Lumpy Skin Disease(LSD) Current Situation & Prevention Measures in Chinese Taipei July 17th, 2020 1 CONTENT Introduction Current situation in Kinmen Island Diagnosis Control measures 2 Introduction-1 LSD is a Type A infectious animal disease in Taiwan. LSD is a disease of cattle infected by the capripoxvirus and characterized by fever exceeding 41°C, 2–5 cm in diameter nodules on the skin, mucous membranes (vesicles, erosions, ulcers) and sometimes death. The susceptible animals include the domestic cattle and Asian water buffalo. 3 Introduction-2 According to the OIE Terrestrial Manual, the incubation period is 28 days. It is NOT zoonotic. Transmission of LSD virus (LSDV) is thought to be predominantly by arthropods, even certain species of biting flies and mosquitoes, or ticks acting the role, natural contact transmission in the absence of vectors. 4 Location of Kinmen China Kinmen Taiwan 315 kilometers between Taiwan and Kinmen on the Taiwan Straits 5 Current situation in Kinmen The total number of cattle farms is 594, raising about 6,200 cattle. The Livestock Research Institute (LRI) of Kinmen is the first confirmation of LSD incident Cattle farm. There are 548 cattle. The total number of 74 cattle in the same pen has been culled which include 23 confirmed cases and another remaining 51 cattle. After onsite inspection at other 593 cattle farms, 40 farms are suspected of being infected with LSD, and there are 168 suspected cattle that will be culled. 6 Infected Cattle 7 Location of the Livestock Research Institute (LRI) of Kinmen 8 Suspected Cases-1 15 July 2020 Township Farms Cattle Suspected Note Jinhu Township 16 657 40 Jinning Township 12 221 52 Jinsha Township 5 55 6 Jincheng Township 7 337 70 Total 40 1,270 168 9 Suspected Cases-2 Jinsha Township Jinning Township Jinhu LRI Township Jincheng Township 10 Diagnosis-1 Clinical diagnosis 11 Diagnosis-2 According to OIE Manual of Diagnostic Tests and Vaccines for Terrestrial Animals 2019 Chapter 3.4.12. Lumpy skin disease PCR & qPCR PCR qPCR 12 Diagnosis-3 The virus strain in cattle farm of Kinmen island was subjected to PCR and sequencing targeted on DNA dependent RNA polymerase subunit gene (RP030). Preliminary genetic and phylogentic analyses of the genomic sequence showed that the virus shared 100% nucleotide identity with the strains found in Xinjiang province of China in 2019. Also, an identity of about 98.5%~99.3% with the strains in sheep pox virus and goat pox virus was obtained. 13 Diagnosis-4 14 Diagnosis-5 Histopathology TEM 15 Control measures-1 In Kinmen, prohibit the live cattle to Taiwan following the FMD control measures, prohibit the carcasses and fresh meat of cattle to Taiwan since 10 July, implement the movement control for all cattle, continued inspecting the cattle farms, quarantine suspected cattle, disinfect and pest control, kill and dispose of infected cattle in a timely manner. Invite the experts of veterinary and entomology to discuss the preventive measures to reduce the risk of spreading.
