This document is in Spanish. "Avian flu is a viral disease and it can be very contagious and even deadly in poultry (e.g., chickens). Of great concern are the highly pathogenic avian influenza (HPAI) H5N1 viruses that have killed millions of birds and have infected humans in other countries. If these viruses are found in the U.S., take appropriate precautions if you are involved in poultry destruction." This document also includes "Cuando se Trabaja en Actividades de Erradicación".
