In a World Health Organization (WHO)–sponsored study in the Solomon Islands, an intervention of mass treatment with ivermectin or permethrin led to a decrease in prevalence of scabies from 25% to less than 1%, as well as a decrease in the prevalence of pyoderma (secondary infection) from 40% to 21%. There was also a decline in hematuria, which was a sign of renal damage by group A Streptococcus secondary infection in children. [55] Treatment also decreased occurrence of streptococcal skin disease. Similar successes have been reported in other populations. [56]
