From: Malaria resurgence: a systematic review and assessment of its causes
Malaria resurgence in Latin America appears strongly correlated with weakened IRS programmes [75]. The blue line represents slide positivity (left axis) and the pink bars depict the number of houses sprayed with IRS per 1,000 population[54, 79]. Gray bars represent averages of surrounding years where no data on IRS was available in a particular year (otherwise the lack of a bar indicates zero houses sprayed).
