Rabbit viral hemorrhagic disease, commonly known as rabbit plague, is an acute, highly contagious disease caused by rabbit hemorrhagic disease virus (RHDV). Since its first discovery in Wuxi, Jiangsu, China in 1984, it has rapidly spread to most parts of China. The rapid spread of the disease can cause more than 90% of young rabbits to die, often devastating the rabbit farm. This spring, an outbreak occurred in a rabbit farm. The author immediately adopted a series of emergency prevention and treatment measures and received good results. It is summarized as follows: 1 Clinical manifestations and diagnosis At the beginning of the disease, the breeder found that 3 rabbits in the rabbit house suddenly died. There was no obvious lesion in the necropsy. Later, more than 10 adult rabbits died one after another. The death was dominated by young rabbits. Before the death, they were briefly excited and screamed. They died quickly. In some rabbits, foamy blood or bloody stools flow out of the nasal cavity, and some show convulsions. After death, they show angulations. Necropsy: poor blood coagulation. The mucous membranes of the larynx and trachea are highly congested with scattered bleeding. The lungs are dark red, swollen, and bleeding. The liver is swollen, firm, crispy and fragile, purple-red, with necrotic lesions from the tip to the size of the rice, or fused into flakes. The spleen is swollen with blood and dark purple, and it is easily scratched. The kidneys are swollen with purple-black color, and the boundaries between the cortex and medulla are distinct, with bleeding points and necrotic lesions. Gastrointestinal bleeding, some dead rabbit pericardial effusion, ovarian type of bleeding. Rabbits were diagnosed as having viral haemorrhage by epidemiology, clinical manifestations, and necropsy. For further diagnosis, a laboratory diagnosis was made and the diagnosis of RHDV infection was confirmed. 2 Take emergency measures 2.1 Strictly isolate the rabbit farm and stop all contact with the outside world to prevent the spread of the disease to other places. 2.2 Emergency inoculation with rabbit inactivated vaccine, 1 to 3 kg of rabbits were injected subcutaneously at 1 m1 each; 3 kg or more were injected subcutaneously at 1.5 ml each. 2.3 Rabbit house rabbits were spray-disinfected with 1.5% hydrogen peroxide at 20ml aerosol per cubic meter, and rabbithouses were sterilized with sodium hypochlorite at least 3 times per day to cut off the route of infection. 2.4 Strengthen feeding and management, adding 0.1% sulfamethazine to the feed to prevent secondary infection. 2.5 Incineration of dead rabbits, utensils and work clothes are all disinfected with cleaning and disinfectants to eliminate the source of infection. 3 Conclusion After a week of emergency prevention and control work, rabbit viral haemorrhagic disease was controlled and the rabbit population recovered from calm and normalized after 10 days. The death of the disease was clearly manifested mainly in adult rabbits. Five days after the emergency injection of the vaccine, the number of deaths dropped sharply and was controlled after seven days. The performance of the vaccine has already produced strong immunity in five to seven days. The cumulative number of deaths during the onset accounted for about 10% of the population of rabbits. Explain that this control measure is effective. At the same time, the author believes that, in addition to measures such as isolation and blockade and emergency vaccination, the repeated disinfection of rabbit houses with hydrogen peroxide is also one of the comprehensive measures to combat the disease.
