Overview
Cyclospora cayentanensis must be differentiated from other diseases that cause watery diarrhea, loss of appetite and abdominal pain, such as viral gastroenteritis (adenovirus, rotavirus, norovirus), bacterial infections (bacillus cereus, clostridium perfringens, vibrio cholerae) or other protozoan infections (entamoeba histolytica, isosporiasis, cryptosporidium parvum).

| Differential Diagnosis | Additional Findings |
|---|---|
| Adenovirus | Fever, flu-like symptoms, more common in children |
| Rotavirus | Most common cause of watery diarrhea in children |
| Norovirus | Nausea, vomiting, low grade fever, food or waterborne transmission |
| Enterotoxigenic Escherichia coli (ETEC) | "Traveler's diarrhea", cholera-like diarrhea, foodborne transmission, ingestion of undercooked hamburger meat |
| Food poisoning (S. aureus, C. perfringens, B. cereus) | Nausea, vomiting, abdominal pain, toxins foodborne infection |
| Campylobacter jejuni | Fever, may be associated with bloody stools, ingestion of undercooked poultry |
| Salmonellosis | Fever, abdominal pain, may have bloody stools |
| Vibrio cholerae | Profuse watery diarrhea ("rice water"), vomiting, dehydration |
| Giardia intestinalis | foul-smelling stools, bloating, flatulence, malabsorption |
| Cryptosporidium spp | Nausea, vomiting, abdominal pain, weight loss, associated with HIV infection[1] |
