#13,994

Japan reported 6 new outbreaks over the last 10 days of March, but all has been quiet on the CSF front for the first week of April.  That lull ends today with the 18th farm outbreak reported since the virus re-emerged in Japan - after an absence of 26 years - last September.

Classical Swine Fever is caused by a highly contagious (among pigs, not people) Pestivirus in the family Flaviviridae. Clinically similar to African Swine fever, both viruses can have a devastating impact on the pork industry.

First a look at the latest report from Japan's Ministry of Agriculture (MAFF), then a look at yesterday's OIE recap of CSF in wild boar.
