New report: Washington DC (mostly blacks) has a huge AIDs infection rate.

>>Among its findings: Almost half of those who had connections to the parts of the city with the highest AIDS prevalence and poverty rates said they had overlapping sexual partners within the past 12 months, three in five said they were aware of their own HIV status, and three in 10 said they had used a condom the last time they had sex. <<

What part of "branching factor" don't you understand? (Oh, any of it, probably)

>>Black men, with an infection rate of nearly 7 percent, carry the weight of the disease, according to the report, which also underscores that the District's HIV and AIDS population is aging. Almost 1 in 10 residents between the ages of 40 and 49 has the virus. <<

Evolution in action.

That would be interesting to model computationally.

>>More than 4 percent of blacks in the city are known to have HIV, along with almost 2 percent of Latinos and 1.4 percent of whites. More than three-quarters -- 76 percent -- of the HIV infected are black, 70 percent are men and 70 percent are age 40 and older.<<
