Maedi-Visna translates to which two clinical features in sheep?

Maedi-Visna is named for its two main clinical manifestations in sheep: dyspnea from chronic interstitial pneumonia (maedi) and wasting (visna). The disease is a chronic lentiviral infection that progresses with lung damage causing breathlessness, and systemic wasting as the illness advances. Therefore, the two features reflected in the name are pneumonia-related breathing difficulty and weight loss. Other options describe symptoms not characteristically tied to this infection (such as fever, diarrhea, or a non-specific cough), so they don’t fit the typical presentation as well.
