Risk Factors for Household Transmission of in Dhaka, Bangladesh (CHoBI7 Trial).

AbstractHousehold contacts of cholera patients are at a 100 times higher risk of a infection than the general population. To examine risk factors for infections and investigate intervention strategies among this population, we followed household contacts of cholera patients for the 1-week high-risk period after the index patient obtained care. This study was nested within a randomized controlled trial of the Cholera-Hospital-Based-Intervention-for-7-days (CHoBI7), a handwashing with soap and water treatment intervention in Dhaka, Bangladesh.
