From August 2000 through January 2001, a large epidemic of Ebola hemorrhagic fever occurred in Uganda, with 425 cases and 224 deaths. Starting from three laboratory-confirmed cases, we traced the chains of transmission for three generations, until we reached the primary case-patients (i.e., persons with an unidentified source of infection). We then prospectively identified the other contacts in whom the disease had developed. To identify the risk factors associated with transmission, we interviewed both healthy and ill contacts (or their proxies) who had been reported by the case-patients (or their proxies) and who met the criteria set for contact tracing during surveillance. The patterns of exposure of 24 case-patients and 65 healthy contacts were defined, and crude and adjusted prevalence proportion ratios (PPR) were estimated for different types of exposure. Contact with the patient’s body fluids (PPR = 4.61%, 95% confidence interval 1.73 to 12.29) was the strongest risk factor, although transmission through fomites also seems possible.

Outbreaks of Ebola virus haemorrhagic fever have been reported from 1994 to 1996 in the province of Ogooué Ivindo, a forest zone situated in the Northeast of Gabon. Each time, the great primates had been identified as the initial source of human infection. End of November 2001 a new alert came from this province, rapidly confirmed as a EVHV outbreak. The response was given by the Ministry of Health with the help of an international team under the aegis of WHO. An active monitoring system was implemented in the three districts hit by the epidemic (Zadié, Ivindo and Mpassa) to organize the detection of cases and their follow-up. A case definition has been set up, the suspected cases were isolated at hospital, at home or in lazarets and serological tests were performed. These tests consisted of the detection of antigen or specific IgG and the RT-PCR. A classification of cases was made according to the results of biological tests, clinical and epidemiological data. The contact subjects were kept watch over for 21 days. 65 cases were recorded among which 53 deaths. The first human case, a hunter died on the 28th of October 2001. The epidemic spreads over through family transmission and nosocomial contamination. Four distinct primary foci have been identified together with an isolated case situated in the South East of Gabon, 580 km away from the epicenter. Deaths happened within a delay of 6 days. The last death has been recorded on the 22nd of March 2002 and the end of the outbreak was declared on the 6th of May 2002. The epidemic spreads over the Gabon just next. Unexplained deaths of animals had been mentionned in the nearby forests as soon as August 2001: great primates and cephalophus. Samples taken from their carcasses confirmed a concomitant animal epidemic.

OBJECTIVE: To assess the opinion of persons with HIV infection in Europe. METHODS: A cross-sectional survey of persons with HIV infection attending HIV/AIDS treatment centres or HIV support organizations in 11 European Union Member States was performed. A total of 2751 anonymous patient self-administered questionnaires were distributed between August 1996 and September 1997. The questionnaire contained 108 questions concerning a variety of topics about HIV care, including five questions on euthanasia. RESULTS: One thousand three hundred and seventy-one people with HIV infection completed the questionnaire, of whom 1341 (98%) responded to the questions concerning euthanasia. Seventy-eight percent of respondents agreed with the legalization of euthanasia in case of severe physical suffering, 47% if there was severe psychological suffering and 24% simply at the patient's request. For physical suffering and at a clear patient's request, accepted practices were: alleviation of pain with double effect (81%), medical euthanasia (62%) and physician assisted suicide (45%). Fifty percent would consider euthanasia for themselves if all treatment options were exhausted. Social indicators such as educational level and employment seemed to play a more significant role in determining attitudes towards legalization, and personal interest in, euthanasia than indicators related to disease status. CONCLUSION: In this study a majority of HIV infected persons in Europe favoured the legalization of euthanasia.

METHODS: Between August 1996 and September 1997, anonymous self-administered questionnaires were distributed to HIV-infected people in 11 European countries. RESULTS: A total of 1366 people completed the questionnaire (50% response rate). Of these, 194 (16%) had more than five negative HIV tests before being diagnosed as HIV positive, 179 (14%) were tested without consent and 192 (15%) were informed about the HIV positive test result by mail or by telephone. Of the 963 people who received a positive test result during a consultation, 247 (26%) reported that this visit lasted less than 10 min, 336 (35%) between 10 and 20 min, and 289 (30%) more than 20 min. Over half the total respondents (591, 54%) felt they did not receive adequate support when they were informed about being HIV positive, with 249 (19%) experiencing feelings of rejection. People who were diagnosed as HIV positive after 1994 reported more frequently receiving adequate support, information and understanding when the positive test result was revealed compared with those diagnosed before 1990. CONCLUSION: A large number of our study participants did not endorse the way HIV tests were conducted and positive test results revealed. Although there was an improvement over time in the way HIV tests were conducted, they often did not conform to international guidelines.
