How to spot and treat lumpy skin disease in your herd

Animal with Lumpy Skin Disease.

In a chief baraza recently, a vet said our village was facing a risk of Lumpy Skin Disease due to movement of livestock and the fact that a neighbouring sub-county had reported the disease. He advised us to vaccinate our cattle and avoid buying cattle from the said sub-county until the disease is fully contained. I am ready to vaccinate my cattle and I hope my neighbours will do the same. How affordable is the vaccine and apart from this, is there any other way to prevent or control this disease?

Also, what are the clinical signs of this disease?
