The national Centers for Disease Control and Prevention (CDC) continues to receive information about cases of acute flaccid myelitis (AFM), a serious condition that causes weakness in the arms and/or legs. The Mississippi State Department of Health continues active surveillance for cases of interest of acute flaccid myelitis (AFM).

The specific causes of most AFM cases are still being investigated. The CDC has not determined the causes of most of these AFM cases despite extensive lab testing. All of the AFM cases have tested negative for polio virus. There are several possible causes of AFM such as viruses, environmental toxins and genetic disorders. According to the CDC, AFM may also result when the body’s immune system attacks and destroys body tissue that it mistakes for foreign material.

AFM is a rare but serious condition. We are working closely with health care providers and the CDC to get more information.

MSDH will continue to actively investigate patients of interest for AFM, send samples to the CDC for testing, and monitor disease activity. MSDH will continue to work with our health care professionals to increase awareness, provide guidance, and submit samples to the CDC to conduct lab testing to better understand the AFM cases, risk factors, and possible causes.
