In this 2016 photograph, captured in the Quartier Morin commune in Haiti, a group of local laboratory technicians were learning how to take blood samples, and to make slides, for the very first time. They were part of a team, working on a study aimed at the elimination of lymphatic filariasis in Haiti. Each laboratorian was from the commune, where the study was being conducted, but none of them had ever performed a technique like this before. First, they watched a video on a laptop, made and produced at the Centers for Disease Control and Prevention (CDC) headquarters in Atlanta, Georgia, where CDC lab techs filmed the techniques used to draw blood, and make slides. Afterwards, these students paired up in teams of two, and practiced the technique on each other. At the end of the day, each person taught what they learned, to someone else. This was a true, international, transatlantic, “see one, do one, teach one”, collaborative lab workshop.
