Porcine Respiratory and Reproductive Syndrome: the main cause of losses on pig farms. Is it forever?

Porcine Respiratory and Reproductive Syndrome virus has been defined as the primary disease causing economic losses in the Swine Industry. The terrible impact of PRRSv is due to mortality, abortions and respiratory problems in the affected farms.

The cost of Porcine Reproductive and Reproductive Syndrome virus in the US has been estimated as $664 million annually. During 2014, PRRSv outbreaks have been reported in Asia, Europe and America, being the main problem in different surveys for swine veterinarians worldwide:

 

The most frequent routes of transmission between herds are the introduction of infected animals and the use of contaminated semen. Nevertheless, indirect transmission of PRRSv has been verified by several routes. Vectors, personnel, etc.

As with other members of the Arterivirus, pigs can shed the virus at low levels or intermittently:

Semen can play a crucial role in transmission. This is due to the special features of the virus shedding by this route and the extensive use of artificial insemination.

If you want to avoid the risks and economic losses associated with Porcine Respiratory and Reproductive Syndrome virus, be excellent in your biosecurity procedures, use available vaccines when needed, and always ask your vet for more information. Genetic variability and a high virus transmission rate are the reasons why this disease is selected as the main health problem by veterinarians for the coming years.
