The overall objective of the NIAID-funded study is to create a biorepository of specimens and associated clinical and outcome data for use in future studies of AFM, including virologic or immunologic assessments.

The University of Alabama at Birmingham (UAB) is coordinating and implementing the study and is also opening the first clinical study site.

Brief Summary: AFM is a rare but serious neurologic disease characterized by sudden muscle weakness and paralysis. It appears to occur mostly in children, often following a mild respiratory illness. As of August 2, 2019, 574 confirmed cases of AFM had been reported in the United States since August of 2014.

Study Description: Patients with suspected AFM (onset of flaccid limb weakness within the previous 30 days) are eligible to enroll in the study. Investigators will assess participants at four-time points within the first month of enrollment and will ask participants to return for additional follow up visits at 3 months, 7 months and 1 year. Neurologic improvements will be tracked over time, and samples will be collected and stored in a biorepository for use in future research studies. Household contacts, such as siblings, will be eligible to participate in the study as a control or comparison group.

Additional clinical research sites in the U.S., Canada, the United Kingdom, and Peru are expected to open in the coming months.
