Occupational infections in farm workers
This paper deals with occupational infections which can cause disease and disability in agricultural workers. Prevention and control methods discussed include: personal protective equipment; educational efforts; workplace revisions and engineering controls; animal control measures, such as vaccines and antibiotics. To the physician treating a farmer with various symptoms the paper offers checklists of questions concerning work activities, exposures, and medical history. The symptoms, diagnostic tests, treatment, and prevention and control of the 11 most common agricultural infections are presented: anthrax; ascariasis; brucellosis; viral encephalitis; leptospirosis; Q fever; rabies; Rocky Mountain Spotted Fever; staphylococcal infections; tetanus; tularaemia.

Respiratory risks associated with agriculture
This literature survey focuses on epidemiological evidence of respiratory disease among agricultural workers. Agricultural processes and the farm environment generate dusts, moulds, pollens, toxins, and gases that are potential respiratory irritants or health risks. Acquired sensitivity results in allergic reactions, with symptoms such as cough, dyspnoea, fever, malaise, myalgia, arthralgia, and weight loss. Respiratory disease can become disabling and can lead to asthma and pulmonary fibrosis. Further studies are suggested.

Mycobacterium bovis infection in human beings in contact with elk (Cervus elaphus) in Alberta, Canada
Following an epizootic of M. bovis infection in domesticated elk, in Alberta, Canada, 466 human contacts of elk herds were identified, of whom 394 were assessed. Of 81 contacts whom were tuberculin skin-test positive, 50 had been in contact with culture-positive animals. The mode of transmission of M. bovis from these farm animals to man is likely to be aerosolisation of infected particles. Because of the apparent susceptibility of farmed Cervidae (deer) to M. bovis infection, and the evidence of spread to man, control measures to prevent human infection should be developed.

Reversal of non-responders and post-exposure prophylaxis by intradermal hepatitis B vaccination in Japanese medical personnel
Thirty-one Japanese non-responders to subcutaneous hepatitis B vaccination and 15 medical personnel who were accidentally exposed to specimens positive for hepatitis B e antigen and were given hepatitis B immunoglobin were intradermally immunised with hepatitis B vaccine every 2 weeks until delayed type hypersensitivity skin reaction to hepatitis B surface antigen (HBsAg) became positive. One year later, 74% of the non-responders still had sufficiently high levels of anti-HBsAg, while for the exposed personnel protection was 100%. Intradermal hepatitis B vaccination is therefore seen to be useful in reversing non-responsiveness to hepatitis B surface antigen and for prophylaxis after exposure.

Universal precautions and mortuary practitioners: Influence on practices and risk of occupationally acquired infection
Embalming, the most common funeral practice in North America, may expose the embalmer to infectious diseases and blood. 860 morticians in the US and Canada were surveyed in 1988 to estimate the incidence of self-reported occupational contact with blood and infectious disease, assess morticians' knowledge of acquired immunodeficiency syndrome (AIDS), determine their adherence to universal precautions, and identify predictors of practices designed to reduce risk of occupational exposure to infections. Of 539 (63%) respondents, 212 (39%) reported needle-stick injuries in the past 12 months, and 15 (3%) reported percutaneous exposures to HIV-contaminated blood. Those rating the risk of occupationally acquired human immunodeficiency virus infection as very high or high (194/539 [36%]) were more likely to decline funerals of bodies with antemortem diagnosis of AIDS (59/194 [30%]) and/or to charge more for such funerals (133/194 [69%]) than those who rated the risk as low to moderate (31/345 [9%], 174/345 [51%]).

Vaccine choice and program participation rates when two hepatitis B vaccines are offered
Participation rates of health care workers in voluntary free hepatitis B virus immunisation programmes are 35% to 40%. University teaching hospital employees at risk for hepatitis B virus and presenting for immunisation were surveyed as to vaccine preference. Both plasma-derived and recombinant hepatitis B virus vaccines were available. During a 10-month period, 173 health care workers enrolled in the study. One hundred seventeen received recombinant vaccine, and 56 received plasma-derived vaccine; 66 were immunised post-exposure. Concern of a relationship of human immunodeficiency virus to hepatitis B virus plasma-derived vaccine was acknowledged by a small number of health care workers as important in vaccine selection. Recombinant hepatitis B virus vaccine rapidly and substantially supplanted plasma-derived vaccine but did not increase programme participation. It is suspected that mandatory immunisation or proof of immunity will be necessary if hepatitis B virus protection rates in health care workers are to improve.

Work injuries and exposures in children and young adults: Review and recommendations for action
Child labour is endemic in poor countries but also occurs in affluent countries. Little information has been available on injuries, disease, and effects on growth and development in the tens of millions of children at risk. Preventive and control measures are eliminating the gross abuses, tracing and banning hazardous exposures to toxic agents, eliminating risks of injuries and ergonomic strain, providing health services for working children through the primary health care network, and developing international fail-safe design standards for tools and work systems, if these children must work. There is a need to train public health professionals, paediatricians, and maternal and child health care personnel in carrying out simple descriptive epidemiological studies and setting up interventive programmes. Eliminating the worst conditions and controlling hazards where there is no imminent alternative to child labour are suggested as the basis for protecting children who are forced to work.

Benefit-cost analysis of hepatitis B vaccine programs for occupationally exposed workers
The Occupational Safety and Health Administration of the US proposed a vaccination programme for workers exposed to the hepatitis B virus 12 or more times per year. A benefit-cost analysis was performed of the proposed regulation and of an expanded rule that covers all at-risk workers, regardless of the number of exposures. The annualised cost of the proposed vaccination programme is estimated at USD 60.4 million. The financial benefit of the programme was estimated using two methods. The first estimates the avoided cost of medical care, prophylaxis, and lost productivity at USD 124 million annually. The second approach includes the value of avoided pain and suffering from hepatitis B, thus increasing the total dollar benefit to USD 679 million. Although both methods indicate that benefits are greater than programme costs, the valuation of avoided pain and suffering substantially increases net benefits. Furthermore, provision of the vaccine to all exposed workers is cost-effective if one or more cases of hepatitis B are avoided per 6500 workers annually.

Aspects of occupational health in the sugar cane industry
Workers in developing countries face as many, if not more, work-related health problems as their counterparts in industrialised nations. This paper concentrates on occupational health problems in the sugar industry, which exists in 40 countries, mostly in the Third World. Sugar cane workers have a high level of occupational accidents and are exposed to the high toxicity of pesticides. They may also have an increased risk of lung cancer, possibly mesothelioma. Bagassosis is also a problem specific to the industry as it may follow exposure to bagasse (a by-product of sugar cane). The workers may also be affected by chronic infections which reduce their productivity. The legal framework for their protection is often inadequate. In conclusion, areas of future research are suggested.

Attitudes and behaviors of medical technologists as a result of AIDS
To determine the influence of AIDS on the attitudes and behaviours of medical technologists, a survey was taken which shows that one quarter are considering leaving the profession. Individuals who plan to stay in the profession are less fearful of AIDS, more satisfied with the policies their organisations have established regarding the disease, and less willing to associate a declining employment situation with it. Improvement in safe laboratory practices is present in both groups, but the individuals considering a move out of the field exhibit the largest change. A surprising result is that fear of AIDS is not related to or only weakly associated with traditional demographic and occupational variables, suggesting that other more complex factors are influencing the views and work habits of medical technologists as a result of AIDS.

Research in occupational health: the UK National Health Service
This article discusses the scope of research to be carried out in the UK National Health Service which, if allied to occupational health practice, might have important direct or indirect benefits for patient care. General research topics that await further study include: health inequalities amongst health care workers, job stress, back problems, pregnancy, and infection risks from blood. Topical specific hazards include gluteraldehyde, cytotoxic drugs, nuclear magnetic resonance imaging, and implications of new technology in surgery. The co-ordination of databases across different district health authorities would be very useful for epidemiological research, the delivery of OSH services and the development of vaccination strategies.

Knowledge and attitude of health care workers about AIDS and HIV infection before and after distribution of an education booklet
Hospital workers (509) in a health authority were surveyed, and asked if they were in contact with HIV positive or AIDS patients, about their perception of risk and their knowledge about attitudes towards HIV and AIDS problems at work. Following the first survey, an information booklet was distributed to all health authority staff and after distribution, 232 staff were surveyed again. In this group (the follow-up group), there was a reduction in perceived risk, and improvement in the level of knowledge and in attitudes, and a reduction in the desire for further information. The group who initially had the least level of knowledge and most unfavourable attitudes (non-clinical workers) were the group who improved most.

Prevalence of antibodies to hepatitis B core antigen (anti-HBc) in Buenos Aires hospital personnel
Prevalencia del anticuerpo contra el antígeno central del virus de la hepatitis B (anti-HBc) en personal hospitalario de Buenos Aires [in Spanish]
A group of 1,479 employees in various hospitals in Buenos Aires (Argentina) were tested for antibodies to hepatitis B core antigen, in order to identify those who should be vaccinated against this disease. 85.5% of them were working in services where the risk of infection was high. The results showed that 85.0% of the individuals did not have anti-HBc and thus were considered candidates for vaccination. The antibody was present in 15.0% of the workers. The prevalence of anti-HBc increased with age and with length of service, and it was greater in laboratory technicians, nurses and those in high-risk services. A total of 23 carriers of hepatitis B surface antigen (AgHBs) were identified. It is argued that the high prevalence of anti-HBc in laboratory technicians, nurses and nurses' aides might justify their systematic vaccination. Summary in English.

Prevention of hepatitis B in public hospitals in Paris - Results of 7 years of vaccination by occupational physicians
Prévention de l'hépatite virale B à l'Assistance Publique - Hôpitaux de Paris - Bilan de 7 ans de vaccination par les médecins du travail [in French]
The results of a questionnaire survey addressed to all occupational health departments of the Paris Public Health Department seven years after the beginning of a vaccination campaign against hepatitis B showed a significantly positive outcome. On 15 February 1989, in 32 of the 45 departments questioned, 45% of the personnel at risk (14,528/32,034) were either completely vaccinated (32%) or in the course of being vaccinated (13%). Vaccination protection varied greatly from hospital to hospital, between departments, and between professional categories. The number of cases of occupational viral hepatitis dropped from 222 in 1980 to 37 in 1988, of which only 16 were hepatitis B.

Blood contact incidents among health care personnel
Incidenter med blodkontakt bland sjukvårdspersonal [in Swedish]
Among some 2,000 persons in 37 departments of five hospitals in the region of Stockholm, Sweden, there were 465 reported cases of blood contact: 65 cases of contact with puncture wounds or cuts ('injection' cases), 57 with mucous membranes or injured skin and 343 with intact skin. Midwives had the highest frequency of incidents (389 per 100 persons), followed by physicians with 217 and nurses with 146 (laboratory and dental personnel were also included in the study). Injection cases were most frequent for the physicians (34/100 persons), followed by the nurses (27) and midwives (24). A follow-up study of 522 of the initial group showed that incidents were under-reported. Interviews with representative subjects gave details on the circumstances of the incidents.

The risk of infection with work in water purification plants (biological treatment) is the subject of numerous investigations. While the theoretical risk may be disturbing, the actual risk may be less clear, as shown by this literature survey, based on observations made by a group of industrial physicians. The principles of waste water treatment are first explained, followed by a description of the microbiological risks in biological-treatment purification plants: theoretical risks, routes of contamination, actual risks (digestive, respiratory and skin diseases, leptospirosis, sewer workers' syndrome). A summary of the data collected is presented, along with preventive measures concerning all types of risks found in purification plants. An annex shows a medical follow-up sheet.

The changing epidemiology of hepatitis B in the United States: Need for alternative vaccination strategies
A programme of intensive surveillance for acute viral hepatitis was carried out from 1981 through 1988 in 4 "sentinel counties" in the USA. The overall incidence of hepatitis B remained relatively constant throughout the study period, although disease transmission patterns changed significantly. There was a significant decline in the numbers of health care workers (75%) reported with hepatitis B, probably as a direct result of immunisation with hepatitis B vaccine and wider implementation of universal blood precautions.

Hepatitis B infection hazard among sewer and sewage plant workers
Hepatitis-B-Infektionsgefährdung bei Kanal- und Klärwerksarbeitern [in German]
A higher number of persons (24) with hepatitis B virus infection was found among 93 sewer maintenance workers than among hospital personnel. Of 84 workers in sewage treatment plants 11 were found to be infected. The high infection rate among sewer maintenance workers is blamed on contact with infectious waste water and sewage sludge and on the high rate of hand injuries. It is recommended to duly inform this specific category of workers of the hazards they have to face and to offer them hepatitis B vaccination.

CIS 91-1363 Occupational infection among anaesthetists
Short review of the risks for anaesthetists of exposure to blood and body fluids carrying infectious organisms, in particular hepatitis B virus (HBV) and human immunodeficiency virus (HIV). The fact that anaesthetists have more HBV markers than the general population suggests that occupational infection does occur. Immunisation against hepatitis B gives a high level of protection. Although there have been no fully documented cases of accidental HIV infection among anaesthetists, such incidents have been reported in other health care workers. There is no protective vaccine against HIV and the wearing of gloves is advised as a minimum protective measure.

Infection risks in hospital staff from blood: hazardous injury rates and acceptance of hepatitis B immunization
A questionnaire survey of 1800 clinical health care staff was undertaken to determine hazardous injury rates and uptake of hepatitis B vaccination. The overall sharps injury rate was 116 injuries per 100 staff per year. Full-time doctors had the highest rates. Surgical procedures were the commonest cause of accidental injury (58 per cent) and 30 per cent of all sharps injuries were attributable to careless handling. Injuries caused by bites and scratches from patients occurred mainly in nurses in psychiatric and geriatric wards (115/100 staff per year). Twenty-four per cent of respondents had received a full course of hepatitis B vaccine and 51 per cent of the remainder were planning to have it. This survey reveals injury rates higher than those observed in previous reports, particularly in doctors, and shows a need for more information and advice about hepatitis B infection and vaccination to be targeted to health care workers at risk.

Hepatitis A - occupational risk for health service employees?
Die Hepatitis A - Arbeitsmedizinisches Risiko bei Beschäftigten im Gesundheitsdienst? [in German]
Analysis of 13 hepatitis A cases which occurred between 1979 and 1989 among personnel in a hospital in Freiburg, Germany, showed kitchen help to be a source of the disease. As a consequence, 1001 serum samples collected during routine check-up examinations of medical and hospital personnel were tested for anti-HAV. The percentage of anti-HAV positive was significantly higher among kitchen personnel in all age groups than among the general population. Therefore kitchen personnel should be a target of active hepatitis A immunisation.

Risk of hepatitis A infection among sewage workers
Hepatitis-A-Infektionsgefährdung bei Kanal- und Klärwerksarbeitern [in German]
Infection with hepatitis A virus (HAV) was studied among 93 sewerage workers and 84 workers in waste water treatment plants in Cologne, Germany. In comparison to the general population of the same age, HAV infection among young sewerage workers was 3-4 times higher. Anti-HAV antibodies were found in 35.7% of 21-30-year-old sewerage workers and in 85% of those aged 50 and above. Of the 84 workers in waste water treatment plants, 47 (56%) showed anti-HAV. Thus, sewerage workers are persons at risk for whom active vaccination should be practised.

CIS 91-321 Preventing Legionnaires' disease
Prevention of Legionnaires' disease centres on preventing the inhalation of water aerosols contaminated with the Legionella pneumophila bacteria. In order to prevent growth of the bacteria, water systems capable of generating aerosols when restarted should be derived and kept dry during a period of disuse, and air-cooled chillers should be used in preference to evaporative coding towers. Water supplies should be stored either below 20°C or above 55°C, and care should be taken to prevent stagnation of water. All storage cisterns should be protected against the ingress of plant and animal matter, and only approved fittings and materials should be used. Cleaning and routine maintenance should be scheduled.
