Horsepox is caused by HPXV and is characterized by mouth and skin eruptions HXPV isolate from the 1976 outbreak later sequenced Modern vaccinia virus smallpox vaccines are associated with cardiotoxicity; may have acquired undesirable properties not present in an ancestral virus (likely HPXV) Horsepox has potential for slower proliferation or decreased toxicity
