• A. Infectious disease
• B. Non-communicable disease
• C. Communicable disease
• D. Emerging disease

Answer: (C)

The idea here is how a disease passes between hosts and how we label that spread. African horse sickness is caused by a virus and is transmitted from horse to horse through the bite of infected Culicoides midges. Because the illness can move between animals via this vector, it fits the definition of a communicable disease. It’s not non-communicable since there is a mechanism for transmission between individuals. It’s also not an emerging disease, as it’s a well-known, established disease in certain regions rather than a newly appearing one.
