Dengue fever, caused by the dengue virus and spread mainly by Aedes mosquitoes, is a significant public health concern in tropical regions. Bushehr Province in southern Iran, with its conducive climate for mosquito breeding, shows limited data on dengue prevalence, prompting this study. Researchers conducted a study across ten cities in Bushehr, collecting blood samples from 180 participants to detect dengue-specific antibodies through ELISA testing. Results revealed a prevalence rate of 2.78%, with positive cases found in Bushehr, Dashtestan, and Tangestan, indicating localized transmission. These findings highlight the risk of dengue outbreaks and emphasize the need for ongoing surveillance, vector control, and public education. Further research is needed to enhance understanding and inform health policies.

Ticks are known as domestic animals’ foreign parasites. They are causing economic damage and momentous in transmitting pathogens to the livestock industry in the world including Iran. This study was designed to define the livestock ticks frequency by seasonal and climate variety in Tehran province. Totally, 1623 poultry and livestock including chickens, sheep, camels, cows, pigeons, and dogs which were infected with ticks were studied in 2019, of which 121 soft ticks and 685 hard ticks were collected. In the current study, 14 species of ticks were detected including Argas persicus, Argas reflexus, Boophilus annulatus, Hyalomma asiaticum, Hyalomma marginatum, Hyalomma dromedarii, Hyalomma anatolicum, Haemaphysalis sulcata, Ornithodoros lahorensis, Haemaphysalis erinacei, Haemaphysalis inermis, Hyalomma detritum Rhipicephalus bursa, and Rhipicephalus sanguineus. The highest frequency was related to R. sanguineus (36.97%), and the lowest frequency was related to B. annulatus (0.37%). The lowest frequency of ticks was related to B. annulatus (0.37%) and the highest one was related to R. sanguineus (36.97%). Furthermore, the species of A. persicus (11.53%) and Hy. marginatum (18.85%) had the highest frequency after R. sanguineus. In mountainous and plain climates, ticks distribution indicated that among 806 ticks, 44.78% and 55.21% of them belonged to the mountainous and plain regions, respectively. This study demonstrated significant abundance of Soft and Hard ticks’ and diversity of them in poultry or livestock in various regions of Tehran province.
