Porcine Circoviruses are small, circular DNA viruses that primarily infect pigs. They belong to the family Circoviridae and are known to cause various diseases in swine, particularly Porcine Circovirus Type 2 (PCV2), which is associated with conditions like Porcine Multisystemic Wasting Syndrome (PMWS). These viruses are highly resilient and can survive in the environment for extended periods. Infection can lead to significant economic losses in the pig industry due to decreased growth rates, increased mortality, and the need for veterinary interventions. Vaccination and biosecurity measures are essential for managing their spread.
