Abstract
The prevalence of HIV/AIDS among people in midlife and late adulthood has been increasing in Western countries over the last decade. We analyzed data from a prospective, observational multi-centre study on individuals newly diagnosed with HIV between January 2004 and March 2007 in 10 public counselling and testing sites in Latium, Italy. At diagnosis, routine demographic, epidemiological, clinical and laboratory data are recorded, and patients are asked to complete a questionnaire investigating socio-demographic and psycho-behavioural aspects. To analyze the association of individual characteristics with age, we compared older adults (> or = 50 years) with their younger counterpart (18-49 years). To adjust for potential confounding effect of the epidemiological, clinical and behavioural characteristics, to identify factors associated with older age at HIV diagnosis, multivariate logistic regression analysis was performed. Overall, 1073 individuals were identified, 125 of whom (11.6%) were aged 50 years or above. The questionnaire was completed by 41% (440/1073). Compared with their younger counterparts, a higher proportion of older patients were males, born in Italy, reported heterosexual or unknown HIV risk exposure, were never tested for HIV before and were in a more advanced stage of HIV infection at diagnosis. In addition, older adults had a lower educational level and were more frequently living with their partners or children. With respect to psycho-behavioural characteristics, older patients were more likely to have paid money for sex and have never used recreational drugs. Interestingly, no differences were found regarding condom use, which was poor in both age groups. These findings may have important implications for the management of older adults with HIV, who should be targeted by appropriate public health actions, such as opportunistic screening and easier access to healthcare. Moreover, strategies including information on HIV and prevention of risk behaviours are needed.

Abstract
A bundle is a small, straightforward set of scientifically grounded elements (generally three to five) that, when implemented together, result in better outcomes than when implemented individually. Bundles have found their greatest application in the prevention of Healthcare-Associated Infections (HAIs). The bundles examined concern the prevention of VAP for patients undergoing mechanical ventilation, the prevention of BSI CVC, the prevention of surgical side infection (SSI), the prevention of catheter-associated urinary tract infections, the prevention of infection by Clostridium difficile and the treatment of sepsis. Studies show a reduction in mortality rates, infection rates and in the length of hospital stay. Some studies have low statistical significance due to the small number of patients examined, and future studies will be needed to confirm these results.

Abstract
Background Five known human coronaviruses infect the human respiratory tract: HCoV-OC43, HCoV-229E, SARS-CoV, HCoV-NL63 and HCoV-HKU1. Objectives To evaluate the prevalence of HCoV-NL63 in hospitalized adult patients and to perform molecular characterization of Italian strains. Study Design HCoV-NL63 was sought by RT-PCR in 510 consecutive lower respiratory tract (LRT) samples, collected from 433 Central-Southern Italy patients over a 1-year period. Phylogenetic analysis was performed by partial sequencing of S and ORF1a. Additional S sequences from Northern Italy were included in the phylogenetic trees. Results HCoV-NL63 was detected in 10 patients (2.0%) with symptomatic respiratory diseases, mainly during winter. Phylogenetic analysis indicated a certain degree of heterogeneity in Italian isolates. The ORF1a gene clustering in phylogenetic trees did not match with that of the S gene. Conclusions As observed by others, HCoV-NL63 is often associated with another virus. Phylogenetic characterization of HCoV-NL63 circulating in Italy indicates that this virus circulates as a mixture of variant strains, as observed in other countries.

Abstract
Viral respiratory diseases may be characterized by rapid diffusion in population, that often cause epidemic outbreaks or pandemic. Besides, typical high mutations of involved virus (almost always influenza virus) can reduce the validity of the up to date available vaccine. The achievement of new vaccines can require prolonged period. In addition, the availability and efficacy of antiviral drugs against new viruses should be evaluated before their uses. Influenza virus replication occurs in the epithelial cells of the respiratory system, and viruses, present in contaminated secretions, spread mainly by aerosols generated during sneezing, coughing, and speaking. Direct and indirect contacts with contaminated fomites play a role, in transmission of viral infection, even if they are less relevant than aerosol transmission. In the absence of ready for use vaccines and active drugs, some "non-pharmaceutical" strategies can be considered decisive factors to reduce the diffusion of pandemic influenza. Hand washing and disinfection procedures, isolation of ill persons, different indication for use of surgical masks and respiratory masks have to be carefully considered.

Abstract
The SARS epidemic, the threat of bioterrorism, and recent examples of imported highly infectious diseases (HID) in Europe have all highlighted the importance of competent clinical and public health management of infectious disease emergencies. Although the European Union of Medical Specialists in Europe and the Infectious Diseases Society of America have developed curricula for training in infectious disease medicine, neither of those mentions training in the management of HIDs. The European Network for Infectious Diseases (EUNID, http://www.eunid.com) is a European Commission co-funded network of experts in HID management, created to help improve the preparedness for HID emergencies within Europe. One of EUNID's agreed tasks is the development of a curriculum for such a training. Between April 2005 and September 2006, EUNID developed a curriculum and accompanying training course on the basis of a questionnaire that was sent to all country representatives and discussion, followed by amendment of drafts shared through the project website, and a final consensus meeting. The resulting curriculum consists of a two-module course covering the core knowledge and skills that healthcare workers need to safely treat a patient who has, or who may have, an HID. The first module introduces theoretical aspects of HID management, including disease-specific knowledge, infection control, and the public health response, through didactic teaching and class-based discussion. The second module involves a "skill station" and a clinical scenario, and equips trainees with relevant practical skills, including the use of specialised equipment and teamwork practice in patient management. Together, the curriculum and course contribute to the creation of a common framework for training healthcare professionals in Europe, and although they are designed primarily for clinicians that are directly involved in patient care, they are relevant also to public health professionals and others who may be involved in HID management and emergency response.

Abstract
In the last 2 decades, successive outbreaks caused by new, newly recognised and resurgent pathogens, and the risk that high-consequence pathogens might be used as bioterrorism agents amply demonstrated the need to enhance capacity in clinical and public health management of highly infectious diseases. In this article we review these recent and current threats to public health, whether naturally occurring or caused by accidental or intentional release. Moreover, we discuss some components of hospital preparedness for, and response to, infectious disease of the emergencies in developed countries. The issues of clinical awareness and education, initial investigation and management, surge capacity, communication, and caring for staff and others affected by the emergency are discussed. We also emphasise the importance of improving the everyday practice of infection control by healthcare professionals.

Abstract
BACKGROUND A worker is considered to be hazardous to others when, in the course of performing a specific work task, his/her health problems (e.g., substance dependence, emotional disorders, physical disability, transmissible diseases) pose a risk for other workers' or the public's health and safety, or begins to interfere with ability to function in profession life. The presence of certain illnesses or the fact that a health care worker is impaired because of them do not necessarily imply that he, or she, is hazardous for others. Working in health care increases the probability that an impaired worker being hazardous for others. Management of hazardous workers requires new techniques and procedures, and specific policies. OBJECTIVE AND METHODS An interdisciplinary group of experts from medical, bioethical, legal and administrative disciplines, together with trade union and employers' representatives, is currently attempting to define a way to put prevention measures into practice in accordance with state laws and individual rights. RESULTS A consensus document is presented, covering critical aspects such as: social responsibility of the employer, risk management, informed consent, non compliance, confidentiality, responsibility of workers, disclosure of risk to patients, non-discrimination, counselling and recovery of impaired workers, effectiveness of international guidelines. CONCLUSIONS Occupational health professionals are obliged to adhere to ethical principles in the management of "hazardous" workers; the assessment of ethical costs and benefits for the stakeholders is the basis for appropriate decisions.

Infection 2006; 34:219-21.

Abstract
Background: The World Health Organization (WHO) has
recommended that a severe acute respiratory syndrome
(SARS) alert should be raised when two or more healthcare
workers (HCW) in the same health care unit fulfil the
SARS clinical criteria, with onset of illness in the same
10-day period. However, in a number of European countries
(including Italy) data on reasons for sickness absence are
not routinely collected within current HCW worker sickness
reporting systems, because of concerns about privacy. To
help plan for the implementation of the proposed alert
system in Italy, we aimed to determine the minimum number
of alert cases defining a cluster. Patients and Methods: Sickness absences longer than 7 days
in HCW employed in three hospitals in 2003, were identified
by checking the hospitals’ administrative databases. HCW
with onset of illness in the same 10-day period were
contacted and asked whether they have been diagnosed with
pneumonia. Results: Overall, 273 absences > 7 days were recorded and
36 clusters of at least two absences > 7 days were identified;
a total of 94 HCW were involved in these clusters. Only two
HCW involved in different clusters, reported pneumonia. Conclusion: The occurrence of clusters of two or more cases
of pneumonia in HCW in the same hospital unit appears to
be an uncommon event, and thus the alert system proposed
is not likely to result in large numbers of false positive
alerts. However, it may be difficult to implement this alert
system in countries where clinical data on sickness absences
are not routinely collected, and alternative mechanisms
should be considered.

Abstract
BACKGROUND Factors that influence the risk for HCV infection after occupational exposure to hepatitis C virus (HCV) have not yet been determined. The objective of this study was to assess potential risk factors for Hepatitis C seroconversion after occupational exposure to HCV. METHODS We conducted a European matched case-control study from 01/01/1991 through 31/12/ 2002. Cases were Health Care Workers (HCWs) who were HCV seronegative at the time of exposure, sustained a documented exposure to HCV, and present documented HCV seroconversion temporally associated with the exposure. Controls-HCWs had a documented exposure to HCV, were HCV seronegative at the time of exposure, and remained so at least 6 months later. Controls were matched to cases for the center and the time period of the exposure occurrence. RESULTS 60 cases and 204 controls were included. All cases were exposed to HCV-infected materials through percutaneous injuries. Those for whom information was available (61.6%) were exposed to viremic source patients. Multivariate conditional logistic regression analysis, in which HCV viral load was not introduced because of missing values, identified needle placed in the source patient's vein or artery (Odds Ratio [OR]=100.1; 95% Confidence Interval [CI]=7.3-1365.7), deep injury (OR=155.2; 95%CI=7.1-3417.2), and HCW's gender (M vs. F: OR=3.1; 95%CI=1.0-10.0) as risk factors for HCV infection. In univariate unmatched analysis the risk of HCV transmission was increased 11-fold (C195%=1.1-114.1) in HCWs exposed to sources with a viral load>6 log10 copies/mL when compared to sources with a HCV viral load<4 log10 copies/mL. CONCLUSION The risk of HCV transmission after percutaneous exposure increases with a larger volume of blood, and, a higher titer of HCV in the source patient's blood. The role of HCW's gender need to be further investigated. The results of this study have important implications for counselling and follow-up of HCWs after exposure.

Abstract
BACKGROUND Additional studies are required to identify risk factors for hepatitis C virus (HCV) transmission to health care workers after occupational exposure to HCV. METHODS We conducted a matched case-control study in 5 European countries from 1 January 1991 through 31 December 2002. Case patients were health care workers who experienced seroconversion after percutaneous or mucocutaneous exposure to HCV. Control subjects were HCV-exposed health care workers who did not experience seroconversion and were matched with case patients for center and period of exposure. RESULTS Sixty case patients and 204 control subjects were included in the study. All case patients were exposed to HCV-infected fluids through percutaneous injuries. The 37 case patients for whom information was available were exposed to viremic source patients. As risk factors for HCV infection, multivariate analysis identified needle placement in a source patient's vein or artery (odds ratio [OR], 100.1; 95% confidence interval [CI], 7.3-1365.7), deep injury (OR, 155.2; 95% CI, 7.1-3417.2), and sex of the health care worker (OR for male vs. female, 3.1; 95% CI, 1.0-10.0). Source patient HCV load was not introduced in the multivariate model. In unmatched univariate analysis, the risk of HCV transmission increased 11-fold for health care workers exposed to source patients with a viral load >6 log(10) copies/mL (95% CI, 1.1-114.1), compared with exposures to source patients with a viral load < or =4 log10 copies/mL. CONCLUSION In this study, HCV occupational transmission was found to occur after percutaneous exposures. The risk of HCV transmission after percutaneous exposure increased with deep injuries and procedures involving hollow-bore needle placement in the source patient's vein or artery. These results highlight the need for widespread adoption of needlestick-prevention devices in health care settings, together with other preventive measures.

Abstract
Exposure prevention is the primary strategy to reduce the risk of occupational bloodborne pathogen infections in healthcare workers (HCW). HCWs should be made aware of the medicolegal and clinical relevance of reporting an exposure, and have ready access to expert consultants to receive appropriate counselling, treatment and follow-up.
Vaccination against hepatitis B virus (HBV), and demonstration of immunisation before employment are strongly recommended. HCWs with postvaccinal anti-HBs levels, 1-2 months after vaccine completion, >10 mIU/mL are considered as responders. Responders are protected against HBV infection: booster doses of vaccine or periodic antibody concentration testing are not recommended. Alternative strategies to overcome non-response should be adopted.
Isolated anti-HBc positive HCWs should be tested for anti-HBc IgM and HBV-DNA: if negative, anti-HBs response to vaccination can distinguish between infection (anti-HBs >50 mUI/ml 30 days after 1st vaccination: anamnestic response) and false positive results(anti-HBs >10 mUI/ml 30 days after 3rd vaccination: primary response); true positive subjects have resistance to re-infection. and do not need vaccination
The management of an occupational exposure to HBV differs according to the susceptibility of the exposed HCW and the serostatus of the source. When indicated, post-exposure prophylaxis with HBV vaccine, hepatitis B immunoglobulin or both must be started as soon as possible (within 1-7 days).
In the absence of prophylaxis against hepatitis C virus (HCV) infection, follow-up management of HCV exposures depends on whether antiviral treatment during the acute phase is chosen. Test the HCW for HCV-Ab at baseline and after 6 months; up to 12 for HIV-HCV co-infected sources. If treatment is recommended, perform ALT (amino alanine transferase) activity at baseline and monthly for 4 months after exposure, and qualitative HCV-RNA when an increase is detected.

Abstract
Data from AIDS surveillance systems in the World Health Organization European region (1993-2001) were analysed to describe the main epidemiological aspects of recurrent bacterial pneumonia (RBP) as AIDS-defining illness (ADI) in Europe. Among the 153 756 AIDS cases analysed, 5796 (3.8%) had RBP. The proportion of RBP was higher (8.3%) in eastern than in western Europe (3.6%), possibly because of a greater propensity of certain countries to diagnose RBP. In western Europe, the proportion of RBP as ADI appeared to increase over time up to 1998 (from 2.5% to 4.5%), and declined thereafter (3.3% in 2001). RBP was strongly associated with intravenous drug use (odds ratio 3.0, 95% CI 2.7-3.3), whereas it did not differ in age groups or geographical areas. The study findings confirm the crucial role of intravenous drug use in the occurrence of RBP and suggest that highly active antiretroviral therapies mi.ht have had a postponing impact on the relative frequency of RBP as ADI.

Abstract
BACKGROUND HIV spread among low-risk populations through heterosexual intercourse is a major public health concern. This study was aimed at describing prevalence and determinants of HIV infection among Italian low-risk subjects seeking their first lifetime HIV test. PATIENTS AND METHODS Information collected between January 1990 and December 2000 at a major counseling and testing site in Rome, Italy, was analyzed. Multiple logistic regression odds ratios (OR) and 95% confidence intervals (CI) were computed. RESULTS Among the 14,313 study subjects, 64 (0.4%) were seropositive for HIV infection. HIV seropositivity increased with age (OR = 4.0, 95% CI: 2.1-7.6 for >/= 40 years vs 18-24), and it seemed to be more common among men (OR = 1.6, lower 95% CI:0.9). There was no evidence of temporal variations, whereas motivations for HIV testing were strongly associated with HIV prevalence. Testing for alarming symptoms (OR = 13.8) or for heterosexual intercourse (OR = 11.0) were associated with a more than 10-fold increased HIV risk. CONCLUSION Our findings are consistent with data from other industrialized countries and they show a strong association between HIV seropositivity and reason for first-time testing. Moreover, they indicate a stable trend of HIV prevalence among low-risk persons in the last decade. Further studies on time trends in low-risk populations would be useful to evaluate current HIV prevention programs.

Abstract
The US cases of anthrax in 2001 and the recent severe acute respiratory syndrome outbreak have heightened the need for preparedness and response to naturally emerging and re-emerging infections or deliberately released biological agents. This report describes the response model of the Istituto Nazionale per le Malattie Infettive Lazzaro Spallanzani (INMI), Rome, Italy for managing patients suspected of or affected by smallpox or viral haemorrhagic fever (VHF) either in the context of an intentional release or natural occurrence. The INMI is Italy's leading hospital in its preparedness and response plan to bioterrorism-related infectious agents. All single and double rooms of INMI are equipped with negative air pressure, sealed doors, high efficiency particulate air (HEPA) filters and a fully-equipped anteroom; moreover, a dedicated high isolation unit with a laboratory next door for the initial diagnostic assays is available for admission of sporadic patients requiring high isolation. For patient transportation, two fully equipped ambulances and two stretcher isolators with a negative pressure section are available. Biomolecular and traditional diagnostic assays are currently performed in the biosafety level 3/4 (BSL 3/4) laboratories. Continuing education and training of hospital staff, consistent application of infection control practices, and availability of adequate personnel protective equipment are additional resources implemented for the care of highly infectious patients and to maintain the readiness of an appropriately trained workforce to handle large scale outbreaks.

Abstract
Our research aimed to describe infectious disease mortality in Italy between 1969 and 1999, with particular emphasis on sex, age, and geographic differences. Using mortality data provided by the Italian Central Institute for Statistics (ISTAT), we evaluated all codes of the ICD8 and ICD9 classifications to identify each cause of death attributable to infectious agents. Deaths for HIV/AIDS were excluded. Infectious diseases accounted for 1.7% of overall mortality between 1969-1999, and our approach identified 57.5% of all deaths from infections not included in the ICD8 and ICD9 infectious disease codes. Up to 1994, the mortality for all infectious diseases showed a very strong downward trend, with a 6-fold decline. This trend levelled off in 1995-1999, mainly due to increasing deaths due to septicaemias, heart infections and hepatitis. An increasing proportion of deaths due to infectious diseases occurred in the elderly, from 48.1% in 1969-1979 to 77.3% in 1990-1999. Mortality rates were consistently higher in men than in women and showed a substantial geographic heterogeneity. In the newborn, mortality rates declined 10-fold and an inverse north-south geographic gradient persisted during the study period. This exhaustive methodological approach to identifying infectious causes of deaths allows us to better define the burden of infections on mortality and register downward trends similar to those found in other industrialized countries.
