Which characterization describes the pulmonary form of AHS in terms of incubation, clinical signs, and mortality?

The pulmonary form of African horse sickness is the most fulminant and is defined by a very rapid course after infection. After a short incubation of about 3 to 5 days, horses develop fever, loss of appetite, depression, a noticeable cough, and increasing difficulty breathing (dyspnea) as lung involvement progresses. This form carries an extremely high mortality, typically exceeding 95%, with death often occurring within 4 to 5 days after signs begin. This combination of a brief incubation, prominent respiratory distress, and almost universally fatal outcome is what makes this description the best fit for the pulmonary form.
