Trichinella usually grow up to ¼ inch and they live inside of
animal
Found in Mexico, northern hemisphere southern Asia,
Africa, South America, and middle East and other

Hookworm
Hookworms can be found all throughout the world, but most commonly
in areas where there is a constant moist warm climate. They reside
in Asia, Africa, and are the only human infecting hookworms to
reside in North Africa, the Middle East, and Southern Europe.
When it comes to feeding, hookworms get quite the variety of
nutrition. At each stage in their life, they gain nutrients from different
substances ranging from the soil to human intestinal mucus.
Hookworms are approximately one centimeter by 0.5 millimeter which
mean they are very small
Ascaris
Ascaris are all over the world but are mostly found in Africa and South
