulates helped to prevent the spread of the plague pandemic in the late 1800s.
Question: Using what you learned from the movie “And the Band Played On”, described the ways that Koch’s postulates helped scientists to identify what was going on with this new acquired immune deficiency syndrome (AIDS), and to help it from exploding completely out of control.
Module 2 Reflection
In each module, we’ll have a final discussion to “reflect” on what we learned this week. Here you can post commentary on something that we discussed, how a concept would apply to a particular situation, etc. For Week 2, why don’t you each just tell me a new insight that you learned about infectious disease. You can make multiple posts if you’d like, or pose questions for additional discussions. be creative. Everyone should make at least one meaningful comment, and that should be at least 100 words.
