Al-Qahtani indicated that there are many diseases caused by living organisms called parasites, which is a living organism that lives on or inside another living organism (the host).

Parasite entry

And about the ways in which parasites enter the body, Al-Qahtani reported that they enter through the mouth or the skin. Parasites that enter through the mouth come through contaminating food and drink with eggs, and they can remain in the intestine or harbor in the intestinal wall and invade other organs. As for parasites that enter through the skin, they puncture the skin. Directly through the soles of the feet when a person walks barefoot, through the skin when a person swims or bathes in water containing parasites, or enters through the bites of infected insects.

Al-Qahtani stressed the importance of health awareness to prevent parasitic diseases through various media, pointing to some ways to prevent these diseases, most notably: peeling vegetables and fruits and washing them well, freezing and cooking meat well, and reducing eating fast food as much as possible.
