PMWS was first reported in Denmark in 1999 and is now present in 30% of Danish swine herds. The disease is responsible of heavy economic loss due to high mortality rates reaching 20% and wasting. Madec's control measures of which especially colostrum intake, reduction of mixing and improved management, were implemented. Providing vitamin E at weaning, improving disinfection, using more gentle vaccines and eliminating affected animals are additional measures than can improve the situation. Genetics may play a role as well since Hampshire Duroc crossbreeds seems to be more resistant to PMWS. In Denmark, serum therapy is not authorized by law, but studies carried out by Dalby out of Denmark have given interesting results. However, this technique remains quite laborious.
