PARAVACCINIA VIRUSES Meaning and
Definition
-
Paravaccinia viruses refer to a group of viruses that belong to the Orthopoxvirus genus. These viruses are known to infect a range of mammals including humans, cats, cattle, and rodents. They are characterized by their ability to cause localized skin infections and lesions.
Paravaccinia viruses are closely related to the cowpox virus (CPXV) and the vaccinia virus (VACV). They share similar morphological and genetic characteristics, but exhibit distinct clinical features and host preferences. Paravaccinia viruses can be transmitted through direct contact with infected animals or contaminated material.
In humans, infection with paravaccinia viruses typically leads to a self-limiting condition called "milker's nodule" or "pseudovaricella". This presents as a single lesion, usually on the hand, and is often accompanied by symptoms such as redness, swelling, and pain. While the infection usually resolves on its own within a few weeks, in rare cases it can cause more severe manifestations such as lymphadenopathy and fever.
Diagnosis of paravaccinia virus infection is primarily based on clinical symptoms, but laboratory tests, such as polymerase chain reaction (PCR), can be used to confirm the presence of the virus. Treatment options are generally supportive and aimed at relieving symptoms.
In summary, paravaccinia viruses are a group of Orthopoxviruses that can cause localized skin infections in a variety of mammals, including humans. While they typically result in mild disease, some individuals may experience more severe symptoms.

Etymology of PARAVACCINIA VIRUSES
The term "Paravaccinia viruses" is a combination of two words, "para" and "vaccinia", with the addition of "viruses" at the end.
1. "Para" is a prefix derived from the Greek word "para", meaning "beside" or "near". In scientific terminology, it is often used to describe viruses that are closely related to or resemble a specific virus. It suggests that Paravaccinia viruses are similar to, but distinct from, the vaccinia virus.
2. "Vaccinia" is taken from the Latin word "vaccīna", meaning "cow". The term was originally used in the context of cowpox, a viral infection in cows that was found to provide immunity against smallpox in humans. The vaccinia virus, part of the Poxviridae family, was used as a basis for developing smallpox vaccines.
