We are also engaged in investigating the transmission of cholera in Bangladesh. The goals of this work are to further understand the burden and role of mildly symptomatic cholera cases in propagating transmission through in-depth surveillance at multiple points in the healthcare system including pharmacies, in addition to household visits in the Tongi subdistrict of Dhaka, Bangladesh. By combining temporal, spatial, and molecular data from this study we also hope to gain new insights into the relative importance of direct-like and environmentally mediated transmission in the community.
Through working with multiple partners, including Médecins Sans Frontières (MSF), the World Health Organization (WHO), the United Nations High Commissioner for Refugees (UNHCR), and various Ministries of Health, we are trying to maintain a large database of cholera incidence and mortality that can accommodate surveillance data that comes in all shapes and size (for example, different case definitions, reporting intervals, and spatial scales). We are also developing methods to integrate all of this data into a common statistical framework to better understand cholera burden and transmission dynamics worldwide.
