Jakoś tak się dziwnie składa, że dosłownie każde paskudztwo
tego rodzaju jest doskonale znane właśnie w Atlancie.
Ciekawe ...

      Marburg wcale nie jest "rownie smiercionosny jak Ebola" - smiertelnosc w
      wypadku zarazenia Marburgiem wynosi zwykle 25-30% (zalezy od szczepu), w
      wypadku Eboli Zair 90%-100%, a Eboli Sudan 50-60%. Co nie zmienia faktu, ze
      kazda taka epidemia jest tragedia. Smiertelnosc w epidemii w Angoli jest
      znacznie wyzsza (zmarlo 96 z 107 zarazonych osob), lecz jest to wynik
      niskiego poziomu opieki medycznej - prowincja Uige jest jedna z
      najbiedniejszych w kraju.

      to nie nowy wirus!!!!
      Nazywa sie tak bo pierwsza opisana epidemia mila miejsce w miescie
      Marburg (Niemcy, jezeli pamietam to koniec lat piecdziesiatych lub pocztek
      szesciesiatych ).
      Ludzie pozarazali sie od przywiezionych z Afryki malp.
      Smiertelnosc jest rzedu 25-55%(zalena od jakosci opieki lekarskiej).
      Natomiast co do CDC w Atlancie, Gorgia, USA.
      Jest to Center for Desise Control and prevention(cywilne) rzadowe USA
      (nie ogolnoswiatowe).
      USA ma jeszcze jedno centrum sponsorowane przez wojsko jest U.S. Army Medical
      Research Institute of Infectious Diseases (USAMRIID)ulokowany w Frederick MD
      (USA).
      Sa to 2 organizacje odpowiedzialnie za monitorowanie epidemii(lub podejrzenia
      epidemii) w USA. Bardzo czasto obydwie organizacje wspomagaja pomoca ogniska
      "zapalne" w innych krajach. Zajmuje im pomiedzy 24-48 godzin od otrzymania
      sygnalu do dostarczenia specjalistow na miejsce zdarzenia ze sprzetem
      niezbednym do pracy. Marburg wirus nalezy do tej samej rodziny co Ebola.
      Jedna z ostatnich (oglaszanych) epidemi byla pod koniec
      lat dziewiedziesiatych w centralnej afryce

        To moze ja podrzuce kilka faktow, bo wiedze ze niektorzy cos wiedza, choc nie
        do konca:

        Laboratory tests have identified Marburg virus as the causative agent in an
        outbreak of suspected viral haemorrhagic fever in Angola. Virus was detected 21
        March in samples from nine of twelve fatal cases.

        Retrospective analysis has now identified 102 cases in the outbreak, which
        dates back to October 2004. Of these cases, 95 have been fatal.

        Most cases are presently concentrated in Uige Province in the northern part of
        the country.
        Since the start of the outbreak, the monthly number of cases has progressively
        increased, but this increase could be the result of intensified surveillance.
        Around 75% of cases have occurred in children under the age of 5 years. Cases
        in adults include a small number of health care workers.

        Marburg virus disease has no vaccine or curative treatment, and can be rapidly
        fatal. In the present outbreak, most deaths have occurred between 3 to 7 days
        following the onset of symptoms.

        Past outbreaks indicate that close contact with bodily fluids of infected
        people, as may occur in health care settings or during burial practices,
        increases the risk of infection.

        WHO is supporting efforts by the Ministry of Health in Angola to strengthen
        infection control in hospitals, to intensify case detection and contact
        tracing, and to improve public understanding of the disease and its modes of
        transmission.

        Background
        Marburg virus disease is an acute febrile illness accompanied by severe
        haemorrhagic manifestations. The disease has an incubation period of 3 to 9
        days. In the earliest stage of infection, symptoms are non-specific and may be
        easily confused with more common diseases, including malaria, yellow fever, and
        typhoid fever. A severe watery diarrhoea, abdominal pain, nausea and vomiting
        are early symptoms, as are severe chest and lung pains, sore throat, and cough.
        A high proportion of cases develop severe haemorrhagic manifestations between
        days 5 and 7, most frequently affecting the gastrointestinal tract and the
        lungs. A characteristic rash usually appears at this time, sometimes involving
        the whole body.

        The disease was first identified in 1967 during simultaneous outbreaks
        affecting laboratory workers in Marburg and Frankfurt, Germany and in Belgrade,
        Yugoslavia. The outbreaks, which involved 31 cases and seven deaths, were
        subsequently linked to contact with infected monkeys imported from Uganda.

        The virus then disappeared until February 1975, when an acutely ill man with a
        recent travel history to Zimbabwe was admitted to a hospital in South Africa.
        Infection spread from the man to his travelling companion and a nurse at the
        hospital. The man died, but the other two cases recovered.

        In 1980, two cases, one of which was fatal, occurred in Kenya. In 1987, an
        additional single case, which was fatal, occurred in Kenya.

        The largest outbreak on record, which occurred from late 1998 to late 2000 in
        the Democratic Republic of Congo, involved 149 cases, of which 123 were fatal.
        The outbreak was initially concentrated in workers at a gold mine in Durba.

        Marburg virus disease occurs very rarely and appears to be geographically
        confined to a small number of countries in the southern part of the African
        continent. When cases do occur, the disease has epidemic potential, as it can
        spread from person to person, most often during the care of patients. For this
        reason, strict measures for infection control need to be applied during the
        management of cases. Containment of an outbreak of Marburg virus disease also
        requires the rapid tracing and isolation of contacts. Health education is
        needed to inform communities of the risks associated with traditional burial
        practices.

        Despite intensive investigations extending over several years, research has
        failed to find an animal reservoir of the virus or determine where it hides in
        nature between outbreaks.
