Relevance. The geographical spread of HIV infection among the population of various administrative territories is very heterogeneous. The Tyumen region, due to its vast territory and the significant remoteness of some areas from the regional center, is of particular interest in the framework of considering the territorial features of the spread of HIV.Aims. To consider peculiarities of the spread of hiv infection among urban and rural residents of the Tyumen region in 1993–2019.Materials & Methods. Statistical data of the «Center for the Prevention and Control of AIDS» in the period from 1993 to 2019, annual form No. 61 «Information on the contingents of HIV patients» for 2006–2019, materials of the state report «On the sanitary and epidemiological situation in the Tyumen region» for 2013–2019. Methods of epidemiological observation were used in the work: analytical and descriptive-evaluative with the use of methods of retrospective and operational analysis and statistical methods.Results and Discussions. A specific feature of the spread of HIV infection among urban and rural residents is the tendency to exceed the regional incidence rate in a number of territories. Analysis of epidemiological data for the period under review showed that all territories of the region are involved in the epidemiological process of HIV infection, and in a number of territories the prevalence rate exceeds the average Russian level. HIV prevalence as of December 31, 2019 was 728.2 per 100 thousand people in Russia. In 17 administrative territories of the Tyumen region the infection rate is higher than the national average level and is per 100 thousand population in the city of Tobolsk – 1903.3, in the districts of Uvat – 1486.2, Tobolsk – 1440.5, Nizhnetavda – 1354.9, Tyumen – 1344.1, Yalutorovsk – 1327.6), in the city. Tyumen – 1249.3, in the districts: Vagay – 1195.2, Zavodoukovsky – 1119.2, in Ishim – 951.8, in the districts: Yarkovsky – 889.6, Vikulovsky – 881.3, Yurginsky – 846.9, Ishimsky district – 842.1, Aromashevsky – 851.6, Isetovsky – 754.4, Uporovsky district – 734.7.Conclusions. The HIV epidemic in the Tyumen region is determined by its economic and geographic location and by the presence of exceptional epidemiologically significant prerequisites for the intensive spread of HIV, in particular, by the routes through which large quantities of drugs are illegally transported (drug trafficking from the northeast).

The HIV epidemic has been going on for nearly thirty years, it is a heterogeneous, dynamic and highly resistant to countermeasures. The Leningrad Region and the city of St. Petersburg today are referred to the most affected regions of the Russian Federation, as nearly 1% of the population of this city has HIVpositive status. Despite the decline in the HIV infection incidence of the resident population of the Central District, the epidemiological situation for HIV infection remains to be tense, due to the increase in the cumulative number of HIV-infected and AIDS patients, the increase ofthe morbidity rate and mortality in co-infected patients with HIV/tuberculosis, activation of the output of the epidemic in vulnerable groups into the general population. At the same time, a cohort of HIV-infected patients with a high risk of late detection of tuberculosis continues to form

Antibody Tests

The experience with human immunodeficiency virus (HIV) infection of a private inner-city sexually transmissible diseases (STD) clinic in Sydney was quantified. Between February 1984 and March 1988, 2073 of the Clinic's patients were tested for antibodies to HIV on 5095 occasions. Of those tested, 538 (26%) were positive for antibodies to HIV: 532 (98.9%) of the seropositives had practised male homosexual intercourse. This is the highest reported seroprevalence of HIV for any primary care service in Australia. Those individuals seropositive because of other risk behaviours were detected by voluntary contact tracing rather than by screening. Female prostitution was not found to be a risk factor for HIV. In general, rates of first HIV antibody tests were adversely affected by threatening legislation, and temporarily stimulated (among lower-risk persons) by a national television campaign. These data suggest that much of the counselling, detection and management of HIV infection in Australia is occurring in private practice, and that STD services (private and public) are at the forefront of the HIV epidemic. This has implications for disease surveillance and control, health services planning and medical education.

Abstract Background: Shanghai is an international city which has high proportion of entry travelers from all over the world. The HIV infection status of this population can reflect the global trend of HIV prevalence. Thus, a retrospective epidemic investigation was conducted to clarify the prevalence and characteristics of HIV infection among entry travelers who apply to residency in Shanghai. Methods: Totally 50830 entry travelers who applied to residency in Shanghai（2005-2016）were included. The HIV infection rate was confirmed based on the detection of HIV-1 antibody. Results: Among all the recruited entry travelers, 245 persons were determined HIV positive with infection rate of 0.48%. The detection rate of HIV in male was significantly higher than that in female (χ2=62.584, P<0.0001). Those aged 18-30 years, 31-40 years and >40years accounted for 34.3%, 39.6% and 26.1% of the infected population. There was no increase in trend of HIV prevalence rates among the sampling years (Cochran-Armitage Z=2.543, P=0.111). Proportions of individuals infected through homosexual transmission increased over the study period (Cochran-Armitage Z=5.41, P<0.001), while the proportion infected through heterosexual declined over time (Cochran-Armitage Z=3.38, P =0.001). Conclusion: The characteristics of HIV infection among foreign applicant to residency in Shanghai were clarified. The results would provide the necessary epidemiological data for monitoring the HIV epidemic among entry international travelers and contribute to the establishment of relevant policies and regulations for HIV control and prevention.

City centers worldwide are perceived as essential parts of the city, where city memories are preserved and its identity is expressed. They are planned to satisfy the functional requirements and pleasurable qualities of the city. Under the accelerating urbanization of the modern city, several challenges face these centers including demographic, economic, and environmental challenges. This requires a continuous and incremental urban development process based on clear strategy and action plans. Thus, this study focuses on urban development strategies of city centers, with a focus on Rafah city located in the Gaza Strip, Palestinian Territories. The geographic location of this city near the Palestinian-Egyptian borders makes it a promising commercial city at local and regional levels. Thus, the current situation of Rafah city center has been analyzed, and several development strategies have been proposed. This has been done through a field survey based on observation and a questionnaire directed to city center users. It has been found that there is a great potential of Rafah city center to be developed as a commercial center. In this regard, several strategies and required actions have been proposed in the fields of transportation, environmental quality, shopping activities, investment opportunities, and visual perception.

Many applications have relied on the hedonic pricing model (HPM) to measure the willingness-to-pay (WTP) for urban externalities and natural disasters. The classic HPM regresses housing price on a complete list of attributes/characteristics that include spatial or environmental amenities (or disamenities), such as floods, to retrieve the gradients of the market (marginal) WTP for such externalities. The aim of this paper is to propose an innovative methodological framework that extends the causal relations based on a spatial matching difference-in-differences (SM-DID) estimator, and which attempts to calculate the difference between sale price for similar goods within “treated” and “control” groups. To demonstrate the potential of the proposed spatial matching method, the researchers present an empirical investigation based on the case of a flood event recorded in the city of Laval (Québec, Canada) in 1998, using information on transactions occurring between 1995 and 2001. The research results show that the impact of flooding brings a negative premium on the housing price of about 20,000$ Canadian (CAN).

Human Cystic Echinococcosis

Abstract Purpose Human cystic echinococcosis (CE) is a zoonotic parasitic disease that constitutes a public health challenge and a socio-economic burden in endemic areas worldwide. No specific surveillance system of CE infections in humans exists in Lebanon. The incidence and trends over time have not been documented. The current study aimed to assess the demographic and epidemiologic features of human CE surgical cases over a 14-year period in the five main regions of Lebanon. Methods From 2005 to 2018, a total of 894 surgically confirmed cases of hydatidosis were recorded from five anatomy and pathology laboratories. Results The mean annual surgical incidence was 1.23/100,000 inhabitants. Over the span of these years, the incidence increased from 0.53 to 1.94 cases/100,000 inhabitants in 2005 and 2018, respectively. CE is present in Lebanon with an uneven distribution from one region to the other with higher prevalence in Bekaa (29.0%), a rural area where sheep raising is widespread. Human CE cases were more common in females (60.1%) than in males (39.9%) and a high burden of infection was reported for the age group of 30–39 years. Besides, 66.7% of the cases expressed only liver complications whereas, 20.5% showed predilection towards lungs. The 7.8% of cases presented cysts in other organs, and 1.3% showed multiple localizations. Additionally, predominant involvement of Echinococcus granulosus sensu stricto was recorded in human infections. Comparison of Echinococcus granulosus s.s. populations from different Mediterranean countries also revealed high gene flow among this region and sharing of alleles. Conclusion The current study is a step forward to fill the gap of knowledge for the hydatidosis in Lebanon where the lack of epidemiological data and control measures have resulted in higher incidence of human CE.

The aim of the study is to evaluate the preparedness of retirement and nursing homes in the city of Sassari at the end of the first wave of the severe acute respiratory syndrome coronavirus 2 epidemic, first by investigating the risk perception of epidemic outbreaks by the facility managers and subsequently by carrying out a field assessment of these facilities. To perform the field assessment, a checklist developed by the CDC (Infection Prevention and Control Assessment Tool for Nursing Homes Preparing for COVID-19) and adapted to the Italian context was used. Fourteen facilities took part in the survey (87.5%). The application of good practices for each survey area was expressed as a percentage with the following median values: restriction policies (87.5%), staff training (53.8%), resident training (67.6%), availability of personal protective equipment (41.7%), infection control practices (73.5%) and communication (80%). Among the facilities, considerable variability was observed in these evaluation fields: only the restriction policies and communication activities were applied uniformly. A discrepancy was found between perceived risk and real danger in the facilities, requiring targeted communication actions. At present, it is necessary to promote a new approach based on the prediction of critical events, thereby providing the means to effectively address them.
