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.
