GIS Determination of Malaria Hot Spots in Qeshm Island,Iran
2019
Malaria disease is considered a healthy challenge in the south of Iran. Anopheles
stephensi is more responsible for the transmission of Plasmodium vivax to
indigenous people in the endemic areas of Iran. Since GIS is beneficial tool
in epidemiological study of tropical infections, all data were recorded into this
software and spatial mapping of our site was provided. In total, 173 cases were
reported during 2008-2017 from Qeshm Island, Hormozgan province, south of
Iran. Data was analyzed by ArcGIS v 10.5 to depict the risky and hot spots related
to our site. Winpepi v 3.18 was applied to evaluate the short seasonal peaks. Larak
Island is located at the east of Qeshm Island where was identified as a cold spot of
malaria transmission. Four districts including central part (Qeshm city, Dargahan &
laft), Ramkan, Suza, and Hengam determined as the hot spots of malaria infection.
Seasonal patterns appeared the significant short peak of 2 months (September-
October) and August-October (P<0.005). In addition, 5 months (June to October)
were more involved with malaria disease. This study presented that the foreign
laborers as imported malaria cases were more involved groups in Qeshm Island. In
order to accelerate the elimination phase of malaria, GIS mapping can be used for
monitoring hot spots authentically.
