Thereafter, using the bloodstream as the carrier, they migrate in the body until they enter the lungs.
#HOOKWORMS IN HUMANS SYMPTOMS SKIN#
Upon contact, these larvae attach themselves to the skin, usually on the foot, and break the skin to penetrate it. These eggs mature, hatch, and develop into infective larvae in 7-10 days. When an infected person does that, the eggs are passed along with the feces. In developing nations of the tropics and sub tropics, given the unavailability of proper sanitary disposal system, most people defecate directly on grounds. Hookworm infection is more severe in children as it might cause growth retardation. The ill effect which follows includes anemia, and loss of iron (and protein) in the gut. americanus hookworm can feed on 0.03 mL of blood per day, and a A. Hookworms are known as blood suckers as they ingest blood from the host’s intestinal walls and damage the mucosa. Infection caused by Necator americanus, on the other hand, can occur through penetration and oral transmission as well. Infection from Ancylostoma duodenale occurs solely through direct contact of the skin with soil contaminated with the parasitic larvae. Mostly, Ancylostoma duodenale and Necator americanus are the species of hookworms that cause the infection. Human hookworm infection does not cause any prominent symptoms, and that is why about 70% of people suffer from the infection without knowing about it. The Necator americanus, however, do not have teeth but rounded ventral cutting plates. The Ancylostoma duodenale hookworm species possesses 2 pointed ventral teeth on each side which it uses to suck blood from its host.
