African swine fever is contagiousdisease. It is characterized by fever, necrotic or inflammatory changes in the parenchymal organs. It is also characterized by hemorrhagic diathesis.
African swine fever: what is this disease
Its causative agent is a DNA-containing virus,which separated into an independent family. This virus is very resistant to low temperatures. It is also resistant to drying and rotting. The source of the infection are sick animals that have been carrying the virus for more than fifteen months. Most often, infection occurs through damaged mucous membranes, wounds on the skin, through meat, blood and so on. Sometimes the infection is carried by insects that come in contact with a sick (dead) animal.
In natural conditions, the African plague strikesand wild, and domestic pigs. The virus can lurk long in the body and not make itself felt. In general, the incubation period lasts from five to ten days. Most often the disease is very fast. Its main forms: acute, supra-acute, chronic, subacute, latent. The most common of these forms is acute and super-sharp.
For a hyperactive flow, a very highbody temperature of the animal. He has shortness of breath, death occurs within three days. African swine fever can cause death even without any clinical manifestations.
With an acute current, the temperature is also alwaysincreased. The condition of the animal becomes depressed: weakness, lack of appetite, drowsiness, paresis of the extremities, vomiting is possible, as well as diarrhea with blood. The latter is not particularly frequent, as in most cases, animals suffer from constipation. In this case, you can observe spots of violet, which are located on the snout, belly, neck, crotch. African plague in acute form may be accompanied by bronchitis. Before death, the temperature drops below normal. In most cases, the animal dies while in a coma.
The subacute course of the disease differs little from the acute symptom. It's just slower. The African plague can last up to twenty days in this case. The result is death.
In the chronic course of the disease is not so often. Some animals survive. Symptoms: delayed development, lag in growth, exhaustion of the body, arthritis and so on.
Latent flow does not have any specific clinical manifestations.
African swine fever: treatment and prevention
There is no treatment so far. Measures of prevention can be different. Do not allow contaminated meat to spread. To do this, there is veterinary supervision. Particular attention is paid to imported swine meat, which is imported from countries in which the outbreaks of this disease were once recorded.
When a pathogen is detected, all animals that arebelong to one or another household, they are placed in quarantine. In almost all cases, they are killed in a bloodless way. Bodies are burned - this is a mandatory rule. All farms that are in the neighborhood, must be tested.
When the infection spreads, all the pigs are cut out at a distance of ten kilometers square.
