The number of parasite (protozoans), bacteria, and viruses that cause disease in humans seam to be on a continuous list, and the list of diseases that are inconclusive or without treatments are quite long as well. Sometimes, I wonder where we come in contact with them, but you know, that could be difficult to find.
Thanks for sharing.
They sure exist and they are very much around. They are microscopic hence, why they can't be seen with just the human eyes. Better way to prevent infection is by wearing protective Boots while in stagnant dirty waters.
Thanks for the read 💖
