Reporting of Positive COVID-19 Cases – Changes Effective Monday, April 18th

Effective April 18, 2022, the existing Electronic COVID-19 Case Reporting System (ECD-1) will be disabled. This system will be replaced by the Missouri Disease Reporting Online Portal (MODROP). MODROP can be accessed directly from or by using the existing ECD-1 link at and selecting the MODROP button.

NOTE: The recommended browser for use of MODROP is Google Chrome. Other browsers may cause issues with MODROP.

Facilities will need to register for a MODROP account the first time they use the new portal. MODROP allows reporting of only COVID-19 cases. Reports of other reportable conditions may be faxed to 573-751-6417.

Facilities performing their own COVID-19 testing (antigen testing) must report positive results through one of the following portals:

  • In bulk via HL7 or CSV file using the DHSS- Electronic Lab Reporting process
  • National Healthcare Safety Network (NHSN) or the Association of Public Health Laboratories (APHL) Informatics Messaging Services (AIMS) Platform.

Facilities using an external laboratory (PCR testing) must enter positive case information into MODROP.

We are excited for this change and elimination of duplicate reporting of positive cases! If you have any questions or encounter any issues utilizing MODROP or for questions about HL7 or CSV reporting, please reach out to the EpiTrax Help Desk via e-mail at The EpiTrax Help Desk e-mail account is monitored from 8AM-5PM CST Monday-Friday.

Please see the FAQ and thank you for your efforts to provide complete and accurate COVID-19 data to public health.
