The spread of the HIV virus to any society is a major health challenge.

"The first case of AIDS was recorded in Brazil in 1982, and whilst many countries have struggled to curb the spread of HIV and to care for those with AIDS, Brazil’s response has been seen as a success story. Working alongside civil society groups, the Brazilian government has made aggressive efforts to minimize the impact of the AIDS epidemic. By the end of 2007, 730,000 Brazilians were living with HIV1 – just over half the number that estimates in the previous decade had predicted. The AIDS mortality rate has fallen and the number of people who avoided hospital due to to effective treatment saved over US$2 billion in medical costs between 1996 and 2004.

Since 2000, the number of Brazilians living with HIV has stabilized around 600,000. However, the overall AIDS incidence rate has increased, possibly due to the delayed effect of HIV infections in previous years. The rise in AIDS incidence has not led to an increase in the AIDS mortality rate, which significantly declined since the introduction of treatment in 1996 from 9.6 annual deaths per 100,000 people, to 5.1 in 2006.20 It should be noted, however, that the North and North-East regions of Brazil have seen increases in AIDS mortality over the course of the decade.

HIV Aids can bring many economic problems to Brazil. Brazil faces an epidemic spread of the HIV virus that will divert resources away from building the economy and into maintain the health of it's citizens."
