Epidemiology, pathogenesis, clinical presentation and management of TB in patients with HIV and diabetes.

Caused by Mycobacterium tuberculosis, TB is the leading cause of death from an infectious disease. HIV and diabetes are recognised risk factors for progression of TB disease and both have a strong impact on the diagnosis and management of TB, threatening efforts to end TB globally. Here we provide the latest data on the complex interplay between these conditions. TB patients with HIV present systemic immune activation, increased HIV viral load, more severe clinical presentations and reduced success of TB therapy. Similarly, TB patients with diabetes are characterised by an exaggerated adaptive immunity, worsening of the clinical presentations and a higher risk for multidrug resistance and treatment failure. It is important to strengthen resources to prevent these comorbidities from occurring and to implement screening, early diagnosis and appropriate management strategies.

COVID-19 among healthcare workers in a specialist infectious diseases setting in Naples, Southern Italy: results of a cross-sectional surveillance study.

A coronavirus disease 2019 (COVID-19) surveillance study was performed in March-April 2020 among asymptomatic healthcare workers (HCWs) at a specialist infectious diseases hospital in Naples, Italy. All HCWs underwent two rounds of molecular and serological testing for severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). One hundred and fifteen HCWs were tested; of these, two cases of infection were identified by reverse transcriptase polymerase chain reaction and two HCWs were SARS-CoV-2 immunoglobulin G seropositive. The overall prevalence of current or probable previous infection was 3.4%. The infection rate among HCWs was reasonably low. Most of the infected HCWs had been asymptomatic for the preceding 30 days, which supports the need for periodic screening of HCWs for COVID-19.

Transportation capacity for patients with highly infectious diseases in Europe: a survey in 16 nations.

Highly infectious diseases (HIDs) are defined as being transmissible from person to person, causing life-threatening illnesses and presenting a serious public health hazard. In most European Union member states specialized isolation facilities are responsible for the management of such cases. Ground ambulances are often affiliated with those facilities because rapid relocation of patients is most desirable. To date, no pooled data on the accessibility, technical specifications and operational procedures for such transport capacities are available. During 2009, the 'European Network for HIDs' conducted a cross-sectional analysis of hospitals responsible for HID patients in Europe including an assessment of (a) legal aspects; (b) technical and infrastructure aspects; and (c) operational procedures for ground ambulances used for HID transport. Overall, 48 isolation facilities in 16 European countries were evaluated and feedback rates ranged from 78% to 100% (n = 37 to n = 48 centres). Only 46.8% (22/47) of all centres have both national and local guidelines regulating HID patient transport. If recommended, specific equipment is found in 90% of centres (9/10), but standard ambulances in only 6/13 centres (46%). Exclusive entrances (32/45; 71%) and pathways (30/44; 68.2%) for patient admission, as well as protocols for disinfection of ambulances (34/47; 72.3%) and equipment (30/43; 69.8%) exist in most centres. In conclusion, the availability and technical specifications of ambulances broadly differ, reflecting different preparedness levels within the European Union. Hence, regulations for technical specifications and operational procedures should be harmonized to promote patient and healthcare worker safety.

Highly infectious diseases in the Mediterranean Sea area: Inventory of isolation capabilities and recommendations for appropriate isolation.

Epidemics such as viral haemorrhagic fevers, severe acute respiratory syndrome, Middle East respiratory syndrome coronavirus or yet unknown ones have few chances of disappearing. Globalization, worldwide travel, climate change, social conflicts and wars, among others, are likely to favor the emergence of epidemics. Preparedness of hospitals to prevent the spread of these outbreaks is among the prioritized political programmes of many countries. The EuroNHID network has in the past drawn a map of features and equipment of hospitals across Europe to take care of highly contagious patients. We update the data regarding isolation capabilities and recommendations, with an emphasis on Mediterranean countries.

Occupational transmission of an Orthopoxvirus infection during an outbreak in a colony of Macaca tonkeana in Lazio Region, Italy, 2015.

Orthopoxviruses spill over from animal reservoirs to accidental hosts, sometimes causing human infections. We describe the surveillance and infection control measures undertaken during an outbreak due to an Orthopoxvirus occurred in January 2015 in a colony of Macaca tonkeana in the province of Rieti, Latio, Italy, which caused a human asymptomatic infection. According to the epidemiological investigation, the human transmission occurred after an unprotected exposure. The contacts among wild, captive and domestic animals and humans, together with decreased immunity against Orthopoxviruses in the community, may put animal handlers at risk of infection, especially after the cessation of smallpox vaccination. To reduce these threats, standard precautions including respiratory hygiene and transmission-based precautions should be carefully applied also in veterinary medicine.

A curriculum for training healthcare workers in the management of highly infectious diseases.

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.

Brucellosis with erythema nodosum-like manifestations diagnosed by isolated positivity of the ELISA test for anti-Brucella IgM.

Brucellosis is endemic in the Mediterranean area. In spite of the false negative results, the standard agglutination test remains the routine test for the diagnosis of brucellosis in southern Italy. We present a case of a patient with undulant fever and erythema nodosum-like skin lesions, with negative serum agglutination test, but isolated positivity of the ELISA test for anti-Brucella IgM. A diagnosis of brucellosis for this patient was supported by the anamnestic and clinical data, and by the response to therapy. This case and a review of the literature urge us to consider the ELISA test indispensable for the serological diagnosis of brucellosis.

Outbreak of cutaneous larva migrans in Naples, southern Italy.

An outbreak of cutaneous larva migrans occurring in Naples, southern Italy, and involving 6 people is described. The infection was contracted in the area of Naples, through contact with material for dried floral arrangements most probably contaminated with dog or cat faeces. The factors that contributed to creating ideal conditions for the development and spread of this infection in this area are discussed.

Infection control practices in facilities for highly infectious diseases across Europe.

BACKGROUND: The management of patients with highly infectious diseases (HIDs) is a challenge for healthcare provision requiring a high level of care without compromising the safety of other patients and healthcare workers. AIM: To study the infection control practice in isolation facilities participating in the European Network for Highly Infectious Diseases (EuroNHID) project. METHODS: A survey was conducted during 2009 of 48 isolation facilities caring for patients with HIDs in 16 European countries. Checklists and standard evaluation forms were used to collect and interpret data on hand hygiene, routine hygiene and disinfection, and waste management. FINDINGS: Forty percent of HIDs had no non-hand-operated sinks or alcohol-based antiseptic distributors, while 27% did not have procedures for routine hygiene, final disinfection, or safe discarding of non-disposable objects or equipment. There was considerable variation in the management of waste and in the training of housekeeping personnel. EuroNHID has developed recommendations for hand hygiene, disinfection, routine hygiene, and waste management. CONCLUSIONS: Most aspects of hand hygiene, routine hygiene and disinfection, and waste management were considered at least partially adequate in the majority of European isolation facilities dedicated for the care of patients with HIDs. But considerable variability was observed, with management of waste and training of housekeeping personnel being generally less satisfactory.

Facing the threat of highly infectious diseases in Europe: the need for a networking approach.

In recent years emerging and re-emerging infections, as well as the risk of bioterrorist events, have attracted increasing attention from health authorities because of the epidemic potential that renders some of them a real public health challenge. These highly infectious diseases (HIDs) are occurring more and more frequently in Europe, and despite the many initiatives in place to face them, many unsolved problems remain, and coordinated efforts for dealing with HIDs appear mandatory. Whereas uncoordinated measures would lead to only partial and poor responses to these emerging threats, networking represents a valuable approach to these diseases, in order to: (i) ensure a rapid and effective response; (ii) stimulate complementarity and prevent duplication; (iii) promote international cooperation, exchange of experience, good practice and protocols; and (iv) support the less prepared countries in the European Community.

EuroNHID checklists for the assessment of high-level isolation units and referral centres for highly infectious diseases: results from the pilot phase of a European survey.

Healthcare settings have been identified as preferential for the transmission of many agents causing highly infectious diseases (HIDs). Infection control procedures strongly reduce the risk of transmission of HIDs in hospital settings, when adequately applied. The main objective of the European Network for Highly Infectious Diseases (EuroNHID), a network co-funded by the European Commission, is to assess the current capabilities for dealing with HIDs in Europe, specifically in the context of infection control and healthcare worker (HCW) safety, through conducting an on-the-field survey of high-level isolation units (HLIUs)/referral centres for the management of HIDs in participating countries. During the first year of the project's activities, specifically designed, evidence-based checklists were developed. This review introduces the EuroNHID checklists as a standard tool for the assessment of hospital capabilities concerning infection control and HCW safety in the management of patients with HIDs, and presents preliminary results from five HLIUs.

Isolation rooms for highly infectious diseases: an inventory of capabilities in European countries.

Isolation of patients with highly infectious diseases (HIDs) in hospital rooms with adequate technical facilities is essential to reduce the risk of spreading disease. The European Network for Infectious Diseases (EUNID), a project co-funded by European Commission and involving 16 European Union member states, performed an inventory of high level isolation rooms (HIRs, hospital rooms with negative pressure and anteroom). In participating countries, HIRs are available in at least 211 hospitals, with at least 1789 hospital beds. The adequacy of this number is not known and will depend on prevailing circumstances. Sporadic HID cases can be managed in the available HIRs. HIRs could also have a role in the initial phases of an influenza pandemic. However, large outbreaks due to natural or to bioterrorist events will need management strategies involving healthcare facilities other than HIRs.
