Y1 - 2011 N1 - T2 - Rudolph's Pediatrics, 22e AB - Hookworm infection remains a major health burden in developing countries.1 As many as 740 million people in the world are infected with Ancylostoma duodenale, Necator americanus, or both.2 Infections with A duodenale occur in focal regions of Africa, Asia, and South America, whereas N americanus is the predominant hookworm worldwide, with the greatest number of infections in North and South America, equatorial Africa, much of Southeast Asia, and some Pacific islands. It is important to recognize that there is significant overlap in the geographic pattern of infection and that mixed infections occur frequently. Although common in southern states in the early part of the 20th century, today there is little evidence of hookworm transmission in the United States. Other species that occasionally cause intestinal disease in humans include Ancylostoma ceylanicum, found in India and Southeast Asia,3 and the dog hookworm Ancylostoma caninum, which has been associated with eosinophilic enteritis in Australia.4 Zoonotic infection with Ancylostoma braziliense causes cutaneous larva migrans.5 SN - PB - The McGraw-Hill Companies CY - New York, NY Y2 - 2024/03/28 UR - accesspediatrics.mhmedical.com/content.aspx?aid=7031067 ER -
