Quang Ngai province in Vietnam is grappling with a severe outbreak of dermatomyositis (VDNC) in cattle, affecting around 15,000 animals and resulting in a loss of 15 billion dong. The disease has spread across 13 out of 13 districts, towns, and cities, prompting the Department of Agriculture and Rural Development to implement prevention and control measures to prevent further spread. Nghia Hanh district, in particular, has seen significant impact with over 1,900 cases leading to 49 deaths. The cause of the outbreak is a virus spread by blood-sucking insects, notably the 'Stomoxys calcitrans' fly. The Department of Agriculture and Rural Development is advising authorities to take steps such as public notification, isolation of sick cows, and vaccination to contain the spread of the disease.
