The mechanism for the development of the diseaseContained in care products and manure. During regeneration of damaged skin and mucous membrane, fallen pox crusts are a resistant pathogenic source of the pathogen.
How sheep and goat pox is transmitted can be observed when studying the ways of transmission of the virus.
Classification of methods of transmission of the virus:
- through the gastrointestinal tract;
- is transmissive;
The mode of transmission will determine the further development of the disease.
Transmissible route of infection - transmission of the virus by blood-sucking insects. In rare cases, it is transmitted colostrally( with milk) or in utero( through the placenta).
The last two types of transmission of sheep pox and goats do not play a large role in the spread of the disease.

Rapid transmission of the pathogen is possible while keeping infected and healthy animals. This type of transmission is the most common. Its contagiosity is 70-80% among other methods of transmission of the virus.
When transmitting sheep pox and goats by airborne droplets( respiratory), septic phenomena occur and the disease passes in a generalized form.
If a disease is suspected, immediately section healthy and infected animals.
The sheep pox and goat virus causes smallpox exanthema to form skin and mucous membranes. For the smallpox process is characterized by staged development. There are stages:
- is cool;
When studying the clinical picture, pay attention to the loss of the third and fourth stages. A characteristic feature of the manifestation of symptoms in sheep and goats in smallpox is the transition of the papules immediately into a crust( crust).
Smallpox infection of the small cattle is benign. The skin of the udder is affected, and in a young goat herd a lesion of the nasal and oral mucosa is recorded.
Distinguish between forms of the disease:
For the diagnosis of smallpox, the results of a clinical study are sufficient, given the infectious situation in the region.
Differential( comparative) diagnosis involves the elimination of scabies and scab in sheep, non-infectious eczema. FMD and ecthyma of contagious origin are excluded from goats.
Properly diagnosed, you can take the right measures to stop the nidus.
There are no methods for specific therapy. Sick sheep and goats are transferred to separate premises. They should be dry and warm. Feed light nutritious food. Some potassium iodide is added to drinking water. Apply antibacterial drugs to avoid the development of secondary microflora. The transfer of the disease contributes to the acquisition of active lifelong immunity.

Prevention should include the organization and conduct of routine preventive vaccination of livestock of sheep and goats to create passive specific immunity.
For the prevention of sheep pox and goats, it is necessary to systematically conduct veterinary and sanitary measures. When smallpox is detected, a quarantine regime should be introduced for new animals.
Violation of the quarantine regime provokes the emergence of new natural foci of viral infection.
The patient housing sites are regularly disinfected with bleach solution containing at least 5% active chlorine or sodium alkali. In order to prevent the spread of smallpox infection, pathological material( corpses of small ruminant cattle) is neutralized by burning.
The use of wool, leather in case of sheep and goats for industrial purposes is prohibited!
Milk after pasteurization is used without restrictions.
Lightning-fast spread of sheep pox and goats contributes to accuracy in keeping and eating disorders. Timely quarantine measures provide an opportunity to improve the herd from smallpox epizootics as soon as possible.
