Figure 2

Monthly counts of microscopy-confirmed cases and percentages of infections diagnosed by PCR for Plasmodium vivax and P. falciparum in study of microscopy sensitivity and decreased malaria prevalence in the urban Amazon Region, Brazil, January 2018–December 2021. Circles indicate Plasmodium vivax and triangles P. falciparum. Red circles and triangles represent study waves 1 (April‒May 2018) and 2 (September‒October 2018); green, waves 3 (May‒June 2019) and 4 (September‒October 2019); blue, waves 5 (October‒November 2020), 6 (April‒May 2021), and 7 (October‒November 2021). Error bars indicate 95% CIs for prevalence rates. Anonymized malaria case notifications were downloaded from the electronic database of the Ministry of Health of Brazil (http://200.214.130.44/sivep_malaria)
