Browse categories and answer follow-up questions to refine your symptom profile.
Immediate stabilization
High risk parasitic syndrome stabilization
Airway risk
If GCS < 13, airway preparation and critical care activation
If ongoing seizure, benzodiazepine protocol and antiseizure loading
Breathing risk
If hypoxemia, oxygen escalation with continuous SpO2 monitoring
If ARDS pattern, lung protective ventilation strategy
Circulation risk
If shock, sepsis pathway with early vasopressor if fluid nonresponsive
If severe anemia with hemodynamic compromise, transfusion protocol
Rapid severity screen
Travel or residence in malaria endemic area with fever, presume malaria until excluded
Immunosuppression with eosinophilia concern, presume Strongyloides risk before steroids
Time-critical diagnostics and consultation triggers
Time-critical parasitic threats
Malaria suspicion
STAT thick and thin smear within 24 hours of presentation
If initial smear negative with high suspicion, repeat every 12 to 24 hours for 3 sets
CNS parasite concern
New seizure, focal deficit, altered mental status, urgent neuroimaging pathway
If raised ICP concern, avoid lumbar puncture until imaging
Hydatid disease concern
Large liver or lung cyst symptoms, avoid cyst aspiration without specialist plan
Severe diarrhea with dehydration
Rapid volume and electrolyte correction with stool pathogen testing plan
Consult triggers
If suspected malaria, infectious diseases and critical care early
If suspected neurocysticercosis, neurology and infectious diseases early
If suspected helminth hyperinfection, infectious diseases early
Key concepts
Key parasitic infection concepts
Protozoa
Malaria with hemolysis, microvascular sequestration, multiorgan dysfunction risk
Amoebiasis with colitis and liver abscess risk
Giardia with malabsorption and prolonged watery diarrhea
Helminths
Strongyloides autoinfection with hyperinfection risk in immunosuppression
Schistosomiasis with freshwater exposure risk and chronic organ fibrosis
Taenia solium with neurocysticercosis seizure risk
Eosinophilia pattern
Helminth infections common cause
Acute malaria typically without eosinophilia
