MENINGEAL BRAIN WORM
Meningeal brain worm is a disease that primarily affects mule deer and, to a lesser extent, elk with fatal
results. It is a parasitic nematode that uses white-tailed deer as a host, but does not cause death. MBW
has been a contributing factor in the decline and westward recession of mule deer in parts of Nebraska.
Mule deer with MBW typically are observed standing out in the open and moderately unaware of their
surroundings.
EPIZOOTIC HEMORRHAGIC DISEASE SUMMARY
In 2021, EHD was more prevalent than in recent years affecting most of the state. The greatest losses were
in the northeastern part of the state. In 2022, the prevalence of EHD had decreased and very few reports
were made throughout the state. For more on EHD in Nebraska, visit OutdoorNebraska.gov.
