Which disease is NOT transmitted by water?

AIDS
Cholera
Giardia
Typhoid fever

The correct answer is: AIDS

AIDS is primarily transmitted through contact with infected bodily fluids such as blood, semen, vaginal fluids, and breast milk. It is not spread through contaminated water, which distinguishes it from the other options listed. Cholera, Giardia, and Typhoid fever are all diseases linked to waterborne transmission, meaning they can be contracted through consuming or coming into contact with contaminated water sources. Cholera is caused by the bacterium Vibrio cholerae, Giardia is a protozoan parasite, and Typhoid fever is caused by Salmonella typhi—each of these pathogens can be found in water that has been contaminated with fecal matter. This highlights the critical role of clean water sources in preventing waterborne diseases, while AIDS does not fit this category due to its different transmission routes.
