A farrow to finish facility experienced increased mortality, diarrhea, wasting, and pallor in finishing pigs, and it was identified to be H3N2. The first intervention was to give H1N1 and H3N2 vaccines to sows, obtain gilts at 5-20 kg and expose them to the herd to develop immunity, improved hygiene and sanitation, and reduced mixing and cross fostering. The first intervention gave no noticeable improvement, so litter and pen integrity was maintained, pig mixing was reduced, and PCV2 piglet vaccines were tried.
