African Swine Fever and the Diagnostics Response

African swine fever has become one of the most feared diseases in global agriculture. It is highly contagious, has a high mortality rate, and there is currently no widely available vaccine. Once introduced into a herd, it can spread rapidly, and controlling it often requires culling entire populations. The disease has swept through parts of Asia and Europe, causing severe economic damage and reshaping pork supply chains. In this environment, diagnostics are the first and most important line of defense.

Detecting ASF early requires rapid, accurate testing. PCR-based assays are the gold standard for confirming infection, allowing detection of viral DNA in blood, tissue, and environmental samples. Serological tests can identify animals that have been exposed and survived. Surveillance programs combine on-farm sampling, abattoir testing, and monitoring of wild boar populations, which can act as reservoirs. The scale of testing required during an outbreak is enormous, which has driven investment in laboratory capacity and rapid test development. Reflecting this, the Swine Diagnostic Testing Market has expanded significantly, with governments and producers prioritizing diagnostic readiness.

The broader lesson from ASF is that biosecurity and diagnostics must work together. No amount of testing can compensate for weak farm biosecurity, and no biosecurity program is complete without a testing capability to verify its effectiveness. Countries that invested early in both have generally fared better during outbreaks. As the disease continues to circulate globally, diagnostic innovation — including portable tests suitable for field use — remains a critical priority.

People Also Ask

How is African swine fever diagnosed?
ASF is typically diagnosed using PCR testing to detect viral DNA, supported by serological tests and post-mortem examination when appropriate.

Is there a vaccine for African swine fever?
As of recent years, no widely available commercial vaccine exists, though research is ongoing. Control relies primarily on biosecurity, culling, and rapid diagnosis.
