Frequency and Identification of Plasmodial Species in the NZABA Health Zone, Mbujimayi City (Democratic Republic of the Congo)

Method: We used the prospective method supported by the techniques of analysis of Medical Biology (malaria microscopy which consisted in taking blood samples to make thick drops and thin smears), and the data were collected via Kobo software—collect V.2021.2.4 and analyzed by using SPSS.20 software. This study is carried out in the NZABA Health Zone. It is limited to determining the frequency and identifying plasmodial species. Results: After collecting and analyzing the data, we arrived at the results according to the following: out of 201 subjects subjected to our study, 140 people had a positive thick drop, or 69.7% had a thick drop positivity rate; the women come first with 83 cases or 59.70%; the age group from 0 to 15 years is much more affected by malaria, with 44.3%, followed by the age group of 41 years and over; the age groups between 16 to 30 and 31 to 40 occupy the bottom of the scale with 10 and 10.7 respectively. There is a predominance of Plasmodium falciparum at 97.4% followed by Plasmodium ovale at 2.14%. Plasmodium malariae is the last species with 0.7% and the bottom of the scale is occupied by Plasmodium vivax which has not been found. Conclusion: The frequency of malaria is 69.7%; Plasmodium falciparum is predominant with 97.4%. 3% of malaria cases escape the rapid diagnostic test and consist of Plasmodium ovale at 2.14% and Plasmodium malariae at 0.7%. Plasmodium vivax was not found; women come first with 83 cases or 59.70% followed by men with 57 cases or 40.30%; the age group from 0 to 15 years is the most affected.
