Prevalence of Plasmodium species in Badr Governorate, Madinah Province, Saudi Arabia using microscopy and rapid diagnostic test.

Abstract

Malaria infection still represents a notable public health risk in Saudi Arabia. This cross-sectional study aimed to determine the prevalence of Plasmodium species among clinically suspected cases who presented at Badr General Hospital and healthcare facilities in selected regions of Badr Governorate, Madinah Province, Saudi Arabia between January 2021 and January 2022. A total of 493 suspected patients were recruited from Badr Governorate, investigated for malaria infection using CBFME and rapid diagnostic test- CareStart Malaria Pf/PAN (HRP2/pLDH) Ag Combo rapid diagnostic tests. The results showed that malaria infection was 34 (6.89%) cases among 493 suspected patients using microscopic examination as reference test. Moreover, subjects aged 31 to 40 years and those aged 51 to 60 years had the highest (50%) and lowest (8.82%) percentages of malaria cases. Plasmodium vivax (19/34, 55.88%) was higher than P falciparum (15/34, 44.1%) as the causative agents of malaria cases. The majority of malaria cases (29/34, 80.9%) among non-Saudi mainly from Sudan (15/34, 44.1%), Pakistan (5/34, 14.7%), Bangladesh (5/34, 14.7%) and India (4/34, 11.76%) whereas malaria cases among Saudis (5/34, 14.7%). In addition, the majority of malaria cases (32/34, 94.11%) among male subjects while (2/34, 5.88%) among females. The current study revealed that malaria transmission is still active in Badr Governorate, Madinah Province, Saudi Arabia and represents a public health concern. Further screening implements and continuous epidemiological monitor of the status of malaria infection in Kingdom of Saudi Arabia are thus warranted to improve its controlling activities and eradicate malaria endemicity in the country.
