Dangerous Cattle RSV Infection Detected on Pärnumaa Farm

A farm in Estonia's Pärnumaa county has confirmed a diagnosis of Bovine Respiratory Syncytial Virus (BRSV) among its cattle population. The outbreak was identified through laboratory testing after animals began falling ill in late May.

The affected animals, comprising adult heifers and cows, initially displayed symptoms such as listlessness, appearing dejected, and refusing to eat. These signs were soon followed by high fever, excessive tearing, and the development of pneumonia. Despite veterinary intervention and treatment efforts, the disease proved fatal for 18 of the farm's cattle.

While BRSV can cause significant distress and economic loss to livestock farmers, it is not classified as a particularly dangerous animal disease. However, the severity of the outbreak on this specific farm has led to a notable number of fatalities, underscoring the impact even less dangerous pathogens can have on herd health.
