ABSTRACT
Lumpy skin disease (LSD) is a significant viral disease affecting cattle. Transmitted primarily by arthropod vectors, LSD has substantial economic impacts. LSD has become a major issue in Vietnam, with the first occurrence recorded in October 2020 in Lang Son province. In 2021, there were outbreaks of LSD in many regions, with Tien Giang province being the most severely affected. This research aims to analyze the epidemiological features of LSD, determine possible sources and related risk factors for an epidemic of LSD in Tien Giang. In 2023, the morbidity rate was 42.55% (20/47), and the death rate was 6.38% (3/47), leading to a case fatality rate of 15.0% (3/20). The primary clinical manifestations were cutaneous lesions, dyspnea, and lameness. The most impacted group was cattle under six months old. The investigation found indicators associated with disease outbreaks, including clinical symptoms in nearby farms, unvaccinated animals, and the absence of vector control measures. Given the significant economic repercussions caused by LSD, it is crucial to establish and enforce efficient control and prevention measures. These measures include animal movement regulation and isolation, adherence to biosecurity procedures during neighboring disease outbreaks, and focused immunization of vulnerable populations to halt disease transmission.
