Figure 4

Avian influenza virus (AIV) isolation from roost water of cranes in the Izumi Plain, Japan. Weekly representation illustrates the numbers of AIV-positive allantoic fluid samples during the 2020–21 (A) (13), 2021–22 (B) (18), and 2022–23 (C) winter seasons. Bars show AIV isolates containing HPAIV H5 and those containing LPAIV. The weekly chart displays the number of AIV-positive allantoic fluid samples. HPAIV, highly pathogenic avian influenza virus; LPAIV, low pathogenicity avian influenza virus.
