Worst-hit by hog cholera are the areas in the 3rd District in the north, as well as the 4th District in the south, particularly San Enrique town.

Negros Occidental remains free of African swine fever (ASF).

Classical swine fever (CSF) is a highly contagious, viral disease of swine that in its most virulent form causes morbidity and mortality approaching 100%. Viral strains of low to moderate virulence cause infections with a gradient of severity, some clinically inapparent.

Classical swine fever is highly contagious and infection spreads rapidly by direct or indirect contact between infected and susceptible pigs. Pigs with acute infection shed large amounts of virus before they are visibly ill, during illness, and after recovery. Live pigs infected as fetuses spread virus in their secretions and excretions. Uncooked waste food containing infectious pork scraps and subsequently fed to pigs has been well documented as initiating many outbreaks. Other methods of viral spread include farm equipment (contaminated wagons, trucks, tractors, machinery), personnel (careless farmers, salesmen, veterinarians), fomites, pets, birds and arthropods.

CSF does not affect humans even if meat from an infected animal is consumed.
