Unmasking species: A comprehensive review of their presence in Iran.

species are the causative agents of Lyme disease (LD) and tick-borne relapsing fever (TBRF) in humans and animals. These pathogens are transmitted through hard and soft ticks. The increasing tick population, influenced by climate change, underscores the urgent need for enhanced research on tick-borne diseases. Iran, situated in southwestern Asia, boasts a diverse climate that supports a wide range of tick species and their vertebrate hosts. While TBRF is endemic to Iran, recent reports suggest the presence of LD in the country as well. Understanding the various species, their tick vectors, human cases, affected reservoirs, and geographical distribution is crucial for assessing the epidemiology of TBRF and LD in Iran. This comprehensive review examines the epidemiological patterns, geographical distribution, detection methods for these pathogens, providing critical insights into their public health significance.
