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
