NA PRRS Symposium

EMERGING AND FOREIGN DISEASES OF SWINE

December 4, 2021

Chicago Marriott Downtown Magnificent Mile Hotel
540 North Michigan Avenue
Chicago, IL 60611

The North American PRRS Symposium was initiated in November 2003 as the “International Workshop on PRRS”. The conference continues to focus on the latest knowledge and novel tools for the control of PRRS, one of the most costly viral diseases to ever face a global swine industry. In recent years, the emergence of new swine viruses, including the PEDV and ASFV, has expanded the topics of this symposium to emerging and foreign swine diseases. The symposium has integrated with NC229, which provides the means to deliver a much larger and more comprehensive meeting experience.

This very successful meeting is attended by an internationally recognized group of scientists, researchers, industry and academic professionals and students.

This year’s event will be scheduled in connection with the Conference of Research Workers in Animal Diseases (CRWAD).
