August 2, 2021
This month’s Domestic Swine Disease Monitoring Report shows a moderate decrease on the overall detection of porcine reproductive and respiratory syndrome virus (PRRSV) and the PRRSV RFLP 1-4-4 L1C variant strain. As expected by the forecasting models, there was lowering in the detection of enteric coronaviruses and a moderate increase in the detection of M. hyopneumoniae by PCR. There were also signals on the disease diagnosis for Mhp, based on diagnostic codes assigned by veterinary diagnosticians. Signals were also observed E. coli and salmonellas diagnosis. In the podcast, Drs. Trevisan, Magalhaes, and Linhares talk about PRRSV surveillance, management, control, and how to intervene to improve animal health.
July 6, 2021
This month’s Domestic Swine Disease Monitoring Report shows a moderate decrease on the overall PRRS virus detection. However, detection of the PRRSV RFLP 1-4-4 L1C variant strain continues to be very active in the midwestern region, especially in the wean-to-market age category. A new tool to compare RFLP vs. lineage detections has been launched on the SDRS project website (www.fieldepi.org/SDRS). A moderate decrease in detection of PDCoV and PEDV was observed in June. In the podcast, SDRS hosts talk with Dr. Montserat Torremorell about her experience on surveillance of Influenza A, her thoughts on the PRRSV RFLP 1-4-4 L1C variant strain epidemic, and how to intervene to improve animal health.
June 1, 2021
This month’s Domestic Swine Disease Monitoring Report shows that porcine reproductive and respiratory syndrome virus (PRRSV) continues to be very active, especially in wean to market age category. A second wave of detections for the PRRSV RFLP 1-4-4 L1C variant strain was detected. After a couple of months with a continued increase in detection of PDCoV, during May PDCoV detection has had a moderate decrease in the age categories adult/sow farm and wean to market. The advisory group has shared their practical points for preventing a new wave of pathogens activity for the upcoming fall and winter seasons in the report as well. In the podcast, the SDRS hosts talk with Dr. Paul Yeske about his experience on handling the PRRSV RFLP 1-4-4 L1C variant strain since its emergence and in the second wave and how to intervene to improve animal health.
May 4, 2021
This month’s Domestic Swine Disease Monitoring Report shows that porcine reproductive and respiratory syndrome virus (PRRSV) had a moderate increase in detection from March. Porcine delta coronavirus (PDCoV) activity observed since January is explained by increased testing following outbreaks observed in sow farms and viral activity in grow-finish animals. In the SDRS data, a site may have turned positive, kept submitting samples for testing, and obtained positive results over time but information on the incidence level was not known. Higher incidence is assumed because of the positivity in some regions. During the last year, since May 2020, only eight cases tested positive for transmissible gastroenteritis virus (TGEV). Mycoplasma hyopneumoniae was within expected levels for this time of year. At a state level, PRRSV detection was three standard deviations above expected in Nebraska, Ohio, and North Carolina; and PDCoV in Kansas, Oklahoma, Missouri, and North Carolina. In the podcast, the SDRS hosts talk with Dr. Eric Burrough about disease diagnosis coding and trends, and implications for researchers, diagnosticians, and practitioners.
April 5, 2021
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.
March 2, 2021
This month’s Domestic Swine Disease Monitoring Report shows that porcine reproductive and respiratory syndrome (PRRS) virus detection was similar to January 2021, with a small decrease in positivity in sow herds, but increase in wean-to-market animals. PRRSV RFLP 1-4-4 Lineage 1C variant continues to be associated with severe clinical signs, especially in grow-finish sites. There was a moderate increase in detection for porcine deltacoronavirus (PDCoV) in wean-to-market animals. That increase was regional. There was a moderate decrease in Mycoplasma hyopneumoniae. At a state level, PRRS virus detection was three standard deviations above expected in Nebraska, Ohio, and Indiana; and PDCoV was three standard deviations above expected in Kansas, Oklahoma, and North Carolina. The SDRS hosts talk with Dr. Cesar Corzo (Morrison Swine Health Monitoring Project) about his observations on recent pathogen activity in the US swine herd.
February 4, 2021
This month’s Domestic Swine Disease Monitoring Report shows that porcine reproductive and respiratory syndrome virus (PRRSV) detection had a moderate decrease from December 2020 to January 2021, mostly contributed by a substantial decrease in detection in wean-to-market animals. There was a moderate increase in detection for porcine deltacoronavirus (PDCoV) in adult/sow farm animals. There was a moderate decrease in Mycoplasma hyopneumoniae. At a state level, PDCoV detection was three standard deviations above expected in Kansas and Oklahoma. Drs. Trevisan, Magalhaes, and Linhares reflect on the main findings and contributions of the SDRS to the swine industry in 2020, and leak some of what is cooking for 2021 in the related podcast.
January 4, 2021

December 1, 2020
This month’s Domestic Swine Disease Monitoring Report shows porcine reproductive and respiratory syndrome virus (PRRSV) detection was on the upper boundaries of the forecasted model at the end of October and beginning of November, mostly from a substantial increase in detection from wean-to-market animals. During November, a moderate increase in PRRSV detection in the age category adult sow farm was observed. The October detection levels for porcine epidemic diarrhea virus (PEDV), porcine deltacoronavirus (PDCoV), and Mycoplasma hyopneumoniae (MHP) were similar from October. At a state level, PRRSV detection was three standard deviations above expected in Minnesota, Iowa, South Dakota, Nebraska, Missouri, and Indiana. A seasonal increase in the number of disease diagnosis for PRRSV, Influenza A, S.suis, G.parasuis, B. bronchiseptica, and P. multocida was detected. In the podcast, the SDRS hosts talk with Dr. Clayton Johnson, of Carthage Veterinary Services, about his experiences in using and applying veterinary diagnostic data for disease management and control.
November 3, 2020
This month’s Domestic Swine Disease Monitoring Report shows a moderate increase in case positivity for porcine reproductive and respiratory syndrome virus (PRRSV), mostly contributed by a substantial increase in detection from wean-to-market animals. The October detection levels for porcine epidemic diarrhea virus (PEDV), porcine deltacoronavirus (PDCoV), and Mycoplasma hyopneumoniae were similar from September. At a state level, PRRSV detection was three standard deviations above expected in Minnesota, Iowa, South Dakota, Nebraska, Missouri, Illinois, and Indiana.

Detection for these agents was within expected parameters for this time of the year. Overall, Mycoplasma hyopneumoniae is following an expected trend of increased detection. At the state level, detection of PRRSV was three standard deviations above expected in Missouri (MO). In the podcast, the SDRS hosts talk with Dr. Derald Holtkamp about strategies to keep disease activity low. They also discuss the economics of disease management and the value of year around biosecurity practices.
August 4, 2020
This month’s Domestic Swine Disease Monitoring Report shows a moderate decrease of porcine reproductive and respiratory syndrome virus (PRRSV) cases in July compared to June, down substantially in wean-to-market category. Porcine epidemic diarrhea virus (PEDV)-positive cases were down moderately in July compared to June as well and within expected boundaries for this time of year. Detection of porcine delta coronoavirus (PDCoV) was also within the expected boundaries for this time of year. Mycoplasma hyopneumoniae (MHP)-positive cases in July were similar June and also within expected boundaries.
July 7, 2020
In the July Domestic Swine Disease Monitoring Report, we learn porcine reproductive and respiratory (PRRS) virus cases dropped in June compared to May. Overall detection of PRRSV-positive cases was in the upper boundaries of the forecasted levels for the first three weeks of June. The overall percentage of porcine epidemic diarrhea virus (PEDV) RNA-positive cases in June also decreased compared to May and were within expected boundaries of forecasted levels for this time of year. Porcine delta coronoavirus (PDCoV) cases were just slightly lower in June compared to May and there was one positive case of TGEV RNA in June 2020. Mycoplasma hyopneumoniae-positive cases in June were within the forecasted levels for this time of year.
June 2, 2020
In the June Domestic Swine Disease Monitoring Report, we learn the overall percentage of porcine reproductive and respiratory syndrome virus (PRRSV) positive cases in May was similar to the previous month. Wean-to-market cases were slightly up. Comparing January – April 2020 to the same four months of 2019, the number of PRRSV cases was up 6.49%. The overall percentage of porcine epidemic diarrhea virus (PEDV) RNA-positive cases in May was down compared to April, however, this was not the case for the adult/sow category where detection remained similar to the prior month. The overall percentage of porcine delta coronavirus (PDCoV) positive cases in May was down compared to April as well and within forecasted levels for this time of year. Mycoplasma hyopneumoniae (MHP) positive cases in May were within the forecasted levels, also.
May 5, 2020
Porcine reproductive and respiratory syndrome virus positive cases in April were down over March per the most recent Domestic Swine Disease Monitoring Report (DSDMR) and within the forecasted levels for this time of the year. The DSDMR advisory group pointed out COVID-19-related packing plant shutdowns have led to the retention of animals in the field and caused negative market impact. They also noted this may affect the implementation of health interventions, as well as cause disruptions of pigs and people flows. Altogether, these factors can lead to increased pressure of pathogen infection in the field in the near term. Porcine epidemic diarrhea virus (PEDV) and porcine deltacorona virus (PDCoV) cases were also down in April compared to March. Both were in forecasted levels for this time of year. The overall percentage of Mycoplasma hyopneumoniae positive cases in April was within the forecasted levels, down from March levels.
March 4, 2020
In this month’s Domestic Swine Disease Monitoring Report, the overall percentage of porcine reproductive and respiratory syndrome (PRRS)-positive cases in February were down from January in all age groups and sample types. It was noted genetic variability of PRRSV is still increasing. Porcine epidemic diarrhea virus (PEDV) RNA-positive cases in February were up from January in Iowa, Illinois, and Minnesota. The overall percentage of porcine deltacorona virus (PDCoV)-positive cases was down from January. Both PEDV and PDCoV positive cases are within forecasted levels for this time of year. Mycoplasma hyopneumoniae (MHP)-positive cases in February were down from January in all age categories. MHP detection also followed the expected predicted decrease for this period of the year.
February 5, 2020
In the February report, we learn porcine reproductive and respiratory syndrome (PRRS) positive cases reported in January were down compared to December in all age groups and sample types. This data corresponds to the Morrison’s Swine Health Monitoring Program which reports a relatively low PRRS incidence in sow farms compared to previous years. The overall percentage of porcine epidemic diarrhea virus (PEDV) RNA positive cases in January was slightly up from December with increased detection observed in cases from Minnesota and North Carolina. The overall percentage of porcine deltacorona virus (PDCoV) positive cases in January was slightly down from December. Both PEDV and PDCoV RNA positive cases are within forecasted levels for this time of year. The overall percentage of Mycoplasma hyopneumoniae positive cases in January was slightly up from December, mostly driven by samples with unknown information for age category.
December 3, 2019
In the December report, the percentage of positive porcine reproductive and respiratory syndromve virus (PRRSV) cases in November was 26.15%, up from 22.65% in October, with increased detection in all age categories. The increase follows the predicted expectation for the period. Porcine epidemic diarrhea virus (PEDV) overall positive cases in November were at 13.97%, up from 10.82% in October. The increased detection of PEDV RNA was above expected, mostly driven by wean-to-market animals. The overall porcine deltacorona virus (PDCoV) percentage of positive cases in November was at 4.18%, up from 2.13% in October. There was a signal for increased detection of M. hyopneumoniae above expected in November. Details on these and other monitoring results are included in the full report.
November 5, 2019
Porcine reproductive and respiratory syndrome (PRRS) positive cases were up in October over September in all age categories, per seasonal expectations. Porcine epidemic diarrhea virus (PEDV) and porcine delta corona virus (PDCoV) detection in October also increased as expected. Mycoplasma hyopneumoniae (MHP) positive cases were slightly higher than expected for October. From September 1 to October 19, there was an increased number of cases diagnosed with Influenza virus A at the Iowa State University Veterinary Diagnostic Lab, though it is not associated with more severity of the disease.
May 7, 2019
The Swine Health Information Center’s Domestic Swine Disease Monitoring Report for May 2019 shows PRRSV activity remained within the predicted values for 2019 to date. The level of detection of PEDV by PCR was within expected values for April with a 3 percentage point drop in positive results from March to April this year. PDCoV detection level was above expected in mid-April and Monitoring Report advisors said some sow farms experiencing outbreaks had clinical signs of the virus. Streptoccoccus suis (S. suis) continues to be the major agent detected on CNS tissue, however, in March and April there were an increased number of Pestivirus, Porcine Sapelovirus, and salt intoxication detections on CNS tissue when compared to the same time frame in 2018 and 2017. There was also an increase in detection of the following respiratory insultants this spring compared to 2018: Haemophilus parasuis, Actinobacillus pleuropneumoniae, Pasteurella multocida, and Mycoplasma hyorhinis.
February 4, 2019
The Swine Health Information Center’s Domestic Swine Disease Monitoring Report shows both porcine reproductive and respiratory virus (PRRSV) and porcine epidemic diarrhea virus (PED) are being reported at expected levels. PRRSV has been stable since October 2018. And while PED has been at expected levels, there has been a slight increase in reported cases over the last three months. There was a high detection of porcine deltacoronavirus in the second week of January 2019. And porcine circoviruses (PCV2 and 3 combined) and Bordetella bronchiseptica have both been diagnosed at higher levels than the previous two winter seasons.
January 9, 2019
The Swine Health Information Center’s Domestic Swine Disease Monitoring Report this week shows expected activity in December. Data for the report is collected from the Veterinary Diagnostic Labs at Iowa State, South Dakota State, and Kansas State Universities as well as the University of Minnesota. Porcine reproductive and respiratory syndrome detection decreased in December after two months of increase and remained in the predicted range the last three weeks of 2018. Porcine epidemic diarrhea virus detection by PCR also continues to meet expected values which means an increase in activity for the same time frame based on previous years’ reports. Streptoccocus suis remains the major agent causing CNS. For the beginning of 2019 winter, porcine circovirus had a greater percentage of detection, but similar number of cases, when compared with full winter season of previous years.
December 4, 2018
Few monitored diseases were above expected or predicted level in the November domestic swine disease report from the Swine Health Information Center (SHIC). Porcine reproductive and respiratory virus was one of those above expected levels. A trend to increasing positivity in adult/sow and unknown categories was noted. There was a spike in porcine delta corona virus PCR positive tests but only a limited number of transmissible gastro enteritis cases. Accession ID cases investigated for central nervous system (CNS) issues rose with nearly 9 percent more in November 2018 than the same month in 2017. The number of cases per agent have similar distribution this fall, compared to the same season of previous years. Streptoccocus suis is still the major agent causing CNS. Detection of influenza A (IAV) as a single agent was less frequently detected in 2018 than previous Fall seasons of 2017 and 2016.
May 2, 2018
There has been a recent increase in cases testing positive for PRRS virus by rRT-PCR. The domestic disease monitoring project advisory group reached consensus that this is possibly due to a) increased use of processing fluid to monitor sow herds, and b) increased PRRS virus activity in grow/finish pigs. There has been a significant increase of processing fluids to test for PRRS virus on sow farms. This specimen was not reported in previous years, and in 2018 accounted for more than 5 percent of total the submissions at the participating VDLs for PRRS rRT-PCR testing.
Deltacoronavirus (PDCoV) activity continues high relative to predicted values based on previous years. There was a 19 percent increase in the number of Central Nervous System (CNS) cases in 2017 compared to 2016. Partial data for spring 2018 indicates a 30 to 40 percent increase in CNS disease compared to spring months of 2017. Streptoccocus suis has been the main pathogen associated with CNS disease.
The May Swine Health Information Center-funded Domestic Swine Disease Monitoring Report PRRS data now includes data from the Iowa State University and University of Minnesota veterinary diagnostic labs. Work to integrate other disease information and laboratories into the report continues.
March 1 ,2018
The Swine Health Information Center (SHIC) has posted the first monthly domestic swine disease monitoring report. The report is the result of the veterinary diagnostic lab (VDL) data standardization project SHIC supported. Beginning with monitoring of PEDv, PDCoV, and PRRS, the model describes dynamics of disease detection by pathogen over time, specimen, age group, and geographical space. Additional diseases will be included as the program is refined.
The domestic monitoring report is a SHIC-funded, veterinary diagnostic laboratory collaborative project. An advisory group has been formed to help give context to the data and interpret it. The goal is to aggregate swine diagnostic data from participating reporting VDLs then present it in an intuitive format via shared reports and web dashboards. The report uses data from VDL cases with molecular tests (PCR-based assays and virus genotyping) for these viruses. For this first report, all data was from the Iowa State University Veterinary Diagnostic Laboratory. The University of Minnesota VDL will incorporate their data beginning with the next report.
To implement infectious disease control and management, precise, science-based information is required. By funding this project, SHIC leads the industry toward better swine health information to positively impact the long-term sustainability of pork production. The near real-time information on swine disease made available by this system will enable better, faster, and more effective response to endemic or foreign infectious diseases. The result is a stronger, more vibrant U.S. pork industry.
