A 2-year analysis of specimens among aircrew personnel in Southeast Asia is reported. Stool specimens were examined for intestinal parasites and enteric bacteria, blood smears for blood parasites, and sera tested for transaminases (SGOT) and antibodies to Entamoeba histolytica, Toxoplasma gondii, Chikungunya and Japanese encephalitis viruses, Rickettsia tsutsugamushi, Leptospira sp. and Pseudomonas pseudomallei. One to four specimens each were obtained from 537 adult males and 20 females. There were 56 subjects with intestinal parasites as follows: Giardia lamblia (3.8%), Endolimax nana (2.6%), Entamoeba histolytica (1.4%), Entamoeba hartmanni (0.9%), Entamoeba coli (0.7%), Trichiuris trichiura (1.7%), Ascaris lumbricoides (1.4%), hookworm (0.9%), and Clonorchis sinensis (1.2%). Two individuals had malaria, Plasmodium vivax (0.6%). Pathogenic enteric bacteria were isolated from seven stool specimens; Shigella groups B and D (0.9%), Salmonella paratyphi (0.3%), and Arizona group (0.9%). Significantly elevated SGOT levels were found in 0.9% and antibodies to Japanese encephalitis virus in 1.5%, to Rickettsia tsutsugamushi in 1.2%, to Pseudomonas pseudomallei in 0.3%, to Entamoeba histolytica in 0.9% and to Toxoplasma gondii in 10.1%. No antibodies were found to Chikungunya virus or Leptospira sp.

In Germany, the last period of the Second World War and the following years were characterized by deficiencies of hygiene which had not occurred previously in Middle Europe during the 20th century. There were focuses of typhus, typhoid fever, tuberculosis, diphtheria, scarlet fever, and meningitis. Insufficiencies in the removal of faeces caused high incidences of shigellosis, hepatitis A, and ascariasis. As a result of insufficient body care, many people were infested with fleas, lice and scabies. The migration of large proportions of the population resulted in an increasing prevalence of syphilis an gonorrhea. As the population resettled, the first steps towards reorganization of public health could be done. The spread of typhoid fever was controlled by drinking-water disinfection with chlorine, repair of sewage systems, and patient isolation. The application of DDT helped to reduce scabies and pediculosis, resulting in decreasing typhus risks. During the first two decades after the war, there was a steady decrease of the incidence of infectious diseases. The reconstruction of the towns resulted in improved housing conditions and a decreasing number of persons per housing area, reducing the intensity of physical contacts of the inhabitants with each other. The nutrition and clothing situation of the population improved, which, in addition to a general rise of the standards of hygiene, brought about an increase of the individual resistance to infection. A further reduction of sporadic and epidemic outbreaks of infectious diseases was achieved by the introduction of chemotherapy and antibiotics. Increasing prosperity was accompanied by new problems of hygiene. Infectious diseases almost eradicated in West Germany, were imported by air travellers. Ten imported cases of smallpox were reported between 1957 and 1972, eight of which originated from Southeast Asia. Malaria, imported by German and foreign soldiers, had not been uncommon after the end of the war but had been easy to control by insecticides and antimalarials. As tourism expanded, a new wave of imported malaria cases was reported. In West Germany there is, however, no more spread of the disease under present conditions, cholera caused similar problems. The 1961 cholera epidemic started in Southeast Asia and caused minor outbreaks in Mediterranean countries like Italy and Spain. A significant spread of the disease throughout Europe was prevented by generally high standards of drinking water and sewage treatment. Sporadic cases of typhoid fever were imported from countries with low standards of hygiene.(ABSTRACT TRUNCATED AT 400 WORDS)

The mean annual rate of decline of the probability of dying 5 years of age in developing countries is 2.5%. Nevertheless disease accounts for a considerable proportion of premature deaths. The leading causes of death in these countries, in order, include respiratory disease, diseases of the circulatory system, low birth weight, diarrhea, measles, injuries, malnutrition, and neoplasms. These conditions represent diseases of poverty and affluence. Respiratory infections are common among 5-year old children and cause a high proportion of child deaths. Circulatory diseases tend to be limited to adults. Control of hypertension, diet, smoking prevention, and exercise can prevent circulatory diseases. The risk of dying in infancy and childhood and of developmental disabilities is higher among low birth weight infants than those who weigh 2500 gm. In Bangladesh, 50% of infants weight 2500 gm. Low birth weight is the underlying cause of death for many infants who die of respiratory infections and diarrhea. Oral rehydration can successfully treat most diarrhea cases. Malnutrition and diarrhea tend to occur together and feed off each other. In fact malnourished people are more susceptible to all infections. Malnourished children suffer from disabilities in development and growth. The greatest sufferers of measles are infants and malnourished children. Immunization of all =or 9-month old infants would eradicate measles. Children and young adults are at the highest risk of injuries. Lung cancer is on the rise in developing countries due to the increase of tobacco smoking. Various means of controlling malaria are use of mosquito nets, antimalarial drugs, reduction of mosquito breeding places, and pesticides. The new infectious disease, AIDS, has emerged as a considerable health problem in developing countries. High priority research areas are vaccines for Streptococcus pneumonia, Plasmodium app., rotavirus, Salmonella typhi (Ty21a), and Shigella spp.

In 1979, British laboratories participating in the American of Clinical Pathologists' survey reported five cases of tuberculosis, four of chickenpox, four of salmonellosis or shigellosis, one malaria, and one hepatitis A infection. Microbiology workers were most affected, but at least six infections were not attributable to work. All cases recovered.

There are social, economic and entomological problems with conventional insecticidal spraying methods for vector control. There is therefore interest in alternative technologies, especially the impregnation of bed nets with pyrethroid insecticides against malaria vectors. This method is cheap, socially acceptable and effective where bed nets are already widely used and where malaria transmission is not very intense. In holoendemic areas, and where people consider bed nets unaffordable, there are still unanswered questions. Whether pyrethroid resistance will be selected in anophelines also deserves more attention than it has so far attracted. Where Culex mosquitoes breed in confined sites such as pit latrines, the application of floating layers of polystyrene beads is a long-lasting and effective control method. There is increasing evidence that house flies are important agents in the mechanical transmission of diarrhoea due to Shigella. Simple fly traps can be an effective way of controlling house fly populations and this deserves comprehensive testing in tropical countries.

Researchers prospectively studied 264 children aged less than 5 years with diarrhea who were admitted to the Bouake Regional Hospital Center in the Ivory Coast between June 10 and August 11, 1991, to identify clinical disorders associated with severe diarrhea. They compared data on the 196 children with non-severe diarrhea with data on 68 children with severe diarrhea. All but three of the children were breast fed. The severely ill children were more likely than the non-severely ill children to have dehydration (45% vs. 11%; p 0.01), severe wasting (22% vs. 7%; p 0.01), anemia (29% vs. 13%; p = 0.01), bacteremia (26% vs. 9%; p 0.01), and malarial parasitemia (27% vs. 14%; p = 0.02). 68% of the blood isolates had nontyphoidal Salmonella spp. 6% of children had HIV-1 or HIV-2 infection. The most common pathogens in the stool specimens were rotavirus (41 cases), Campylobacter jejuni (22), Shigella spp. (21), and Salmonella spp (10). These findings indicate a need for a more comprehensive approach to assessment and management of children with diarrhea that secures immediate recognition of bacteremia, anemia, wasting, malaria, and dehydration.

From June to October 1995, the U.S. Army's 86th Combat Support Hospital was deployed in Haiti in support of the United Nations peacekeeping mission. The hospital's mission was to provide comprehensive health care to United Nations military and civilian personnel in Haiti. The hospital's laboratory, with microbiological and parasitological capability, was a critical asset in light of the infectious disease threats in Haiti. A total of 356 microbiological (5.4%) and 887 parasitological (13.4%) tests were performed, out of a total of 6628 laboratory tests. One finding was the discovery of antibiotic-resistant urinary isolates of Escherichia coli. These were from community-acquired infections and included strains resistant to ampicillin (6/15), trimethoprim+sulfamethoxazole (6/15), and ciprofloxacin (2/15). Ampicillin (8/15) and trimethoprim+sulfamethoxazole (3/15) resistance was also noted in Shigella spp. However, no chloroquine-resistant strains of malaria were encountered. Dengue virus, also mosquito borne, was a major pathogen. Antimicrobial-resistant nosocomial pathogens were also encountered. Deployed laboratories should be able to determine antimicrobial susceptibility and perform microbial identification to guide clinical management, conduct medical surveillance, and detect emerging resistance.

International movement of individuals, populations, and products is one of the major factors associated with the emergence and reemergence of infectious diseases as the pace of global travel and commerce increases rapidly. Travel can be associated with disease emergence because (1) the disease arises in an area of heavy tourism, (2) tourists may be at heightened risk because of their activities, or (3) because they can act as vectors to transport the agent to new areas. Examples of recently recognized diseases with relationship to travel include HIV, Legionnaire's disease, cyclosporiasis, Vibrio cholerae O139 Bengal, hantavirus, and variant Creutzfeldt-Jacob disease. Reemerging diseases include dengue fever, malaria, cholera, schistosomiasis, leptospirosis, and viral hemorrhagic fevers. In addition, tuberculosis, drug-resistant shigellosis, and cholera have been major concerns in refugee and migrant populations. Because of the unique role of travel in emerging infections, efforts are underway to address this factor by agencies such as the CDC, WHO, the International Society of Travel Medicine, and the travel industry.

International air traffic has increased the risk of importation of infectious diseases to Norway. We have used notification data and a theoretical framework to assess the risk of importation and subsequent disemination of serious infectious diseases in Norway. Every year, a few cases of these diseases are imported to Norway, especially malaria, shigellosis and typhoid fever. A few secondary cases of enteric diseases may occur, but epidemics are unlikely. Counselling and immunisation of Norwegians going abroad is the first step in prevention. Secondly, health services all over the country should be able to diagnose imported diseases early and institute infection control measures. However, there is no need for concentrating resources for disease control at international airports in Norway.

The FIFA World Cup 2002 Korea/Japan, which will be held during May 31 through June 30, 2002, is a mass-gathering and high-profile event. The Ministry of Transport announced that approximately 430,000 people visit Japan for the event. We estimated the incidence of major imported infections using data from the national epidemiological surveillance of infectious diseases and the statistics of immigration. Estimated incidences are 5.88 (shigellosis), 3.41 (malaria), 1.40 (typhoid/paratyphoid fever), 0.42 (cholera), and 0.0032 (meningococcal meningitis). The incidence for viral hemorrhagic fever was estimated 0.0018 under assumption that "it correlates with the malaria incidence from Africa" and that "the incidence occurs every 15 years". These results indicate little possibility of remarkable increase of exotic infections during the event. These incidences, however, may occur in the rural prefectures where few cases are reported. It is highly needed to strengthen surveillance and educate physicians and public health experts especially for malaria cases.
