Un análisis de un día, sin equipos sofisticados, permitiría actuar antes de que la enfermedad se extienda por el barrio. Para quien vive donde el agua corriente no siempre es segura, la diferencia entre enterarse hoy o dentro de tres días puede ser la diferencia entre tomar precauciones o no.

Conventional detection methods for V. cholerae in environmental water samples, including membrane filtration and culture, typically require about three days, specialized equipment, and technical expertise. A simple and rapid method for detecting the V. cholerae O1 in water could support outbreak prevention, environmental surveillance, and studies of persistence and transmission. Here, we describe a low-cost, streamlined method for detecting toxigenic V. cholerae O1 in environmental water which can detect V. cholerae O1 within 24 hours.
