The New Jersey Department of Health continues to work with Local Health Departments and federal partners to investigate Cyclosporiaisis cases and monitor for any potential illness clusters. While there have been increases in cases reported nationally and clusters of cyclosporiasis in several states (particularly in the Midwest), to date NJ has been experiencing normal seasonal circulation without known clusters or outbreaks.   

Action Items  

  • Clinicians should consider cyclosporiasis as a clinical diagnosis?when the clinical presentation, history or travel suggests a possible infection. 
  • All cases should be reported by the next business day to the Local Health Department through ELR or manual reporting into CDRSS.  
  • Local health department (LHD) investigators should promptly interview all cyclosporiasis cases with the CDC Cyclosporiasis National Hypothesis Generating Questionnaire (CNHGQ), submit the CNHGQ to the Foodborne and Waterborne Disease Unit, and update CDRSS.
