New Approaches to Prevent Healthcare-Associated Infection.

Healthcare-associated infection (HCAI) in hospitals mainly results from unsolved but well-identified causes such as hand hygiene, overuse of catheters, and to a lesser extent, the airborne transmission of infectious agents caused by the misuse of respiratory precautions. The aims of the Institut Hospitalo-Universitaire Méditerranée Infection are to develop new approaches to fight HCAIs. Among them, new technologies that allow for the traceability of care and good practices reminders have been developed concomitantly to an anthropological approach, facilitating acceptability by healthcare workers. While the automated continuous monitoring system is validated and commercially available, some other technologies are still under clinical evaluation or in the early development phase. Quorum sensing-based biotechnologies are developed with the aims to fight against wound colonization.

Short-term economic impact of the Zika virus outbreak.

Zika virus (ZIKV) is mainly transmitted by mosquitoes bites. However, transmission by sexual contacts has been reported in 11 non endemic countries. The rapid spread of ZIKV in Latin American and Caribbean Countries (LCR), person-to-person transmission and perceived risk on people's well being can affect the emerging economies of LCR which historically dependent on truism. Here we present an analysis on economic outputs for assessing the current impact of ZIKV on markets. Our analysis show an unexpected resilience of LCR markets to international alerts. This positive response represents an opportunity to scale-up interventions for preventing the further spreading of the ZIKV epidemic.

Isolation facilities for highly infectious diseases in Europe--a cross-sectional analysis in 16 countries.

BACKGROUND: Highly Infectious Diseases (HIDs) are (i) easily transmissible form person to person; (ii) cause a life-threatening illness with no or few treatment options; and (iii) pose a threat for both personnel and the public. Hence, even suspected HID cases should be managed in specialised facilities minimizing infection risks but allowing state-of-the-art critical care. Consensus statements on the operational management of isolation facilities have been published recently. The study presented was set up to compare the operational management, resources, and technical equipment among European isolation facilities. Due to differences in geography, population density, and national response plans it was hypothesized that adherence to recommendations will vary. METHODS AND FINDINGS: Until mid of 2010 the European Network for Highly Infectious Diseases conducted a cross-sectional analysis of isolation facilities in Europe, recruiting 48 isolation facilities in 16 countries. Three checklists were disseminated, assessing 44 items and 148 specific questions. The median feedback rate for specific questions was 97.9% (n = 47/48) (range: n = 7/48 (14.6%) to n = 48/48 (100%). Although all facilities enrolled were nominated specialised facilities' serving countries or regions, their design, equipment and personnel management varied. Eighteen facilities fulfilled the definition of a High Level Isolation Unit'. In contrast, 24 facilities could not operate independently from their co-located hospital, and five could not ensure access to equipment essential for infection control. Data presented are not representative for the EU in general, as only 16/27 (59.3%) of all Member States agreed to participate. Another limitation of this study is the time elapsed between data collection and publication; e.g. in Germany one additional facility opened in the meantime. CONCLUSION: There are disparities both within and between European countries regarding the design and equipment of isolation facilities. With regard to the International Health Regulations, terminology, capacities and equipment should be standardised.

Common health hazards in French pilgrims during the Hajj of 2007: a prospective cohort study.

BACKGROUND: The majority of published studies on Hajj-related diseases were based on hospitalized patient cohorts. METHODS: A total of 545 Hajj pilgrims from Marseille were enrolled in a prospective epidemiological study to evaluate the incidence of common health hazards. They were administered a questionnaire before traveling addressing demographic factors and health status indicators and a post-travel questionnaire about travel-associated diseases. RESULTS: Respondents had a median age of 61 years and originated mainly from North Africa (81%). A significant proportion of individuals had chronic medical disorders such as walking disability (26%), diabetes mellitus (21%), and hypertension (21%). A total of 462 pilgrims were administered a questionnaire on returning home. A proportion of 59% of travelers presented at least one health problem during the pilgrimage and 44% of the cohort attended a doctor during travel; 3% were hospitalized. Cough was the main complaint among travelers (attack rate of 51%), followed by headache, heat stress, and fever. Few travelers suffered diarrhea and vomiting. Cardiovascular diseases, neurological disorders, trauma, skin and gastrointestinal problems were not frequently observed in our survey, suggesting that their prevalence among the causes of admission to Saudi hospitals reflects a bias of selection. Cough episodes were significantly more frequent in individuals >55 years. We also evidenced that women were more likely to present underlying chronic cardiovascular disorder and diabetes compared to men and that they more frequently suffered from cough episodes associated with fever during the Hajj. CONCLUSIONS: Health risks associated with the Hajj in our experience are much more related to crowding conditions than to travel. Our work suggests that the studies performed in Saudi specialized units probably overestimate the part of certain diseases within the spectrum of Hajj-associated diseases. Our results also suggest that old female Hajjes should be considered as a high-risk population and that preventive measures should be reinforced before departing for Saudi Arabia.
