Spesifikke virusinfeksjoner hos svin

Virussykdommene AD, TGE, PRCV, PRRS og PED har aldri vært påvist i Norge. Den norske svinepopulasjonen ble i 2009 smittet med pandemisk influensa A(H1N1)pdm09 virus. Etter det har ca 50 % av besetningene vært positive for antistoffer mot dette viruset.

Formålet med overvåkningsprogrammet er å dokumentere frihet for Aujeszkys sykdom (AD), smittsom gastroenteritt (TGE), porcint respiratorisk coronavirus (PRCV), porcint reproduksjons- og respiratorisk syndrom (PRRS), porcine epidemic diarrhoea (PED) og svineinfluensa virus (SI) (med unntak av influensa A(H1N1)pdm09 - hvor status dokumenteres).

2017

The surveillance programme for specific viral infections in swine herds in 2018 continued to show Norway to be free from Aujeszky’s disease, transmissible gastroenteritis, porcine epidemic diarrhoea virus and porcine respiratory and reproductive syndrome.

Norway recorded its first outbreak of influenza A (H1N1) pdm09 virus (H1N1pdm) in 2009, after which a stable herd prevalence indicated endemicity in the following years. For the first time since 2010, the national herd prevalence in 2018 fell below 40% at 25% (95% CI 22-30% or 138/ 534 herds) although the region of Rogaland and Agder with the highest number and density of pig herds, continued to have the highest herd prevalence at 50% (95% CI 41-58%). Except for H1N1pdm, Norwegian swine population was tested negative against other strains of influenza A virus that are endemic in most pig producing countries.
