The international community has launched the Children's Vaccine Initiative, which has created the most ambitious grouping of public and private sector interests ever to tackle a global health issue. Developed by WHO, UNICEF, UNDP, the World Bank, and the Rockefeller Foundation, the initiative is the result of decisions taken at the World Summit for Children, held in New York in September 1990. During that meeting, world leaders requested greater resources for the development of new or better vaccines. The Children's Vaccine Initiative, says WHO Director-General Dr. Hiroshi Nakajima, will not only yield specific benefits in improving vaccines, it will also establish a process of collaboration between the public and private sectors, which will have far-reaching benefits in other areas. The new initiative comes on the heels of another international effort, the successful Expanded Program on Immunization, which in 1990 achieved its goal of immunizing 80% of the world's children against 6 major childhood diseases: poliomyelitis, measles, tuberculosis, diphtheria, pertussis, and tetanus. The new initiative will strive to develop vaccines against a wider spectrum of viral, bacterial, and parasitic diseases which cause mortality in children. These diseases include rotavirus infection, hepatitis A and E, dengue, Japanese encephalitis, acute respiratory diseases, meningococcal meningitis, diarrheal diseases, pneumococcal pneumonia, and malaria. The new initiative will also seek to improve existing vaccines, making them easier to administer and less painful and costly.

A prospective study using a Latex particle agglutination test for the detection of bacterial antigens in CSF has been carried out in 91 patients in Kamuzu Central Hospital, Malawi. The antigens sought were those of Streptococcus pneumoniae, Haemophilus influenzae b, Neisseria meningitidis B/E. coli K1, and Neisseria meningitidis A,C,Y,W 135. Forty-one patients had proven bacterial meningitis, two had tuberculous meningitis, 39 had cerebral malaria, four had aseptic meningitis and five had convulsions. The sensitivity and specificity of the tests (Str. pneumoniae, 88% and 100%, H. influenzae b, 87% and 96%; N. meningitidis A,C,Y,W 135, 100% and 100%; and N. meningitidis B, 100% and 98%) were as good as those reported from developed countries. Unlike in some other parts of Africa, group B meningococci seem to predominate in cases of meningococcal meningitis in Malawi.

Nearly 40 million journeys abroad were recorded from the Federal Republic of Germany last year. 60-70% of travellers going to southern countries seek medical advice for preventive measures, particularly in Public Health centres. Inquiries for vaccinations are prevalent. Current aspects of immunization against yellow fever, cholera, tetanus, polio, typhoid fever, hepatitis A, hepatitis B, rabies meningococcal meningitis, European tick-borne encephalitis, measles and tuberculosis are discussed. Finally, some remarks on malaria prevention, hygiene, health insurance and information services are given in brief.

Ethiopia is a country of 45 million people in northeast Africa. With a stagnant, agriculture-based economy and a per capita gross national product of $110 in 1984, it is one of the world's poorest nations. 70% of the children are mildly to severely malnourished, and 25.7% of children born alive die before the age of 5. Life expectancy is 41 years. The population is growing at the rate of 2.9%/year, but only 2% of the people use birth control. After the 1974 revolution, the socialist government nationalized land and created 20,000 peasant associations and kebeles (urban dwellers' associations), which are the units of local government. The government has set ambitious goals for development in all sectors, including health, but famine, near famine, forced resettlement programs, and civil war have prevented any real progress from being made. The government's approach to health care is based on an emphasis on primary health care and expansion of rural health services, but the Ministry of Health is allocated only 3.5% of the national budget. Ethiopia has 3 medical schools -- at Addis Ababa, Gondar, and the Jimma Institute of Health Sciences. Physicians are government employees but also engage in private practice. A major problem is that a large proportion of medical graduates emigrate. Ethiopia has 87 hospitals with 11,296 beds, which comes to 1 bed per 3734 people. There are 1949 health stations and 141 health centers, but many have no physician, and attrition among health workers is high due to lack of ministerial support. Health care is often dispensed legally or illegally by pharmacists. Overall, there is 1 physician for 57,876 people, but in the southwest and west central Ethiopia 1 physician serves between 200,000 and 300,000 people. In rural areas, where 90% of the population lives, 85% live at least 3 days by foot from a rural health unit. Immunization of 1-year olds against tuberculosis, diphtheria-pertussis-tetanus, poliomyelitis, and measles is 11, 6, 6, and 12% respectively. Infectious diseases dominate the medical scene in Ethiopia. In 1984, tuberculosis accounted for 11.2% of hospital admissions and 12.2% of deaths. The leading cause of childhood mortality in 1984 was diarrhea (45%). Malaria, trypanosomiasis, schistosomiasis, leishmaniasis, and meningococcal meningitis are endemic. Intestinal parasitism is rampant, and the nationwide prevalence of leprosy is 3/1000. Venereal diseases were the 9th most common cause of hospital outpatient visits in 1984, but AIDS is rare. The leading noninfectious diseases are rheumatic and syphilitic heart disease, hypertension, diabetes mellitus, hepatoma, and elephantiasis. Ethiopia has the highest number of cases of nonfilarial elephantiasis -- an estimated 350,000 cases -- in the world. Aside from a large influx of money, the most necessary changes to improve the health system are lowering the salaries of doctors and nurses, reorienting physician training toward primary health care, increasing the quality of existing health services, more efficient management, and better coordination between the Ministry of Health and the voluntary organizations.

At a global level, there is an urgent need for vaccines against major diseases which are not yet vaccine-preventable. This particularly includes bacterial and viral diarrhoeal diseases, acute respiratory infections, AIDS, malaria, schistosomiasis and meningococcal meningitis. There is also a need for more efficient vaccines against tuberculosis, for a new measles vaccine effective in the young child in the presence of residual maternal antibodies. Therefore, research aiming to define new ways to selectively induce protective responses which would fulfill the needs of immunization programmes, not only in terms of efficacy but also in terms of practicality, represents a real priority. Along this line, modern immunology should be a significant source of new tools to achieve the goal of developing a series of new vaccines which may potentially help to prevent millions of child deaths.

International travels are increasingly frequent. Beside malaria prophylaxis, the general practitioner will review several vaccinations.e Tetanus and poliomyelitis vaccines should be administered once every ten years. It will often be useful to give a protection against hepatitis A, and less often, against typhoid fever. The yellow fever vaccine, which may be required or recommended to visit several African and South American countries, is injected only by officially recognised centres. For some travels, vaccination against hepatitis B, meningococcal meningitis or, rarely, against rabies may be considered. The vaccine against cholera will never be administered, due to its lack of efficacy and high frequency of side effects. Travellers diarrhoea will be discussed, and a "pocket" treatment prescribed. Finally, general information will be provided, including those on STD.

Between October 1994 and January 1995 a field hospital saw nine cases of falciparum malaria associated with meningococcal meningitis among Rwandan patients residing in Kibumba refugee camp in Goma, Zaire. All except one presented with signs and symptoms suggestive of meningeal irritation; all but one responded to intravenous quinine and chloramphenicol or ampicillin. Two had recrudescence of malaria and responded to treatment with pyrimethamine-sulphadoxine (Fansidar). There were no sequelae seen. Meningococcal meningitis is uncommon but frequently fatal if it occurs in patients with falciparum malaria. Early diagnosis and treatment are urgent to decrease morbidity and mortality.

Recent advances in travel medicine include the use of computer resources to obtain information on outbreaks and recommendations to travelers, the introduction of atovaquone/proguanil as chemoprophylaxis and treatment for malaria, the use of azithromycin as an alternative in the self-treatment of traveler's diarrhea, and the combination of hepatitis A and hepatitis B vaccines. At the same time, new challenges continue to appear. Shifts in the distribution of infections, such as West Nile virus and dengue fever, underscore the need for up-to-date information. Well-known infectious diseases, such as polio, meningococcal meningitis, and influenza are appearing in unexpected ways and settings. It is increasingly clear that travelers, while at risk for infections, also play a role in the global dispersal of pathogens, such as certain serogroups of Neisseria meningitidis and influenza. Increasing drug resistance affects the choice of drugs for treatment and chemoprophylaxis, and decisions about use of vaccines. Newly identified adverse events associated with yellow fever vaccine have prompted enhanced surveillance after vaccination and careful scrutiny of appropriate indications for the vaccine.

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.

Despite spectacular progress in the eradication of infectious diseases, malaria and tuberculosis are making a comeback in many parts of the world. After years of decline, plague, diphtheria, dengue, meningococcal meningitis, yellow fever, and cholera have reappeared as public health threats. In the last 20 years [before 1997] more than 30 new and highly infectious diseases have been identified, including Ebola-type hemorrhagic fever, HIV/AIDs, and hepatitis C. Antibiotic resistance has also emerged during this period, and fewer new antibiotics are being produced because of high development costs and licensing. Drugs no longer offer protection or cure for many infectious diseases, and consequently more people need hospitalization with higher treatment costs. The causes of the appearance of new diseases and the resurgence of old ones include the rapid increase in international travel, the growth of mega-cities with high population densities, inadequate safe water and sanitation, food-borne diseases by the globalization of trade, and human penetration into remote animal and insect habitats. Meanwhile, resources for public health are being reduced, with the result that either the appearance of new diseases or resistance to drugs go unnoticed. A recent example is the human immunodeficiency virus, which went unrecognized until a large number of people got infected. For this very reason the 1997 World Health Day featured the theme of emerging infectious diseases and global response. Such forums are held to help countries rebuild the foundations of disease surveillance and control, while the public and private sectors may be encouraged to develop better techniques for surveillance to confront a common global threat.
