The Swine Health Information Center’s (SHIC) April Domestic Swine Disease Monitoring Report is available. This month’s Domestic Swine Disease Monitoring Report shows that porcine reproductive and respiratory syndrome virus (PRRSV) detection was similar to February. A substantial decrease in PRRSV detection in wean-to-market animals was observed. Based on PRRSV detection, ORF-5 sequences, and disease diagnosis reports, and also based on input from the advisory group, the PRRSV 1-4-4 Lineage 1C variant (144 L1Cv) situation is not further spreading or becoming an epidemic. We will continue to monitor the situation closely. March 2021 had a record-high number of cases tested for porcine delta coronavirus (PDCoV) in the US. PDCoV detection was the highest since the PDCoV-epidemic year of 2014. On the other hand, Mycoplasma hyopneumoniae reached the lowest level of detection for the year 2021. At the state level, PRRSV detection was three standard deviations above expected in Nebraska and Ohio. PDCoV was three standard deviations above expected in Kansas, Oklahoma, Missouri, and North Carolina. In a recorded interview, Drs. Trevisan, Magalhaes, and Linhares reflect on the main SDRS findings so far in 2021 and educate the users on how to use the newly launched disease diagnosis web-tool.
