What Are Hookworms?

Hookworm is an intestinal parasite that tends to be found in areas with high population density and inadequate sanitation – and thus rare in the United States. There are two types of hookworm which can cause infection in humans:

• Ancylostoma duodenale (A. duodenale) – these are largely found in southern Europe, northern Africa, northern Asia, and some parts of South America.
• Necator americanus – these parasites were once found in the southeastern United States during the early 20th century¹.

While hookworms were historically present in the southern United States, modern sanitation practices have virtually eliminated them domestically. Today, infections typically occur only in travelers returning from endemic regions.

If untreated, they can live for several years¹ inside their host and cause a range of symptoms – some simply uncomfortable, some much more serious if left untreated.

How Do You Contract Hookworm?

You can contract them by coming into contact with soil that's contaminated with them. In many of the countries where hookworm is prevalent, it's common to walk around barefoot, which means many people contract them through their feet. Many children also play or work in dirt, which also allows the hookworm to enter the body through their hands. The method of contraction means it can't be transmitted from person to person, and can only be acquired through contact with the larvae in soil.

What Are the Symptoms of a Hookworm Infection?

Hookworm infections are most commonly asymptomatic, but when symptoms do occur, they can include a rash, abdominal pain, diarrhea, and in severe cases, an iron deficiency².

Treating Hookworm Infections

COMBANTRIN® Chocolate Squares 24 Pack is effective against multiple types of worms including hookworm. The active ingredient in the product – Pyrantel Embonate – paralyzes the worms within the body and causes them to be eliminated in bowel movements. However, COMBANTRIN® will not eliminate any eggs or immature worms in the body, nor will it prevent any future infections.

Remember to follow up the initial dose with another around two to four weeks later if symptoms persist – this will eliminate any eggs which may have hatched and matured into adults during that timeframe. Hookworm infections are extremely rare in the United States, but if you suspect your child may have contracted one, it's advisable to seek medical attention for additional treatment and guidance.
