  • Due to the limitations of the data, the period analysed in 2021 was from January to April. To avoid the interference of zoonotic disease’s seasonality trends, the average monthly incidences and mortalities in 2020 and 2015–2019 were computed from January to April 2020 and from January to April 2015–2019, respectively.

  • *Indicates that the monthly incidence of the disease has a significant long-term downward trend.

  • †Indicates that the monthly mortality of the disease has a significant long-term downward trend.
