With global funding for HIV/AIDS on the decline, Zimbabwe's innovative AIDS levy - a 3 percent tax on income - has become a promising source of funding for the country, with a dramatic increase in revenue collected in the past two years. The levy was introduced in 1999 to compensate for declining donor support, but low salaries and the poor performance of industry meant not enough money had been collected - until recently. According to recently published audited financial statements for the year ending 31 December 2010, a total of US$20.5 million was collected in 2010 against $5.7 million the previous year.
