- چکیده:
- چکیده انگلیسی: Background: Pandemic flu had at least two waves in Iran. Knowing how many of the general population were already exposed to this infection has a major impact on na-tional preventive measures. As of December 30, 2009, a total of 3672 confirmed cases of human infection with a novel Influenza A (2009 H1N1) virus had been reported in Iran with 140 deaths.
Objective: In this study we aim to measure, as a pilot study, the seroprevalence of positive antibody titer (humoral immunity) against 2009 H1N1 virus in Iranian population in Shiraz, Southern Iran.
Methods: Through cluster random sam-pling of families residing in Shiraz, 2553 subjects were selected and after a medical in-terview blood samples were taken and checked for polyclonal antibody against 2009 H1N1 antigen using hemagglutination inhibition assay. An antibody titer of more than 1:40 dilution was considered positive. Data were analyzed considering the demographic characteristics of the population and were compared among different age groups.
Results: 1504 (58.91%) samples were tested positive for the presence of polyclonal an-tibody against 2009 H1N1 virus. The prevalence of positive titers were significantly higher in 60 to 64 years old group and significantly lower in 20 to 24 years old group (p<0.05). Data did not differ based on other demographic characteristics or the history of flu like illnesses in the past 6 months.
Conclusion: High seroprevalence of antibody against 2009 H1N1 in the sera of our subjects describes either a high level of pre-existing immunity against H1N1 in Iranian population or a high rate of asymptomatic infection in our area compared to other countries.- انتشار مقاله: 16-05-1395

- چکیده انگلیسی: Background: Knowing the pattern of carbon monoxide (CO) poisoning in each region is vital for enhanced health planning. This study was designed to evaluate the epidemiologic pattern of unintentional acute CO poisoning in major cities of Fars province, southwest of Iran. Methods: This one-year cross-sectional study was carried out on unintentional CO poisoning incidents in Fars province, Iran, during the year 2011. The target population was people living in 7 major cities under supervision of Shiraz University of Medical Sciences including Shiraz, Eghlid, Neyriz, Khorambid, Marvdasht, Darab and Bavanat. Results: During 2011, 111 CO poisoning events occurred in the catchment area. These events involved 420 individuals (50.2% men) who were present during the poisoning event, of which 281 individuals with mean age of 27.8 ± 14.8 years were poisoned (46.5% men). The majority of CO poisoning events (77.3%) occurred in colder months of the year. Most events happened in urban areas (61.3%). The most common source of CO was water heater (27.5%) closely followed by gas stove (24.8%). The majority of poisoned patients were asleep during the event (150/281: 53.3%). The main causes of CO generation were inbound gas return (62.2%) and inappropriate ventilation (28.8%). The fatality rate of CO poisoning was significantly higher in men compared to women both in involved individuals and poisoned patients (P = 0.035, < 0.001; respectively). Moreover, poisoned victims who were asleep during the accident were more likely to die than those who were awake (14.3 vs. 3.7%, P < 0.001). Conclusion: Generally, the incidence and fatality rate of CO poisoning in the current study were comparable to those of the world statistics, but higher than in developed counties. Attention and emphasis on the safety of gas heaters, stoves, and other gas-powered appliances in residential places should be enforced.
