CAPE TOWN, South Africa - South Africa's finance minister said Wednesday the government will spend more than a quarter of a billion dollars over the next three years to double the number of people receiving AIDS medication.

Trevor Manuel, presenting his ministry's budget, said South Africa would spend an additional $274 million by 2011 to allow an extra half-million people with the AIDS virus access to antiretroviral treatment. That would bring the total to about 900,000.

Mark Heywood of the Aids Law Project welcomed Manuel's new spending plan but estimated even with the additional money, about 500,000 people in need of treatment in 2011 still would not receive it.

South Africa has 5.4 million people with the AIDS virus, the most in the world. Every day, nearly 1,000 people die of AIDS and another 1,000 are infected. The social and economic costs to the country are immeasurable.

Critics blame President Thabo Mbeki and his health minister, Manto Tshabalala-Msimang, for the scale of the crisis.

After much delay, Tshabalala-Msimang earlier this month published guidelines for preventing mother-to-child HIV transmission by using a combination of two drugs -- nevirapine and AZT -- in accordance with long-standing World Health Organization recommendations.

But in a sign of the health's ministry's ambiguous attitude toward use of medication, a doctor in the hardest-hit province KwaZulu-Natal was temporarily suspended earlier this month for giving the treatment to pregnant women in his care without awaiting official approval.

The case caused an uproar with hundreds of health professionals signing a petition demanding the doctor, Colin Pfaff, be reinstated. Pfaff said Wednesday hospital authorities told him the charges had been dropped.

"In many ways the work has only just begun," wrote Pfaff who works in an area where nearly 40 per cent of pregnant women carry the virus.

"I really hope that with dual therapy now approved...many more babies lives may be saved."
