Causes of dermatomyositis
Dermatitis nodules are an infectious disease that only affects buffalo and cows, but not humans and other animals. The disease entered our country in early October 2020, and then spread to many provinces and cities across the country.
The first outbreak of skin diseases in buffalo and cows occurred in Khanh Hoa in July 2021 in Khanh Binh township, Khanh Vinh district, according to the provincial sub-department of animal husbandry and veterinary medicine. After that, the disease spread to 8 counties and cities and affected nearly 1,200 cows.

Convenient transportation of buffalo and cows from other places. In addition, extreme weather has reduced the resistance of livestock, which creates favorable conditions for the development and spread of pathogens.
In addition, dermatomyositis is very contagious as it is spread through a wide range of transmission through insect bites such as flies, mosquitoes, ticks and blood-sucking seagulls. Meanwhile, people’s buffalo and cow grazing in the fields and common pastures is widespread.
In particular, conditions on livestock farms, especially in the region’s mountainous areas, are still limited, making it difficult to implement disease prevention measures.
In order to prevent skin infections in buffalo and cows, the Khanh Hoa Provincial Veterinary Bureau has instructed and recommended farmers to actively apply strict disease-proof breeding measures in the past. Only buy healthy buffalo and cows from reputable farms.
At the same time, fully vaccinated against dangerous diseases in buffalo and cows such as foot-and-mouth disease, dermatitis, pasteurellosis, cleaning and disinfection with specific chemicals to kill intermediate hosts such as ticks, seagulls, flies, mosquitoes, etc.

Our records with the family of Mr. Nguyen Bao An, a breeding cow breeder, in Van Tu Dong Village, Cam Hoa Township (Cam Lam), show that he is very conscious of disease prevention and control.
Mr. An said that his herd of cows is always close to 20 cows and sells 5-7 calves per year, valued at VND15-16 million/capita. Raising cows is the family’s main source of income, so he attaches great importance to cow health.
Therefore, he said that in addition to vaccination and environmental hygiene in the breeding area, regular spraying of insecticides will also have positive effects as the disease vectors will be destroyed.
