January 19, 2013 After a decades-long campaign, Guinea worm remains in only four countries, and eradication is in sight. But health workers say that recent violence in Mali is hindering efforts to stamp out the last few cases there.
January 17, 2013 In many parts of the world, like Europe, the plague is thought to have been eliminated. French scientists find evidence that the stubborn bacteria can trigger new outbreaks even after decades of apparent dormancy.
January 16, 2013 Canadian scientists have developed a synthetic stool that successfully treated two patients with a severe form of diarrhea. The researchers call the concoction RePOOPulate, and they produce it using a machine that recreates conditions in the colon.
January 12, 2013 On the third anniversary of Haiti's devastating earthquake, the country is laying plans to rid itself of the cholera epidemic that followed in its wake.

Officials hope a new generation of professional midwives will help reduce the pressures on Mexican hospitals overwhelmed by births that, in the past, would have taken place at home.
December 29, 2012 Researchers argue that ecology has a pretty big say in whether disease rates increase or die down. They used a new field that blends economics and ecology called "macroecology" to figure out how biodiversity loss affected disease burden.
December 19, 2012 Scientists recently sparked controversy when they made dangerous new forms of bird flu. The National Institutes of Health is about to put in place a new system for reviewing this kind of work in the future.
December 19, 2012 Myanmar and other parts of Southeast Asia are awash with shoddy and phony malaria drugs. Some fakes are almost indistinguishable from authentic drugs. The counterfeits can be deadly for patients, but they also threaten to undermine major weapons against the disease.
December 18, 2012 Global deaths from malaria have dropped sharply in the past decade, thanks in part to powerful drugs called artemisinins.
