1. Good Afternoon Biology Students Tuesday May 8, 2012
You will need a few pieces of paper for today’s HIV lab
*We will begin with an easel group anticipatory activity
-You will need to record your group’s ANSWERS onto your own paper!

2. HIV Easel Group Anticipatory Questions Answer & Record on your paper
What are 4 ways that the HIV virus can be transmitted?
What family of viruses does HIV belong to?
Once a person is infected with HIV, how many years does it usually take for the virus to progress to AIDS?
Are there are treatment options for individuals with HIV? If so which ones?
Where does the HIV currently exist?

3. HIV Transmission Lab Each student is responsible for turning in their own lab!
**The worksheets you receive ARE CLASS SETS!!! DO NOT write on them!!! **On the top of your paper please write down which sections you are responsible for copying: 1. The Problem; 2. The Hypothesis; 3. Table #1; 4. Table #2

4. HIV Transmission Lab Take a few moments to read over the lab
*After you have written down the problem, write down your hypothesis (Predict how many individuals out of 12 people will eventually become infected if only one person had the infection to begin with)
**Copy down Table #1
**Copy down Table #2
ANSWER analysis questions 1-5

6. HIV Transmission Lab Reminders
*Pay attention to who you’re mixing fluids with **Do not put your pipette INTO anyone else’s test tube **Exchange 3-4 drops of solution and stir your solution using only your pipette! **You MUST be vigilant recorders, otherwise you will not be able to trace where the infection originated from

Once a person is infected with HIV, how many years does it usually take for the virus to progress to AIDS?
Are there are treatment options for individuals with HIV? If so which ones?
Where (geographically) does the HIV currently exist?

10. HIV A Human Pandemic (Worldwide outbreak of disease)

11. What is HIV? How is it Transmitted?
Human immunodeficiency virus (HIV) is a retrovirus that can lead to acquired immune deficiency syndrome (AIDS) leading to failure of the immune system
The 4 major routes of transmission: 1. unprotected sexual intercourse (semen, vaginal fluid); 2. contaminated needles (blood); 3. breast milk; 4. transmission from an infected mother to her baby at birth.
How is it Transmitted?

12. How Does HIV operate?
HIV primarily infects vital cells in the immune system such as helper T cells (specifically CD4+ T cells), macrophages and dendritic cells.
Helper T cells are a sub-type of White Blood Cells

13. Life Expectancy (LE)
About 9 out of every 10 persons with HIV will progress to AIDS after years.
Treatment with anti-retrovirals increases LE
After the diagnosis of AIDS is made average survival time with antiretroviral therapy (as of 2005) is estimated to be more than 5 years
W/O treatment death normally occurs within a year

14. There is currently no vaccine or cure for HIV or AIDS
**There is currently no vaccine or cure for HIV or AIDS. The only known method of prevention is avoiding exposure to the virus.
Antiretroviral treatment, known as post-exposure prophylaxis, is believed to reduce the risk of infection if begun directly after exposure.
**Current treatment for HIV infection consists of highly active antiretroviral therapy, or HAART (combination of 3 or 4 drugs)
Treatment

15. Why Should We be Concerned?
As of 2011, 34 million individuals are living with HIV
HIV has claimed more than 25 million lives over the past three decades
HIV does not discriminate against age, race, gender, sexual orientation or class
According to current estimates, HIV is set to infect 90 million people in Africa, resulting in a minimum estimate of 18 million orphans. (WHO)

17. WHO – World Health Organization
