This virus does not affect humans, but is highly contagious in cattle. BVDV can be catastrophic for pregnant cows, as it can infect developing calves, leading to spontaneous abortion and low birth rates. Some infected calves survive to birth and are infected for life, spreading large amounts of virus to other cattle. Although vaccines are available, controlling transmission remains a challenge. In order to control the spread of BVDV, nucleic acid collection needs to be carried out on the cattle herd.
