Objective: In order to identify the types of Plasmodium species and to determine the parasites prevalence, a parasitological study based on thick drops and thin smears was carried out in March and September 2022 (two passages), in four sites (Ouro Tada, Tasha Haman Gawar, Tasha Koutourou and Mbikem) in the town of Mokolo, Far North Cameroon. 
Methodology: Blood samples were taken in accordance with laboratory techniques and procedures for the microscopic diagnosis of malaria as recommended by WHO (2010). A total of 3840 individuals were samples according to age (0 to 5 years, 6 to 9 years, 10 to 15 years and 16 to over). So 4 age groups x 4 sites x 2 passages + 60 girls + 60 boys) = 3840 individuals. 
Results: Of all the Plasmodium species identified (P. falciparum and P. malariae), P. falciparum showed a higher prevalence in the wet and dry seasons. The Ouro Tada site was the most contaminated in both seasons. Plasmodium falciparum showed a prevalence of 70.61% in Ouro Tada, 68.62% in Tasha Haman Gawar, 68.12% in Tasha Koutourou and 69.27% in Mbikem. As for Plasmodium malarae showed a prevalence of 31.04% in Ouro Tada, 31.37% in Tasha Haman Gawar, 31.18% in Tasha Koutourou and 30.71% in Mbikem. 
Conclusion: Among all the Plasmodium species identified (P. falciparum, P. malarae), P. falciparum showed a higher prevalence, followed by P. malarae.
