Maintaining personal hygiene is crucial in preventing the spread of infectious diseases. The measures for personal hygiene involve practices that help in minimizing the risk of contracting infections:

  1. Keeping the body clean: Regularly bathing or washing hands helps in removing dirt, sweat, and germs from the skin's surface, reducing the chances of pathogens entering the body.

  2. Consuming clean drinking water: Drinking clean, purified water reduces the risk of waterborne infections caused by bacteria, viruses, or parasites present in contaminated water sources.

  3. Consuming clean food: Eating properly cooked or washed food items, including fruits and vegetables, helps in preventing the ingestion of pathogens that might be present on the food surface.

  4. Avoiding contaminated food and water: Steer clear of consuming food or water from unsanitary sources or that might be contaminated, as it poses a high risk of transmitting various infectious agents.

Practicing these personal hygiene measures significantly lowers the chances of contracting infectious diseases caused by pathogens present in unclean environments or contaminated food and water.
