With reports of the first human death from bird flu in the US, some Americans are feeling an uncomfortable flashback to the early days of Covid-19, when infectious disease experts were talking about a new virus that was sending people to the hospital with respiratory infections.

The U.S. reported its first human death from H5N1 bird flu, marking a significant milestone in the outbreak. The patient was over 65 with underlying health conditions and was hospitalized in Louisiana in December.

The patient was infected after contact with domestic and wild birds, specifically a non-commercial backyard flock and wild birds he raised at home.
