Abstract

Background: Malaria is one of the important infectious blood diseases caused by the protozoan parasite of the genus of Plasmodium, and transmitted by female Anopheles mosquito bites. Malaria elimination plan is currently being followed in Hormozgan province. The robust malaria surveillance system with appropriate active case finding, especially asymptomatic cases, plays an important role in the malaria elimination programme.

Objectives: The main objectives of this research were to determine presence and prevalence of asymptomatic malaria cases and monitor asymptomatic parasitic reservoir in Jask district, Hormozgan province.

Methods: This cross-sectional study was aimed to evaluate and monitor asymptomatic cases in Jask district. The purpose and stages of the study were explained to all participants/parents and informed written consent was obtained. A total of 230 (124 females and 86 males) asymptomatic residents were randomly selected, and their blood samples (3 ml) were taken to assess Plasmodium infection using microscopic, RDT, and molecular (18ssrRNA) methods.

Results: Of the 230 studied cases, 54.8% were female and 454.2% were male. The age range was 4 to 65 years old, and the mean age was 24.5 years old. None of the diagnostic methods, including the microscopic, serological, and molecular techniques were found asymptomatic malaria cases in the study area.

Conclusions: It can be concluded that Malaria Elimination Programme is feasible in Jask region irrespective of the asymptomatic parasitic reservoir. The results also emphasize a robust and efficient malaria surveillance system to diagnose, treat the positive cases and monitor the treated cases successfully. Ongoing and continuous studies are recommended in the high-risk malarious area of Hormozgan province to monitor asymptomatic cases of malaria.
