Some diseases transmitted by unsafe water include typhoid, dysentery, cholera, measles, polio, and cryptosporidiosis.

• A. True
• B. Not always
• C. Some are not transmitted by unsafe water
• D. False

Answer: (D)

Understanding waterborne transmission means pathogens reach us through contaminated water that we drink or come into contact with. In this set, several classic waterborne infections are present—typhoid fever, dysentery, cholera, and cryptosporidiosis. Measles, on the other hand, is spread through respiratory droplets and is not transmitted via water. Because the statement lists all of these diseases as being transmitted by unsafe water, it would be incorrect. The key idea is that not every disease on the list is waterborne; the inclusion of measles makes the whole claim false.
