The age at which animals become infected plays a role in establishing persistent infection with the Classical Swine Fever virus, with older animals being less susceptible to developing persistent infection with VPPC.

In a recent study, published in the journal Transboundary and emerging diseases, it has been shown that piglets born from a sow without pestivirus and that have been infected with the Cat01 strain at 21 days of age can also develop persistent infection with the VPPC. This age of infection is important, since 21 days after birth the animals are weaned and together with piglets from other litters in some farms, where they could spread the disease.
Classical Swine Fever continues to be one of the most important diseases for animal health worldwide, generating high economic losses due to the costs derived from the death of the animals, as well as the eradication efforts.
