This is a short review of the book Porcine Reproductive and Respiratory Syndrome (PRRS). When PRRS was first discovered it caused a large amount of concern and even more when it was found in Germany in 1990. Since then a lot has been learned about the virus that is responsible for the disease and it is recognized as a disease to be lived with rather than eliminated. Fortunately the disease was not as severe for most farms as originally feared. This does not take away from the importance of the work being done to understand the disease. The author of the review believes it is an important book for swine veterinarians.
