Among the most important responsibilities of a hospital's employees' health service is the prevention or prompt identification of infectious illnesses among staff members. Infections constitute a major health hazard of hospital employment and, both intrinsically or as a consequence of subsequent transmission to hospitalized patients, can have devastating consequences. The risks associated with tuberculosis, viral hepatitis, rubella, herpes, meningococcal disease, and scabies are generally acknowledged and methods of control have been suggested. In addition, immunizations against diphtheria and influenza have been advised under certain circumstances. Respiratory syncytial virus and pertussis probably account for some upper respiratory tract illnesses among personnel and may lead to serious morbidity in pediatric patients. Laboratory-acquired infections can be diverse and exotic. Control measures should include surveillance, appropriate immunizations, epidemiologic investigation coordinated with infection control, antibiotic prophylaxis when indicated and environmental safeguards.

The experienced morphologist can be extremely helpful to the clinician by virtue of his or her ability to distinguish among the various subtypes of reactive lymphocytoses. An awareness on the part of the clinician as to the nuances of subclassification may lead to earlier diagnosis of a disease process. Broadly, proliferations of normal lymphocytes point to infectious lymphocytosis or Bordetella pertussis infection. Proliferations of atypical lymphocytes, especially when minimum diagnostic criteria are present or there are four or more Downey III forms per 100 WBCs, suggest infectious mononucleosis. Proliferations of immunoblasts reflect hypersensitivity reactions to drugs or autoimmune disease. Proliferations of proplasmacytes or plasma cells favor viral hepatitis, drug reactions (notably to sulfa drugs), or rubella. Quantitative data may help refine the morphologic implications. Cumulatively, qualitative and quantitative data should lead the clinician to a judicious selection of confirmatory serologic tests and hence to earlier diagnosis.

The timely facilitation of immunologic (immunoglobulin or vaccine) or antimicrobial prophylaxis is used in individuals who have been exposed to certain infectious diseases. Such methodology has been shown to be helpful in infections such as viral hepatitis types A and B, measles, varicella, rabies, and tuberculosis. The data supporting such use in rubella and mumps are not strong and information is still needed in hepatitis C, human immunodeficiency virus, and Lyme borreliosis. This article reviews postexposure prophylaxis in these situations. Preventive strategies for meningococcal disease, group A streptococcus, tetanus, diphtheria, and pertussis are discussed elsewhere in this issue.

A systematic analysis, including retrospective test by means of correlation analysis and extrapolation test was carried out to demonstrate a new hypothesis named Z-D phenomenon which states that the skew of a seasonal case distribution curve of an infectious disease may appear to be the omen of its epidemic trend in the following year. A total number of 353 data sets belong to 17 notifiable infectious diseases in 29 provinces and the whole nation were chosen. Data from retrospective test showed that 91.2% (322/353) of the correlation coefficients of between the skew of the seasonal distribution curve of the previous year and the morbidity variation of its following year were negative. The extrapolation test showed that 68.1% (203/295) of the data sets accorded with the actually epidemic situation at the level of r < -0.5. The results proved the existence of Z-D phenomenon may serve as an indicator for the purpose of forecasting. Using this systematic analysis, we found that Z-D phenomenon was more expressive in viral hepatitis, pertussis, epidemic cerebrospinal meningitis and scarlet fever than in other diseases.

In 1998, a series of regional cluster surveys (the ICONA Study) was conducted simultaneously in 19 out of the 20 regions in Italy to estimate the mandatory immunization coverage of children aged 12-24 months with oral poliovirus (OPV), diphtheria-tetanus (DT) and viral hepatitis B (HBV) vaccines, as well as optional immunization coverage with pertussis, measles and Haemophilus influenzae b (Hib) vaccines. The study children were born in 1996 and selected from birth registries using the Expanded Programme of Immunization (EPI) cluster sampling technique. Interviews with parents were conducted to determine each child's immunization status and the reasons for any missed or delayed vaccinations. The study population comprised 4310 children aged 12-24 months. Coverage for both mandatory and optional vaccinations differed by region. The overall coverage for mandatory vaccines (OPV, DT and HBV) exceeded 94%, but only 79% had been vaccinated in accord with the recommended schedule (i.e. during the first year of life). Immunization coverage for pertussis increased from 40% (1993 survey) to 88%, but measles coverage (56%) remained inadequate for controlling the disease; Hib coverage was 20%. These results confirm that in Italy the coverage of only mandatory immunizations is satisfactory. Pertussis immunization coverage has improved dramatically since the introduction of acellular vaccines. A greater effort to educate parents and physicians is still needed to improve the coverage of optional vaccinations in all regions.

Alcohol consumption and viral hepatitis infection synergistically accelerate liver injury, but the underlying mechanism is not fully understood. Here we have examined the effects of ethanol on hepatitis B protein X (HBX)- or hepatitis C core protein (HCV core protein)-mediated activation of NF-kappaB, a critical signal in hepatic injury, regeneration, and tumor transformation. Acute ethanol or acetaldehyde exposure potentiates HBX or HCV core protein activation of NF-kappaB in primary mouse hepatocytes. Such potentiation can be abolished by blocking ethanol metabolism or overexpression of dominant negative NF-kappaB-inducing kinase (NIK), IkappaB kinase (IKK), or IkappaB. Moreover, pertussis toxin attenuates NF-kappaB activation induced by acetaldehyde but not by HBX or HCV core protein, whereas HBX or HCV core protein-mediated activation of NF-kappaB is abolished completely in tumor necrosis factor a receptor 1 (TNFR1) (-/-) hepatocytes. Finally, chronic ethanol consumption induces hepatic CYP2E1 protein expression and potentiates HBX or HCV core protein activation of NF-kappaB in the liver. These findings suggest that ethanol activates hepatic NF-kappaB via its metabolism and that HBX or HCV core protein activates hepatic NF-kappaB via TNFR1. With the essential role of TNFR1 in alcoholic liver injury, targeting TNFR1 by hepatitis viral proteins could contribute to cooperative effects of alcohol consumption and viral hepatitis on liver disease.

The status and likely impact of existing and potential new combined hepatitis B vaccines were broadly considered at the Viral Hepatitis Prevention Board (VHPB) meeting in Malta, October 2001. The currently available and/or licensed combined hepatitis B vaccines in Europe and the prospects for further such vaccines were reviewed. Data on the safety, immunogenicity, and European licensing status and availability of haxavalent vaccines combining hepatitis B (HepB), Haemophilus influenza type b (Hib), diphtheria, tetanus, and pertussis (acellular) (DTPa), and inactivated poliovirus (IPV) antigens were presented. Finally, the impact of the availability of combined hepatitis B vaccines on hepatitis B immunisation programmes in Europe were examined and the added value of combined hepatitis B vaccines globally was estimated.

In 2001 surveillance system of infectious diseases in Poland remained unchanged. New cases of infectious diseases were recorded in 103 positions including intoxications. Tuberculosis and sexually transmitted infections were registered in separate systems. Influenza was the most frequently reported infectious disease with 576,449 cases, 63.9% less then in the previous year. The next most numerous were foodborne infections, which were reported in 24,393 cases, including 19,788 cases of infections caused by Salmonella sp. An increase in incidence was observed in the following diseases: viral hepatitis type A, rubella, measles and pertussis. Also the number of recorded cases of Lyme boreliosis and tickborne encephalitis were higher then in 2000. Incidence of AIDS remained within the range recorded during the last few years. In 2001 further drop in incidence of viral hepatitis type B was observed reaching the level of 6.2 per 100,000. It was the result of implemented comprehensive program of prophylactic measures, which brought incidence of this disease from the highest in Europe down to the level close to European average. Infectious diseases contributed to 0.75% of deaths. The most frequent cause of death among infectious diseases was tuberculosis and its sequels (1,061 cases). 13 cases of death due to tuberculosis occurred in people below 30 years of age.

Vaccine-preventable diseases (VPDs) are costly at both the individual and societal levels. The most common VPDs recorded in travellers are enteric (typhoid or paratyphoid B) fever, acute viral hepatitis, influenza, varicella, measles, pertussis and bacterial meningitis. Travellers suffering from VPDs are frequently hospitalized, illustrating the point that VPDs are serious and expensive. Many travellers are not properly immunized before travel. In addition to individual consequences, VPDs can have public-health consequences if they are introduced or re-introduced by infected travellers returning to areas with susceptible populations. The international spread of poliomyelitis, Neisseria meningitidis serogroup W135 meningococcal infections, measles and influenza provides strong evidence of the role of international travel in the globalization of VPDs. The surveillance of the emergence, re-emergence or spread of VPDs is essential to adapt pre-travel advice and the responses to the VPD.
