In the cattle disease LSDV, what does LS stand for?

• A. Localized swelling
• B. Lumpy skin
• C. Large spots
• D. Livestock syndrome

Answer: (B)

The main idea here is understanding how disease names form acronyms from the clinical signs they describe. In LSDV, the LS part comes from “Lumpy Skin,” naming the characteristic nodular lesions that give the disease its identity. So LS stands for Lumpy Skin. The full virus name, Lumpy Skin Disease Virus, reflects that Lumpy Skin describes the key clinical feature, with Disease and Virus as the other components.

Think of it this way: the nodules on cattle are firm lumps on the skin, which is why the term “lumpy” is used. Other options don’t fit because they either don’t capture the distinctive nodular skin signs or are too vague to be used as the disease’s name. For context, LSDV is a capripoxvirus that causes fever, nodules on the skin, and sometimes enlarged lymph nodes, typically transmitted by biting insects.
