A mysterious ailment is turning some black bears friendly and unafraid of humans, among other unusual symptoms.
Scientists think the health problem, which appears to affect young bears around a years of age, is a sort of encephalitis, meaning a swelling of the brain, according to a news release from the California Department of Fish and Wildlife late last month. Considering that 2014, a handful of bears in Nevada and California have shown signs of the condition, and 4 California bears were validated to have it in the last year.

The sleeping sickness has other major results on the bears, including tremblings, head tilts and seizures. Affected bears also tend to be seriously underweight. One female bear, observed in February choosing up an apple and consuming it among humans on a patio, weighed just 21 pounds when she ought to have been around 80 pounds. Two bears displaying neurological issues in recent years, nevertheless, were able to find new houses.

Its still unclear exactly whats triggering the brain swelling. In the course of studying the phenomenon, scientists have actually recognized five previously unknown viruses in the impacted bears.
These viruses are not thought to present any danger to people, Jamie Sherman, a vet at the University of California, Davis One Health Institute informed the Sacramento Bee.
Bears struggling with sleeping sickness usually have to be euthanized. Their symptoms make them unequipped to endure in the wild, and those placed in zoos or sanctuaries can become “a substantial burden” due to the long-lasting treatment theyll require, wildlife veterinarian Brandon Munk said in the CFDW release.
2 bears showing neurological concerns in recent years, however, were able to find brand-new houses. One, now called Elinor, was brought to the Orange County Zoo.
