Ancylostoma infectious disease, commonly called hookworm infection, happens when tiny parasitic worms reach the small intestine and drink blood from the gut wall. The worms start life as eggs passed in human stool. In warm, moist soil the eggs hatch into larvae. The infective larvae usually enter through bare skin, travel through the blood to the lungs, are coughed up and swallowed, and then grow into adult worms in the small intestine. The main human species are Ancylostoma duodenale and Necator americanus; in parts of Asia, a dog-and-cat hookworm, Ancylostoma ceylanicum, can also establish infection in people. Heavy infections may cause iron-deficiency anemia and low protein levels because the worms feed on blood and make the gut leak small amounts of blood and protein. Many people have no symptoms, but others can develop skin rash at the entry site, cough during lung migration, and later tiredness, abdominal pain, and pallor from anemia. CDC+2CDC+2
Ancylostoma infectious disease (also called ancylostomiasis, hookworm disease, and sometimes “ground-itch” at the skin stage or cutaneous larva migrans when it only affects the skin) is an infection by hookworms—mainly Ancylostoma duodenale and Necator americanus in the human gut, and dog/cat hookworms (like A. braziliense or A. caninum) in the skin. Eggs from an infected person’s stool hatch in warm, moist soil; the larvae mature, then penetrate skin (often bare feet), travel via blood to the lungs, are coughed up, swallowed, and finally attach to the small intestine where they feed on blood, causing iron-deficiency anemia and protein loss. Zoonotic species can cause winding, itchy skin tracks without entering the gut. CDC+2Medscape+2
Other names
People and articles may use several names:
Hookworm infection / Hookworm disease
Ancylostomiasis (emphasizes Ancylostoma species)
Necatoriasis (emphasizes Necator americanus)
Soil-transmitted helminth (STH) infection (group term that includes hookworm, Ascaris, and Trichuris) CDC
Types
Intestinal human hookworms
Ancylostoma duodenale (A. duodenale): common in many Old-World regions; in addition to skin penetration, it can infect by mouth (ingestion of larvae) and may rarely transmit via breast milk. CDC
Necator americanus: the most common globally; infection is mainly through skin penetration. NCBI
Ancylostoma ceylanicum: zoonotic hookworm of dogs and cats that also infects humans in parts of Southeast Asia and the Pacific. CDC
Zoonotic, extra-intestinal hookworms
A. braziliense and A. caninum typically cause cutaneous larva migrans (“creeping eruption”) when larvae penetrate human skin but cannot mature; A. caninum may cause eosinophilic enteritis without typical egg shedding. CDC+2CDC+2
Eggs leave an infected person in stool. In moist, warm, shaded soil, eggs hatch and larvae mature into a stage that can actively penetrate skin—often the feet of people walking barefoot. After entering, larvae reach the lungs, are swallowed, and mature in the intestine, where they attach and feed on blood. A. duodenale can also be acquired by swallowing larvae in contaminated food/water; N. americanus generally cannot. There is no direct person-to-person spread, because eggs need time in soil to become infectious. CDC+1
Causes
Each point explains the “cause” as a concrete exposure that increases the chance of hookworm entering the body.
Walking barefoot on contaminated soil: the main route; larvae penetrate skin easily on bare feet. World Health Organization
Open defecation or poor sanitation: eggs in human feces contaminate soil, creating a local source of infection. World Health Organization
Warm, humid climate: larvae survive weeks in moist, shaded soil, so tropical/subtropical regions see more transmission. CDC
Living or working on soil floors: earthen floors hold moisture and fecal contamination, increasing skin contact with larvae. World Health Organization
Agricultural work: farmers often work barefoot or with minimal protection in irrigated fields. World Health Organization
Children playing on the ground: frequent soil contact, and developing hygiene habits, raise exposure. CDC
Refugee/temporary settlements: crowding, limited sanitation, and shared ground space increase contamination risk. World Health Organization
Using “night soil” (untreated human feces) as fertilizer: directly introduces eggs into fields. World Health Organization
Contact with infected dogs/cats in certain regions: A. ceylanicum can establish intestinal infection in humans, especially in parts of Asia. CDC
Flooding or heavy rains: spread larvae within the soil, sustaining transmission in endemic seasons. World Health Organization
Poor access to clean water and soap: weak hygiene after defecation or farming increases contamination of surroundings. NCBI
Travel to endemic areas: short stays with barefoot exposure can be enough for infection. NCBI
Occupational mining/construction in moist soil: prolonged skin-soil contact in enclosed, damp settings. World Health Organization
No footwear in school-aged children: school-based deworming programs target this high-risk group. CDC
Earthen play areas around homes: ongoing re-exposure sustains egg-to-soil-to-skin cycles. World Health Organization
A. duodenale ingestion: swallowing larvae in contaminated produce/water can infect people (oral route). CDC
Possible transmammary transmission (A. duodenale): rarely, dormant larvae may reactivate and transmit during breastfeeding. CDC
Bare-hand gardening: skin of hands can also be a penetration site if the soil is wet and contaminated. World Health Organization
Low socioeconomic conditions: persistent poverty correlates with sanitation gaps and higher infection. NCBI
Community-level contamination: when many people are infected, daily soil contamination becomes continuous. World Health Organization
Symptoms
No symptoms at all: many people feel fine, especially with light infections. The disease can be silent. CDC
“Ground itch” at entry site: an itchy, raised skin rash where larvae entered—often between toes or on feet. NCBI
Cough or wheeze during lung migration: larvae passing through the lungs can cause a short-lived cough or chest tightness (sometimes “Loeffler’s syndrome”). NCBI
Sore throat or nausea after oral infection: swallowing larvae can irritate the throat and stomach briefly (“Wakana syndrome”). NCBI
Stomach pain: adult worms attach to the intestinal wall and can cause crampy discomfort. CDC
Loss of appetite: gut irritation and anemia reduce appetite. CDC
Diarrhea or loose stools: mild inflammation can speed gut movement. World Health Organization
Tiredness and weakness: low red blood cells from blood loss cause fatigue and reduced stamina. CDC
Pale skin or conjunctiva: anemia makes the inside of eyelids and skin look pale. CDC
Dizziness or light-headedness: reduced oxygen delivery from anemia can cause faint feelings. CDC
Fast heartbeat: the heart beats faster to keep up with low blood levels. CDC
Swelling of feet or generalized puffiness: protein loss can lower blood protein (albumin) and cause edema. CDC
Blood in stool (often invisible/occult): ongoing oozing from worm bite sites leads to positive stool blood tests. CDC
Children’s poor growth or learning problems: chronic iron and protein loss may slow growth and mental development. CDC
Rare visible worms on endoscopy: sometimes doctors see actively feeding hookworms in the duodenum during upper endoscopy done for unexplained anemia or bleeding. PMC+1
Diagnostic tests
Below are 20 tests clinicians use. Not all are needed in every person; doctors choose based on symptoms and setting.
A) Physical exam
General exam with vital signs: checks fever, heart rate, and blood pressure. Fast heartbeat or low blood pressure may reflect anemia, dehydration, or heavy blood/protein loss. (Supports the suspicion; not specific.) CDC
Pallor check (conjunctiva, palms, tongue): pale inner eyelids and skin suggest iron-deficiency anemia from chronic intestinal blood loss. CDC
Skin inspection for “ground itch”: looks for itchy, red skin at entry sites on feet or hands; early clue of exposure. NCBI
Abdominal examination: mild tenderness or bloating can be present; severe findings are unusual. (Helps rule out other causes.) NCBI
Nutritional status and growth measures: in children, height/weight/MUAC and signs like ankle swelling identify effects of chronic protein and iron loss. CDC
B) Manual/bedside tests
Fecal occult blood test (guaiac or FIT): detects unseen blood in stool, common in heavier hookworm burdens. A positive test supports blood loss from the gut. CDC
Orthostatic (postural) vitals: blood pressure and pulse changes from lying to standing can reveal volume depletion or anemia impact. (Supportive, not specific.) CDC
Capillary refill time: delayed refill may reflect poor perfusion in significant anemia. (Simple bedside screen.) CDC
WHO Hemoglobin Color Scale (HCS) or similar point-of-care Hb tools: quick manual estimation of anemia severity in low-resource settings, prompting full lab testing. (Programmatic utility.) World Health Organization
C) Laboratory & pathological tests
Stool microscopy—ova & parasite (O&P): the mainstay. A fresh stool sample is concentrated (e.g., formalin-ethyl acetate) and examined; typical thin-shelled hookworm eggs confirm diagnosis. Eggs of Ancylostoma and Necator look the same. CDC
Kato-Katz thick smear (quantifies eggs): widely used for program surveys and to estimate worm burden and treatment impact. Reading must be timely for hookworm eggs. PMC+1
Harada–Mori filter paper culture: a simple culture that lets eggs hatch so larvae can be identified, helping distinguish hookworm species from other nematodes in some labs. CABI Digital Library
FLOTAC or Mini-FLOTAC: flotation concentration methods used for egg detection/quantification, including in control programs. CDC
CBC with differential: looks for eosinophilia (often present) and measures hemoglobin to grade anemia. NCBI
Iron studies (ferritin, transferrin saturation, serum iron, TIBC): confirm iron-deficiency pattern from chronic blood loss. (Interpreted with inflammation markers when needed.) CDC
Serum albumin/total protein: low levels suggest protein loss from the gut with heavy infections. CDC
Molecular tests (PCR/LAMP) on stool: specialized assays that can detect hookworm DNA and differentiate species; used in research or reference labs. CDC
D) Electrodiagnostic test
Electrocardiogram (ECG): not for detecting worms, but useful when anemia is significant—to assess tachycardia or strain from high-output states while you search for the cause (like hookworm). (Supportive assessment.) CDC
E) Imaging & endoscopic tests
Upper endoscopy (esophagogastroduodenoscopy): in patients with unexplained iron-deficiency anemia or visible bleeding, doctors sometimes see live hookworms attached to the duodenal/jejunal mucosa, which confirms the diagnosis on the spot. PMC+1
Capsule endoscopy: a swallowed camera pill can visualize small-bowel hookworms when standard tests are negative, revealing the source of chronic bleeding/anemia. It’s not first-line but can be diagnostic in selected cases. CGH Journal+1

Dietary molecular supplements
Important: Supplements do not kill hookworms; they support recovery from iron-deficiency and nutrition gaps while anthelmintics clear worms.
Oral iron (ferrous sulfate/fumarate/gluconate) — Dose: provides ~60–120 mg elemental iron daily; consider every-other-day for tolerance. Function: rebuilds hemoglobin/iron stores. Mechanism: supplies iron for RBCs; absorption better empty stomach or with vitamin C; avoid tea/coffee nearby. PubMed+1
Vitamin C — Dose: dietary (e.g., citrus/guava) or supplement (commonly 100–500 mg with iron). Function: boosts non-heme iron absorption. Mechanism: reduces ferric→ferrous iron and forms absorbable complexes. PubMed+1
Folate (folic acid) — Dose: 0.4–1 mg/day if low intake. Function: supports RBC production with iron repletion. Mechanism: cofactor for DNA synthesis in erythropoiesis. Medscape
Vitamin B12 — Dose: typical 250–500 µg/day if diet low in animal foods. Function: supports hematopoiesis (especially if mixed deficiencies). Mechanism: cofactor in RBC maturation. Office of Dietary Supplements
Protein supplementation — Dose: food-based increases (legumes, dairy, eggs if culturally acceptable). Function: helps correct protein loss from chronic intestinal bleeding. Mechanism: supplies amino acids for plasma proteins/repair. CDC
Vitamin A — Dose: diet-first approach (leafy greens, orange vegetables). Function: supports immune function and iron metabolism. Mechanism: involved in hematopoiesis and mucosal immunity. Office of Dietary Supplements
Zinc — Dose: per RDA unless deficiency suspected. Function: general immune support, wound healing (for CLM scratch lesions). Mechanism: cofactor for immune enzymes. Office of Dietary Supplements
Probiotics/fermented foods — Dose: food-based (yogurt) or products as labeled. Function: GI comfort and general gut health while treating infection. Mechanism: microbiome support; evidence for hookworm-specific benefit is limited. Office of Dietary Supplements
Calcium spacing — Practice: avoid calcium supplements with iron dose. Function: prevents absorption interference. Mechanism: cation competition with iron transporters. Office of Dietary Supplements
Avoid tea/coffee with iron — Practice: leave several hours around iron. Function: maximize iron uptake. Mechanism: polyphenols/tannins inhibit non-heme iron absorption. Office of Dietary Supplements
Immunity-booster / regenerative / stem-cell drugs
Reality check (transparent): There are no approved “regenerative” or stem-cell drugs for hookworm. Research focuses on vaccines and better anthelmintics. Below are research/adjunct concepts, not standard treatments:
Human hookworm vaccine candidates (Na-GST-1, Na-APR-1) — In early trials/programs via Sabin Vaccine Institute to prevent N. americanus infection; not yet licensed. Office of Dietary Supplements+1
Combination anthelmintics (e.g., tribendimidine ± ivermectin/oxantel) — Investigational to improve cure rates; availability limited. Oxford Academic
Nutritional rehabilitation programs — Strengthen host immunity via diet; programmatic rather than “drugs.” CDC
WASH scale-ups — Indirectly bolster community health defenses; not a medicine but immunity support via lower exposure. BioMed Central
Peri-pregnancy iron/folate programs — Reduce anemia burden in endemic regions, improving outcomes. PMC
Deworming + education platforms — Public-health “immune resilience” by lowering worm loads community-wide. World Health Organization
Procedures/surgeries
Blood transfusion (procedure) — For severe, symptomatic anemia with hemodynamic compromise. Why: Stabilize oxygen delivery while deworming/iron work. Medscape
IV iron infusion — Not surgery, but a procedure when oral iron fails or is not absorbed. Why: Rapid iron repletion. PubMed
Dermatoscopy — Noninvasive visualization of CLM tracks. Why: Aid diagnosis in uncertain cases. PMC
Cryotherapy of small CLM lesions (selected cases) — Why: Historically used for tiny, localized tracks if medicines are unavailable; medicines are preferred today. PMC
Endoscopic evaluation (very rare) — Why: Unusual presentations (e.g., eosinophilic enteritis) or unclear GI bleeding. Medscape
Prevention
Always wear shoes outdoors in endemic areas.
Use clean latrines; never open-defecate.
Wash hands with soap after toilet/soil and before food.
Keep children off bare, damp soil; use mats.
Cover sandboxes; avoid lying directly on beach sand.
Wash produce well; avoid soil on vegetables.
Don’t use raw feces as fertilizer. 8) Join school/community deworming when offered.
Eat iron-rich foods and vitamin-C-rich foods.
Keep pets’ feces away from play areas (CLM). CDC+3World Health Organization+3BioMed Central+3
When to see a doctor (red flags)
Seek care urgently for: severe tiredness, shortness of breath, chest pain, very pale skin, black or bloody stools, fainting, fever with abdominal pain, rapidly spreading or infected skin lesions, pregnancy with anemia symptoms, or if a child has poor growth/learning problems in an endemic area. These may signal heavy infection or severe anemia needing prompt treatment (anthelmintics + iron, sometimes transfusion). CDC+1
What to eat & what to avoid (10 simple diet pointers)
Do eat: heme-iron foods (meat/fish/poultry) when acceptable.
Do eat: plant iron (beans, lentils, greens) with vitamin-C foods (citrus, guava, tomatoes, peppers).
Space out tea/coffee around iron-rich meals/supplements.
Use iron-fortified staples if available.
Include adequate protein (eggs, dairy, legumes).
Cook produce well and wash before eating.
Avoid taking calcium supplements with iron.
If iron pills upset the stomach, try every-other-day dosing.
Hydrate and eat small frequent meals if you have GI symptoms.
Follow your clinician’s plan for iron + vitamin C.
FAQs
1) How do people catch hookworm?
By skin contact with soil or sand contaminated with human (or dog/cat, for CLM) feces containing hookworm larvae—often when walking barefoot.
2) Can it spread person-to-person directly?
Not by casual contact; eggs must reach warm, moist soil to hatch before larvae can infect skin.
3) Why does it cause anemia?
Adult worms attach to your intestine and feed on blood, causing ongoing iron loss.
4) What is “ground-itch” or CLM?
An itchy, winding skin rash from animal hookworm larvae migrating in the skin surface.
5) How is hookworm diagnosed?
Mainly by stool microscopy for eggs; programs use methods like Kato–Katz; CLM is usually diagnosed clinically.
6) What is the best treatment?
Albendazole 400 mg once (intestinal) is first-line in most guides; ivermectin or albendazole (multi-day) for CLM. Clinicians adjust for age/pregnancy.
7) Do I also need iron?
Often yes—if you have iron-deficiency anemia; diet + oral iron (sometimes IV) are used.
8) Is treatment safe in pregnancy?
WHO supports deworming after the first trimester in endemic areas under medical supervision.
9) How fast do symptoms improve?
Itch can improve within days after CLM therapy; anemia recovery takes weeks to months with iron.
10) Can I get it again?
Yes—reinfection is common without shoes, sanitation, and hygiene improvements.
11) Do pets matter?
Dog/cat hookworms cause CLM on beaches/playgrounds—keep areas clean and manage pet feces.
12) Are vaccines available?
No licensed human vaccine yet; early-phase candidates (Na-GST-1, Na-APR-1) are being studied.
13) What if albendazole/mebendazole aren’t available?
Pyrantel pamoate or levamisole may be used in some settings; ask a clinician.
14) Why do programs give deworming to healthy kids?
Preventive chemotherapy lowers community worm loads and protects child growth/learning.
15) What can I do today to lower my risk?
Wear shoes, use/maintain latrines, wash hands, wash produce, and keep pets’ feces out of play areas.
