Employing technology that reads the entire DNA code, researchers have pinpointed the source of a cholera outbreak in Haiti that killed more than 6,000 people and sickened 300,000. Using whole genome sequencing, which spells out the billions of chemical bases in DNA, the team of researchers provided the strongest evidence yet that peacekeepers from Nepal, where cholera is widespread, brought the disease to Haiti.
