Identify the statement that does not provide accurate evidence as to why HIV is so lethal. a.During the course of infection, HIV increases immune activation by altering intestinal physiology to let more microbes into the blood supply. b.Immune evasion increases in many infections due to HIV virions evolving new and unrecognizable epitopes (antigens). c.In many individuals the virus population evolves to use different receptors to gain access to a greater diversity of host immune cells. d.HIV causes enhanced replication and proliferation of T cells, which allows the immune system to work better at defending against pathogens.

HIV is a disease which is cause by RNA virus. It's a specifically a disease of immune system.

Use the text as guide, answering the question, as a medical technology student, what is the importance of understanding RA 11166? Enumerate at least 4 ways how are you going to promote HIV awareness?
Which of the following is the most likely explanation for an individual who lacks CCR5 as a result of a homozygous defect in the CCR5 gene becoming infected with HIV? a. The mutated CCR5 genes reverted to the normal form, rendering macrophages susceptible to macrophagetropic HIV variants. b. The macrophage-tropic HIV variant entered host cells using CD4 alone. c. The viral nucleic acid alone was taken up by cells, as in cell transformation by bacterial DNA. d. The individual had received a transplant of HIV-infected cells expressing normal CCR5. e. The primary infection involved a lymphocyte-tropic strain of HIV that used CXCR4 as its co-receptor.
Consider that the Herd Immunity Threshold is dependent on the reproduction number for an infectious disease. The combination of herd immunity and quarantines were highly effective for eradicating smallpox. What is different about the symptoms of polio infection that makes quarantining infected individuals much more difficult?
In a recent influenza epidemic, physicians were utilizing a rapid diagnostic test to determine which patients were infected with influenza type A, type B, or not infected with influenza virus. Such a test was not available in the massive 1918 outbreak that killed millions of people around the globe. How might the availability of such a test have impacted that outbreak, and why?
Scenario: In a rural community, a primary health care nurse is conducting a door-to-door vaccination campaign to address a recent outbreak of measles. The nurse notices that many parents are hesitant to vaccinate their children due to misinformation. The nurse decides to organize an educational seminar to address these concerns. What approach should the nurse take to effectively communicate the importance of vaccination? Options: A) Use complex medical terms to explain the effectiveness of vaccines. B) Distribute printed materials without engaging in direct conversation. C) Employ a culturally sensitive communication strategy, using simple language and visual aids. D) Recommend vaccination without providing any rationale.
Which of the following best explains why vaccination of humans against rabies can be delayed until after exposure to a potential source of infection? A) Antibody responses are more rapid than those against other viruses B) T lymphocyte responses are more rapid than those against other viruses C) The virus does not infect any cells for several weeks or months D) The virus does not reach i target organ for several weeks or months
Influenza vaccines must be changed yearly because the amino acid sequence of the viral proteins change gradually over time. Based on this information, which is the most logical conclusion? The influenza virusa) is enveloped. b) is non-enveloped.c) has a DNA genome. d) has an RNA genome.e) causes a persistent infection.
Assume you are studying the infection dynamics between a species of spider and a species of ringworm that infects the spider. You sequence the genomes of each species for 30 years and find that each of these species has evolved adaptations. Specifically, the spider has evolved immune system adaptations to remove the ringworm and the ringworm has evolved counter-adaptations to evade the spider's immune system. Surprisingly, you find that the ability of the ringworm to infect the spider has not changed over 30 years. The finding that infectiousness has not changed in 30 years would be in support of which of the following? a. The Red Queen Hypothesis b. Muller's Ratchet c. The Asexual Reproduction Benefit Hypothesis d. The Genetic Load Hypothesis
Three methods have been used to try to eliminate malaria. One is to eliminate the mosquito vectors of the parasite, a second is to kill the parasites after they have entered the human body, and the third is to develop a vaccine against the parasite, allowing the human immune system to provide protection from the disease. Which do you suppose is the most promising in the long run? Why? Think about both the biology of the disease and the efficacy of carrying out each of the methods on a large scale .
Which of the following is a commonality between coxsackievirus A16 infection and a varicella zoster infection?Choose one: A. Both infections are caused by viruses in the herpes family. B. Each disease is usually mild and self-limiting in children but is more severe in adults. C. Both viruses can cause a spotted rash to appear on the palms of the hands and soles of the feet. D. There is a vaccine available for both viruses.
From a global health viewpoint howdoes HIV/AIDS fit into either the ecological/evolutionary model of disease or the political-economy model of disease?
a.) Why is HIV infection dangerous? b.) How is the HIV virus transmitted? C.) And how can infection be prevented?
