On August 8, in the herd of cows of Mr. Dang Xuan Son's family in village 5, Dien Ky commune (Dien Chau), 1 calf showed symptoms of illness, stopped eating, had lumps and bumps all over its body, and could not walk. After only 1 day, the calf died. The veterinary agency took samples, destroyed them, and determined that they were infected.Lumpy skin disease.
The cause of this outbreak, according to the assessment of the Dien Chau District Agricultural Service Center, is that Dien Ky commune is an old lumpy skin disease outbreak since 2021, while 3 cows and calves of Mr. Dang Xuan Son's household have not been vaccinated against lumpy skin disease. Therefore, this is a re-epidemic point from the previous old outbreak. Dien Ky is a locality with a large herd of buffalo and cows with a total herd of 177; meanwhile, in Dien Chau district, there are many households trading, transporting, gathering, and slaughtering buffalo and cows, and in 2021, 31/37 communes had buffalo and cows with lumpy skin disease, 614 were sick, and 104 died.
At the same time, the spring vaccination rate for buffalo and cow herds in Dien Chau district was low. Therefore, the local government soon proposed to the Department of Animal Husbandry and Veterinary Medicine to support 125 doses of vaccine from the provincial source without charging for vaccination to surround the epidemic in Dien Ky commune, starting from August 19.
According to Mr. Le The Hieu - Head of the District Department of Agriculture and Rural DevelopmentDien Chausaid that currently the outbreak in Dien Ky commune has been controlled, there are no other outbreaks in the district. With the number ofVaccineThe province has just issued that, the district has directed the locality to organize vaccination for the buffaloes and cows that need to be vaccinated in village 5 and some neighboring villages. In addition to the provided vaccine source, it is necessary to propagate and mobilize livestock farmers to buy more vaccines to vaccinate 100% of the area that needs to be vaccinated. At the same time, solutions are implemented to spray disinfectants to disinfect barns to control the spread of the disease.

"The most effective solution to prevent lumpy skin disease in particular and diseases in general for livestock is vaccination. Therefore, localities need to have solutions and propaganda for farmers to achieve the highest vaccination rate" - Mr. Ngo Duc Quynh - Deputy Head of the Department of Animal Husbandry and Veterinary Medicine emphasized.
However, livestock farmers should not be subjective, because there is a high risk of outbreaks after the rainy season. Due to the development of insects: flies, mosquitoes, ticks, gnats... along with the carcasses and animal waste drifting along the water, leading to not only lumpy skin disease but also other infectious diseases. Therefore, the solution to prevent diseases in general for livestock is to promote vaccination; along with that,disinfectionregularly by sprinkling lime powder around the barn; farmers need to apply bio-safety farming to avoid pathogens from entering. When increasing the herd, farmers need to find and buy breeds of clear origin and free of disease. Daily feed for livestock and poultry needs to be processed and cooked, especially in some areas where farmers often use waste water from shops as feed for livestock. Especially, during the rainy season, in low-lying areas, farmers should proactively build high barns, or use materials that float easily such as barrels combined into floating rafts, to make shelter for livestock when flooded, along with preparing dry food for livestock. When cattle and buffaloes show the above symptoms, farmers need to report to local authorities to promptly find solutions to prevent and protect the livestock.
Symptoms of lumpy skin disease in cattle and buffaloes often include the following signs: High fever, possibly over 41°C, loss of appetite, weakness, emaciation; marked reduction in milk yield in lactating cattle; rhinitis, conjunctivitis and excessive salivation; swelling of the superficial lymph nodes; formation of nodules 2 - 5 cm in diameter, especially on the scalp, neck, legs, udders... within 48 hours of the onset of fever. These nodules are round, firm and raised above the skin, subcutaneous tissue and sometimes the underlying muscles. Large nodules may become necrotic and eventually fibrotic and persist for several months; leaving scars that may be permanent. Blisters, necrosis and ulcers may appear in the mucous membranes of the mouth and digestive tract as well as in the trachea and lungs. The legs and other abdominal parts of the body, such as the scrotum, breast, and scrotum, may secrete fluid, making the animal reluctant to move.
