Rat-to-human transmission of cowpox infection

We isolated Cowpox virus (CPXV) from the ulcerative eyelid lesions of a 14-year-old girl, who had cared for a clinically ill wild rat that later died. CPXV isolated from the rat (Rattus norvegicus) showed complete homology with the girl's virus. Our case is the first proven rat-to-human transmission of cowpox.
