The death of Aids
In a week in which the world is once again invited to consider the prospect of climatic Armageddon, it would be easy to miss the news of remarkable progress against one of the greatest killers known to mankind. UNAIDS, the United Nations agency responsible for the global battle against Aids, forecast that the epidemic will very likely be over by 2030. That does not mean that the disease will be declared extinct by then — as smallpox was in 1979 and rinderpest in 2011 — but that the incidence of transmission of HIV and death from Aids will have fallen to levels low enough to constitute a chronic public health problem rather than an epidemic. Already, worldwide deaths from the disease have fallen by a third since a peak of 2.3 million in 2005.
