Lumpy Skin Disease (LSD) in Turkish cattle appeared suddenly two years ago. This study evaluates potential risks of LSD and recommends appropriate control measures. The World Animal Health Organization’s protocol was used for the risk analysis. Likelihoods for disease release and exposure were estimated with a qualitative scale ranging from negligible to high. Outbreaks were recorded in nine provinces in Turkey. Total economic loss due to the disease was estimated to be $241.903.500 US dollars. The risk analysis suggests a greater than negligible risk. Therefore, disease prevention and control strategies should be considered by the Turkish Veterinary Authority.

Successful Control

This article reviews some of the important aspects of lumpy skin disease (LSD) that may impact on its successful control. A resurgence of the disease in the last decade has highlighted some constraints of the Neethling strain vaccine, but there is no evidence of vaccine breakdowns owing to the presence of heterologous field strains. More research is needed on epidemiology and transmission of LSD in South Africa to formulate control measures.

SUMMARYLumpy skin disease virus (LSDV) is of high economic importance and has spread rapidly to many European and Asian countries in recent years. LSDVs spread to China in 2019 and have caused severe outbreaks in multiple provinces. The LSDVs in China have not been well investigated. Here we isolated an LSDV (GD01/2020) in southeast China and investigated its features in replication, phylogenetics, and genomics. GD01/2020 caused a typical LSD outbreak and replicated well in MDBK cells as detected by a novel quantitative real-time PCR assay targeting the viral GPCR gene. GD01/2020 was similar in phylogenetics to the one circulating in Xinjiang, China in 2019, and distinct from the LSDVs identified in other countries. In genomics, GD01/2020 was a vaccine-recombinant similar to those identified in Russia. A total of 13 major putative recombination events between a vaccine strain and a field strain were identified in the genome of GD01/2020, which could affect the virulence and transmissibility of the virus. The results suggested that the LSD outbreaks in China caused by a virulent vaccine-recombinant LSDV from the same unknown exotic source, and virulent vaccine-recombinant LSDVs obtained transboundary transmissibility. This report shed novel insights into the diagnosis, transmission, and control of the disease.

AbstractLumpy skin disease virus (LSDV), a poxvirus that causes severe disease in cattle, has in the last few years rapidly extended its distribution from Africa and the Middle East into Europe, Russia, and across Asia. LSDV is believed to be primarily spread mechanically by blood-feeding arthropods, however the exact mode of arthropod transmission, the relative ability of different arthropod species to acquire and retain the virus, as well as their comparative importance for LSDV transmission, remain poorly characterised. Since the vector-borne nature of LSDV transmission is believed to have enabled the rapid geographic expansion of this virus, the lack of quantitative evidence on LSDV transmission has impeded effective control of the disease during the current epidemic. Obtaining high quality data on virus transmission by arthropods is challenging, and practical limitations often result in inadequate arthropod numbers or model hosts, limiting the transferability of experimental findings to the natural transmission scenario.We have addressed these limitations in this study. Using a highly representative bovine experimental model of lumpy skin disease we allowed four representative vector species (Aedes aegypti, Culex quinquefasciatus, Stomoxys calcitrans and Culicoides nubeculosus) to blood-feed on LSDV-inoculated cattle in order to examine the acquisition and retention of LSDV by these species in unprecedented detail. We found the probability of LSDV transmission from clinical cattle to vector correlated with disease severity. Subclinical disease was more common than clinical disease in the inoculated cattle, however the probability of vectors acquiring LSDV from subclinical animals was very low.All four potential vector species studied had a similar rate of acquisition of LSDV after feeding on the host, but Aedes aegypti and Stomoxys calcitrans retained the virus for a longer time, up to 8 days. There was no evidence of virus replication in the vector, consistent with mechanical rather than biological transmission. The parameters obtained in the in-vivo transmission experiments subsequently enabled enhanced modelling approaches to determine the basic reproduction number of LSDV in cattle mediated by each of the insect species. This was highest for Stomoxys calcitrans (19.1), C. nubeculosus (7.4), and Ae. aegypti (2.4), surprisingly indicating these three species are all potentially efficient transmitters of LSDV. These results reveal that currently applied LSDV control measures such as stamping out of all cattle on affected premises or insect control measures targeting single species need to be urgently reconsidered. Overall our studies have highlighted that the combination of highly relevant in-vivo experiments and mathematical modelling can be directly applied to devise evidence-based proportionate and targeted control programmes.

Lumpy skin disease (LSD) is an emerging transboundary viral disease of cattle originating from the African continent. Here we describe the first LSD outbreak reported in the Republic of Kazakhstan, in July 2016. Initially, LSD was reported in a cattle farm located 49 km from Kazakh –Russian border in, Atyrau Oblast in West Kazakhstan. Subsequently, the disease spread to neighbouring farms situated within the same district. Following a preliminary investigation, the local State Veterinary Service declared a strict quarantine according to the State Contingency Plan, along with immediate total stamping out and cattle movement restrictions. During the outbreak, the number of affected cattle within an epidemiological unit reached 459 cattle out of registered 3557 susceptible cattle with 12.90% morbidity and 0.96%, mortality. This manuscript presents the epidemiological situation, the diagnosis, the control measures including mass vaccination and the stamping out campaign.s
