Global health linkage



25 May 2010 10:30

  • Dengue and malaria are both vector-borne diseases spread by mosquitoes, but are vastly different in nature and even spread by different types of mosquitoes. Dengue causes some 250,000–500,000 severe cases of dengue fever every year, a nasty illness with no licensed vaccine or drug treatmentNew research has brought scientists one step closer to a much-needed vaccine.
  • Snakebites may seem a somewhat trivial health concern, but a global snakebite analysis points out that some 2.5 million people suffer from venomous bites each year and more than 125,000 people die as a result of venomous snakes. Especially in sub-Saharan Africa, South Asia and Southeast Asia, there is a lack of knowledge of effective antivenoms. The WHO launched an online snakebite database this month to support local health practitioners to administer the correct treatment in time.
  • Even more obscure are diseases like hookworm infection, river blindness and elephantiasis, clearly not common in the developed world. Many of the world's poor still suffer these 'neglected tropical diseases' – sometimes closer to home than expected. A new comprehensive global health initiative by the US President takes aim at eliminating some of these neglected tropical diseases.
  • The Economist takes a look at a recent Nature article on the relationship between climate change and malaria. The conclusion is interesting: 'claims that a warming climate has led to more widespread disease and death due to malaria are largely at odds with the evidence'.
