Caption: In cholera-endemic areas such as Bangladesh, human beings are part of the cholera bacteria's ecosystem. Yet there is a simple and inexpensive tool available to thwart its progress. A sari cloth such as this, available even in the poorest household, can be folded eight to ten times. This creates a 20-micron mesh filter, as determined by electron microscopy. Straining water through several layers of sari cloth may be enough to prevent ingestion of infectious levels of cholera bacteria.
