Lumpy skin disease (LSD) is a poxviral disease with significant morbidity in cattle. Although the mortality rate is generally low, economic losses result from loss of condition, decreased milk production, abortions, infertility and damaged hides. The causative virus seems to be spread mainly by blood-feeding insects, such as certain species of flies and mosquitoes or ticks, and outbreaks can be widespread and difficult to control.
Lumpy skin disease virus (LSDV) is a member of the genus Capripoxvirus and the family Poxviridae. It is closely related antigenically to sheeppox virus and goatpox virus. Although these three viruses are considered to be distinct viral species, they cannot be distinguished by routine serological tests.
There is no evidence that LSDV can infect humans.
LSD was first reported in Asia and the Pacific region in 2019 in north-west China, Bangladesh and India. During the northern summer of 2020, LSD has continued its spread across continental Asia with many members in south and south east Asia confirming outbreaks.
LSD is currently endemic in most of Africa, parts of the Middle East and Turkey. Since 2015, the disease has spread to most of the Balkan countries, the Caucasus and the Russian Federation, where the disease continues to spread, making the risk of an imminent incursion into other unaffected countries very high. Since 2019, several outbreaks of LSD have been reported by Members in Asia.
Recently reported LSD outbreaks in our region include:
