Parvovirus
Parvovirus
Parvovirus (/pɑːrˈvoʊˌvaɪrəs/; from Latin, parvus, meaning small) is a genus of the Parvoviridae family of viruses. Parvoviruses are small, non-enveloped, single-stranded DNA viruses that are known to infect a broad range of animals, including humans.
Etymology
The term "parvovirus" comes from the Latin word "parvus", which means small. This is in reference to the small size of the virus particles.
Classification
Parvoviruses are classified under the family Parvoviridae. This family is further divided into two subfamilies: Parvovirinae and Densovirinae. The Parvovirinae subfamily includes viruses that infect vertebrates, while the Densovirinae subfamily includes viruses that infect invertebrates.
Infection and Symptoms
Parvoviruses can cause a variety of diseases in animals. In humans, the most well-known parvovirus is B19 virus, which causes Fifth disease, a common childhood illness characterized by a "slapped cheek" rash. Other symptoms may include fever, fatigue, and joint pain.
In dogs, Canine parvovirus can cause severe gastrointestinal illness and is often fatal in puppies. Symptoms include vomiting, diarrhea, and loss of appetite.
Prevention and Treatment
Prevention of parvovirus infection in humans primarily involves good hygiene practices, as the virus is spread through respiratory droplets. In dogs, vaccination against canine parvovirus is highly effective and is a standard part of puppy care.
Treatment for parvovirus infection is primarily supportive, as there is no specific antiviral therapy for these viruses. This may include hydration, pain relief, and in severe cases, hospitalization.
