Lumpy skin disease is a infectious disease that affects cattle caused by a virus of the family Poxviridae, genus Capripoxvirus (sharing the same genus with the virus that causes Chickenpox in goats and sheep).
In 1929, the disease was first discovered in Zambia.
October 2020 in Lang Son province, Vietnam.
The incubation period is about 4-14 days.
The disease spreads very quickly with the mortality rate of about 1-5%.
Does not affect humans.
Transmission: through placenta, semen, arthropods, transport, direct contact.
Infected cattle: Significant decrease in milk production and fertility, miscarriage, skin lesions, weight loss, reduced meat quality, mortality.
Lumpy skin disease (LSD) is caused by Lumpy skin disease virus (LSDV), a virus of the family Poxviridae, genus Capripoxvirus.
– Specimen: Skin nodules, scales, and scabs contain a relatively large number of LSD viruses. Viruses separated from this specimen can survive for up to 35 days and even longer.
– Blood :The LSD viruses can be separated from blood, saliva, eye and nasal secretions, and semen.
⇒ LSD viruses are found in the blood intermittently from about 7 to 21 days after infection and at a lower concentration than those in skin nodules
⇒ Cattle recover well with good nursery and care.
