What is the characteristic fever pattern of horses affected by African horse sickness?

African horse sickness typically presents with a fever that lasts several days and shows a clear daily cycle, rising in the afternoon and easing by the morning. This diurnal pattern, usually described as morning remission with afternoon exacerbation, generally spans about 3 to 8 days. That combination—duration of fever plus the pronounced daily fluctuation—distinguishes it from a fever that is only 1–2 days long, a continuous fever with no remission, or no fever at all.
