Abstract:
Porcine Circovirus Type 2 (PCV-2) is a viral pathogen that affects pigs worldwide, leading to significant economic losses in the swine industry. PCV-2 is associated with various clinical manifestations, including post-weaning multisystemic wasting syndrome (PMWS), porcine dermatitis and nephropathy syndrome (PDNS), respiratory disease, and reproductive disorders. These conditions can result in decreased growth rates, increased mortality rates, impaired reproductive performance, and reduced meat quality. Consequently, PCV-2 infections have a direct negative impact on pig health and welfare. The economic implications of PCV-2 are substantial. The disease imposes significant costs on pig producers, including expenses associated with increased mortality, reduced growth rates, vaccination programs, diagnostic tests, and treatment regimens. Additionally, PCV-2-related conditions can result in decreased market value of affected animals and trade restrictions imposed by importing countries, further impacting the profitability of the swine industry. Various control measures have been implemented to mitigate PCV-2 infections, including vaccination programs, improved biosecurity measures, and management practices aimed at minimizing the transmission of the virus. Although these interventions have shown some success in reducing the prevalence and severity of PCV-2-associated diseases, challenges remain in their widespread adoption and effectiveness. Understanding the economic implications of PCV-2 is essential for policymakers, veterinarians, and swine producers to make informed decisions regarding disease prevention, control strategies, and resource allocation. This review article highlights the economic burden of PCV-2 and the importance of continued research and investment in disease management strategies.
