|Signs and symptoms of piglets infected with PEDv - Credit CDC Emerging Infectious Diseases Journal|
They agricultural ministry is expecting more pigs to test positive for the virus and are fearful of the overall toll, as PEDv has been responsible for killing millions of piglets in the U.S. in recent years.
Meanwhile in the United States...
PEDv is making its way across the Midwest, now including Minnesota. PEDv killed more than 7000 pigs at a facility near Good Thunder, MN in December 2013. Newborn piglets appear to be the most susceptible and it is has a very high mortality rate. The damage to the Good Thunder facility was estimated to be $500,000 USD.
Empirical evidence suggests that the disease will continue to spread, especially in the north, until warm weather breaks the cycle.
The University of Minnesota Swine Disease Eradication Center has some wonderful information on PEDv
- PEDv was confirmed in the United States the week of May 13, 2013
- PEDv has caused outbreaks in Europe possibly as early as 1971 and was identified in Asia as early as 1982
- PEDv is a member of the Coronaviridae family
- Incubation in individual pigs may be as short as 22-36 hours or 2-4 days at the herd level
- Characterized by severe diarrhea and vomiting, significant mortality (50-100%) in suckling piglets under seven days of age (pigs older than seven days often recover)
- Virus can be transmitted directly or indirectly by contaminated fomites (footwear, clothing, farm supplies, and vehicles)
- PEDV is only infectious to swine
- There is no concern for human safety
