Hookworms

Hookworms are intestinal parasites that reside in the small intestine and feed on the nutrients in their host's blood. They measure between 4-13mm in length and are usually contracted through contact with contaminated soil or water. Hookworms can cause severe malnutrition, anemia, and even death in humans, especially children, due to their ability to cause blood loss. As such, they are a major global health concern, causing over 600 million cases of infection worldwide, according to the World Health Organization. Appropriate treatment and prevention is necessary to reduce their spread and severity. Control measures include improving hygiene and sanitation, access to clean water, and the safe disposal of human waste. Vaccination can be used to control the spread, but is not available in many countries.
