How toilets can prevent spread of disease?</h3>
- Toilets save lives! Deathly infections proliferate quickly in an absence of restrooms. Every day, over 750 kids under five pass away from diarrhea brought on by contaminated water, subpar sanitation, and bad hygiene.
- Girls who attend schools without restrooms may fall behind in their studies. Many students are compelled to skip school while they are on their period because there are inadequate sanitary facilities.
- Toilets are an excellent purchase. According to data by the WHO, every dollar spent on cleanliness has a return of $5.50 USD.
- However, 892 million individuals practice open defecation, which involves going outside and defecating in bushes, on the side of the road, or in garbage piles.
