There are few estimates of influenza burden in the WHO Region for the Eastern Mediterranean. In this study we estimated the burden of severe acute respiratory infection (SARI) and influenza-associated SARI (F-SARI) in selected provinces of Islamic Republic of Iran, the trends of SARI and confirmed cases of influenza (F-SARI) over 12 months (seasonality), and the age groups most at risk. Using the electronic Iranian influenza surveillance system and data of cases in sentinel hospitals of 3 selected provinces, we estimated the monthly trend (seasonality) of incidence for SARI and F-SARI, overall incidence of SARI and F-SARI and their disaggregation by age with the aid using the Monte Carlo technique. The age groups most at-risk were children aged under 2 years and adults older than 50 years. ‫و‬

Introduction/Objective: Hydatid parasitic infection in humans can be caused by the parasite Echinococcus. Hydatid cysts form mainly in the liver and lungs. Cysts can rarely be found in other organs. Hydatid cyst in the pelvis can be secondary to rupture of the hydatid cyst in the spleen or kidneys. Primary pelvic hydatid cysts are very rare. Complications and symptoms of hydatid cyst depend on its location. Surgery is the basis of treatment for hydatid cysts.
