Porcine Circovirus Type 2 (PCV2) is a virus that primarily affects pigs, particularly young ones. It is a small, circular virus that belongs to the family Circoviridae. PCV2 is known to cause various diseases in pigs, including Porcine Circovirus Associated Disease (PCVAD), which can lead to symptoms like weight loss, respiratory issues, and skin lesions. The virus is transmitted through direct contact with infected animals or contaminated environments. Vaccination has become a common preventive measure in pig farming to reduce the impact of PCV2. Effective management practices are also essential to control the spread of the virus and protect pig health.
