Abstract

Background: Asymptomatic malaria infection provides a reservoir of parasites, causing the persistence of malaria transmission. It accounts an important challenge for successful management of the control, elimination, and eradication programmes in any malaria-endemic region. This investigation was designed to assess the presence and the prevalence of asymptomatic carriers in Iranshahr district of Sistan and Baluchistan Province (2013-2014), with a considerable population movement, during the malaria elimination phase in Iran.

Methods: Finger-prick blood samples were collected from symptomless (n=250) and febrile (n=50) individuals residing in Iranshahr district, easthern Iran (Hoodian, Mand, Chah-e Giji, Jolgehashem, Esfand, Dalgan and Chahshour) during Jan 2013 to Dec 2014, and Plasmodium infections were detected using light microscopic and highly sensitive nested-PCR techniques.

Results: Thick and thin Giemsa-stained blood smears were negative for Plasmodium parasites. In addition, based on nested-PCR analysis, no P. vivax, P. falciparum, and P. malariae parasites were detected among the studied individuals.

Conclusion: Investigation the absence of asymptomatic carriers in Iranshahr district was illustrated and achieving malaria elimination in this area is feasible in a near future.
