Baldwin County Health Department officials said a sentinel chicken in the Orange Beach area has tested positive for Eastern Equine Encephalitis.
In the report released on Monday, the department said ongoing public health surveillance detected no mosquito-borne virus activity in humans in Baldwin County this year.
Eastern equine encephalitis, West Nile virus and other mosquito-borne viruses are transmitted from bird to mosquito to bird. Occasionally, when bird hosts are scarce, the same mosquitoes
will take blood from mammals, including humans and horses. People and horses can sometimes become ill from the infection.
Officials say that although there is a vaccine for horses, there is not one for humans.
