Multiple Choice

Which description matches the fever form of AHS in terms of incubation, signs, and outcome?

The fever form represents the mildest end of African horse sickness. After infection, incubation can be up to about two weeks, and affected horses show only a low-grade fever with minimal clinical signs, not the severe edema or respiratory distress seen in the more serious forms. Because the virus replication is limited and the horse’s immune response can control it, the outcome is typically recovery rather than death. This is why describing a mild to subclinical illness with an incubation up to 14 days, a low-grade fever, and recovery fits best. The other options describe more severe, rapidly fatal, or high-mortality scenarios that are not characteristic of the fever form.
