France had previously reported 67 outbreaks, and Italy 47. This disease is not transmitted to humans.

The Catalan government's Ministry of Agriculture, Livestock, Fisheries and Food stated that the disease was confirmed through tests conducted at the Algete Central Veterinary Laboratory in Madrid.

To contain the outbreak, the Catalan Government implemented a set of measures, including monitoring the area where the disease was detected to prevent its spread to neighbouring farms.

The virus is transmitted primarily by flies, mosquitoes, and ticks, but also through direct contact with sick and healthy animals. Indirect transmission, for example, through contaminated water and food, is also possible. The most common symptoms of NCD are fever, anorexia, excessive salivation, nasal discharge, and decreased milk production. Lesions may appear in the animals in the form of nodules and swellings.

The mortality rate is approximately 10%. However, there is no treatment for the disease, and vaccination is prohibited in the European Union except in emergency cases.
