Epidemiology
Source of the outbreak(s) or origin of infection: Unknown or
inconclusive
Epidemiological comments:
On [3 Sep 2018], fattening pigs were found dead and reported to Gifu
Central Livestock Hygiene Service Centre (LHSC) by a veterinarian. On
[8 Sep 2018], the samples derived from pigs of reported farm tested
positive for Pestivirus by RT-PCR. But the result of pestivirus
specific FAT was negative. On the same day, the National Institute of
Animal Health (NIAH) carried out CSFV specific RT-PCR and FAT to
samples transported from Gifu City, and the result were positive and
negative respectively. On [9 Sep 2018], sequencing analysis of the
virus RNA was completed and the NIAH confirmed that this is the case
of classical swine fever. Note: Possibility of a case of African swine
fever was denied by NIAH. Movement and shipment restrictions are
imposed on the hog farms within a radius of 3 km [approx 1.8 mi] and
3-10 km [1.8 to 6.2 mi] of the affected farm respectively.
Stamping-out is being carried out on the affected farm.

Control measures
Measures applied: Movement control inside the country; surveillance
within containment and/or protection zone; screening; quarantine;
official disposal of carcasses, by-products and waste; stamping out;
control of wildlife reservoirs; disinfection; ante and post-mortem
inspections; vaccination prohibited; no treatment of affected animals
Measures to be applied: No other measures

[The following information comes from a special announcement by the
University of Minnesota's Swine Health Information Center (SHIC) dated
9 Sep 2018. The complete document, that included a map, is available
at <https://www.swinehealth.org/special-announcement-csf-japan/>

"The last CSF outbreak in Japan was in 1992 in Kumamoto Prefecture,
and in 2007 the use of vaccination was banned, and disease eradication
was declared in the country. The Japanese swine industry is still
recovering from the 2013-2016 PED epidemic. On 9 Jul 2018, APHIS
published the official notice of the OIE recognition of Japan as free
of CSF. Currently Japan exports pork, and it is in the top-10 pork
producing countries in the world.

"FAS/Tokyo estimates Japanese swine slaughter held stable at 16.336
million head in 2017.

"At this point, no other cases of CSF are suspected in Japan". -
