Reports suggest non-falciparum species are an underappreciated cause of malaria in sub-Saharan Africa but their epidemiology is ill-defined, particularly in highly malaria-endemic regions. We estimated incidence and prevalence of PCR-confirmed non-falciparum and Plasmodium falciparum malaria infections within a longitudinal study conducted in Kinshasa, Democratic Republic of Congo (DRC) between 2015-2017. Children and adults were sampled at biannual household surveys and routine clinic visits.

- Non-falciparum malaria species are increasingly recognized as significant contributors to malaria cases in sub-Saharan Africa, particularly in the Democratic Republic of Congo (DRC), which has a high incidence of malaria.
- A longitudinal study in Kinshasa Province (2015-2017) found that the incidence of non-falciparum species was 11% for Plasmodium vivax and 7% for Plasmodium ovale within one year, while the incidence for Plasmodium falciparum was significantly higher at 67%.
- Non-falciparum infections were more common in rural areas and among school-age children, and while there were some associations with anemia, they weren't consistent, indicating that

Excitation of the porphyrins within this molecule with subpicosecond laser pulses results in single or double reduction of the acceptor depending on the light intensity. The singly and doubly reduced electron acceptors absorb light strongly at 713 and 546 nanometers, respectively.
