The U.S. Centers for Disease Control and Prevention (CDC) has been monitoring the ongoing outbreak of the avian influenza A (H5N1) virus. This is widespread globally in wild birds, and has led to sporadic outbreaks in poultry, cows, several species of wild animals, and has been detected in exposed humans. The CDC recently sequenced the H5N1 virus in two respiratory specimens collected from a U.S. patient who was severely ill and has now died (PQ809549-PQ809564).  

As previously announced, the GenBank sequences, annotations, and metadata including from this patient are available through NLM’s NCBI resources.
