Good Afternoon. I am pleased to be able to present to ‘you some HIV/STD data trends for Texas.

Here is what I am going to discuss today.

3. USA: Reported AIDS and HIV Cases
As of the end of 2007, 1,051,875 AIDS cases have been reported in the United States
Of these cases 7% were reported in Texas
As of the end of 2007, 328,103 HIV cases have been reported in the United States*
Of these cases 8% were reported in Texas
*Includes 47 states, District of Columbia and 5 U.S. .territories with name-based reporting as of December 2007
As of December 2007 the three jurisdictions without named reporting for HIV were Hawaii, Vermont and Maryland
As of April 2008, all 50 states, the District of Columbia, and 5 dependent areas—American Samoa, Guam, the Northern Mariana Islands, Puerto Rico, and the U.S. Virgin Islands—use the same confidential name-based reporting system to collect HIV and AIDS data.
Texas started named base reporting of HIV in 1999 and has had reporting on AIDS since 1983.

4. Cumulative Reported AIDS Cases: Top 5 States, 2007
Texas has the 4th highest cumulative numbers of AIDS cases behind New York California and Florida at about 73,000.
Centers for Disease Control and Prevention. HIV/AIDS Surveillance Report, Vol. 18

5. Texas: The Big Picture
Since 1980, >107,000 Texans have been diagnosed with HIV/AIDS
>41,000 Texans with HIV/AIDS have died
As of year end 2008, 62,772 Texans were living with HIV/AIDS
? Whe 62, 805 on dot map for end of 2007

6. New AIDS Cases, Deaths, and Persons Living with AIDS: Texas, 1980-2008
This graph shows only AIDS cases (not HIV) since it provides historical data back to the early 80s and as I mentioned previously we only started HIV reporting in 1999.
The Red line shows Persons Living With HIV has been increasing steadily since 1984.
Blue line shows NEW AIDS cases-there has been a steady increase in new AIDS cases until 1993 then a small decline to 1996 then a huge drop in the number of new cases in 1996 and Since 1998 then there has been a steady number of new cases hovering around 2700 to 2800 cases per year.
The Green line shows deaths among AIDS cases which show steady increases until 1995, then steep declines in deaths in 1996 and 1997 and has been fairly stable since 1998 with deaths among AIDS cases per year.
Why do you think there was such a sharp decline in new cases and deaths around 1996 and 1997? the first protease inhibitors were introduced and in 1996 was when HAART or Highly Active Antiretroviral Therapy (triple drug therapy) was started. Hit Early Hit HARD. HAART significantly impacted the life span of people with AIDS and also postponed those person with HIV infection from progressing to AIDS.
Deaths among AIDS Cases

7. Persons Living with HIV/AIDS: Texas, 1987 N=1,204
These dot maps are provided to show the geographic distribution of HIV/AIDS cases in Texas. Each dot represents one case of HIV or AIDS. N=1,204.
In 1987 the AIDS cases were concentrated in the large metropolitan areas and each of I-35.

8. Persons Living with HIV/AIDS: Texas, 1997 N=16,184
In 1997 the numbers of persons living with AIDS has increased to
16,184 and has spread more into the rural areas and the valley.

9. Persons Living with HIV/AIDS: Texas, 2007 N=62,805
In 2007, There is no area of the state that does not have a large number of persons living with HIV/AIDS and as we said previous over 62,000 persons living with HIV in the State of Texas.

10. 2008 HIV/AIDS In 2008… 4,293 Texans were newly-diagnosed with HIV
33% of Texans who first learned they had HIV in 2008 were diagnosed with AIDS within 1 year
2,758 Texans living with HIV progressed to AIDS
1,280 Texans with HIV/AIDS died
If 33 % of Texas diagnosed with AIDS within 1 years of their HIV diagnosis, that means that people are not getting tested and identified early in the course of the disease-this is late diagnosis. Therefore don’t get benefit of treatment sooner.
4293 includes persons new diagnosed with HIV or AIDS.
The 2, 758 is a subset of the 4,293, some may have had HIV in previously years and only progressed to AIDS in 2008.

11. Newly-diagnosed HIV Cases: Texas, 1999-2008
This chart shows number of new diagnoses of HIV in blue and new AIDS diagnoses in red from
New Diagnoses have been fairly steady since 2003 with about 3200 new HIV diagnoses and about 1000 new AIDS diagnoses per year. So about 1/3 of the new cases are AIDS cases.

12. Newly-diagnosed HIV Case Rates by Race: Texas, 1999-2008
This graph show newly diagnoses HIV cases rates by year of diagnosis and race/ethnicity
The blue line is African Americans and show a decrease in case rates since 1999 with a leveling out in recent years.
However, African Americans have the highest overall rates HIV case rates. The case rate for AAs was almost 5 times greater than the rate in Hispanics who have the next highest rates.
Hispanics have the second highest rates which have been very steady in in last 7 years.
Whites are the green line and have smaller case rates that have been very steady.
The lowest cases rates are in the other group which includes Asians, and Native Americans

This chart compares proportions of new HIV/AIDS cases by race/ethnicity to the proportion of that group in the population of Texas.
African Americans have the biggest disparity with 43% of HIV/AIDS cases being AA while only 11% of the population of Texas is African American.
Hispanics represent 36% of the population but 26% of HIV/AIDS cases

19. Perinatally Exposed and Infected Children: Texas, 1999-2008
Exposures-# of HIV positive women giving birth been steady since around 2000 at about 350 births among HIV positive women per year. There has been a huge drop in mother to child transmission from 1999 to This is one of the great public health success stories. Due to implementation of 076 trial which give antiretroviral treatment to mothers during the third trimester, at delivery and to the baby in the neonatal period. The numbers of perinatallly transmitted cases has increased sinc 2005 but these are such small numbers that it is difficult to determine if a significant increase.
