Foot and mouth disease is a viral infection circulating among wild and domestic artiodactyl animals. Outbreaks of this disease are recorded in all countries of the world. The most susceptible to foot and mouth disease are domestic animals such as deer, cows, pigs, sheep and goats. Among wild animals, foot and mouth disease can affect roe deer, saigas, moose, bison, deer, wild boars, antelopes and other artiodactyls. Mortality of animals from foot and mouth disease is quite high.
Foot and mouth disease, animal viral infection, description, symptoms, first aid and treatment methods for foot and mouth disease, prevention.
Currently, the main role in the circulation of the virus is played by domestic animals. Wild animals become infected from them in common pastures and watering places. The occurrence of foot-and-mouth disease epizootics among wild ungulates is usually observed during outbreaks of this disease in domestic animals..
processing. Skins of prey animals are disinfected.
You can distinguish a sick animal from a healthy one by the presence of characteristic blisters filled with lymphatic fluid on the mucous membrane of the oral cavity and wings of the nose, as well as on the nipples of the udder and on the thin non-keratinized skin of hooves in artiodactyls.
At autopsy of animals that died from foot and mouth disease, they show exhaustion, sores on the gums and surfaces of the lips, gangrenous pneumonia, and degeneration of the heart. Stripes are visible on it – a symptom of a tiger heart. Sometimes purulent foci are found in the cortical layer of the kidneys. In some animals, rejection of the mucous membrane of the rumen and abomasum is noted.
Foot and mouth disease, the course and stages of the disease in humans, prevention.
For humans, foot and mouth disease is less dangerous. For 1.5 million diseases in animals, only one case of the disease in humans is recorded. A person can become infected through drinking raw cow and goat milk, meat and in the contact way when skinning, and through damaged skin when caring for sick animals.
Foot and mouth disease in a person begins with severe chills and headache 3-8 days after infection. High temperature lasts several days. Purulent vesicles appear in the mouth. Abundant salivation is noted. After 10-15 days, the patient usually recovers. A sick person is not dangerous to others.
Measures of non-specific prophylaxis of foot and mouth disease are the same as with other infections transmitted by contact and food. The meat of the shot sick animals is suitable for food after prolonged heat treatment. In fresh meat, the virus remains viable for two days, and in frozen meat for more than a month.
It should be remembered that foot and mouth disease virus can remain viable in animal skins for up to 28 days. However, acids and disinfectants quickly kill the virus. Therefore, the skins of suspicious foot-and-mouth disease or sick animals must be disinfected. The corpses of wild animals killed by foot and mouth disease are burned.
