Question

#1 What is the HIV epidemic? (give specific details from your readings) #2 The main transmission routes of HIV are: 1. unsafe sex with an HIV-infected partner 2. sharing injection paraphernalia with an HIV-infected partner 3. vertical transmission of HIV from the HIV+ mother to the newborn (before or at birth; or later, due to breastfeeding) Research the cdc.gov website and search for statistics for these 3 transmission routes. What did you find? # 3 What is meant by the natural course of the HIV infection? #4 When did the Human Immunodeficiency Virus emerge? And how? (use your text) #5 The discovery of HIV as the cause of AlIDS was made in 1983. Since then HIV/AIDS has emerged as a worldwide epidemic which continues to spread 30 years later - with still mare than 2 million new infections each year. today What preventative measures would you take to stop the future spread of this disease?

Answer 1

Ans) 1) Epidemics in which the prevalence of HIV infection has not consistently exceeded 1% in the general population nationally or 5% in any subpopulation.

- HIV prevalence refers to the number of people living with HIV at a specific point in time and is expressed as a percentage of the population.

2) 1) unsafe sex with an HIV- infected partner

Explaination:

high-risk sexual contact

There are four main routes of HIV transmission: unprotected vaginal or anal or oral sex (oral sex carries a very small risk).

3) The lower the CD4 count in chronic infection, the higher the risk from HIV-related infections. But even when the CD4 count is very high, HIV can still cause serious problems without ART. ART quickly reduces viral load – by 90% in a few days. Viral load should then become undetectable within 1 to 3 months.

4) Analysis of a newly discovered HIV sequence from 1960 suggests that the virus entered the human population around the beginning of the twentieth century. The first AIDS cases in the U.S. were reported in 1981.
