Swine can shed CSFV in the incubation period
T
Skin suffusions and haemorrhages are signs of Classical Swine Fever
T
Skin suffusions and haemorrhages are signs of Classical Swine Fever.

Contaminated pork meat can play a role in the transmission of CSFV.
T
Attenuated vaccines are developed for immunization of swine against CSFV
T
All known strains of the Classical Swine Fever virus are of highly virulence

Classical swine fever virus is shed with faces, when boutons appear in the intestines
F
Classical swine fever can be eradicated from wild boar populations by oral vaccination
F
Classical swine fever virus is rarely complicated by secondary infections
F
Classical swine fever can be diagnosed easily by the characteristic symptoms and lesions

T
Classical swine fever virus causes lympho-histiocytic encephalitis in carnivores
F
Classical swine fever Virus spreads slowly in the host and causes mainly chronic disease
F
Complicated forms of the Classical swine fever are rarely seen
F
Classical swine fever can unambiguously diagnosed by the clinical signs and pathology
F
Low virulence strains of CSFV may lead to asymptomatic infection
T
CSF is spread via infected pigs
T
Sows infected by CSF will have immunotolerant piglets
(In first half of pregnancy yes but not in second half… so T and F)
