What is a protective measure soldiers can take against enteric diseases?

Using water purification tablets when needed is a vital protective measure soldiers can take against enteric diseases. These tablets are designed to eliminate harmful pathogens present in untreated or potentially contaminated water sources, which can often lead to diseases such as diarrhea, dysentery, or other gastrointestinal infections. In environments where access to safe drinking water is uncertain, utilizing these tablets ensures that water consumed is treated and safer for ingestion, significantly reducing the risk of illness.

The other options do not provide the same level of protection. Consuming meals from street vendors can expose individuals to contaminated food and unsanitary practices, increasing the risk of enteric diseases. Relying solely on bottled drinks might not be foolproof, as bottles can be opened or contaminated after purchase, and some bottled drinks may not be safe if the source is unreliable. While eating pre-packaged snacks may minimize certain risks, it does not address the necessity for safe drinking water or food preparation practices. Therefore, using water purification tablets emerges as the most comprehensive and proactive measure to safeguard against enteric diseases.
