What causes hookworm infectionsLife Cycle of A Hookworm | CDC – Department of Parasitic DiseasesWhat are the symptoms of hookworms in humans Itching and a localized rash are often the first signs of infection. Colic, or cramping and excessive crying in infants. These parasites live on the human anus, so they take very less time to spread ahead anything that comes in direct contact with an infected person also becomes covered with pinworm eggs.Hookworm Infections. These parasites can spread easily and are one of the most common causes behind increasing cases of parasite infections in North America.Larval growth is most proliferative in favorable soil that is sandy and moist, with an optimal temperature of 20-30☌ under these conditions, the larvae hatch in 1 or 2 days to become rhabditiform larvae, also known as L1. These larvae are developmentally arrested and nonfeeding if they are unable to infect a new host, they die when their metabolic reserves are exhausted, usually in about 6 weeks. After deposition onto soil and under appropriate conditions, each egg develops into an infective larva.Hookworm disease is a parasitic disease caused by the entry of larvae (immature form) of the hookworm, most commonly, Necator americanus, into a human host. One type can also be spread through contaminated food. If these end up in the environment, they can hatch into larvae (immature worms), which can then penetrate the skin. Hookworm eggs are deposited in the stools of infected people.Cutaneous larva migrans is endemic in the southeastern states and Puerto Rico the canine hookworm A caninum has reportedly caused eosinophilic enteritis in Australia and the United States. Hookworm infection and disease are now most likely to be found in immigrants, refugees, and adoptees from tropical countries. In 3-5 weeks, the adults become sexually mature, and the female worms begin to produce eggs that appear in the feces of the host.Worldwide, hookworms infect an estimated 472 million people. The larvae migrate through the dermis, entering the bloodstream and moving to the lungs within 10 days once in the lungs, they break into alveoli, causing a mild and usually asymptomatic alveolitis with eosinophilia. L3 live in the top 2.5 cm of soil and move vertically toward moisture and oxygen. These L3 go through developmental arrest and can survive in damp soil for as long as 2 years however, they quickly become desiccated if exposed to direct sunlight, drying, or salt water.
Studies from China and Brazil indicate a consistently increasing prevalence, from 15% at age 10 years to 60% at age 70 years and older egg counts in stool also increase in a similar pattern. In endemic areas, the highest prevalences are reported among school-aged children and adolescents, possibly because of age-related changes in exposure and the acquisition of immunity. In 2010, it was estimated that 117 million individuals in sub-Saharan Africa were infected with hookworms, as well as 64 million in East Asia, 140 million in South Asia, 77 million in Southeast Asia, 30 million in Latin America and the Caribbean, 10 million in Oceania, and 4.6 million in the Middle East and North Africa. Infection is most prevalent in tropical and subtropical zones, roughly between the latitudes of 45°N and 30°S in some communities, prevalence may be as high as 90%. Stool examination. The diagnosis is confirmed with direct microscopic analysis of fecal samples to verify the presence of hookworm eggs the specimen is fixed in formalin and prepared as a wet mount.Most cases of classic hookworm disease can be managed on an outpatient basis with anthelmintic and iron therapy, complemented by an appropriate diet. Blood studies. Anemia is confirmed by CBC and peripheral blood smear results that demonstrate signs typical of iron-deficiency anemia microscopy reveals hypochromic, microcytic red blood cells (RBCs) eosinophilia is surprisingly persistent and may be due to attachment of the adult worms to the intestinal mucosa. Cutaneous larva migrans. Cutaneous larva migrans manifests as pathognomonic, raised serpiginous tracts (creeping eruptions) with surrounding erythema that may last as long as 1 month if untreated lesions are most commonly seen on lower extremities but may be limited to the trunk or upper extremities, depending on the site at which the infective larvae entered the body.Diagnosis of hookworm infection is made through the following: Patients may exhibit pallor, chlorosis (greenish-yellow skin discoloration), hypothermia, spooning nails, tachycardia, or signs of high-output cardiac failure. Symptoms of anemia. Signs of iron-deficiency anemia are often insensitive. Deficient knowledge related to the disease process and treatment.The major nursing care planning goals for patients with hookworm are: Impaired skin integrity related to persistent scratching of the affected area. Ineffective tissue perfusion related to blood loss. Acute pain related to mucosal irritation. Nvidia driver 7zip error dataReduce or diminish pain. Provide rest periods to promote relief, sleep, and relaxation acknowledge reports of pain immediately get rid of additional sources of discomfort, and determine the appropriate pain relief method. The child and caregivers will acquire enough knowledge about the disease process and its treatment.Nursing interventions for a child with hookworm include the following: The child will have reduced itching and scratching. The child and caregivers have acquired enough knowledge about the disease process and its treatment. The child has reduced itching and scratching. The child’s perfusion is returned to normal. Enforce knowledge about the disease and its treatment. Determine priority of learning needs within the overall care plan render physical comfort for the patient grant a calm and peaceful environment without interruption include the patient in creating the teaching plan help the patient in integrating information into daily life and provide clear, thorough, and understandable explanations and demonstrations. Protect skin integrity. Monitor site of impaired tissue integrity at least once daily for color changes, redness, swelling, warmth, pain, or other signs of infection provide skin care as needed keep a sterile dressing technique during wound care clip the patient’s nails as necessary and teach patient and significant others about proper handwashing, wound cleansing, dressing changes, and application of topical medications.
