Abstract
Background:
Cutaneous leishmaniasis (CL) is a neglected worldwide, zoonotic, vector-borne, tropical disease that is a threat to public health. This threat may spread from endemic to non-endemic areas. Current research has exploited epidemiological, molecular and phylogenetical studies to determine the danger of an outbreak of CL in the borderline area between northern and central Iraq from 2014-2017.
Methodology/principal findings:
For the first time, using sequence analysis of the cytochrome b gene, the occurrence of CL in the borderline area between northern and central Iraq was confirmed to be due to Leishmania major. The phylogenetic analysis indicated that it was closely related to the L. major MRHO/IR/75/ER strain in Iran.
Conclusions and significance:
In conclusion, the genotype confirmation of the L. major strain will improve our understanding of the epidemiology of the disease. This is important for facilitating control programs to prevent the further spread of CL. Furthermore, this area could be considered as a model for further research on the risk of global CL epidemics in other non-endemic countries where both reservoir hosts and sandfly vectors are present.
