[0002] Pseudorabies in pigs is caused by pseudorabies virus, which is an acute infectious disease that is very harmful to pigs. It can cause miscarriage, stillbirth or mummification in pregnant sows. Newborn piglets are mostly acute and fatal, with obvious neurological symptoms. Pseudorabies in pigs is mainly transmitted through the digestive tract and respiratory tract, and can also be transmitted through mating, semen, and placenta. The virus can be transmitted through direct contact, and is more easily transmitted indirectly, such as inhaling aerosols containing virus particles and drinking contaminated water.
