Intensified pork production increases swine viruses like Porcine circovirus type 3 (PCV3) spread. This review addresses PCV3 epidemiology, classification challenges, and public health implications.
Area of Science:
- Veterinary Virology
- Animal Health
- Public Health
Background:
- Intensified pork production drives environmental changes and increased human-animal-wildlife contact.
- This scenario facilitates the spread of potent viral species, including Porcine circovirus type 3 (PCV3).
- Emergence of new pathogenic agents and variants poses risks to animal and public health.
Purpose of the Study:
- To review existing literature on Porcine circovirus type 3 (PCV3) infections.
- To explore key aspects of PCV3 epidemiology and clinical manifestations.
- To identify and highlight critical knowledge gaps and unanswered questions regarding PCV3.
Main Methods:
- Comprehensive literature search on PCV3.
- Analysis of studies focusing on PCV3 epidemiology, classification, and impact.
- Synthesis of current knowledge and identification of research needs.
Main Results:
- PCV3 emergence is linked to intensified agricultural practices.
- Challenges exist in PCV3 classification, necessitating standardized terminology.
- Understanding PCV3's evolving epidemiology is crucial for disease control.
Conclusions:
- Enhanced understanding and control strategies for PCV3 are urgently needed.
- Establishing common terminology for PCV3 classification is vital for research comparability.
- Transparent and reproducible research approaches are essential for public health impact.
