UP until 1991, the British pig herd had enjoyed a period of health that was not complicated by major persistent viral involvement. In May 1991, porcine reproductive and respiratory syndrome (blue-eared pig disease) appeared in this country, followed at the end of 1991 by the emergence of a swine influenza virus strain that was a variant of the H1N1 swine strain seen since 1986 and designated H1 195852. Since then, a syndrome of disease in pigs in the immediate post weaning period has assumed a major role in pig production in Great Britain under many different husbandry systems. It is referred to variously as blue flu, chronic respiratory disease, post weaning respiratory syndrome or fading weaner syndrome.
