Proactive Measures Against Lumpy Skin Disease

In a move to safeguard the cattle population, the Jeonnam Animal Sanitation Laboratory is ramping up its surveillance efforts against Lumpy Skin Disease (LSD).These enhanced measures include rigorous vaccine antibody monitoring, proactive virus detection on farms, and routine testing to confirm the absence of the virus. This initiative is especially timely, coinciding with the increase in insect activity during April, which are known vectors for the disease.

Enhanced Vaccine Antibody Monitoring

A key component of the strategy involves meticulously checking the immunity levels on smaller farms to assess vaccine effectiveness. Last year, the laboratory conducted 2,356 tests across 225 farms, repeated two to six months post-vaccination. This year, the program is considerably expanding to encompass 6,468 tests across 616 farms, demonstrating a commitment to complete monitoring.

According to recent data from the World Organisation for Animal Health (WOAH), effective vaccination campaigns are crucial in controlling the spread of LSD. The Jeonnam initiative aligns with these global best practices.

Targeted Virus Surveillance

The surveillance program is strategically divided into two categories: purpose forecast and statistical forecast, allowing for a targeted approach based on risk assessment.

Purpose Forecast: High and Medium-Risk Areas

The purpose forecast focuses on regions identified as high-risk (based on 2023-2024 data) and medium-risk (including the west coast and border areas of adjacent cities). During peak insect activity from April to november, approximately 3,180 farmers will be monitored. This proactive approach aims to identify and contain potential outbreaks before they escalate.

Statistical Forecast: Low-risk area Verification

Statistical forecasts are conducted year-round across 219 farms in lower-risk areas to confirm the continued absence of the virus. encouragingly, all 126 farms tested in Muan and Sinan last year returned negative results, highlighting the effectiveness of existing preventative measures.

Expert Opinion on Disease Prevention

Jung Ji-young, director of the Jeonnam-do Animal Sanitation Testing Director, emphasized the critical role of livestock farmers in preventing disease recurrence. Compliance with thorough defense rules is paramount, she stated, underscoring the importance of collaborative efforts in maintaining animal health.

Background: Lumpy Skin Disease in Korea

Since the initial outbreak of LSD in Seosan, Chungnam, on October 19, 2023, there have been 107 cases nationwide in 2023 and 24 cases in 2024. Jeonnam Province experienced two cases in 2023 (muan and Sinan) and three cases in 2024 (Yeongam, Yeosu, and goheung). Though,no new cases have been reported as then,indicating the success of containment efforts.

Lumpy Skin Disease is a viral disease affecting cattle, characterized by symptoms such as high fever and skin nodules. While typically not fatal, it can significantly impact livestock productivity and trade.

Jeonnam Intensifies Monitoring for Lumpy Skin Disease

In response to the ongoing threat of Lumpy Skin Disease (LSD), the Jeonnam Animal Hygiene Testing Center is implementing an enhanced surveillance program. Starting this April, the initiative focuses on rigorous antibody monitoring, early detection of viral infections on farms, and consistent pre-monitoring tests to confirm the absence of the virus. This proactive approach coincides with the seasonal increase in vector insect activity, which are known carriers of the disease.

Understanding Lumpy Skin Disease and its Transmission

Lumpy Skin Disease is a viral ailment affecting cattle, characterized by symptoms such as elevated fever and the development of skin nodules. The disease spreads primarily through blood-feeding insects like flies and mosquitoes. Vaccination campaigns are scheduled to align with the peak activity period of these vectors, aiming to bolster herd immunity.

Expanded Antibody Monitoring Program

The core of the surveillance strategy is the Lumpy Skin Disease vaccine antibody monitoring test. This test assesses the immunity levels within cattle farms, providing crucial data on vaccine effectiveness.Building on last year’s efforts, which involved testing 2,356 animals from 225 farms at two intervals (2-3 months and 6 months post-vaccination), the program is significantly expanding.This year,the target is to test 6,468 animals across 616 farms,ensuring a more comprehensive assessment of vaccine efficacy.

Strategic Farm Surveillance: Purposeful and Statistical Approaches

Farm surveillance is conducted through two distinct methods: purposeful surveillance and statistical surveillance. These approaches are designed to target diffrent risk levels and provide a comprehensive overview of the disease’s presence.

Purposeful Surveillance in High-Risk Areas

During the insect vector activity period (April to November), purposeful surveillance will target 3,180 animals from 636 farms. This targeted approach focuses on regions identified as high-risk (counties with reported cases in 2023-2024) and medium-risk (counties bordering the west coast and border areas where outbreaks occurred in 2023-2024). This proactive monitoring aims to quickly identify and contain any potential outbreaks.

Statistical Surveillance in Low-Risk Areas

Statistical surveillance is conducted year-round, examining 1,095 animals from 219 farms in other low-risk areas.This ongoing monitoring serves to verify the continued absence of the virus in these regions. Notably, last year, 126 animals from 12 farms within the outbreak areas of Muan and Sinan were tested, with all results returning negative.

Call to Action: farmer Cooperation is Crucial

Jeong Ji-yeong, director of the Jeonnam Animal Hygiene Testing Center, emphasizes the critical role of livestock farms in preventing the resurgence of Lumpy Skin Disease. Active reporting by livestock farms and strict compliance with quarantine rules are most important. The center is committed to early virus detection through continuous farm surveillance, but the success of these efforts hinges on the cooperation of farmers.

National and Regional Context of Lumpy Skin disease

The first reported case of Lumpy skin Disease in South Korea occurred in Seosan, South Chungcheong Province, on October 19, 2023. as then, there have been 107 cases nationwide in 2023 and 24 cases in 2024. In Jeonnam, the situation has been relatively contained, with no new cases reported as the initial outbreaks in 2023 (Muan and Sinan) and 2024 (Yeongam, Yeosu, and Goheung). The intensified surveillance efforts aim to maintain this positive trend and prevent future outbreaks.

According to recent data from the Ministry of Agriculture, Food and Rural Affairs (MAFRA), proactive vaccination and quarantine measures have been instrumental in controlling the spread of LSD across the country. Though, continued vigilance and adherence to biosecurity protocols remain essential to safeguard the livestock industry.
