Key Takeaway
Consider host-directed strategies as layered additions, not replacements, for ASF and SI control.
This meta-review examines preventive and host-directed strategies for African swine fever (ASF) and swine influenza (SI) in swine. It synthesizes evidence across surveillance, vaccination where applicable, biosecurity, herd management, supportive care, nutritional and immune-supportive measures, and host-directed regenerative approaches.
The strongest field-supported evidence centered on surveillance, vaccination where applicable, biosecurity, and production-system management. Regenerative and host-supportive biologic strategies, including mitochondria-targeted peptides, thymic and organ-derived peptides, extracellular vesicle-based approaches, and stem cell-related therapies, show growing translational and immunomodulatory relevance. Reported secondary outcomes include immune resilience, reduced infection pressure, preserved immune competence, regulated inflammatory responses, and tissue recovery capacity.
For ASF, control depends on preventing viral introduction and limiting outbreak dissemination. For SI, management benefits from integrated vaccination, environmental optimization, mitigation of secondary bacterial disease, and adaptation to antigenic evolution.
The review cautions that immune resilience is not a replacement for conventional disease control but a layered outcome. No effect sizes, absolute numbers, p-values, confidence intervals, adverse events, or follow-up data were reported. Limitations, funding, and conflicts of interest were not reported.
How this fits prior evidence
This meta-review extends prior coverage of CRISPR/Cas9 screening that identified shared host pathways such as interferon signaling as targets for broad-spectrum antivirals, by cataloging host-directed and regenerative strategies alongside conventional control. It also aligns with prior coverage of distinct transmission drivers and varied national control strategies for ASF and PRRS in Asian swine industries, reinforcing that ASF control depends on preventing viral introduction and limiting outbreak dissemination. The review does not provide pooled effect sizes, so it cannot confirm or contrast quantitative estimates from earlier findings.
Managing diseases like African swine fever and swine influenza is a major challenge for the farming industry. These illnesses can spread quickly and cause significant damage. To fight back, experts are looking at a mix of traditional methods and newer, high-tech biological approaches.
The review shows that the strongest evidence currently comes from solid basics: constant surveillance, vaccination where possible, and strict biosecurity. These methods focus on keeping the virus out and stopping it from spreading through a herd. For swine influenza, managing the environment and treating secondary bacterial infections are also key parts of the strategy.
There is also growing interest in host-directed therapies. These are treatments that help the animal's body fight the infection more effectively. This includes things like stem cell-related therapies and peptides that support the immune system. While these new methods are still moving toward practical use, they offer a way to build more resilient herds by supporting the body's natural ability to recover.
What this means for you:
Combining strict biosecurity with new immune-supportive treatments helps manage swine diseases more effectively.
Common questions
What are the most effective ways to control swine diseases?
The strongest evidence currently focuses on four main areas: surveillance, vaccination where it is applicable, biosecurity, and managing the production system. These methods work together to prevent viruses from entering a farm and limit how quickly an outbreak spreads if it does occur.
What are host-directed therapies in swine health?
Host-directed therapies are strategies that help the animal's body fight infection and recover. These include things like stem cell-related therapies and peptides that target the immune system. These methods aim to improve the animal's ability to handle stress and recover from disease.
How is swine influenza managed differently than other infections?
Managing swine influenza specifically benefits from a combination of vaccination, improving the environment, and treating secondary bacterial diseases. It also requires adapting to how the virus changes over time to keep the herd healthy.
African swine fever (ASF) and swine influenza (SI) are among the most consequential infectious threats to global swine production because they combine major economic burden with fundamentally different transmission ecology, tissue tropism, and immune-pathological behavior. ASF is a highly lethal systemic disease characterized by macrophage tropism, immune dysregulation, environmental persistence, and severe trade and production consequences, whereas SI is a highly transmissible respiratory infection associated with recurrent herd-level morbidity, viral evolution, and zoonotic significance. Although these diseases differ markedly in biology and field presentation, both highlight the limitations of isolated pathogen-centered control strategies when implemented without integrated herd-level resilience measures. This meta-review synthesizes the cited literature into an evidence-based framework encompassing epidemiology, pathogenesis, surveillance, vaccination, biosecurity, herd management, supportive care, nutritional and immune-supportive measures, and host-directed regenerative approaches. Across the reviewed literature, the strongest field-supported evidence remains centered on surveillance, vaccination where applicable, biosecurity, and production-system management. At the same time, regenerative and host-supportive biologic strategies, including mitochondria-targeted peptides, thymic and organ-derived peptides, extracellular vesicle-based approaches, and stem cell-related therapies, demonstrate growing translational and immunomodulatory relevance within the broader context of immune resilience and recovery support. Comparative analysis further demonstrates that intervention priorities must remain aligned with disease biology: ASF control depends primarily on preventing viral introduction and limiting outbreak dissemination, whereas SI management benefits from integrated vaccination strategies, environmental optimization, mitigation of secondary bacterial disease, and continual adaptation to antigenic evolution. Within this framework, immune resilience is best understood not as a replacement for conventional disease control, but as a layered outcome arising from reduced infection pressure, preserved immune competence, regulated inflammatory responses, tissue recovery capacity, and supportive production practices.
