# dysentery if stool bloody, fvr or wbc in stool- invasive inflamm enteropathy
# has abrupt onset, metastatic lesions, reactive arthopathies, or campylobacter assoc guillain barre- maybe flouroquinolone resis esp in SE Asia
# amoebic dysentery insidious and can get amoebic liver abscess
# if do not find infc cause of dysentery, eval pt for IBD or CA
# prolonged diarrhea and malabsorption- giardia or tropical sprue- does not respond to removal of gluten from diet- tx with tetra and folate
# also consider postinfectious disaccharidase deficiency or irritable bowel dz
# if diarrhea starts >1 mo after travel- not caused by travel

==Treatment==
# regular travelers diarrhea with fluids, antimotility agents, abx- fluoro or macrolide
# invasive enteropathy- bloody/ fvr- same but no antimotility agents
# if bloody stool but no fvr, consider enterhemorrhagic E coli- do not give abx since will get hemolytic uremic syndrome in kids
#examine stool if diarrhea invasive, persistent, unresponsive to standard tx or immune compromised
# if persistent diarrhea, give empiric flouro or macrolide or consid metronidazole for giardia- most common parasite
