Classical swine fever
Classical swine fever (CSF) or hog cholera is a highly contagious viral disease of pigs and wild boar. The virus is harmless to humans. Wageningen Bioveterinary Research conducts research on this disease.
Severity of symptoms mainly depends on the age of the animal and virus virulence. Classic swine fever often leads to death in young animals.
Since 1997/1998, the Netherlands has been free of CSF. Classical swine fever is a notifiable disease in the Netherlands. This means that suspicions of infection must be reported to the NVWA.
Clinical signs classical swine fever
The clinical signs of classical swine fever are extremely variable and may be mistaken for many other diseases. CSF causes fever, conjunctivitis, skin lesions, convulsions and often (particularly in young animals) leads to death of the animal within less than four weeks.
Severity of symptoms mainly depends on the age of the animal and virus virulence. Usually young animals are affected more severely than older animals. In older breeding pigs the course of the infection is often mild or even subclinical.
The symptoms are indistinguishable from those of African swine fever.
