The Swine Health Information Center is warning hog producers and swine veterinarians that there is a second wave of a new PRRS virus, strain 144, threatening herds.
Executive Director Dr. Paul Sundberg said this strain is especially virulent and has caused a lot of problems in the U.S. Midwest and upper Midwest.
It causes very severe disease in all phases of production so that's something that is notable, he said.
It's PRRS but it's in all phases of production and does cause disease.
