CHARLESTON, S.C. (WCIV) -- Three adults from Charleston have been recommended for post-exposure treatment after officials with the S.C. Department of Health and Environmental Control said they may have been exposed to rabies by a bat. Officials said the bat tested positive for the disease."Bats are a known carrier of rabies," said Sue Ferguson of DHEC's Bureau of Environmental Health Services. "Bats have very small, sharp teeth that might feel like a mosquito bite, so people may not realized they have been bitten."DHEC recommends that anyone who is exposed to rabies from a possible bite from a bat, safely capture the bat and then contact DHEC.There were 137 confirmed cases of animal rabies in South Carolina in 2012. There have been 95 confirmed cases statewide this year, officials said.
