A Detailed Explanation of the Symptoms and Control Methods of Sheep Pox

Sheep pox, also called sheep smallpox, is an acute, febrile, contagious infectious disease of sheep caused by the sheep pox virus. In severe cases, this disease may be transmitted to humans and is extremely harmful. So what are the symptoms of sheep pox? How is it prevented and controlled?

1. What are the symptoms of sheep pox?

There are many causes of sheep pox, commonly including improper feeding and management, seasonal factors, vaccine factors, parasite factors, and human factors. Improper feeding is often due to poor hygiene in the sheep shed, high stocking density, and failure to clean manure in time, which leads to bacterial growth and disease onset; and after the disease occurs, if sick sheep are not isolated in time, the disease spreads rapidly. Seasonal factors refer to the fact that the sheep pox virus has strong resistance to dryness and cold, so it begins to be active and reproduce in winter and early spring. Vaccine factors refer to the fact that farms usually inject sheep with vaccines to prevent sheep pox, but if the vaccine is stored improperly, it may become ineffective and thus lead to infection with this disease; the vaccine should be stored in a low-temperature environment below 0 degrees. Parasite factors refer to the fact that certain parasites can carry the sheep pox virus, and if deworming is not carried out in time, the resistance of sheep is weakened and they are more susceptible to this disease. Human factors are related to vaccine factors; if disinfection is not carried out as required during injection, or if the injection site and method are improper, the vaccine may also become ineffective and cause sheep to become infected with this disease.

The sheep pox virus incubates on sick sheep for about one week. When the disease occurs, the body temperature of sick sheep rises significantly, reaching 41-42 degrees, and they show listlessness, accelerated heartbeat and breathing, reduced appetite or refusal to eat, reduced activity, or standing still with an arched back. Tears flow from the corners of the eyes, after which purulent secretions gradually begin to flow from the eyes and nose. After ewes become ill, milk production decreases or stops. Some sheep have a slight cough after the disease begins, and papules begin to appear on the body surface and gradually become blisters; finally the blisters rupture and large brown scabs appear. This disease spreads extremely quickly, and its course is about half a month. In severe cases, death can occur within two to three weeks. Pregnant ewes may abort or have stillbirths after becoming ill, and the mortality rate of lambs after becoming ill is extremely high.

2. How is sheep pox prevented and controlled?

Feeding management should be strengthened, and introducing sheep breeds from epidemic areas should be avoided. When introducing new sheep, they must first be isolated and observed, and epidemic prevention measures must be taken before they are put into the flock for rearing. Normally, do a good job of hygiene and disinfection in the sheep shed to reduce pathogens, and regularly vaccinate the flock. When vaccinating, the vaccination procedure must be strictly followed. After disease is found, sick sheep should be isolated in time, and then after comprehensive disinfection of the sheep shed, the pox rash areas of sick sheep should be washed with a 1% saline solution or 0.1% potassium permanganate, and then coated with iodine glycerin or a mixture composed of propolis, alcohol, and Yunnan Baiyao, 2-3 times a day. If ulceration occurs, medicine can be injected intramuscularly, and when the condition is relatively severe, intravenous injection of 500 ml of 5% glucose solution can be used, with excellent results.
