Swine Infertility Respiratory Syndrome Virus (SIRSV) is a highly contagious viral disease that primarily affects pigs and is characterized by infertility and respiratory symptoms. SIRSV is a member of the family Arteriviridae and the genus Arterivirus.
SIRSV is transmitted through direct contact with infected animals, respiratory secretions, and contaminated objects such as equipment and clothing. It can also be spread through aerosol transmission, allowing the virus to be easily disseminated within a swine population. Infected sows can transmit the virus to their piglets through the placenta during pregnancy, resulting in a high rate of stillbirths, abortions, and mummified fetuses. Infected boars may experience a decrease in fertility, leading to reduced conception rates.
Respiratory symptoms associated with SIRSV infection include coughing, sneezing, nasal discharge, and difficulty breathing. These symptoms can cause significant economic losses in pig production due to decreased feed intake, weight gain, and overall growth performance.
There is currently no specific treatment for SIRSV, and control measures primarily focus on prevention and biosecurity. Vaccination programs can be implemented to reduce the severity of the disease and limit its spread. Improved hygiene and strict quarantine measures are also essential in preventing the introduction and dissemination of the virus within pig populations.
Due to its impact on reproductive efficiency and respiratory health in pigs, SIRSV is a significant concern for the swine industry worldwide. Active surveillance, early detection, and prompt control measures are vital to minimizing the economic losses associated with this viral infection.
