Cowpox is a viral skin infection caused by the cowpox or catpox virus. This is a member of the Orthopoxvirus family, which includes the variola virus that causes smallpox. Cowpox is similar to but much milder than the highly contagious and sometimes deadly smallpox disease. Cowpox should also not be confused with cowpock, which is an alternative name for a condition called milker’s nodules, which is caused by a parapox virus.
