By Region
The pandemic is not homogeneous within regions, with some countries more afflicted than others. Even at the country level, there are wide variations in infection levels between different areas. The number of people infected with HIV continues to rise in most parts of the world, despite the implementation of prevention strategies, Sub-Saharan Africa being by far the worst-affected region, with an estimated 22.9 million at the end of 2010, 68% of the global total. South and South East Asia have an estimated 12% of the global total. The rate of new infections has fallen slightly since 2005 after a more rapid decline between 1997 and 2005. Annual AIDS deaths have been continually declining since 2005 as antiretroviral therapy has become more widely available.

Famous quotes containing the word region:
“It was a favor for which to be forever silent to be shown this vision. The earth beneath had become such a flitting thing of lights and shadows as the clouds had been before. It was not merely veiled to me, but it had passed away like the phantom of a shadow, skias onar, and this new platform was gained. As I had climbed above storm and cloud, so by successive days’ journeys I might reach the region of eternal day, beyond the tapering shadow of the earth.”
—Henry David Thoreau (1817–1862)
“For poetry was all written before time was, and whenever we are so finely organized that we can penetrate into that region where the air is music, we hear those primal warblings, and attempt to write them down, but we lose ever and anon a word, a verse, and substitute something of our own, and thus miswrite the poem.”
—Ralph Waldo Emerson (1803–1882)
