Will Climate Change Banish or Breed Disease?

Climate change’s definitive effects on infection rates of parasitic worms in humans are still hypothetical. What’s clear: There will be effects with potential to both help and hinder current control measures of infections in Africa and Asia.

For example, temperatures and shifting weather patterns may wipe out African snail populations that host parasitic worms that cause schistosomiasis. But these same conditions also force mosquitoes carrying lymphatic filariasis to expand their breeding range, potentially infecting more people.

Adding to the list of unknowables are the effects of rapid infrastructure development in some regions on local ecosystems.
