Squirrel Pox Spreads Across US Backyards, Leaving 3 Rehab Cases in Michigan

Summary
Lesion-covered squirrels have been reported in backyards across several US states, with wildlife officials warning squirrel pox can turn fatal when tumors block eating, sight or movement.
Ohio wildlife researcher Laurie Brown said the virus spreads mainly through mosquitoes, though flies and biting midges can also transmit it between squirrels.
Three squirrels have reached one Michigan rehabber: Phlox recovered and was released in late June, Bugsy is still improving, and a 2025 case named Maxine also survived after about a month of care.
The virus is not known to infect humans, pets or other animals besides squirrels, and officials recommend removing standing water and outdoor food sources to reduce spread.
