Evolutionary Dynamics of the Haitian Cholera Outbreak Strains

Yan and Fabini were part of a huge collaborative group, lead by Dr. Lee Katz and Dr. Cheryl Tarr of the Centers for Disease Control and Prevention (CDC), that published an article today in mBio entitled "Evolutionary dynamics of Vibrio cholerae O1 following a single-source introduction to Haiti." The article shows that the source of cholera, caused by V. cholerae, that hit Haiti in 2010 following the devastating earthquake came from a single source and was not introduced repeatedly to Haiti.

Other members of the group were researchers and public health officials from the National Microbiology Laboratory – Public Health Agency of Canada, Mount Sinai School of Medicine, Georgia Institute of Technology, Pacific Biosciences, Haiti National Public Health Laboratory, and Harvard University.

The manuscript was received, accepted (unconditionally), and published all within SIX WEEKS. The release was also picked up by science news blogs EurekAlert! and mBiosphere.
