Which statement best describes the current global status of classical swine fever in domesticated pigs?

• A. This disease is still common in many countries, but it has been eradicated from U.S., Canada, New Zealand, Australia, and most of Europe.
• B. Canada, New Zealand, Australia and Asia
• C. Canada, Mexico, and Haiti, as well as Europe and Asia
• D. This disease has really been eradicated from most of the world but it is still present in Haiti and Central America, close to the US

Answer: (A)

Classical swine fever (hog cholera) shows a mixed global picture: many high-income regions have eliminated the disease, while it remains present in numerous countries elsewhere. This means the United States, Canada, New Zealand, Australia, and most of Europe are CSF-free thanks to stringent surveillance, biosecurity, and control measures. Yet in many parts of Asia, Africa, and Latin America, the disease persists in pig populations, with ongoing outbreaks or enzootic transmission. So the statement that best describes the current global status is that the disease has been eradicated in the major developed regions listed, but it is still common in numerous other countries around the world. The other options either misstate where CSF remains or claim eradication more broadly than reality.
