Systems for disease vector control should be effective, efficient, and flexible to be able to tackle contemporary challenges and threats in the control and elimination of vector-borne diseases. As a priority activity towards the strengthening of vector control systems, it has been advocated that countries conduct a vector-control needs assessment. A review was carried out of the perceived needs for disease vector control programs among eleven countries and subnational states in South Asia and the Middle East.

Article Synopsis
  • Phleboviruses are divided into two main groups: the sandfly fever group (spread by sandflies and mosquitoes) and the Uukuniemi group (spread by ticks).
  • The study focused on identifying sandfly species and detecting sandfly-borne viruses (SBVs) in Iran, using PCR techniques.
  • Researchers identified five positive specimens for phleboviruses, shedding light on the molecular epidemiology of Tehran virus, sandfly fever Sicilian virus, and Karimabad virus in the region.

Background: Dengue fever as a mosquito-borne disease, has rapidly spread due to climate change, globalization, and human behavior. Iran is prone to dengue fever, as its vector recently has been found in the country. This study aimed to assess predictors of dengue preventive practices based on Precaution Adoption Process Model (PAPM) factors in West Azerbaijan province, northwest of Iran.
