Question

Begin by creating a list of questions to guide your research and help you form a convincing argument. Your presentation should answer some of these questions: What is the definition of a pandemic? How does a pandemic differ from an endemic or epidemic? What is the life cycle of the HIV virus once it enters the body? How does the genetic code of the virus change? How does HIV affect the body? How do people become infected with HIV? How does AIDS develop from an HIV infection? What are the current infection rates of HIV across the globe? Where is HIV/AIDS most prevalent? What treatments are currently available for HIV/AIDS? Do some regions of the world have better access to treatments than others? What is the average life expectancy for someone with HIV? Does life expectancy differ around the globe? Now write four additional questions about HIV/AIDS that could help strengthen your argument in the presentation.

Answer 1

Answer:

A pandemic is an epidemic disease extended across wide regions, thereby affecting many countries and even continents, while endemic diseases affect the people from only one country or a specific region. Human Immune Deficiency (HIV) is an RNA virus whose life cycle is composed of the following stages: 1) binding to the cell host and membrane fusion, 2) subsequent reverse transcription into DNA and integration into genome host 3) proliferation (i.e., successive replication cycles) by using the cellular machinery of the host 4) new assembly and budding of the virus. The acquired immune deficiency syndrome (HIV/AIDS) occurs when the host immune system is seriously damaged by the HIV infection, this being the latest stage of infection. It is known that HIV/AIDS is more prevalent in the female population, while according to ethnic groups, it is more prevalent in African-American and Hispanic/Latino populations in the USA. The life expectancy in HIV-infected patients has notably improved in the last years and, currently, people with this disease can expect to live over 70 years or even more.
