Abstract BackgroundGlobally, livestock contributes about 40% of agricultural output sustaining livelihoods and food security of almost a billion people. In Uganda, livestock contributes 5.2% and 12.7% to the total national GDP and agricultural GDP, respectively. In districts like Namisindwa, diseases like Lumpy Skin Disease (LSD) affect the sector undermining its trade and production. Studies on the economic impact and risk factors have not been undertaken in such areas. This study thus sought to unravel information regarding economic impact and perceived risk factors associated with LSD in Namisindwa district. A cross sectional study involving quantitative approaches was employed in this study. Dependent variables were period prevalence and associated economic losses due effect of LSD on cattle herds while independent variable were potential factors influencing spread of the disease among cattle herds. The financial impact assessment was based on the farmers’ calendar year. Results The total economic losses incurred by farmers in Namisindwa district in a single outbreak of LSD was estimated at UGX 574,999,741 (USD 155,405). The most prominent economic loss due to LSD was attributed to low milk yield in lactating cattle as well as poor draught power performance. Other major contributions to economic losses due to LSD after the aforementioned two factors were cost of veterinary services and mortalities of cattle. Economic losses associated with loss of calves, and skin losses were perceived to be the lowest. Introduction of new animals, communal grazing and access to veterinary services were significantly associated with outbreaks of Lumpy Skin Disease. Specifically, farmers with access to veterinary services were less likely to be affected with the rampant spread of the LSD in their cattle, OR = .03361 and P-value < .05. Conclusion There is need for Ministry of Agriculture, Animal Industry and Fisheries in Uganda to advance interventions for prevention and control of LSD in the district. Larger scale and rigorous studies ought to be undertaken also to understand the risk factors and economic impact of LSD outbreaks.

The first outbreak of lumpy skin disease (LSD) in Thailand was reported in March 2021, but information on the epidemiological characteristics of the outbreak is very limited. The objectives of this study were to describe the epidemiological features of LSD outbreaks and to identify the outbreak spatio-temporal clusters. The LSD-affected farms located in Roi Et province were investigated by veterinary authorities under the outbreak response program. A designed questionnaire was used to obtain the data. Space-time permutation (STP) and Poisson space-time (Poisson ST) models were used to detect areas of high LSD incidence. The authorities identified 293 LSD outbreak farms located in four different districts during the period of March and the first week of April 2021. The overall morbidity and mortality of the affected cattle were 40.5 and 1.2%, respectively. The STP defined seven statistically significant clusters whereas only one cluster was identified by the Poisson ST model. Most of the clusters (n = 6) from the STP had a radius &lt;7 km, and the number of LSD cases in those clusters varied in range of 3–51. On the other hand, the most likely cluster from the Poisson ST included LSD cases (n = 361) from 198 cattle farms with a radius of 17.07 km. This is the first report to provide an epidemiological overview and determine spatio-temporal clusters of the first LSD outbreak in cattle farms in Thailand. The findings from this study may serve as a baseline information for future epidemiological studies and support authorities to establish effective control programs for LSD in Thailand.

Lumpy skin disease (LSD) is an economically important, arthropod borne viral disease of cattle. Vaccination by the live attenuated homologous Neethling vaccine was shown as the most efficient measure for controlling LSD. However, adverse effects due to vaccination were never quantified in a controlled field study. The aim of this study was to quantify the milk production loss and mortality due to vaccination against LSD. Daily milk production, as well as culling and mortality, were retrieved for 21,844 cows accommodated in 77 dairy cattle farms in Israel. Adjusted milk production was calculated for each day during the 30 days post vaccination. This was compared to the preceding month by fitting mixed effects linear models. Culling and mortality rates were compared between the 60 days periods prior and post vaccination, by survival analysis. The results of the models indicate no significant change in milk production during the 30 days post vaccination period. No difference was observed between the pre- and post-vaccination periods in routine culling, as well as in immediate culling and in-farm mortality. We conclude that adverse effects due to Neethling vaccination are negligible.

SUMMARYA cross-sectional study based on a questionnaire survey was conducted to determine the distribution of lumpy skin disease (LSD) and associated risk factors in three main agro-climatic zones of Ethiopia. A total of 330 questionnaire surveys were collected from 44 peasant associations (PA) distributed in 15 districts. Across agro-climate zones, herd-level LSD prevalence in the midland agro-climate was significantly higher 55·2% [95% confidence interval (CI) 47·5–62·6] than in highland and lowland agro-climate zones. Overall observed LSD prevalence at animal-level was 8·1% (95% CI 7·3–8·9) and observed mortality was 2·12% (95% CI 1·73–2·6). The odds ratio (OR) of LSD occurrence in midland vs. highland and lowland vs. highland zones was 3·86 (95% CI 2·61–5·11) and 4·85 (95% CI 2·59–7·1), respectively. Significantly high risk of LSD occurrence was associated with communal grazing and watering management (OR 4·1, 95% CI 2·02–6·18) and introduction of new cattle (OR 8·5, 95% CI 6·0–11·0). Our findings describe the distribution of LSD in different agro-climates in Ethiopia along with associated risk factors, and can help shed light on the epidemiology of LSD in other African countries suffering from the disease.

Potential Risk Factors

Lumpy skin disease (LSD) is caused by the virus of the same name and has major economic impacts on cattle breeding. In Turkey, frequent cases of cattle LSD have been reported over the last years. The present study aimed to analyze potential risk factors for LSD and provide information for controlling the spread of infectious diseases by a geographic information system (GIS). The research included cross-sectional and retrospective studies with active disease follow-up and semi-structured interviews (SSI) from August 2013 to December 2014 in Turkey. Potential risk factors for LSD were evaluated based on environmental conditions and provincial demographic and epidemiological data. Of the total of 562 observed animals, 27.22% and 2.67% of cattle were sick and died due to LSD, respectively. The morbidity rate was 26.04% in mixed and 38.18% in local breeds. The animal-level prevalence significantly differed among animals of different age, sex, and with different vaccination status (P<0.05). It was more serious in younger animals and females and during drier weather conditions. A trend of seasonality was observed in LSD occurrence. Significant risk factors affecting the prevalence of LSD were proximity to the southern border of Turkey, animal movements, and animal markets. In this process, geographical query, analysis, and thematic map production were performed by GIS.
