Acute Flaccid Myelitis Reporting
AFM Home AFM Data AFM Resources Investigation Job Aid for Clinicians VPD Home VPD Reporting VPD Resources
Acute flaccid myelitis (AFM) is not nationally notifiable; CDC relies on clinician recognition and health department reporting of suspected AFM cases to learn more about AFM and what causes it1. Texas is participating in enhanced AFM surveillance.
Clinicians should continue to be vigilant and send all information about patients that meet the clinical criteria (sudden onset of flaccid limb weakness) for AFM to their state or local health department. Since AFM is a relatively new condition, we need information on all patients to help us better understand the spectrum of AFM illness, all possible causes, risk factors, and outcomes for this condition. Clinicians should send information on patients who meet the clinical criteria regardless of any laboratory results or MRI findings.1
Clinicians should work with their state or local health department to complete the patient summary form provided below as soon as possible after patient identification so that they can be monitored in real time. Information should be sent to the local or state public health department regardless of any laboratory and MRI results.1
How to report and AFM procedures can be found in the Job Aid for Clinicians PDF.
CDC Requested Information and Documents:
- Patient summary form
- Medical record information
- History and physical (H & P)
- All MRI reports
- All neurology consult notes
- EMG (if done)
- Infectious disease consult notes (if available)
- Vaccination record
- Diagnostic laboratory reports
- All MRI images (brain and spine) should be uploaded to a secure CDC transfer website
- Contact DSHS or local health department for web link and CDC ID#
Per CDC request please submit all above requested information to your local health department. Requested documents can also be sent to Department of State Health Services via secure email to AFMTexas@dshs.texas.gov or faxed to 512-776-7616.
AFM Specimen Shipping and Handling
Clinicians should collect specimens from patients suspected of having AFM as early as possible in the course of illness, preferably on the day of onset of limb weakness. Prior to shipping contact local or state public health. CDC requests specimens be submitted to the DSHS laboratory not directly to the CDC.
Specimen Type | Minimum Amount | Collection | Storage | Shipping | Comments | |
Required Specimens | ||||||
Cerebrospinal fluid (CSF) | 1 mL | Spun and processed; standard cryovial tube; collect at same time or within 24 hours as whole blood | Freeze at -70°C | Ship on dry ice | ||
Respiratory - NP swab | 1ml | Store in viral transport medium | Freeze at -20°C | Ship on dry ice | Send for EV/RV testing at CDC regardless of previous test results | |
Serum | 0.4 mL | Spun and processed; Tiger/red top tube | Freeze at -70°C | Ship on dry ice | ||
Stool | =1gram | Collect in sterile container, no special medium required | Freeze at -20°C | Ship on dry ice | Two samples total, collected at least 24 hours apart, both collected as early in illness as possible and ideally within 14 days of illness onset | |
In the event of death, please send the following specimens, if possible | ||||||
Fresh-frozen tissue | Place directly on dry ice or liquid nitrogen | Freeze at -70°C | Ship on dry ice | Representative sections from various organs are requested, but particularly from brain/spinal cord (including gray and white matter), heart, lung, liver, kidney, and other organs as available. | ||
Formalin-fixed or formalin-fixed, paraffin-embedded tissue | Avoid prolonged fixation—tissues should have been fixed in formalin for 3 days, then transferred to 100% ethanol | Room temperature | Ship at room temperature with paraffin blocks in carriers to prevent breakage | See comment above regarding frozen tissue |
Please ship specimens overnight so they arrive at DSHSLab in Austin on Tuesday through Friday. Do not ship specimens on Friday or over the weekend.
*Common cause for rejection is no two patient identifiers and missingG-2V forms. Ensure each specimen has two patient identifiers such as first and last name AND date of birth. Each specimen must have a completed G-2V form.
