OVERVIEW
Saint Valerien virus (SVV) is a recently described porcine calicivirus belonging to the genus Valovirus. It has been detected serologically and molecularly in pigs in multiple countries, but its role in clinical disease remains unknown.
FOODBORNE ZOONOTIC TRANSMISSION POTENTIAL
Level: No evidence of transmission
No evidence of foodborne zoonotic transmission.
NON-FOODBORNE ZOONOTIC TRANSMISSION POTENTIAL
Level: No evidence of transmission
No evidence of zoonotic transmission via occupational or environmental exposure.
DISEASE SPREAD BEYOND FARM BIOSECURITY CONTROL
Level: Farm biosecurity effective
Limited data exist; transmission is presumed pig-associated with no strong evidence of external amplification.
DIFFICULTY OF DETECTING AND CONFIRMING INFECTION
Level: Difficult: poor recognition and diagnostics
Detection relies on specialised molecular and serological tools primarily used in research contexts.
FINANCIAL IMPACT ON COST OF PRODUCTION
Level: Limited losses (few pigs)
No demonstrated association with clinical disease or production loss.
EFFECT ON DOMESTIC OR EXPORT MARKETS
Level: Little market disruption
No market or trade relevance.
PATHOGEN'S ABILITY TO DEVELOP AND SPREAD RESISTANCE
Level: Low resistance risk
Viral pathogen with no AMR relevance.
AMR DEVELOPMENT DRIVEN BY DISEASE MANAGEMENT
Level: Minimal: Rare or short-course individual treatments
Does not drive antimicrobial use.
AVAILABILITY OF EFFECTIVE TREATMENT OPTIONS
Level: No effective treatments
No treatments available or needed.
AVAILABILITY OF EFFECTIVE VACCINES OR BACTERINS
Level: No effective vaccine or bacterin available
No vaccines exist.
CAN THIS DISEASE BE ERADICATED FROM THE US?
Level: Extremely difficult and with uncertain success rate
Widespread exposure and uncertain disease relevance make eradication unrealistic.
