Antibiotic Resistance in Streptococcus pneumoniae after Azithromycin Distribution for Trachoma

Figure 2

(a) Prevalence of azithromycin resistance amongst pneumococcus carriers plotted against time in studies with low-frequency azithromycin provision. The error bars show 95% confidence intervals about the proportions. (b) Prevalence of azithromycin resistance amongst pneumococcus carriers plotted against time in studies with high-frequency azithromycin provision or high baseline resistance. The error bars show 95% confidence intervals about the proportions.
