Hookworms Study Guide 2026
Hookworms are parasitic worms that infect the small intestine of humans and animals.
These blood–feeding parasites are prevalent in many parts of the world, particularly in
tropical and subtropical regions with poor sanitation and limited access to clean water.
Hookworm infections can lead to various health issues, such as anemia, malnutrition, and
stunted growth, particularly in children and pregnant women.
This article aims to serve as a comprehensive nursing guide to hookworms, exploring their
life cycle, modes of transmission, common symptoms, diagnostic methods, and treatment
options.
What are Hookworms?
, Historically, hookworm infection has disproportionately affected the poorest among the
least-developed nations, largely as a consequence of inadequate access to clean water,
sanitation, and health education.

• Human hookworm disease is a common helminth infection that is predominantly
caused by the nematode parasites Necator americanus and Ancylostoma duodenale;
organisms that play a lesser role include Ancylostoma ceylonicum, Ancylostoma
braziliense, and Ancylostoma caninum.
• Hookworm infection is acquired through skin exposure to larvae in soil contaminated
by human feces.
• Soil becomes infectious about 9 days after contamination and remains so for weeks,
depending on conditions.
Pathophysiology
The life cycle of hookworms begins with the passing of hookworm eggs in human feces and
their deposition into the soil.
