Cattle plague was a lethal disease of bovines cause by the rinderpest virus, an agent closely related to measles. It came to Britain from Europe in the mid 1860s and killed at least 420,000 cows. Rinderpest is not a coronavirus. Its R number is probably three times greater than that of Covid-19, and its mortality rate is much higher. But as a model it still has relevance to contemporary events.
