Figure 1. — Cumulative global cases and deaths of human infections with H5N1, H7N9, and H9N2 avian influenza viruses reported to the World Health Organization (WHO). Cases and deaths are cumulative from the first reported case of each virus subtype in humans until February 22, 2024. Numbers on top of the bars indicate how many cases and deaths have been reported to the WHO. Note: as of February 22, 2024, two deaths have been reported from H9N2 infections according to the WHO. Due to the limited scale of the figure, these deaths are not visually represented, but the number is included in the graph.
