Clinical signs include non-specific illness (anorexia and dullness) in sows, with reproductive losses occuring 1-2 weels later. In piglets, PRRS is characterised by inthriftiness, respiratory illness and mortality. Signs are similar in all ages of growing stock. Effects on neonatal piglets can be severe. Respiratory distress is seen, in addition to scour, unthriftiness and high mortality. Infection of boars may lead to impaired semen quality. Blue ears, snout and vulva can be seen in 1-5% of sows. Reproductive problems include infertility (normal oestrus delated, retuns to service increased), premature farrowing, stillbriths and weakly piglets.
