AB Eight  species  of  Paragonimus  lung  flukes  cause  human  disease.  The  most  important  is  Paragonimus  westermani.  Paragonimus  species  are  endemic  in  East  Asia,  Oceania,  West  Africa,  and  South  America,  where  millions  of  persons  are  infected;  rare  infections  caused  by  Paragonimus  kellicotti  have  occurred  in  North  America.  Eggs  are  released  into  freshwater,  where  parasites  infect  snails,  and  then  cercariae  infect  crabs  and  crayfish.  Human  infection  follows  consumption  of  raw,  undercooked,  or  pickled  freshwater  shellfish.  Metacercariae  then  excyst,  penetrate  the  peritoneum,  and  pass  into  the  lungs,  where  they  mature  into  adult  worms  over  about  2  months  (eFigure  35–26).
