“HIGH RISK GROUP” MODEL ACCORDING TO “HRG” MODEL, THE EXTENT OF SPREAD OF HIV IN A POPULATION WILL DEPEND ON: FRACTION OF PEOPLE IN “HRG”s (CSWs, MIGRANT LABORERS, ETC) AND THE DEGREE OF “MIXING” BETWEEN HIGH AND LOWER RISK GROUPS.

WHERE DID MARTINA MORRIS GET THE IDEA THAT LONG TERM CONCURRENCY WAS DRIVING THE HIV EPIDEMIC IN AFRICA? UGANDAN DOCTORS……

Condoms? Since the beginning of the HIV/AIDS epidemic, a considerable amount of programmatic effort has focused on condom promotion… Reported condom use last higher-risk sex for ages 15-24 (UNAIDS, 2001 & BAIS 2001) Given that Botswana has for some time featured some of the highest rates of (self-reported) condom use in the world, why isn’t Botswana hailed alongside of Uganda as a major success story? Percent

C is for condomize 1 Shelton, et al (2004) “Ever” use of condoms among adults increased from 15 to 30 percent in men, and from 7 to 20 percent for women, from 1989 to 1995 1 Botswana may have the highest levels of reported condom use in Sub-Saharan Africa Uganda:Botswana:

“CONSISTENT” CONDOM USE PROTECTS, BUT NOT TOTALLY….(PROBABLY BECAUSE THE USE IS NOT AS CONSISTENT AS IT SHOULD BE.)

B is for be faithful Uganda coined (from agricultural tradition) the “zero- grazing” approach to prevention 1 Shelton, et al (in press) 3 BAIS (2001) 2 UNAIDS (2002) Uganda: Botswana: Uganda 1 :

Early successes: Uganda and “zero grazing”

Early successes: Thailand and “100% condoms”

The HIV rate is beginning to decline in several African countries, including Kenya, Zimbabwe and I think maybe Malawi and Zambia. But—why did it take so long? And why is the HIV rate still so high in southern Africa?
52
IMPLICATIONS FOR PREVENTION? AFRICAN PEOPLE NEED TO KNOW WHERE THEIR RISKS ARE COMING FROM—IE NOT JUST FROM “PROMISCUOUS PEOPLE.” MY HYPOTHESIS IN INVISIBLE CURE IS THAT AN UNDERSTANDING OF CONCURRENCY NETWORKS COULD HELP REDUCE THE STIGMA AND DENIAL SURROUNDING THE EPIDEMIC IN MUCH OF SOUTHERN AFRICA, AS IT DID IN UGANDA, AND THIS COULD FOSTER A MORE PRAGMATIC RESPONSE TO THE EPIDEMIC.. UGANDANS DID KNOW EARLY ON THAT HIV WAS SPREADING THROUGH CONCURRENT LONG TERM RELATIONSHIPS ALTHOUGH THEY DIDN’T USE THE WORLD “CONCURRENCY.” UGANDAN GOVERNMENT CAMPAIGNS MADE IT CLEAR THAT EVERYONE WAS AT RISK, NOT JUST SEX WORKERS AND PROMISCUOUS, ‘IMMORAL’ PEOPLE. THIS HELPED ROUSE A MORE COMPASSIONATE, OPEN REPONSE TO THE AFFLICTED, AND A GENERAL RECOGNITION THAT AIDS WAS NEITHER AN ACT OF GOD OR A PUNISHMENT FOR SIN, BUT A TERRIBLE DISEASE THAT NO ONE DESERVES. TOO MANY HIV PREVENTION PROGRAMS HAVE DIVIDED PEOPLE: HIV POS FROM HIV NEG, MORAL FROM IMMORAL, YOUNGER PEOPLE FROM ELDERS, MEN FROM WOMEN. WHAT WE NEED ARE MORE PROGRAMS THAT BRING PEOPLE TOGETHER: WOMEN’S RIGHTS PROGRAMS, MICROFINANCE PROGRAMS, ORPHAN CARE PROGRAMS, HOME BASED CARE PROGRAMS, ETC.
