Hookworm Infection: An Unseen Threat to Your Health

Intestinal helminthiasis, a group of parasitic diseases caused by worms in the intestines, affects millions worldwide. Hookworm infection, or necatoriasis or ancylostomiasis, is a common type of intestinal helminthiasis that can have serious consequences if left untreated.

Transmission

Hookworms are tiny, roundworms that live in the small intestine of humans. They are transmitted through contact with contaminated soil or feces. The eggs of hookworms are found in the soil, and when they hatch into larvae, they can penetrate the skin, often through the feet. These larvae then travel through the bloodstream and end up in the lungs. From there, they are coughed up and swallowed, eventually reaching the small intestine where they mature into adult worms.

Common Species

The two most common species of hookworms that infect humans are Ancylostoma duodenale and Necator americanus. Ancylostoma duodenale is found in tropical and subtropical regions of the world, while Necator americanus is more commonly found in warmer climates.

Symptoms

Hookworm infection can cause a range of symptoms, from mild to severe. In the early stages of infection, you may experience skin irritation and itching at the site where the larvae entered the skin. As the worms mature and begin to feed on blood in the small intestine, you may experience abdominal pain, nausea, and diarrhea.

Anemia

One of the most serious complications of hookworm infection is anemia. Hookworms attach to the lining of the small intestine and feed on blood, leading to a decrease in red blood cells. Anemia can cause fatigue, weakness, shortness of breath, and dizziness. In severe cases, anemia can be life-threatening.

Treatment

Fortunately, hookworm infection is treatable with a course of medication. The most commonly used medication is albendazole, which is given orally. Treatment is typically effective in killing the worms and resolving the symptoms of infection.

Prevention

Preventing hookworm infection is essential to protect your health. Here are some preventive measures you can take:

  • Wear shoes or sandals when walking on contaminated soil.
  • Practice good hygiene, such as washing your hands frequently and using clean water for drinking and cooking.
