A graph showing a summary of the total number of pertussis cases reported by year with an emphasis on 2019. In total for each year there have been: 335 in 2016; 358 in 2017; 326 in 2018; 392 in 2019; 215 in 2020; and 45 in 2021.

The number of pertussis cases reported in December was lower than the previous month, and was below the previous 5-year average. Elevated case counts in early 2020 may be due to a change in the case indentified for pertussis.
