The Centers for Disease Control and Prevention (CDC) has been collaborating with the International Centre for Diarrheal Disease Research (ICDDRB) over the last 40 years – most recently to strengthen the country’s capacity to detect emerging infectious diseases and to evaluate new vaccines and other interventions. A strong collaboration between CDC and the Institute of Epidemiology Disease Control and Research (IEDCR) within the Bangladesh Ministry of Health and Family Welfare has further strengthened the country’s ability to detect and respond to disease threats. Since 2002, a CDC medical epidemiologist has led the Program on Infectious Diseases and Vaccine Sciences at ICDDRB.
