At the end of November, Senasa established a state of emergency in our country due to the spread of Equine Encephalomyelitis. In Río Negro there were four suspected cases and during this day two deaths from this disease were confirmed.

These are two cases in Viedma which have already been confirmed by the national body. At the beginning of this month, samples of cerebrospinal fluid and brain had been sent due to the suspicion of the Alphavirus outbreak.

They are a horse and a mare from the Idevi farm area who in the first days of December presented symptoms compatible with Equine Encephalomyelitis. Is about a viral disease that is transmitted from birds to mosquitoes, and these in turn infect horses. The incubation period of the disease – that is, the time from infection until clinical signs appear – is 5 to 14 days.

The samples they take for the laboratory are from those horses that have died at the moment. and they are carried out by the INTA of Castellar and the National University of Córdoba. However, the other category of suspects that are not confirmed by laboratory, but by clinical symptoms, are increasing.

Hay two suspected cases that had the same symptoms as those in the Rio Negro capital and are found in Belisle and Valle Azul. At the moment it was not confirmed, since the samples were sent.

Suspected cases are added in Río Negro and the figure is expected to increase. We will have to wait for the official data.

Symptoms begin to be detected when horses present a neurological condition with different signs, such as wandering, hyperexcitation, depression, hyperthermia and recumbency mainly.
