text: Figure 1 is a series of line graphs showing the cumulative number of Haemophilus influenzae cases reported to Health Protection Scotland per week by year. Each line represents a different year from 2017 to the end of the first quarter of 2021 and all years show a steady increase in cumulative number of cases per week. The number of cases so far in 2021 is lower than for the corresponding periods in the previous four years.
